IMPROVEMENTS

@@ -2,6 +2,9 @@ Improvements in GNU nano
 ========================
 
 Since 2.9.0:
+  - Addition of the color name "normal", meaning the default color.
+  - A key can be bound to a string -- any mix of text and commands.
+  - Error messages are shown by default in bright white on red.
   - <Tab> and <Shift+Tab> can be used to indent/unindent a marked region.
   - Can snip trailing whitespace while typing, with 'set trimblanks'.
   - The ability to record and replay a series of keystrokes (a macro).

+2018.03.29 - GNU nano 2.9.5 "Kiša pada" changes the way the Scroll-Up

+             keeping the cursor in the same screen position they now
+             keep the cursor in the same text position (if possible).
+             This version further adds a new color name, "normal",
+             which gives the default foreground or background color,
+             which is useful when you want to undo some overzealous
+             painting by earlier syntax regexes.  Bug fixes include:
+             a segfault when trying to insert a file in restricted
+             mode, the reading in of a new file being "undoable", a
+             slight miswrapping of help texts when --linenumbers was

+             cursor key is pressed without Shift even when the cursor
+             cannot move.  Further, it treats tabs fully the same as

 <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>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 in 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>

+<h3><a name="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 &quot;establishes a full duplex terminal connection to a remote host&quot;, 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>

 <blockquote><p>If you're using the official nano .zip file and have extracted all the files, you should take the file nano.rc and place it somewhere on your Win32 system (for example, if you have write permission to do so, at the top of C:\).  Then you must create an Environment variable called HOME which points to the directory where you put nano.rc.  In Windows XP, you can get to Environment variables by right-clicking "My Computer" either on the desktop or in the Start Menu, and selecting Properties.  This should bring up the System Properties panel.  Then click the Advanced Tab, and there should be a button called Environment Variables.  Click that to bring up the Environment Variables section. Now, under User Variables you should be able to click the New button, and make a new Variables Name called HOME, with the Variable Value of whatever path you copied nano.rc into (just the directory name; don't add nano.rc onto the end).</p>
   <p>We're still working on documentation for enabling syntax highlighting on Win32; please bear with us.</p>
   <p>Note that the nano.rc file must remain Unix-formatted in order for nano to understand it.  In other words, you should probably use only nano to edit its config file.  Other programs like Wordpad and Notepad will convert the file to DOS format when saving, and the latter does not even properly read Unix-formatted files to begin with.</p></blockquote>

 <blockquote><p>In nano 2.3.0, cursor-position history was introduced, and both history files now reside in a .nano subdirectory in your home directory.  A newer nano will move an existing search-history file to this new location so it can continue to be used.  This means that if you then try and use an earlier version of nano, it will be unable to see your current search history.  To fix this, run the following command:</p>
   <p><b>ln -sf ~/.nano/search_history ~/.nano_history</b></p>
   <p>The "migration service" (moving the search-history file to its new location) has been deleted from nano in late 2017, since version 2.9.0.  The search-history and position-history files will now be looked for first in ~/.nano/ and, when not found there, then in ~/.local/share/nano/.</p></blockquote>

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>
