Fuzzy strings don't contribute anything to the translations that the
users get to see. They are useful only for translators, but translators
fetch or receive their PO files from the TP. For nano, fuzzy strings
just bloat the distribution tarball.
These obsolete strings contribute nothing to the translations that the
users get to see. They are somewhat useful only for translators. But
as nano is registered at the Translation Project, translators fetch or
receive their PO file from there (or they keep their own archive), so
these obsolete strings are not getting lost. But for nano, they just
burden the distribution tarball.
Do the same as in the previous commit: re-evaluate the start of the
viewport when lines that are located above this viewport may have
changed. This is relevant when softwrap is on.
When only the trailing chunk of a line is displayed on the top row of
the screen, and the unindenting of this line leads to a reduction in
the number of chunks, then the starting point of the viewport needs
to be re-evaluated. For simplicity, do this always when something is
unindented.

For relatively inexperienced users (as most users of nano probably are)
it is far better that nano produces POSIX text files by default, where
each line ends with a newline character. This means that these files

last line), tools will see and process each line of them, and, while
editing, adding text at the end is easier.

Bug existed since the recognition of modified cursor keys on a Linux
console was introduced, in version 2.6.3, commit 290d278f.
This matches Pico's behavior. However, Pico doesn't add the quoting +
indentation to the line in which the selection ends, but this is wrong,
so nano does add it. Also, Pico doesn't account for partial quoting +
indentation at the start or end of a selection, but this is wrong, so
nano does.
Unlike a regular paragraph, marked text may have different quotes and
more than two types of indentation. Handle this by replacing deviant
quotes with the quote of the first line, and deviant indentation with
the indentation of the second line.
This is modelled after Pico's behavior. However, Pico won't do anything
if you do a full-justify while the mark is on. But this is unnecessarily
limiting, so, when the mark is on, nano will handle a full-justify and a
plain justify the same.
This currently does not handle the lead (quoting + indentation) in
justified selections, does not put mid-line justified selections onto
separate lines, and does not strip whitespace after the lead in justified
selections, the latter two of which Pico does. These behaviors are
forthcoming.
concat_paragraph() concatenates a paragraph into a single line, and
rewrap_paragraph() rewraps that line into multiple lines again.
These two will be needed when the justifying of marked text is added.
Instead of passing 'quote_len' to these functions, calculate it directly
in them.
This will be needed when the justifying of marked text is added. When
unmarked text is justified, it is a single paragraph and by definition
has a uniform quoting part. But marked text may be a jumble of lines
that have different quoting parts.
Option -J (--guidestripe) takes a column number as argument and then

Jumping to the first or last line of the buffer doesn't have anything

When multiple buffers are open, the edit window says "Close" for ^X
instead of "Exit" (when one buffer is open). In the help viewer ^X
says "Close". Apparently the idea is that ^X should say "Exit" only
when pressing ^X leads to exiting from nano. Pressing ^X in the file
browser does not exit from nano, so make it say "Close" instead.
(The help viewer says "Close" since version 2.8.6, commit 934a2192.)
When using --preserve, ^S and ^Q are "eaten" by the terminal and
do not reach nano: they have no effect in nano, so the help lines
and the help texts should not mention these shortcuts.
Also, to keep the help lines in the help viewer neatly arranged,
^L is not bound there when --preserve is used.
Not stepping beyond the last line of the paragraph means that the
length of the paragraph is always the difference in line numbers
(between first and last line of the paragraph) plus one.
When leaving the mark on while justifying and then undoing the
justification, things are likely to get messed up. My applying
David's patches only partially caused this breakage.
This fixes https://savannah.gnu.org/bugs/?55074.
Only the first search for a paragraph needs to check whether we're
currently in the middle of a paragraph. When the 'while' loop for
a full justify is executed, all calls of find_paragraph() start
either on the first line of a paragraph or between two paragraphs.
To find a paragraph, what needs to be done is:
a) When not in a paragraph, move forward until we find one, if any.
b) When in a paragraph but not at its start, move back to its start.
c) Move forward to the end of the paragraph, if any.
When, in the 'while' loop for a full justify, 'filebot_inpar' becomes
TRUE, it means that EOF has been reached and find_paragraph() should
not be called again. To allow 'filebot_inpar' to convey this meaning,
it should not be set to TRUE elsewhere, so another boolean is needed
for setting the correct length of the final line of the cutbuffer.
This fixes https://savannah.gnu.org/bugs/?55086.
The removal of the x-coordinate handling affected this. Reshuffle things
so that we can check for it after we have moved (the same way we check for
it at the beginning of the function before we move) without having to set
'quote_len' and 'par_len' unnecessarily.
Also, adjust some comments accordingly.
Move detecting the final line of the paragraph to find_paragraph(),
since a paragraph of which the final line is the last line of the
buffer will still be that way after being justified.
Also, move all x-coordinate handling to do_justify(), since it only
applies to the current buffer.
Move a few references to the current buffer to do_justify(). Also,
the check for being at the end of the buffer needs to be done after the
first paragraph is found, so that the existing behavior of finding an
initial paragraph regardless of cursor position is preserved.
The functions do_para_begin() and do_para_end() can now move through any
buffer, while the functions do_para_begin_void() and do_para_end_void()
operate on the current buffer. The latter function also returns TRUE
if the last line in the buffer is part of the paragraph.
Remove the handling of 'edittop', 'totsize', and the mark, to make the
function more general, which is needed to make it undoable eventually.
This breaks the function somewhat. Fixes for this are forthcoming.

The bindings for F1 to F12 are there for compatibility with Pico.
But Pico does not know anything about F13 to F16; for unknown reasons
they were added to nano. They seem hardly useful: normal keyboards
do not have the F13 to F16 keys, and very few people know that they
can "produce" those keys by holding Shift with F1 to F4. But typing
Shift plus F1 to F4 are just as "hard" as, for example, M-G and M-W,
so why anyone would want to use the first ones...? Especially since
many other functions of nano can only be accessed through Meta and
Control combinations.
Furthermore, F13 to F15 haven't been shown in the help texts since
version 2.3.3, so for more than four years no new user will have
learned about those keystrokes.
The rare user who wants these strange bindings can easily make them
herself.
The help lines will help differentiate this mode from normal editing
mode, and will tell the user how to jump to other messages.
This is a third step to address https://savannah.gnu.org/bugs/?54714.
When --view is used without --ignorercfiles, the user could view
other files anyway if they had 'set multibuffer' in their nanorc.
So, just make this the default when --view is used, also because
"multibuffer" cannot be toggled once nano is running in view mode.
When the viewing of other files in view mode should not be allowed,
one should now additionally use --restricted.
The 'wrap_at' variable, removed in commit e90b7cf4, is actually needed

The new function, justify_paragraph(), takes a quote length and a
paragraph length (which it should get from find_paragraph()), and
runs the paragraph at (current, current_x) through justify_format().
Move some fragments out of the justifying loop, and adjust/clarify comments
to account for the changes. This will allow some of the code to be cleaned
up and simplified in the next commits.
This allows running the speller (default binding: ^T) also on files for
which a linter has been defined. This makes it possible to spell check
comment blocks in source files, for example.

Only for BACK and DEL was the first call to update_undo() -- all other
types of action would call add_undo() first, so for them the action in
update_undo() would never be different, but the line number might have
changed (like for ENTER and INSERT), so for them exceptions needed to
be made, which was wasteful.
This addresses https://savannah.gnu.org/bugs/?54728.
The binding was made only to have *something* bound by default to the
'cutwordleft' function. But now that <Ctrl+Shift+Delete> is available
*and* visible in the help text, the M-| binding is superfluous.
When using the internal spell checker, the message gets overwritten
immediately by "Creating misspelled word list...", and when using
the external spell checker, nano immediately exits from curses mode
and thus the message disappears (when in a terminal emulator) or it
soon gets wiped by the spell checker (when on a Linux console), thus
creating a little flash on the bottom row, which we can do without.
In the past, SIGWINCHes were responded to immediately (which was madness),
but since commit 75d64e67 all a SIGWINCH does is set a flag so that, when
the time comes to update the screen, nano knows the dimensions may have
changed. The mentioned commit removed most blockings and unblockings of
SIGWINCH, but not this one.
Assume that 'print' and 'exec' are statements when they are followed
by whitespace, and are functions otherwise. This does not highlight
"print'x'" nor "print{x}", but these statements are poor style.

So that the user can do 'bind ^H cutwordleft all' in their nanorc
to make ^H (and sometimes also <Ctrl+Backspace>) delete the word
to the left of the cursor while <Backspace> continues to delete
just one character.
As the statusbar() function will write the position directly to the
terminal when not in curses mode, the final part of this position
message will seem to be after the prompt when exiting from nano.
The cursor position will get written correctly to the status bar
anyway, because returning from suspension enters a fake key into
the keyboard buffer, and this key elicits an update of the display.

Bug existed since version 2.9.4, commit 54103d8e.
(The offending commit meant in the previous commit was 60f1090d.
My mistake.)
When curses gives no code for Ctrl+Shift+Delete, do not fall back
to KEY_BACKSPACE, because then ^H and/or <Backspace> get bound to
'cutwordleft'.
This fixes https://savannah.gnu.org/bugs/?54642.
Bug was introduced with version 3.0, commit e6429e78.
That is, wait with deleting words until they start under cursor,
so the user can see which word is goin to be eaten, and join lines
only when the cursor already sits at the edge of a line.
On FreeBSD and NetBSD (when reached through ssh from a Linux machine)
this has the absurd effect of making <Ctrl+Backspace> do a 'cutwordleft'
by default, out of the box, without needing any rebindings. Weird, but
wonderful, because the ideal behavior.
Also ensure that <Shift+Delete> always does a Backspace.
This makes that we have the following set of "congruent" keys:
<Tab> moves text to the right,
<Shift+Tab> moves text to the left,
<Delete> "eats" a character to the right,
<Shift+Delete> "eats" a character to the left,
<Ctrl+Delete> "eats" a word to the right,
<Shift+Ctrl+Delete> "eats" a word to the left.
Also, don't partially color "..." as an operator, because it isn't,
and color also the unary operator "#".

There are at least three other ways to achieve the thing that it did:
^End, M-/, and ^W^V. No need to have a fourth way by default.
For symmetry, also unassign the corresponding binding for M-|.
The 'cutwordright' function has gotten ^Delete as its default binding,
so the 'cutwordleft' function needs a default binding too -- also to
keep the items on the two help lines nicely paired. M-| was chosen
because it is close to the Backspace key on many keyboard layouts.
Print routines are not asynchronous-safe.
But... the only reason the call of kill() could return an error code

In theory it would be possible to allow rebinding also F17...F63,

Instead of being entirely silent when ^] is hit after whitespace
or punctuation, report what is lacking -- similar to M-] saying
"Not a bracket" when the cursor is not sitting on a bracket.
This makes the ^] keystroke more discoverable.
This makes things symmetrical: ^W starts a forward search, ^Q starts
a backward search, M-W searches the next occurrence forward, and M-Q
searches the next occurrence backward.
The Tabs-To-Spaces toggle is moved to M-O, and thus the More-Space
toggle is no longer bound by default.
When using option -K on an xterm-like terminal, pressing <Shift+Del>,
<Alt+Del>, or <Ctrl+Del> would enter "2~", "3~", or "5~", respectively,
into the buffer. Now it will just report an "Unknown sequence".
The crawl needs at least five rows to be perceived as a crawl, and
the widest line is 31 characters (ignoring translations, which might
be even longer). Formerly, when only two or three rows were available,
nothing was shown at all, which was puzzling. So, better do the credits
only when there is room enough for them, and print a message otherwise.
When switching to a different buffer, don't just show its name but
also the number of lines it contains. This is useful extra info.
Then use this same message when at startup multiple files are opened
and (after reading them all) we switch back to the first buffer.
(This loses, when multiple files are opened, the information about
format conversion that nano still shows when a single file is opened,
but... this bug has shown that people don't really look at this line
anyway, so... let it be. The info can still be seen when writing out
the file with ^O.)

Unlike glibc, which in getc() locks the file only when it is needed,
FreeBSD and Bionic libc will always lock the file, causing a massive
slowdown, as the system has to create and destroy a mutex each time
getc() is called.
Avoid that massive overhead by locking the file before starting to read
and unlocking it after reading is complete, and using getc_unlocked() to
read each byte. This makes reading on FreeBSD/macOS and Android anywhere
from 2 to 6 times faster, and on glibc roughly seventy percent faster.

The Alt key together with Shift is a special workaround for when
Shift+PgUp and Shift+PgDn don't work on the user's terminal. But
probably it is more common to use the Ctrl key together with Shift
to select larger pieces of text. So mention this possibility.
And in the bargain get rid of some duplicate code.
This makes a binary without UTF-8 support slightly slower, but that's
not important -- it is more than fast enough anyway. Important is that
the most used and longest code path, the UTF-8 case, becomes faster.
Note that 'is_cntrl_mbchar()' will fall back to 'is_cntrl_char()' for
a non-UTF-8 build, so the deleted piece of code really was equivalent
with the remaining piece for that case.
Take our cue from undoing/redoing line joins: when they take place on
the magicline without --nonewlines, they produce undo/redo items that
don't do anything to the text, but still position the cursor properly.
Reshuffle a bit of code so that we can do the same for magicline cuts.
This fixes https://savannah.gnu.org/bugs/?54032.
Again, if the most significant bit of a UTF-8 byte is zero, it means
the character is a single byte and we can skip the call of mblen(),
*and* if the character is one byte it also occupies just one column,
because all ASCII characters are single-column characters -- apart
from control codes.
This partially addresses https://savannah.gnu.org/bugs/?51491.
For UTF-8, if the most significant bit of a byte is zero, it means the
character is just a single byte and we can skip the call of mblen().
For files consisting of pure ASCII bytes (between 0x00 and 0x7F), this
change reduces the counting time of mbstrlen() by ninety six percent.
This partially addresses https://savannah.gnu.org/bugs/?50406.
When mbtowc() is never called with anything less than MAXCHARLEN as
the length parameter, it will apparently not get confused and will
not need to be reset.
The variable 'last_action' is set at the end of these functions,
serving to prevent a fresh action from being merged with an older
action further down on the stack. Setting 'last_action' before
exiting from undo()/redo() makes no sense.
Also adjust a sideways related old Changelog item.

Otherwise the first line of a multiline /*...*/-comment would be
seen as quoted and thus *not* as the first line of a paragraph.
In the code, use "/{2}" to prevent the remainder of the line
getting colored as a comment.
The paragraph-aware indenting is needed only when automatic long-line
wrapping is on (that is, when not using 'nowrap': when writing prose).
When writing code, the user most likely uses --nowrap, which will make
nano indent a new line always to the same amount as the preceding line
-- when --autoindent is in effect, of course.
The only time that feedback about the number of lines written is *not*
wanted is when writing a temporary file.
This fixes https://savannah.gnu.org/bugs/?54025.
Plus one that automake recognizes: if. Color them only at the start
of a line. Also color all possible assignment sequences (surrounded
by spaces to not color the ones in shell fragments), and add some
comments.
When doing autoindentation, and the next line is not the start of
a new paragraph, then use the indentation of that line for the new
line, as it is more likely to have the desired indentation -- the
current line might be the start of the paragraph and thus could
have a deviant indentation.
Pico wraps at the last blank character before or on the target column;
if there is no such blank, then it will wrap at the first blank *after*
the target column -- when it can wrap, it will wrap. Nano should do
the same (and judging from the comments, it intended to do the same),
instead of turning the paragraph into a single unwrapped line.

In the past, the argument could be either a regex or a literal string,

For cuts, pastes, and inserts, the lines have already been renumbered;
for indents, comments, and replacements, the line numbers cannot have
changed. (And anyway, variable 'f' is not set for those cases.)
Only when lines get split (ENTER) or fused together (JOIN) do the later
lines need to be renumbered. This mirrors what is done for do_redo().
The 'f' variable is used only in the ADD, BACK, DEL, ENTER, JOIN, and
REPLACE undo/redo cases. So, avoid making a somewhat costly call when
it is entirely superfluous. Rearrange the undo types to make checking

Instead of always calling sctofunc(), it is now only called when

no need for a refresh has been established yet.
Commit bb667beb removed do_gotolinecolumn_void() from the MWHEREIS

is no longer any need to check for this one special case.
The slash is easier to read than the underscore (which almost
disappears at the bottom of the screen), and easier to type
(no Shift needed on a US keyboard), and it kind of harmonizes
with the ^\ for Replace and the M-/ for End-of-buffer.
When using --smooth or 'set smooth', the screen should scroll the
minimum amount needed to get the cursor back into view. (The only
exceptions are search, undo, and redo -- when there the cursor goes
offscreen, the cursor line is centered.)

Commit 28beb3f added the 'forreal' parameter to prevent spotlight() from
placing the cursor wrongly due to an invalid placewewant. However, since
the variable-width softwrap overhaul (specifically, since commit 8490f4a),
place_the_cursor() no longer checks placewewant, so the parameter is no
longer needed.
Furthermore, dropping 'forreal' and thus always setting current_y won't
affect the operation of spotlight(), since the only functions that use
spotlight() (do_replace_loop() and do_int_spell_fix()) both call
edit_refresh() beforehand, which means that current_y will already
have been set to the value it will be set to again.
The function place_the_cursor() assumes that the viewport is up to date,
i.e., that current is in range of edittop. When uncutting or inserting,
however, place_the_cursor() gets called on the out-of-date viewport
first, and then a screen refresh is scheduled (which would put the
viewport up to date). This is backwards: the refresh should come before
the cursor placement, and the only reason it works anyway is because the
cap on the number of chunks to move backward papers over the problem by
keeping current_y in screen range regardless.
Fix this properly by simply setting current_y to the bottom row of the
screen instead of calling place_the_cursor(). This value of current_y
is only ever used when in smooth scrolling mode and the insertion (or
paste) pushed the cursor offscreen. In other situations, this value is
overridden when place_the_cursor() gets called after a screen refresh.
After that fix, the cap on the number of chunks to move backward is no
longer needed.
When not using --smooth (nor 'set smooth'), and a line near or beyond
the end-of-file is addressed with the + command-line argument, then

If get_softwrap_breakpoint() can't find whitespace in screen range, it

spotlight() now displays softwrapped lines chunk by chunk instead of all
at once. Since softwrapped lines are no longer of constant width, the
latter approach would fail if softwrapping breaks the spotlighted text.
Instead of taking a string, spotlight() now takes the starting and ending
columns of that string. Also, its handling of softwrapped lines is now
split off into a separate function, spotlight_softwrapped().
get_chunk_row() and get_chunk_leftedge() now become wrappers around
get_chunk(); the latter is only used directly in place_the_cursor()
when we need to get both the row and the leftedge. get_chunk() now
uses the proper formula to implement varying chunk width.
Since chunk width now varies, place_the_cursor() sets the x position
relative to the leftedge in a different way that works regardless
of chunk width, update_softwrapped_line() loops until it gets all
softwrap breakpoints instead of calculating the full length in
advance and getting one full row at a time, the chunk iterators
now count leftedges instead of rows, and fix_firstcolumn() does a
full recalculation of the chunk that firstcolumn is on instead of
simply shifting it back.
Also, in update_softwrapped_line(), when a line's softwrap breakpoint
is before the last column of the edit window, a ">" is now added to
the end of it.
The workaround in place_the_cursor() for when two-column characters
straddle the edge of the screen is removed, as it's no longer needed
now that chunks end before such characters.
Furthermore, do_home() and do_end() use xplustabs() instead of
placewewant again when calculating the leftedge, since placewewant
refers to a column that may or may not be available (if it's not,
the cursor will be placed wrongly). Make get_edge_and_target() use
xplustabs() instead of placewewant for the same reason; this also lets
us simplify get_edge_and_target(), since xplustabs() will never be
greater than strlenpt(). Finally, since do_end() now has to calculate
rightedge as well as rightedge_x, use the former to implement the same
time-saving optimizations as in do_home().
The cursor is not yet adjusted when we try to go directly to a column
past the end of a softwrap breakpoint, and placewewant handling in the
vertical movement code is not yet adjusted for varying chunk lengths,
but fixes for these are forthcoming.

The new function find_softwrap_breakpoint() returns the column number

If the end of the text is reached while searching for a wrapping point,

Instead of calling total_refresh(), put a no-op key into ncurses' buffer,
so that, when nano actually does return out of suspension (through 'fg'),
this key will be read and discarded, upon which nano will go sit and wait
for the next key, just before which it calls doupdate(). The latter is
all we need to get the entire screen restored.
This also fixes https://savannah.gnu.org/bugs/?51131 for "tiny".
When receiving a SIGCONT, don't call regenerate_screen() directly
but act as if a SIGWINCH occurred. Also insert a dummy key, and
thus let the relevant input routine redraw the relevant subwindows.
Use KEY_F0 as the dummy key, as both Ncurses and Slang know it, and
it should normally do nothing at all.
This fixes https://savannah.gnu.org/bugs/?51124.
When we are in the file browser, browser_refresh() will take care of
redrawing the title bar and the file list, so total_refresh() should
leave those two subwindows alone in that case.

Achieve this by making the suppression flag global, so that we can

Whenever 'make' is run, it should check whether the revision has

Instead of always stepping back four bytes and then tentatively
moving forward again (which is wasteful when most codes are just
one or two bytes long), inspect the preceding bytes one by one
and begin the move forward at the first valid starter byte.
This reduces the backwards searching time by close to 40 percent.
Also when toggling the help lines back on or the extra editing space
back off, keep the cursor near the bottom of the screen if it /was/
there, instead of centering it -- if smooth scrolling is on, that is.
This supplements the fix for https://savannah.gnu.org/bugs/?50933.
When the editing space gets narrower, either by toggling line numbers on
or making nano's window smaller, and when the cursor is near the bottom,
it can be pushed offscreen. In that case, don't get it back onscreen by
centering the current line but by putting it on the bottom row. This
makes for a smoother experience.

The bottomwin has just been refreshed by update_the_statusbar(),
and it should not be the responsibility of the prompt routines
to keep the edit window up to date, as they don't write anything
there.
Things have morphed over time and display_buffer() no longer actually
displays the buffer -- it just displays the title bar, precalculates
the multiline color info, and schedules a refresh of the edit window.
If the length of the haystack is smaller than the length of the needle,
this means that also the length of the tail will be smaller -- because
pointer will be bigger than or equal to haystack -- so the pointer gets
readjusted to be a needle length before the end of the haystack, which
means that it ends up /before/ the haystack: thus the while loop will
never run.
On average, this saves some 200 nanoseconds per line.
This avoids https://savannah.gnu.org/bugs/?49912 while at the same time
avoiding to draw the edit window twice in a row -- the first drawing
would use a wrong margin, which results in a visible and irritating
shift left or right of the content upon the second drawing.

An iterator should not be called "start_col", because it is only the
starting column at the very beginning.
Also, start_col (after the rename) can never be /larger/ than column.
Since the help text is searchable, an <End> would go to the end of the
text but would leave a blank line above the statusbar -- a blank line
that wasn't there before, and that is not reached when simply holding
down <Down> all the way from the top.
When nano has multiple files open, closing a help buffer should
not switch to the next buffer in the ring but to the preceding one,
because it was from there that the help screen was invoked.
However, prefer moving the starting point of the text backwards over
moving it forward, so that of the same paragraph more text is shown
instead of less. But scroll an empty line out of view -- no text is
"lost" then.
Allow the user to search in a help text with ^W and M-W.
Achieve this by not writing the help text directly to the screen
but first writing it to a temporary file and then opening this file
in a new buffer, and treating it specially: the normal file-reading
feedback is suppressed, the titlebar shows the headline of the text,
the cursor is hidden, and the menu is limited to just the up and down
movements and searching.
This fulfills https://savannah.gnu.org/bugs/?28994.

The cursor needs to be placed in its proper spot in the edit window
/only/ when nano is about to accept input from the user and needs to
show where this input will go.
(This might cause a scrolling issue to appear, because reset_cursor()
does not just place the cursor, it also recomputes current_y, which
is used in several places to determine whether and how much to scroll.
If it so happens, we'll deal with that fallout later.)
This also groups ^I and ^M together, and cutwordleft and cutwordright
(when they are bound). It furthermore makes that less pairs are now
mixed and instead consist of either two Ctrl or two Meta combos. In
short: it looks better in the default config. The only sacrifice is
that Verbatim is now split off from the other "inserting" keys.

The interval 2013-2017 for the Free Software Foundation is valid

To make dynamic Home and End work properly when double-width characters

When Enter is pressed while the cursor is exactly on the current

When a multi-column character straddles a chunk boundary, and the
preferred column (placewewant) for the cursor is zero, cheat: show
the cursor not where the character starts but on the beginning of
the next row. This makes the cursor move smoothly in the leftmost
column of the screen when using <Up> and <Down> and such, instead
of jumping around.
In this way the scrolling logic won't get confused and the screen
will scroll properly when stepping beyond the top or bottom row.

If we're using the bundled gnulib regex module, then assume REG_ENHANCED

When UTF-8 is available, use actual arrows instead of untranslated words
to indicate the cursor keys. This was already done for the combinations
with Ctrl but not yet for the plain cursor keys.
The unshifted shortcuts are easier to type, and also less confusing in
my eyes. Putting them first means they get shown in the help lines,
and get listed first in the ^G help text.
(I would also like to put ^- first instead of ^_ (because the latter
is hard to see when using the default inverse video for shortcuts),
but on several terminal emulators Ctrl+- reduces the font size.)
Use futimens() instead of utime() to change the timestamps on a backup

Import the relevant gnulib module to make sure futimens() is available.
If we're using the bundled gnulib regex module, then assume word boundary

If edittop is partially offscreen before we scroll, and it gets

The iswspace() was only used when iswblank() was missing. The latter

Mention the ability to use <Tab> in the search history, the ability

The "./" is a shorthand for "current working directory".
It is better to specify it, because it differs from what
Pico does: reading always from the user's home directory
no matter where the editor was started.
Only use the "from" thing when an operating directory is in effect,
because /only/ then the indicated directory can be something other
than "./".
Also, make it so that there is no space before the colon.
Put all the movement keys together, in order of ascending stride.
Also, move the Undo/Redo keystrokes further up, so that, when the
user has a somewhat wider terminal than the usual 80 characters,
these keystrokes will be shown -- they are far more interesting
than the ^Y and ^V ones, for which PgUp and PgDn can be used.
If the number of columns in the edit window changes (which currently
only happens in two places: in regenerate_screen(), called when the
window is resized; and in main(), when line numbering mode is toggled),
the display will break if we're in softwrap mode and firstcolumn is
nonzero. This is because the column width of softwrapped chunks has
changed, and firstcolumn is no longer the starting column of a chunk,
an assumption that all code using firstcolumn relies on.
To fix this problem, add a new function, ensure_firstcolumn_is_aligned(),
to adjust firstcolumn to the starting column of the chunk it's on, and
use it when the number of columns in the edit window changes.
(Note that this function uses the simplest possible fix, and could
probably be made more sophisticated.)
In do_replace(), replacing text may change firstcolumn if the next match
is offscreen, and replacing text after that will not change it back. In
order to keep the viewport unchanged, we have to save and restore not
just edittop, but firstcolumn as well.
In do_int_spell_fix(), spell-checking text may change firstcolumn if
the next match is offscreen, and spell-checking text after that will
not change it back. In order to keep the viewport unchanged, we have
to save and restore not just edittop, but firstcolumn as well.
In do_justify(), justifying text may change firstcolumn if the paragraph
ends offscreen, and unjustifying the text again will not change it back.
In order to keep the viewport unchanged, we have to save and restore not
just edittop, but firstcolumn as well.
Copying text involves first cutting it and then quickly pasting it back.
However, cutting the text may change firstcolumn if the mark is offscreen.
To keep the viewport unchanged, copy_text() has to save and restore not
just edittop, but firstcolumn as well.
Now that we can add text to the bottom right corner of the screen
without scrolling the full line onscreen, do_output() needs to refresh
the screen in that case, since it would put the cursor offscreen
otherwise. Accomplish this by borrowing logic from do_right().
In do_up() when scroll_only is TRUE, if we're at the top of the screen
in softwrap mode, it's not enough to check that edittop is on fileage.
We also need to check that firstcolumn is zero.
In do_up() when scroll_only is FALSE, if we're at the top of the screen
in softwrap mode, current_y should be zero. This is equivalent to how,
in do_down() when scroll_only is FALSE, current_y is (editwinrows - 1)
at the bottom of the screen in softwrap mode. Since edittop can now
be partially scrolled off the screen even when it takes up the entire
screen, checking for edittop's being equal to openfile->current->next
there no longer applies.
The new function, update_softwrapped_line(), is called from inside
update_line() when softwrap mode is on, so that existing calls remain
unchanged. It takes no index, instead displaying edittop from column
firstcolumn, and all other lines from column zero.
If current is on edittop, it's displayed using the edittop rules, but
this is not a problem: if current[current_x] is above edittop at column
firstcolumn, it's offscreen, and that should be handled before calling
update_line() anyway.
Together with the preceding bunch of changes,
this fixes https://savannah.gnu.org/bugs/?47667.
Make current_is_above_screen() check for current[current_x] being above
edittop at column firstcolumn, and make current_is_below_screen() start
counting down from edittop at column firstcolumn instead of edittop at
column zero. This means that both functions now account for softwrapped
chunks properly.
Actually enable scrolling edittop partially off the screen by making
edit_scroll() and adjust_viewport() use firstcolumn properly when
iterating through softwrapped chunks in softwrap mode, or lines in
non-softwrap mode.
In non-softwrap mode, firstcolumn should still always be zero, because
it's initially set to that, and because passing it through the iterators
will maintain it at that.
This fixes https://savannah.gnu.org/bugs/?49100.

We want to be able to scroll the line at edittop partially off the
screen. For this to be possible, the new variable firstcolumn stores
the starting column of the viewport -- the starting column in the line
that edittop points to.
Since firstcolumn is used by go_back_chunks() and go_forward_chunks(),
it can't be completely #ifdefed out when NANO_TINY is set, but outside
of softwrap mode it should always be zero.
Currently firstcolumn is initialized to zero, reset to zero when
toggling softwrap mode off, and reset to zero when switching buffers
while softwrap mode is off. It's otherwise unused, but its uses are
forthcoming.
Since all lines can be partially scrolled off the screen now
(except for the top line of the edit window, which is forthcoming),
ensure_line_is_visible() is no longer needed.
Since all lines can be partially scrolled off the screen now
(except for edittop, which is forthcoming), the maxlines global
variable and its computation mechanism are no longer needed.
Use go_back_chunks() and go_forward_chunks() to move a screenful of
lines or chunks up or down, instead of using special computations in
the softwrap case.
Use go_back_chunks() and go_forward_chunks() in do_up() and do_down()
(instead of using a special and complicated computation in do_down())
so that they now properly move vertically to the previous/next chunk
in softwrap mode. This also means that do_left() and do_right() will
now properly move vertically at actual line boundaries.
Use the new "unclever" functionality of Home and End to make do_left()
and do_right() move properly to the end of the previous chunk or to the
start of the next chunk in softwrap mode when crossing a line boundary.
(Furthermore, doing Up plus End, or Down plus Home, does all needed
screen updates, which simplifies the code.)
The do_left() and do_right() functions don't yet properly move vertically
at line boundaries, but that will be fixed once do_up() and do_down() are
updated for softwrap mode, which is forthcoming.
This fixes https://savannah.gnu.org/bugs/?49384.
Add the parameter be_clever to both functions. When be_clever is FALSE,
smart home and dynamic home are disabled in do_home(), and dynamic end is
disabled in do_end(), so that these functions only move to the beginning
or end of the current line or chunk.
This simple home and end functionality is needed to improve do_left()
and do_right()'s horizontal behavior with softwrapped chunks, which is
forthcoming.
Make do_end() more useful in softwrap mode: let it move to the end of the
current chunk instead of the end of the line; only when already at the end
of a chunk, let it move to the end of the line. This is "dynamic end".
Make do_home() more useful in softwrap mode: let it move to the beginning
of the current chunk instead of to the beginning of the whole line; only
when already at the beginning of a chunk, let it move to the beginning of
the line. This is called "dynamic home'.
The above rules are ignored when --smarthome is in effect and the cursor
is somewhere in the leading whitespace of a line -- then the cursor is
moved to the first non-whitespace character of the line.
These improvements will eventually make do_home() and do_end() take
parameters. Since the global function lists can hold only functions
without parameters, preemptively add do_home_void() and do_end_void(),
and make the global function lists use them.
Use go_back_chunks() and go_forward_chunks() to move from the row
current_y is on to the row mouse_row is on. Now softwrap mode and
non-softwrap mode will behave the same way when we can scroll edittop
partially off the screen, which is forthcoming. Accordingly, remove
the call to ensure_line_is_visible(), as it no longer applies.
The old code did work, but it behaved differently between softwrap mode
(which counted down from edittop) and non-softwrap mode (which counted
up or down from current_y to take less time, and used a double loop to
keep current from going to NULL).
The new code counts up or down from current_y in both softwrap mode and
non-softwrap mode. In non-softwrap mode, it also avoids the double loop,
since go_back_chunks() and go_forward_chunks() keep the filestructs they
operate on from going to NULL.
Use go_back_chunks() to adjust edittop, instead of special casing
the computation of goal when softwrapping. Now softwrap mode and
non-softwrap mode will behave the same way when edittop can be
partially scrolled off the screen, which is forthcoming.
(Note that the top line of the screen can't be partially scrolled
yet, so we have to work around that for now.)
Use go_back_chunks() and go_forward_chunks() to adjust edittop and to
move up or down to the scrolled region before updating the rows there.
Now softwrap mode and non-softwrap mode will behave the same way when
we can scroll the top line of the screen partially off the screen,
which is forthcoming.
(Note that the top line of the screen can't be partially scrolled yet,
so we have to work around that for now.)
Not drawing a line on a row if we're on the top row and scrolled down,
or if we're on the bottom row and scrolled up, will only work properly
if the line on that row takes up only that row. The latter might not
be the case in softwrap mode: if the line occupies multiple chunks and
begins on that row -- in that case none of the chunks would be drawn.
Add the new functions current_is_above_screen() (which doesn't account
for softwrapped chunks yet, but will when we can scroll edittop partially
off the screen, which is forthcoming), current_is_below_screen() (which
determines whether current[current_x] is past the softwrapped chunk at
the bottom of the screen), and current_is_offscreen() (the union of the
previous two functions).
edit_redraw() and edit_refresh() now use current_is_offscreen() to check
whether they should adjust the viewport, and adjust_viewport() now uses
current_is_above_screen() to determine whether current is on or below
the screen in FLOWING mode.
Add the new function less_than_a_screenful() to accomplish this.
It uses go_back_chunks() to count the number of softwrapped chunks
between the end point and the starting point of the paste.
Now softwrap mode and non-softwrap mode behave the same way when
uncutting fewer than editwinrows rows of text. Accordingly, remove
the call to ensure_line_is_visible(), as it no longer applies.
Use go_forward_chunks() to count softwrapped chunks between the current
cursor position and the bottom of the file. Now softwrap mode and
non-softwrap mode behave the same way when moving to a line and column
non-interactively, instead of the former's always centering the screen.
These functions, go_back_chunks() and go_forward_chunks(), take a number
of softwrapped chunks (screen rows) to move, a pointer to a buffer, and
a location (specifically, a starting column of a softwrapped chunk). If
they move successfully, they will update the buffer pointer and location
to point to the beginning of the softwrapped chunk they moved to.
Since non-softwrap mode is effectively just a subset of softwrap mode
in which every line takes up one chunk, these functions also work in
non-softwrap mode. In this case, their starting column will always be
zero, as it would be in softwrap mode on a line that takes up one chunk.
Nothing uses these functions yet, but that is forthcoming.
Instead of redetermining the entire span of the converted string,
simply move one character left, and then bite it off to make place
for the trailing $.
If the last two columns of a row would be taken up by a double-width
character (and the line is longer than that), don't print it, because
it wouldn't leave any room for the $ character.

On a system with up-to-date GNU tools, this does not change
the size of nano's binary.
We start off with importing only a few modules, although we
don't yet delete the fallback logic for them.
The gettext-0.18.3 release was made in Jul 2013, while the 0.11.5
release was made in Aug 2002. Time to update :).
Also drop all the bundled gettext m4 files. When you run autogen.sh,
these will get copied in automatically for you.
The autoconf-2.69 release was made in Apr 2012.
The automake-1.14 release was made in Jun 2013.
Update the requirements so we know we can rely on macros/features
available in those versions.
The mark only needs to be off when calling replace_marked_buffer(),
because this indirectly calls ingraft_buffer(), which fiddles with
the end points if the mark is on.
Running strlenpt() on a string that takes up more than 80 columns
(the width of an average terminal) takes /more/ time than simply
converting an extra character (the one that will be overwritten
by the "$" at the edge of the terminal). So... just convert one
more character than necessary when the line is overlong. In the
most common case, however, the line will fit fully onscreen, and
we save a whole call of strlenpt().
Since we only need span columns of the string, stop scanning the string
as soon as we have that many columns, instead of scanning the string all
the way to the end. This speeds up the conversion of very long lines.
Replace partitioning with calls to extract_buffer() and ingraft_buffer().
In addition to pasting the unjustified text back into the buffer at
current[current_x], ingraft_buffer() also deals with renumbering and
updating totsize, so do_justify() doesn't need to do those anymore
when unjustifying.
With read_file() revamped, it now uses partition_filestruct() indirectly
via ingraft_buffer(), so we can't use partition_filestruct() to replace
marked text in the alternate spell checker anymore without segfaulting.
Add the new function replace_marked_buffer() to accomplish this instead.
Based on replace_buffer(), it uses extract_buffer() to throw away the
marked un-spell-checked text, and then uses read_file() to insert the
spell-checked text at the position where the mark was.
Accordingly, remove unneeded partitioning and related stuff from
do_alt_speller(). Besides pasting the file into the buffer at
current[current_x], ingraft_buffer() also deals with renumbering,
updating totsize, and handling a magicline, so do_alt_speller()
doesn't need to do those anymore.
Move buffer handling and '\r' stripping from read_line() to read_file(),
so that the file gets its format determined and gets stored in its own
buffer entirely in one function. Then use ingraft_buffer() to insert
this new buffer into the current one.
In addition to pasting the file at current[current_x], ingraft_buffer()
also deals with renumbering, the updating of totsize, and the handling
of a magicline, so read_file() doesn't need to do those anymore.
Note that all this makes read_file() depend on the position of
current[current_x] to know where to insert the file. Accordingly,
set current_x to zero in initialize_buffer_text() instead of in
make_new_buffer(), so that replace_buffer() keeps working properly.
Add its explanation as a separate paragraph.
Also: improve the argument of the --syntax option, as this is a <name>
and not merely a bundle of characters like the other <str> arguments.
In this last loop of break_line(), the pointer 'line' is one step ahead
of the index 'lastblank'. So the loop should first add the length of
the preceding character to 'lastblank' before determining the length
of the current character (and using this to advance 'line').
(There is something wrong in the last loop: line is one character ahead
of lastblank, but the current character length is added to both of them.
It thus assumes that all blank characters are the same number of bytes.
For spaces and tabs this works fine. But for more exotic blanks...)
Also, rename a parameter to be less cryptic, and remove an entire

Instead of allocating enough space to convert the entire passed string,
just allocate space for converting the part that will be converted --

The previous code only directly refreshed the screen when the margin
changed due to toggling line numbering on. When the margin changed
due to toggling it off, it would indirectly refresh via do_toggle().
When replacements are made, nothing needs to be reset any more
(it was done insufficiently anyway). Just make sure the screen
is refreshed when all is done -- this may be superfluous when
doing interactive replacements, but not when replacing all.
When coloring a line, look only at the multidata of the preceding
line, and based on that determine what to seek in the current line.
This fixes https://savannah.gnu.org/bugs/?50292.
When painting a line, the multidata of the line /before/ it is valid
in most cases: it was determined just a moment ago. And it tells us
all we need to know: whether there is an unpaired start match before
the current line or not.
The only exception is when painting the first line of the screen:
the multidata of the line before it might be stale. So for the
first screen line we will always have to do some backtracking.
But that is left for later.
This fixes https://savannah.gnu.org/bugs/?50121.
If we're somewhere deep into the file and do a spell check, and the
first misspelled word happens to be right there, onscreen already,
then this word does not need to be centered -- it /should/ not be
centered. We should scroll only when necessary.
After the changes to the search routine, it is no longer necessary to
take one step back before starting a replacement session.
This fixes https://savannah.gnu.org/bugs/?50147.
Even when a match falls within the marked region, this does not mean
that it is a true match when already the whole file has been searched,
because then this is the second time we find this match.
This fixes https://savannah.gnu.org/bugs/?50158.
The spell fixer does not provide a beginning line, so the search routine
should then not try to refer to any data of this line. Also, since the
changes to the search routine there is no need any more to retreat one
step before starting to search for a misspelled word.
This fixes https://savannah.gnu.org/bugs/?50159.
That is: remove the special treatment of BOW anchors, and instead make
regexes match against the whole line instead of against an artificially
shortened one, because the latter method creates ghost matches: matches

When the tail of a match falls outside of the marked region,
it is in fact not a match and should not be replaced.

When a replacement happens right at where the cursor sits, the position
of the cursor should not be adjusted, because the real cursor position
is between the current character and the preceding one: the place where
the cursor is shown is in fact right /after/ the insertion point.

Just assign the 'CNONE' value upfront, instead of figuring out

Also, the old logic would leave unmarked a line that contains a
start match without any terminating end match. Not serious, but
not right.
Don't blithely overshoot the end of a line when both start regex and
end regex match an empty string. Overshooting would let the matching
run on into uncharted country and thus ultimately cause a segfault.

During precalculation and in step_two, we begin looking for an end
match only after the full start match, not merely one byte beyond
its starting point. So do that too when searching backward for an
unpaired start match.
Also, index can never be zero here, because if the match was of length
zero, this piece of code will have been skipped by the preceding goto.
So we can always use REG_NOTBOL here.
(That goto is wrong, by the way: https://savannah.gnu.org/bugs/?50078,
but that will follow later.)
A search should start at the place of the cursor, not one step beyond,
so that the non-word boundary between the current character and the next
will be found. Starting one step beyond the current character, as was
done until now, would find the non-word boundary between the next and
the overnext character as the first one.
If the given line is out of range of editwinrows, we don't display it
at all, so we obviously don't display more than one line of it. Thus,
the return value in this case should be zero, not one.
(The mistake becomes visible when you go to the end of a very long line
of double-width characters: the $ will be shown on the right edge, even
though you're already at line's end.)
This reverts commit 16a7fd4b from yesterday.
When there is no end match after a start, it is pointless to look
for any more starts because also they will not have any end match,
so nothing will get painted -- just cut the loop short.
The tiny version can do regex searches nowadays, so the user might use
the \< and \> anchors in their regexes.
This fixes https://savannah.gnu.org/bugs/?50008.
The renamed variable 'index' is not the start of a match (as some comment
mistakenly said), but from where in the line we start looking for a next
match.
Also, use one more goto to allow unindenting a big piece of code, and
shortcircuit two while loops for two more small unindents.
The setting of current_y in copy_from_filestruct() also appears to be
a holdover from the days of a more-common STATIONARY scrolling mode.
do_cut_text() uses the above function when copying text (uncutting
text again right after cutting it). Since the text is effectively
the same afterward, current_y doesn't need to change.
do_uncut_text(), however, does need current_y up to date in one case:
when uncutting a full screen or less' worth of lines, focusing will be
FALSE, and it uses edit_refresh(), so it will use STATIONARY scrolling
mode then. Take a cue from do_insertfile() and call reset_cursor() to
get an updated current_y.
(Note that the check for a full screen or less' worth of lines uses
incorrect values when in softwrap mode, but that's a separate problem.)
undo_cut(), do_redo(), and backup_lines() do not need set current_y
because they all result in edit_refresh() with focusing = TRUE, so
they do a CENTERING scroll which does not need current_y.
It is the misuse of "x_" to mean a column position on screen, and the
misuse of "_col" to mean a character position in a string that causes
this confusion.
All these different "start"s and "end"s are confusing. Use instead
'from_x and 'till_x' to remember which part of the current line is
visible now on screen and is thus represented in 'converted'.
In order to determine the correct multidata for a line that doesn't
have such data yet, the whole line must be examined, not just the
part that fits within the screen width.
This fixes https://savannah.gnu.org/bugs/?49978.
A tag begins not merely with a "<" but it must be followed by an
ASCII alphabetic character or one of "/", "!" and "?".

If the system on which nano is configured does not have the 'makeinfo'

Instead of setting openfile->current_y (and wrongly so), just call
reset_cursor() to recompute current_y and place the cursor on that
line (if it is not offscreen).
The search routine begins searching right after the cursor and behaves
as if the line starts there, which means that a beginning-of-word anchor
(\< or \b) will match there also when in fact the cursor is sitting in
the middle of a word. To prevent finding a false match, verify that
for a regex that starts with a BOW anchor the found match is actually
the start of a word.
This fixes https://savannah.gnu.org/bugs/?45630.
Since do_mouse() uses edit_redraw(), openfile->current_y will be
immediately recalculated, so there's no point in changing it now.
Use a temporary variable instead.
The value of sameline doesn't change, so it can be initialized to that.
Since i holds openfile->current_y, it should be ssize_t, not size_t.
And it's better to do the most significant part of a calculation first.
Many of the adjustments of the value of openfile->current_y appear to be
a holdover from the days when certain functions had to account for what
is now called STATIONARY scrolling mode, which depends on the value of
current_y. Remove these adjustement where they are superfluous.
do_para_begin(), do_para_end(), and do_bracket_match() update the screen
through edit_redraw(), which uses either CENTERING or FLOWING scrolling
mode, so their setting of current_y is redundant and useless, as it will
be ignored and then overridden by the next call to reset_cursor().
findnextstr() is called by go_looking() [which calls edit_redraw(), see
above], and by do_replace_loop() and do_int_spell_fix(), which both call
edit_refresh(), which in this case only uses CENTERING scrolling mode
since focusing is TRUE.
(Additionally, the adjustments of current_y in findnextstr() and
do_bracket_match() use incorrect values when in softwrap mode.)
find_paragraph() doesn't need to save or restore current_y, because it
doesn't do any screen updates. do_justify() calls edit_refresh() with
focusing set to TRUE, so it uses the CENTERING scrolling mode.
do_alt_speller() and do_formatter() do not need to save and restore
current_y, because they don't modify it in any way.
This addresses https://savannah.gnu.org/patch/?9197.

After a call to the Formatter or the Alternate spell checker, the data

undo stack away, to prevent undoing things wrongly or even crashing.
(Changes made with the internal spell checker can be undone and redone
without a problem -- nano keeps full track of those. But the changes
made with a formatter or an external spell checker happen in another
process, so nano has no record of them.)
This fixes https://savannah.gnu.org/bugs/?49920.
When using an external spell checker or formatter, the line with
the cursor might become shorter, which might result in the stored
cursor position being beyond the end-of-line. So, when restoring

In path names and file names, 0x0A means an embedded newline and

Most full paths are needed only temporarily and will be freed within

That is: elide a second test from the most travelled path: a valid
character. This adds a second call of mblen() when parse_mbchar()

When wanting to debug something, it is far more useful
to temporarily insert lines like:
statusline(ALERT, "name = %i", variable);
It provides instant feedback, and it slows things down,
so you can kind of see what happens.
The functions read() and fwrite() take size_t, not ssize_t.
And line numbers in the file should be displayed as a long type instead
of an int, since the effective type of ssize_t is not int, but long.
(The variable 'pletion_line' is not conditionalized with this option, as
it would become messy. The compiler will probably be able to elide it.)
When using --enable-tiny, it is not possible to use --enable-wordcomp,
because the word completion function uses the undo system.
Executing the 'complete_a_word' function will search from the start
of the current buffer for entire words that begin with the fragment
that is before the cursor, and will complete this fragment to the
first word that is found. Each consecutive call of 'complete_a_word'
will search for the next matching word and will complete the fragment
to that. By default the function is bound to the ^] keystroke.

Returning a zero would mean returning a ^Space -- the keycode that
by default is bound to the Next-Word function. So, unbinding the
keys to which the modified Arrow keys are hard bound would cause
the latter ones to mysteriously jump to the next word.
This partially fixes https://savannah.gnu.org/bugs/?49058.
Add the keycodes and routines to allow the user to forego setting the
mark explicitly (with M-A / ^6) and instead quickly select a few words
or lines by holding down Shift together with the movement keys.
(Some combinations with Shift are swallowed by some terminal emulators.
To work around some of those, the combinations Shift+Alt+Left/Right work
as Shift+Home/End and Shift+Alt+Up/Down work as Shift+PageUp/PageDown.)
This also prevents the message from spilling into the help lines
when the terminal is less than four columns wide. (Not that one
can read anything then, but it looks better.)
Even when the edit window consists of just one or two lines, the PageUp
and PageDown functions (^Y and ^V) should continue to move the window.

When using the default speller or the formatter, the placewewant is

It is quicker to do a handful of superfluous compares at the end of
each line than it is to compute and keep track of and compare the
remaining line length the whole time.
The typical line is some sixty characters long, the typical search
string ten characters -- with a shorter search string the speedup is
even higher: some fifteen percent. Only when the string is longer
than half the average line length does searching become slower with
this new method.
All this for a UTF-8 locale. For a C locale it makes no difference.
Now that mbstrncasecmp() does the right thing, there is no need any
more to verify that only a valid multibyte sequence was matched.
(See https://savannah.gnu.org/bugs/?45579 for a test case.)
Also, this will make it possible to search for invalid sequences.
(Currently it isn't possible to enter a search string with invalid
characters, but... a user might edit the search history file. And
if pasting at the prompt is implemented, it will be trivial to enter
invalid sequences if you have a file that contains them.)
Persisting might lead to count 'n' reaching zero, which would mean that
the needle has matched, which is wrong when one of the strings contains
an invalid or incomplete multibyte sequence.
That is: don't run towlower() on the two differing bytes when having
reached the end of one of the strings.
This fixes https://savannah.gnu.org/bugs/?48700.
In the bargain, don't do the conversion to lowercase twice.
Furthermore, persist when encountering invalid byte sequences --
until finding bytes that differ.
The needle is never part of the hay -- it is always a separate string.
(And even if needle and haystack were identical, the routine works fine,
the case does not need special treatment.)
When doing an <Up> on the top line, or a <Down> on the bottom line of
the edit window, the affected lines have already been redrawn by the
scrolling code, so there is no need to do that again.
(However, that does not prevent the second line (or the last-but-one
line) from being redrawn unnecessarily when using the M-- (or M-+)
command elsewhere on the screen and /that/ line is horizontally
scrolled. But we'll let that pass for now.)
For horizontal scrolling, it is not the /desired/ column position that
is relevant for determining whether a line needs to be redrawn after a
cursor movement, but the /actual/ column positions before and after.

When we get a ^J as verbatim input, it is not possible to include it

in verbatim input. But the choice has been made to act the same way
as when the ^J (0x0A) is found in the file data: start a new line.
That is the same response as to the Enter key, yes -- but the code
for the Enter key is ^M (0x0D), not ^J. So, to be more precise,
rename the relevant variable from 'got_enter' to 'got_newline'.

Invalid multibyte sequences get depicted with the Replacement Character,
and unassigned codepoints are shown as if they were a space. Both have
a width of one.
Just allocate ample space up front and thus discard the delaying 'if' for
each and every character. In most cases this will allocate far too much,
but that hardly matters: it is freed again as soon as the line is printed.
Keystrokes are single integers (aided by the flags meta_key and
func_key) but in the input stream they can be encoded as escape
sequences (a series of bytes). Characters are values in byte
range, but in UTF-8 one character can consist of multiple bytes.
Also rename two variables, because the secondary input buffer
that they refer to contains only characters (mostly just one),

Don't make it the responsibility of the executed functions to restore
the list of shortcuts of the edit window. Just detect whether another

The way to update nano.pot is to run 'make nano.pot-update' in the po
subdir. Updating a specific PO file is then done with 'make xx.po'.
(The script mistakenly included all leading comments, not just the
ones marked with "TRANSLATORS:".)
It sounded like an instigation to upgrade, or like a list of
instructions on how to upgrade. But it is merely a list of
noteworthy changes -- what other packages put in the NEWS file.
To add a character, one does not need to allocate twice its size.
And the amount to be moved does not depend on the size of the new
character; it just needs to include the terminating zero.
(This fixes in do_output() the same logical mistakes that were fixed
in do_statusbar_output() last February, in acf19bd and 7c0e433.)
Specifying an operating directory should either lead to a successfull

By moving the test for the only situation where do_comment() does nothing

can be called before the commenting/uncommenting starts and two variables
and an extra function are made unnecessary.
That is: don't mix the number of lines read with a warning about the
file being unwritable -- the former is just convenience information,
the latter is a must-see.

When running in a non-UTF locale, and when strncasecmp() suffers from
the same defect as strncmp(), make sure not to pass a length with the
high bit set.
This reverts commit df8c3de from six years ago, which prevented a crash
on the Armel/Maemo platforms but causes nano to lose history items.
The strncmp() function on those platforms treats size_t numbers with
the high bit set as if they were zero. To avoid that, use a number
that cannot be seen as negative, as suggested by <alpha@qzx.com>.

When opening a file that was edited before, and the remembered position
is near the end of the file, then don't center the target line but show
the last line of the file on the bottom line of the screen, thus showing
as much of the file content as possible.
This addresses https://savannah.gnu.org/bugs/?46243.
Instead of parsing every multibyte character twice, first with
parse_mbchar() and then with mbtowc(), just let mbtowc() do all
the work. This makes searching for a fixed string twice as fast.
This also gets rid of four variables and lots of memory allocations.
(And, more importantly: it stops nano messing up the internal state
of the multibyte-to-wide character conversion, and thus would make
the calls to mbtowc_reset() superfluous.)
This allows for commenting or uncommenting a line or a bunch of lines
with a single keystroke (default binding: M-3). The characters used
for commenting/uncommenting are specified by the active syntax file.

If during startup there are multiple error messages, currently only the
last one remains and can be read. To improve on that, introduce a short

This also causes a few error messages to beep that currently don't beep,

When doing a PageUp or PageDown in the browser, don't move the highlight
to the first line in the same column, but keep it in the same relative
position of the screen. If we're already on the first or last page,
move the highlight to the first or last line, but keep it in the same
column. If we're already on the first or last line, only then move it
to the first or last entry.
CONST_UPDATE is only relevant when in the main menu, not when in the
browser. So, check for that condition, instead of saving, changing,
and then restoring the setting.
There is no need to iterate through all the file names, as we already
know the length of the longest. From this it's easy to calculate how
many names fit on a line.
Also rename some things to be more fitting. And make sure that something
will be selected even when many files, including the selected one, have
disappeared.
When refreshing the screen (and thus the file list), use the prev_dir
mechanism to reselect the file that was selected before the refresh,
to prevent the selection from changing when files were added or deleted.
Also, when the selected name has disappeared, move the highlight one step
back, so that it is obvious that the selection has changed. (Decrementing
'selected' will never make it negative, because selected == 0 means the
'..' entry, and every directory has a '..' entry, so it will be found.)

When fixing a misspelling and not answering 'All' (but 'Yes' or 'No'),
the chance is quite substantial that one will type y or n at the end of

Partitioning the file makes the undo system lose track, so that undoing
things has a good chance of losing data. Instead, just make sure that
the region is marked "backwards", with current at the top and the mark
at the bottom, and then let the replace loop take care of not going
outside of the marked region.
This also has the effect that if the marked region fits entirely on the
screen, or all the misspellings are onscreen, then the screen will not
be scrolled at all. Which makes for a smooth experience.

Since nano-2.4.1, reading in or pasting a large piece of text would put
the cursor on the bottom line, leaving only one line of the non-read or
non-pasted text visible. This is different from the centering behavior
of Pico, and somewhat disorienting, as you can't see "where you are" any
more in relation to the file as it was.
So now center the cursor whenever the read or pasted text is larger than
the screen, but don't center it when the text fits entirely on the screen.
(The latter avoids the effect of the screen jumping unnecessarily when
inserting just a few lines while the cursor is near the bottom.)
To achieve this behavior: default to focusing, and temporarily set it to
FALSE when the focusing effect is unwanted.
This fixes https://savannah.gnu.org/bugs/?47841.
For some reason the keyboard code seems to assume that all integers
waiting in the keybuffer form a single sequence. But this isn't the

an escape after a non-escape as part of the current sequence.

we have come full circle: reaching the end-of-buffer means we're done.

The internal spell checker starts searching/replacing always at the top
of the buffer, so reaching the end of the buffer means we're done with
the current search/replace. This prevents the "Search Wrapped" message
from flashing over the statusbar at the end of a spelling replacement.
Commit 8704dde mistakenly removed this part of code -- it is not dead,
it is just that it will only fire when the user answered No at some of
the replacement prompts. So... when we've rereached the starting line,
a found occurrence is invalid when it is beyond the starting x (either
after or before it, dependending on the direction of search).

For a little contrast with the function edit_refresh() -- it's
annoying that when you search for the latter you get to see all
the settings of the flag too.
The function edit_update() is called by edit_refresh() itself, so it is
silly that the first sets 'edit_refresh_needed' to TRUE. This setting
is needed only in a few cases -- in the others it's not needed because
the screen does not need to be refreshed (it was just about positioning
the cursor), or 'edit_refresh_needed' has already been set by a call to
goto_line_posx(). So, just set the flag in the five places that need it
and spare the other four calls.
Since commit 41ed690, cancelling a prompt after tabbing would sometimes
leave the list of file names on the screen. When testing this first,
it worked fine -- I was fooled again by 'edit_refresh_needed' already
being TRUE when nano has just started up and sits waiting for the first
key stroke. I have to hunt this down and kill it.
Since commit dac0aa1, nano would leave edittop at current after reading
data from standard input, meaning that everything that had been read in
was invisible, "scrolled off" the top of the screen. Correct this by
explicitly setting edittop.
The above does not happen for ^R (^X) because it has a special mechanism
to save and restore edittop. Nor does it happen for ^R ^X M-F because it
sets current to the top of the file and refreshing the screen will make
edittop follow, or -- in case just one unterminated line was read in --
edittop will already be equal to current.
A normal lock file is apparently 1024 bytes in size, so the second
attempt at reading bytes from the file would try to read 8192 more
bytes into a buffer that has room for only 7168 left. According to
valgrind, the read() function doesn't like that -- and true: if for
some reason the lock file had suddenly expanded, the buffer would
overflow.
This fixes https://savannah.gnu.org/bugs/?47156.
Commit 36ec76a made the wrong change: after a tab that did not list any
file names on the screen, a refresh /is/ needed, because a previous tab
might have listed things on the screen. But at the end of the prompt,
it is not necessary to refresh the edit window if things were listed,
because the window will be refreshed anyway after reading in a file.
Use 'slash' to point at a possible slash, use 'filename' just to
point at the real file name, and use 'wasdirname' just to point at
the dir's name before expanding it in order to be able to free it.
Also, remove two superfluous asserts: 'dirname' cannot be NULL
because it has just been mallocstrcpy'd, and checking 'num_matches'
is pointless as it would crash on the next statement anyway.
This is a remnant from 2001, when things were different. Now, there
is no need to refresh the edit window when tabbing produced no list.
When it did produce a list, it is cleared off later.
If for some reason opening the spell-checked or formatted file fails,
don't throw away the current contents of the buffer.
(It should also give proper feedback about the failure, but we'll leave
that for some other time.)
Also, store the input character earlier, so we don't have to use len - 1.
Furthermore, len increments in steps of 1, so it cannot pass the value of
bufx unnoticed, so use a comparison for equality.
Most of the time NO_CONVERT will not be set, the number of lines will
not be zero, and the format of the file will be zero. Rearrange the
conditions so that they will evaluate as FALSE as soon as possible.
Index i follows almost synchronously the value of len. Since we're
adding characters to the intermediate buffer always only at the end,
just use len as the index.
Until now (when not leaving files unconverted), nano would fumble and
drop the final carriage return of a Mac file, and would thus treat the
last line of such a file as an unterminated line and prepend it to the
current line of the buffer. Correct that, and delete the dead piece
of code that was meant to do this.
This fixes https://savannah.gnu.org/bugs/?47716.
When we don't set edittop in read_line(), we don't need to readjust it in
read_file(), because in that particular case it will still be pointing at
current. And since fileptr is a new, freshly created line, it can never
be equal to filebot, so there is no point in comparing them.
If more than one line was inserted at the beginning of the file, leave it
up to the screen handling to set edittop to what it should be.
Move the setting of fileage a bit down, to its sister setting: the line
at current gets "connected" either to the top-of-file pointer or to the
last line of the inserted file.
The number of lines to scroll is: the y position of the start of the
current line, plus the extra lines that this line occupies, plus the
extra lines that the next line occupies, plus one, minus the y position
of the last window line.
The y position of the start of the current line is current_y -
xplustabs() / COLS, the extra lines are strlenpt(data) / COLS,
and the y position of the last window line is editwinrows - 1.
Note that we first compute the amount to scroll before actually moving
to the next line, because we need the current value of current_x, not
the one that it will have in the next line. The placewewant value is
not good either, because it might be beyond where we actually are.
This fixes https://savannah.gnu.org/bugs/?47665.
Doing a chdir("..") will not fail when the root directory is reached,
and when getcwd() keeps failing too, we have no way of knowing when
to stop. So, simply limit the number of attempted chdirs, to avoid

Also, don't force a full refresh of the edit window simply because the
current line needs to be horizontally scrolled. And further, when the
adjustment of edittop has determined that a full refresh is needed,
get out and don't bother scrolling some lines first.
When in softwrap mode and scrolling down a line, and thus going to
do a full refresh, get out and don't bother redrawing the current
and prior lines first.
When moving the cursor up or down one line, redraw the new current
line only when the target column (placewewant) is beyond the screen,
or when the mark is on.
(This still redraws the current and prior lines unnecessarily when
they are in fact shorter than the screen is wide and the mark is off,
but we'll let that pass for now.)
Also, when softwrap is on, we don't have have to redraw the current
and prior lines at all (when the mark is off): they are in full view,
there is nothing to show or hide.
When scrolling down a line, a full refresh of the edit window is only
needed when softwrap is on, because only then the movement is irregular.
When each file line takes up just one screen line (softwrap is off),
edit_scroll() is perfectly able to scroll and redraw only the necessary
lines.
(But... when doing a full refresh anyway with softwrap, why bother
scrolling at all? Why not just adjust edittop and call refresh?)
The old_current line needs to be redrawn only if it differs from current,
and if it wasn't drawn already by the iteration for when the mark is on.
Also make the conditions involving horizontal scrolling more precise.
Instead of saving the current value of placewewant, then setting the
new value, and then passing the old value to edit_redraw() in seven
different places, just let edit_redraw() do this saving and setting.
In the bargain placewewant is now only recalculated when it matters
-- when allow_update is TRUE -- and not when it's superfluous.
Nano doesn't start doing anything with the edit window or the keyboard
until all files have been read in or a blank buffer has been opened, so
the case of openfile->current == NULL will never occur.
Also correct the comment -- because with multibyte characters, it is
very well possible that the screen column corresponding to current_x
is smaller than current_x itself.
Instead of allocating a fixed amount of 128 bytes, which will overflow
and segfault, adjust the allocation to the length of the file name, and
if necessary trim the file name to make the prompt fit on the screen.

In the innermost search loop, don't set placewewant, because this loop
is also used for replacing and spell fixing, when we don't really want
to be there: we are just passing through. Not setting placewewant means
we don't need to save and restore it in those passing-through routines.
The value of placewewant is only relevant when doing cursor movement,
which doesn't happen during replacing nor spell checking, so there is
no need to keep placewewant up to date -- it is set when it matters:
at the end of go_looking().
Stop keeping track of the vertical screen position when searching for
something. If nothing is found, current_y doesn't change, and all the
incrementing/decrementing was a waste of time. If something is found
and it is onscreen, it is easy to calculate the new current_y. And if
something is found and it is offscreen, then current_y is irrelevant,
because we will be either centering the found occurrence (searching)
or putting it on the top or bottom line (bracket matching).
(The above does not take softwrapping into account, but neither did
the old code, so this doesn't introduce any new bugs.)
(Also, when the search wraps, and the viewport is away from head or
tail of the file, and the found occurrence is within the viewport,
then the incremented/decremented current_y would be way wrong, but
this didn't have any adverse effects as far as I could tell. It
seems that current_y is irrelevant in most cases.)
Add a third mode of scrolling, FLOWING, besides CENTERING and STATIONARY.
This is used for word and paragraph jumping (and for bracket matching,
but that worked correctly already), and only when focusing is FALSE.
The new mode prevents the screen from scrolling too many lines when
there are several blank lines at the bottom of the edit window and
the next word or paragraph is out of view.

our files, and doesn't yet support setting the file as modified; just lets a
vim user know we're editing a file. Commands line "-G" or "--locking", nanorc
option "locking". New functions src/files.c:do_lockfile(), write_lockfile(),
and delete_lockfile().

(slmatcharray, pbegin, paintok), new logic (with repeated setting od values in the
array but its BFI after all). FIXME: Need to create a new 'overlap'
* src/*: Fix a silly issue with the argument to nregcomp, as it's confusing to the caller
* src/nano.h: Change the color types to a compiler macro (COLORWIDTH), may not actually
even be worth doing, but someday who knows how wide a color curses implementation might
be, and maybe we'll even start checking for it in autoconf!

This does add 20KB to nano's executable size but it gets rid of a lot of indirection
that makes people stomach turn. There are several new stub functions and need of more
tidying as a result of this.
git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@4527 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

of knowing about it in that case. Fixes Savannah bug 29392, reported
by Mike Frysinger.

It aimed to "emulate Pico as closely as is reasonable and then include extra functionality".</p></blockquote>
<h3><aname="1.2"></a>1.2. What is the history behind nano?</h3>
<blockquote><p>Funny you should ask!</p>
<p><b>In the beginning...</b></p>
<p>For years Pine was THE program used to read email on a Unix system. The Pico text editor is the portion of the program one would use to compose his or her mail messages. Many beginners to Unix flocked to Pico and Pine because of their well organized, easy to use interfaces. With the proliferation of GNU/Linux in the mid to late 90's, many University students became intimately familiar with the strengths (and weaknesses) of Pine and Pico.</p>
<p><b>Then came Debian...</b></p>
<p>The <ahref="http://www.debian.org/">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly "free" software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but the versions available at the time were not truly free software in the <ahref="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>

Many people had a serious dilemma: they loved these programs, but the versions available at the time were not truly free software in the <ahref="https://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>
<p><b>The event...</b></p>
<p>It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.</p>
<p>Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help text display, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is today.</p>

<p>In February 2001, nano was declared an official GNU program by Richard Stallman. nano also reached its first production release on March 22, 2001.</p></blockquote>
<h2><aname="1.5"></a>1.5. Why the name change from TIP?</h2>
<h3><aname="1.3"></a>1.3. Why the name change from TIP?</h3>
<blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program "establishes a full duplex terminal connection to a remote host", and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>
<h2><aname="1.6"></a>1.6. What is the current version of nano?</h2>

<blockquote><p>It was decided that consistency was nice, but people are used to Pico's inconsistent behavior. Also, in version 1.1.99pre1, search and replace history was introduced. If you wish to edit your previous search/replace entry (or any previous entry), you can do so by hitting the up arrow to cycle through your history. This method allows the best of both worlds: You don't need to erase the previous string if you want to enter a new one, but you can with one keystroke recall previous entries for editing. Therefore there is now no "Pico mode", nano is and has always been a Pico <b>clone</b>, and clones by default should be compatible.</p></blockquote>

<h1><aname="5"></a>5. Internationalization</h1>
<h2><aname="5.1"></a>5.1. There's no translation for my language!</h2>
<blockquote><p>On June of 2001, GNU nano entered the <ahref="http://translationproject.org/html/welcome.html">Free Translation Project</a> and since then, translations should be managed from there.</p>
<p>If there isn't a translation for your language, you could ask <ahref="http://translationproject.org/team/">your language team</a> to translate nano, or better still, join your team and do it yourself. Joining a team is easy. You just need to ask the <ahref="mailto:coordinator@translationproject.org">TP coordinator</a> to add you to your team, and send a <ahref="http://translationproject.org/disclaim.txt">translation disclaimer to the FSF</a> (this is necessary as nano is an official GNU package, but it does <b>not</b> mean that you transfer the rights of your work to the FSF, it's just so the FSF can legally manage them).</p>
<p>In any case, translating nano is very easy. Just grab the <b>nano.pot</b> file from the latest and greatest nano distribution (it's in the <b>po/</b>directory) and translate each line into your native language on the <b>msgstr</b> line. When you're done, you should send it to the TP's central po repository.</p></blockquote>
<h2><aname="5.2"></a>5.2. I don't like the translation for <x> in my language. How can I fix it?</h2>
<blockquote><p>The best way would probably be to e-mail the person listed in the <code>Last-Translator:</code> field in the <b><your_language>.po</b> file with your suggested corrections and they can make the changes reach the nano-devel list.</p></blockquote>
<h2><aname="5.3"></a>5.3. What is the status of Unicode support?</h2>
<blockquote><p>In version 1.3.12 or later, Unicode should be usable. With your terminal, locale (LC_ALL and similar environment variables), and encoding configured to properly support UTF-8, you should be able to enter and save Unicode text.</p></blockquote>

<h1><aname="6"></a>6. Advocacy and Licensing</h1>
<h2><aname="6.1"></a>6.1. Why should I use nano instead of Pico?</h2>
<blockquote><p>There are many reasons to use nano instead of Pico. A more complete list can be found at the <ahref="http://www.nano-editor.org/">nano homepage</a>.</p></blockquote>
<h2><aname="6.2"></a>6.2. Why should I use Pico instead of nano?</h2>
<blockquote><p>Again, check out the <ahref="http://www.nano-editor.org/">nano homepage</a> for a good summary of reasons. It really is a matter of personal preference as to which editor you should use. If you're the type of person who likes using the original version of a program, then Pico is the editor for you. If you don't mind sacrificing mailer integration with Pine, and are looking for a few more features, as well as a 'better' license in terms of adding your own changes, nano is the way to go.</p><p>Note that the last of these no longer applies to the new version of Pine, <ahref="http://www.washington.edu/alpine/">Alpine</a>, which is under the Apache License, version 2.0.</p></blockquote>
<h2><aname="6.3"></a>6.3. What is so bad about the older Pine license?</h2>
<blockquote><p>The U of W license for older versions of Pine and Pico is not considered truly Free Software according to both the Free Software Foundation and the <ahref="http://www.debian.org/social_contract#guidelines">Debian Free Software Guidelines</a>. The main problem regards the limitations on distributing derived works: according to UW, you can distribute their software, and you can modify it, but you can not do both, i.e. distribute modified binaries.</p></blockquote>
<h2><aname="6.4"></a>6.4. Okay, well, what mail program should I use then?</h2>
<blockquote><p>If you are looking to use a Free Software program similar to Pine, and Emacs is not your thing, you should definitely take a look at <ahref="http://www.mutt.org/">mutt</a>. It is a full-screen, console based mail program that actually has a lot more flexibility than Pine, but has a keymap included in the distribution that allows you to use the same keystrokes as Pine would to send and receive mail. It's also under the GNU General Public License, version 2.0.<P>
Of course, due to the license change you can now use the <AHREF="http://www.washington.edu/alpine/">Alpine distribution</A> of PINE as it is now considered Free Software, but you would be sacrificing many of nano's features to do so.</p></blockquote>
<h3><aname="6.1"></a>6.1. Why should I use nano instead of Pico?</h3>
<blockquote><p>If you want features like undo/redo, syntax highlighting, line numbers, soft-wrapping, opening multiple files at once, an interface localized to your language, or search and replace with support for regular expressions, then you want nano.</p></blockquote>
<h3><aname="6.2"></a>6.2. Why should I use Pico instead of nano?</h3>
<blockquote><p>If you use your editor only to write emails or other texts and have no need for the above-mentioned features, then Pico will do fine for you.</p></blockquote>
<h3><aname="6.3"></a>6.3. What is so bad about the older Pine license?</h3>

<blockquote><p>There are three mailing lists for nano hosted at <ahref="http://savannah.gnu.org/">Savannah</a>, info-nano, help-nano and nano-devel. info-nano is a very low traffic list where new versions of nano are announced (surprise!). help-nano is for getting help with the editor without needing to hear all of the development issues surrounding it. nano-devel is a normally low, sometimes high traffic list for discussing the present and future development of nano. Here are links to where you can sign up for a given list:</p>
<h2><aname="7.2"></a>7.2. I want to send the development team a big load of cash (or just a thank you).</h2>
<blockquote><p>That's fine. Send it <ahref="mailto:nano-devel@gnu.org">our way</a>!

(DLR)<br>
2004/04/07 - Removed NumLock glitch question, as it's no longer needed. (DLR)<br>
