+Changelog
+==============
+
+kitty is a feature full, cross-platform, *fast*, GPU based terminal emulator.
+
+version 0.6.0 [2017-12-18]
+---------------------------
+
+- Support background transparency via the background_opacity option. Provided
+  that your OS/window manager supports transparency, you can now have kitty
+  render pixels that have only the default background color as
+  semi-transparent.
+
+- Support multiple top level (OS) windows. These windows all share the sprite
+  texture cache on the GPU, further reducing overall resource usage. Use
+  the shortcut `ctrl+shift+n` to open a new top-level window.
+
+- Add support for a *daemon* mode using the `--single-instance` command line
+  option. With this option you can have only a single kitty instance running.
+  All future invocations simply open new top-level windows in the existing
+  instance.
+
+- Support colored emoji
+
+- Use CoreText instead of FreeType to render text on macOS
+
+- Support running on the "low power" GPU on dual GPU macOS machines
+
+- Add a new "grid" window layout
+
+- Drop the dependency on glfw (kitty now uses a modified, bundled copy of glfw)
+
+- Add an option to control the audio bell volume on X11 systems
+
+- Add a command line switch to set the name part of the WM_CLASS window
+  property independently.
+
+- Add a command line switch to set the window title.
+
+- Add more options to customize the tab-bar's appearance (font styles and
+  separator)
+
+- Allow drag and drop of files into kitty. On drop kitty will paste the
+  file path to the running program.
+
+- Add an option to control the underline style for URL highlighting on hover
+
+- X11: Set the WINDOWID environment variable 
+
+- Fix middle and right buttons swapped when sending mouse events to child
+  processes
+
+- Allow selecting in a rectangle by holding down Ctrl+Alt while dragging with
+  the mouse.
+
+
+version 0.5.1 [2017-12-01]
+---------------------------
+
+- Add an option to control the thickness of lines in box drawing characters
+
+- Increase max. allowed ligature length to nine characters
+
+- Fix text not vertically centered when adjusting line height
+
+- Fix unicode block characters not being rendered properly
+
+- Fix shift+up/down not generating correct escape codes
+
+- Image display: Fix displaying images taller than two screen heights not
+  scrolling properly
+
+
+version 0.5.0 [2017-11-19]
+---------------------------
+
+- Add support for ligature fonts such as Fira Code, Hasklig, etc. kitty now
+  uses harfbuzz for text shaping which allow it to support advanced OpenType
+  features such as contextual alternates/ligatures/combining glyphs/etc.
+
+- Make it easy to select fonts by allowing listing of monospace fonts using:
+  kitty list-fonts
+
+- Add an option to have window focus follow mouse
+
+- Add a keyboard shortcut (ctrl+shift+f11) to toggle fullscreen mode
+
+- macOS: Fix handling of option key. It now behaves just like the alt key on
+  Linux. There is an option to make it type unicode characters instead.
+
+- Linux: Add support for startup notification on X11 desktops. kitty will
+  now inform the window manager when its startup is complete.
+
+- Fix shell prompt being duplicated when window is resized
+
+- Fix crash when displaying more than 64 images in the same session
+
+- Add support for colons in SGR color codes. These are generated by some
+  applications such as neovim when they mistakenly identify kitty as a libvte
+  based terminal.
+
+- Fix mouse interaction not working in apps using obsolete mouse interaction
+  protocols
+
+- Linux: no longer require glew as a dependency
+
+
+version 0.4.2 [2017-10-23]
+---------------------------
+
+- Fix a regression in 0.4.0 that broke custom key mappings
+
+- Fix a regression in 0.4.0 that broke support for non-QWERTY keyboard layouts 
+
+- Avoid using threads to reap zombie child processes. Also prevent kitty from
+  hanging if the open program hangs when clicking on a URL.
+
+
+version 0.4.0 [2017-10-22]
+---------------------------
+
+- Support for drawing arbitrary raster graphics (images) in the terminal via a
+  new graphics protocol. kitty can draw images with full 32-bit color using both
+  ssh connections and files/shared memory (when available) for better
+  performance. The drawing primitives support alpha blending and z-index.
+  Images can be drawn both above and below text. See
+  https://github.com/kovidgoyal/kitty/blob/master/graphics-protocol.asciidoc
+  for details. 
+
+- Refactor kitty's internals to make it even faster and more efficient. The CPU
+  usage of kitty + X server while doing intensive tasks such as scrolling a
+  file continuously in less has been reduced by 50%. There are now two
+  configuration options ``repaint_delay`` and ``input_delay`` you can use to
+  fine tune kitty's performance vs CPU usage profile. The CPU usage of kitty +
+  X when scrolling in less is now significantly better than most (all?) other
+  terminals. See https://github.com/kovidgoyal/kitty#performance
+
+- Hovering over URLs with the mouse now underlines them to indicate they
+  can be clicked. Hold down Ctrl+Shift while clicking to open the URL.
+
+- Selection using the mouse is now more intelligent. It does not add
+  blank cells (i.e. cells that have no content) after the end of text in a
+  line to the selection.
+
+- The block cursor in now fully opaque but renders the character under it in
+  the background color, for enhanced visibility.
+
+- Allow combining multiple independent actions into a single shortcut
+
+- Add a new shortcut to pass the current selection to an external program
+
+- Allow creating shortcuts to open new windows running arbitrary commands. You
+  can also pass the current selection to the command as an arguments and the
+  contents of the screen + scrollback buffer as stdin to the command.

+== Performance
+
+The main goals for kitty performance are user perceived latency while typing
+and "smoothness" while scrolling as well as CPU usage. kitty tries hard to find
+an optimum balance for these. To that end it keeps a cache of each rendered
+glyph in video RAM so that font rendering is not a bottleneck.  Interaction
+with child programs takes place in a separate thread from rendering, to improve
+smoothness.
+
+There are two parameters you can tune to adjust the performance. ``repaint_delay``
+and ``input_delay``. These control the artificial delays introduced into the
+render loop to reduce CPU usage. See the link:kitty/kitty.conf[config file] for details.
+
+You can generate detailed per-function performance data using
+link:https://github.com/gperftools/gperftools[gperftools]. Build kitty with the
+`--profile` flag which will create an executable called `kitty-profile`.  Run
+that and perform the task you want to analyse, for example, scrolling a large 
+file with `less`. After you quit, function call statistics will be printed to
+`stdout` and you can use tools like *kcachegrind* for more detailed analysis.
+
+Here are some CPU usage numbers for the task of scrolling a file continuously in less.
+The CPU usage is for the terminal process and X together and is measured using htop.
+The measurements are taken at the same font and window size for all terminals on a 
+`Intel(R) Core(TM) i7-4820K CPU @ 3.70GHz` CPU with a 
+`Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde XT [Radeon HD 7770/8760 / R7 250X]` GPU.
+
+|===
+| Terminal | CPU usage (X + terminal)
+
+| kitty    | 6 - 8%
+| xterm    | 5 - 7% (but scrolling was extremely janky)
+| termite  | 10 - 13%
+| urxvt    | 12 - 14%
+| gnome-terminal | 15 - 17%
+| konsole  | 29 - 31%
+
+|===
+
+As you can see, kitty uses much less CPU than all terminals, except xterm, but
+its scrolling "smoothness" is much better than that of xterm (at least to my,
+admittedly biased, eyes).

+
+== Frequently Asked Questions
+
+=== Some special symbols are rendered small/truncated in kitty?
+
+The number of cells a unicode character takes up are controlled by the
+`wcwidth()` system function. If wcwidth() returns 2 then kitty will render the
+character in two cells, otherwise it will render it in one cell. Often the
+system `wcwidth()` is old/outdated. You can use the `use_system_wcwidth=no`
+setting in your kitty.conf to workaround this. But note that it might cause
+other issues, since now kitty and the programs running inside it may not agree
+on how wide characters should be. When a symbol does not fit, it will either be
+rescaled to be smaller or truncated (depending on how much extra space it
+needs). This is often different from other terminals which just let the
+character overflow into neighboring cells, leading to ugly artifacts.
+
+In addition to the problem with `wcwidth()` above, some programs, like
+powerline, vim with fancy gutter symbols/status-bar, etc. use unicode
+characters from the private use area to represent symbols. Often these symbols
+are square and should be rendered in two cells.  However, since private use
+area symbols all have `wcwdith() == 1` kitty renders them either smaller or
+truncated. The correct solution for this is to use either use different symbols
+that are not square, or to use a font that defines ligatures with the space
+character for these symbols. See
+link:https://github.com/kovidgoyal/kitty/issues/182[#182] for a discussion of
+the approach using ligatures.
+
+=== How do I build kitty.app on macOS?

+You dont need to build kitty.app to run kitty from source. Simply install the dependencies
+listed above using brew/MacPorts or similar and then compile and run with:
+
+```
+make 
+python3 .
+```
+
+You can also create a shell script to run kitty:
+
+```
+#!/bin/sh
+exec python3 /path/to/kitty/source/dir
+```
+
+And using something like link:https://mathiasbynens.be/notes/shell-script-mac-apps[app-wrapper-for-shell-script]
+you can create a simple launcher app to run the shell script.
+
+If you only want to make some small changes to a python file, you can do that
+and simply replace the corresponding file inside an existing kitty.app. (Note
+that kitty.app will contain `.pyo` files which are compiled versions of `.py`
+files, delete the `.pyo` file and replace it with a `.py` file).
+
+Finally, note that the released kitty.dmg is built automatically by using the
+`kitty` branch of
+link:https://github.com/kovidgoyal/build-calibre[build-calibre] however, that
+is designed to run on linux and is not for the faint of heart.

+/*
+ * This module converts keysym values into the corresponding ISO 10646
+ * (UCS, Unicode) values.
+ *
+ * The array keysymtab[] contains pairs of X11 keysym values for graphical
+ * characters and the corresponding Unicode value. The function
+ * _glfwKeySym2Unicode() maps a keysym onto a Unicode value using a binary
+ * search, therefore keysymtab[] must remain SORTED by keysym value.
+ *
+ * We allow to represent any UCS character in the range U-00000000 to
+ * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
+ * This admittedly does not cover the entire 31-bit space of UCS, but
+ * it does cover all of the characters up to U-10FFFF, which can be
+ * represented by UTF-16, and more, and it is very unlikely that higher
+ * UCS codes will ever be assigned by ISO. So to get Unicode character
+ * U+ABCD you can directly use keysym 0x0100abcd.
+ *

+= The terminal graphics protocol
+:toc:
+:toc-placement!:
+
+The goal of this specification is to create a flexible and performant protocol
+that allows the program running in the terminal, hereafter called the _client_,
+to render arbitrary pixel (raster) graphics to the screen of the terminal
+emulator. The major design goals are
+
+ * Should not require terminal emulators to understand image formats.
+ * Should allow specifying graphics to be drawn at individual pixel positions. 
+ * The graphics should integrate with the text, in particular it should be possible to draw graphics
+   below as well as above the text, with alpha blending. The graphics should also scroll with the text, automatically.
+ * Should use optimizations when the client is running on the same computer as the terminal emulator.
+
+For some discussion regarding the design choices, see link:../../issues/33[#33].
+
+To see a quick demo, inside a kitty terminal run:
+
+```
+kitty icat path/to/some/image.png
+```
+
+You can also see a screenshot with more sophisticated features such as alpha-blending and text over graphics 
+link:https://github.com/kovidgoyal/kitty/issues/33#issuecomment-334436100[here].
+
+toc::[]
+
+== Getting the window size
+
+In order to know what size of images to display and how to position them, the client must be able to get the
+window size in pixels and the number of cells per row and column. This can be done by using the `TIOCGWINSZ` ioctl.
+Some C code to demonstrate its use
+
+```C
+struct ttysize ts; 
+ioctl(0, TIOCGWINSZ, &ts);
+printf("number of columns: %i, number of rows: %i, screen width: %i, screen height: %i\n", sz.ws_col, sz.ws_row, sz.ws_xpixel, sz.ws_ypixel);
+```
+
+Note that some terminals return `0` for the width and height values. Such terminals should be modified to return the correct values.
+Examples of terminals that return correct values: `kitty, xterm`
+
+== The graphics escape code
+
+All graphics escape codes are of the form:
+
+```
+<ESC>_G<control data>;<payload><ESC>\
+```
+
+This is a so-called _Application Programming Command (APC)_. Most terminal
+emulators ignore APC codes, making it safe to use.  
+
+The control data is a comma-separated list of `key=value` pairs.  The payload
+is arbitrary binary data, base64-encoded to prevent interoperation problems
+with legacy terminals that get confused by control codes within an APC code.
+The meaning of the payload is interpreted based on the control data.
+
+The first step is to transmit the actual image data.
+
+== Transferring pixel data
+
+The first consideration when transferring data between the client and the
+terminal emulator is the format in which to do so. Since there is a vast and
+growing number of image formats in existence, it does not make sense to have
+every terminal emulator implement support for them. Instead, the client should
+send simple pixel data to the terminal emulator. The obvious downside to this
+is performance, especially when the client is running on a remote machine.
+Techniques for remedying this limitation are discussed later. The terminal
+emulator must understand pixel data in three formats, 24-bit RGB, 32-bit RGBA and
+PNG. This is specified using the `f` key in the control data. `f=32` (which is the
+default) indicates 32-bit RGBA data and `f=24` indicates 24-bit RGB data and `f=100`
+indicates PNG data. The PNG format is supported for convenience and a compact way
+of transmitting paletted images.
+
+=== RGB and RGBA data
+
+In these formats the pixel data is stored directly as 3 or 4 bytes per pixel, respectively.
+When specifying images in this format, the image dimensions **must** be sent in the control data.
+For example:
+
+```
+<ESC>_Gf=24,s=10,v=20;<payload><ESC>\
+```
+
+Here the width and height are specified using the `s` and `v` keys respectively. Since
+`f=24` there are three bytes per pixel and therefore the pixel data must be `3 * 10 * 20 = 600`
+bytes.
+
+=== PNG data
+
+In this format any PNG image can be transmitted directly.  For example:
+
+```
+<ESC>_Gf=100;<payload><ESC>\
+
+```
+
+The PNG format is specified using the `f=100` key. The width and height of
+the image will be read from the PNG data itself. Note that if you use both PNG and
+compression, then you must provide the `S` key with the size of the PNG data.
+
+
+=== Compression
+
+The client can send compressed image data to the terminal emulator, by specifying the
+`o` key. Currently, only zlib based deflate compression is supported, which is specified using
+`o=z`. For example,
+
+```
+<ESC>_Gf=24,s=10,v=20,o=z;<payload><ESC>\
+```
+
+This is the same as the example from the RGB data section, except that the
+payload is now compressed using deflate. The terminal emulator will decompress
+it before rendering. You can specify compression for any format. The terminal
+emulator will decompress before interpreting the pixel data.
+
+
+=== The transmission medium
+
+The transmission medium is specified using the `t` key. The `t` key defaults to `d`
+and can take the values:
+
+|===
+| Value of `t` | Meaning 
+
+| d | Direct (the data is transmitted within the escape code itself)
+| f | A simple file
+| t | A temporary file, the terminal emulator will delete the file after reading the pixel data
+| s | A http://man7.org/linux/man-pages/man7/shm_overview.7.html[POSIX shared memory object]. The terminal emulator will delete it after reading the pixel data 
+|===
+
+==== Local client
+
+First let us consider the local client techniques (files and shared memory). Some examples:
+
+```
+<ESC>_Gf=100,t=f;<encoded /path/to/file.png><ESC>\
+```
+
+Here we tell the terminal emulator to read PNG data from the specified file of
+the specified size.
+
+```
+<ESC>_Gs=10,v=2,t=s,o=z;<encoded /some-shared-memory-name><ESC>\
+```
+
+Here we tell the terminal emulator to read compressed image data from
+the specified shared memory object.
+
+The client can also specify a size and offset to tell the terminal emulator
+to only read a part of the specified file. The is done using the `S` and `O`
+keys respectively. For example:
+
+```
+<ESC>_Gs=10,v=2,t=s,S=80,O=10;<encoded /some-shared-memory-name><ESC>\
+```
+
+This tells the terminal emulator to read `80` bytes starting from the offset `10`
+inside the specified shared memory buffer.
+
+
+==== Remote client
+
+Remote clients, those that are unable to use the filesystem/shared memory to
+transmit data, must send the pixel data directly using escape codes. Since
+escape codes are of limited maximum length, the data will need to be chunked up
+for transfer. This is done using the `m` key. The pixel data must first be
+base64 encoded then chunked up into chunks no larger than `4096` bytes. The client
+then sends the graphics escape code as usual, with the addition of an `m` key that
+must have the value `1` for all but the last chunk, where it must be `0`. For example,
+if the data is split into three chunks, the client would send the following
+sequence of escape codes to the terminal emulator:
+
+```
+<ESC>_Gs=100,v=30,m=1;<encoded pixel data first chunk><ESC>\                  
+<ESC>_Gm=1;<encoded pixel data second chunk><ESC>\                  
+<ESC>_Gm=0;<encoded pixel data last chunk><ESC>\                  
+```
+
+Note that only the first escape code needs to have the full set of control
+codes such as width, height, format etc. Subsequent chunks must have
+only the `m` key. The client **must** finish sending all chunks for a single image
+before sending any other graphics related escape codes.
+
+
+=== Detecting available transmission mediums
+
+Since a client has no a-priori knowledge of whether it shares a filesystem/shared memory
+with the terminal emulator, it can send an id with the control data, using the `i` key 
+(which can be an arbitrary positive integer up to 4294967295, it must not be zero).
+If it does so, the terminal emulator will reply after trying to load the image, saying
+whether loading was successful or not. For example:
+
+```
+<ESC>_Gi=31,s=10,v=2,t=s;<encoded /some-shared-memory-name><ESC>\
+```
+
+to which the terminal emulator will reply (after trying to load the data):
+
+```
+<ESC>_Gi=31;error message or OK<ESC>\
+```
+
+Here the `i` value will be the same as was sent by the client in the original
+request.  The message data will be a ASCII encoded string containing only
+printable characters and spaces. The string will be `OK` if reading the pixel
+data succeeded or an error message. 
+
+Sometimes, using an id is not appropriate, for example, if you do not want to
+replace a previously sent image with the same id, or if you are sending a dummy
+image and do not want it stored by the terminal emulator. In that case, you can
+use the *query action*, set `a=q`. Then the terminal emulator will try to load
+the image and respond with either OK or an error, as above, but it will not
+replace an existing image with the same id, nor will it store the image.
+
+
+== Display images on screen
+
+Every transmitted image can be displayed an arbitrary number of times on the
+screen, in different locations, using different parts of the source image, as
+needed. You can either simultaneously transmit and display an image using the
+action `a=T`, or first transmit the image with a id, such as `i=10` and then display
+it with `a=p,i=10` which will display the previously transmitted image at the current
+cursor position. When specifying an image id, the terminal emulator will reply with an
+acknowledgement code, which will be either:
+
+```
+<ESC>_Gi=<id>;OK<ESC>\
+```
+
+when the image referred to by id was found, or
+
+```
+<ESC>_Gi=<id>;ENOENT:<some detailed error msg><ESC>\
+```
+
+when the image with the specified id was not found. This is similar to the
+scheme described above for querying available transmission media, except that
+here we are querying if the image with the specified id is available or needs to
+be re-transmitted.
+
+=== Controlling displayed image layout
+
+The image is rendered at the current cursor position, from the upper left corner of
+the current cell. You can also specify extra `X=3` and `Y=4` pixel offsets to display from 
+a different origin within the cell. Note that the offsets must be smaller that the size of the cell.
+
+By default, the entire image will be displayed (images wider than the available
+width will be truncated on the right edge). You can choose a source rectangle (in pixels)
+as the part of the image to display. This is done with the keys: `x, y, w, h` which specify
+the top-left corner, width and height of the source rectangle.
+
+You can also ask the terminal emulator to display the image in a specified rectangle
+(num of columns / num of lines), using the control codes `c,r`. `c` is the number of columns
+and `r` the number of rows. The image will be scaled (enlarged/shrunk) as needed to fit 
+the specified area. Note that if you specify a start cell offset via the `X,Y` keys, it is not
+added to the number of rows/columns.
+
+Finally, you can specify the image *z-index*, i.e. the vertical stacking order. Images
+placed in the same location with different z-index values will be blended if
+they are semi-transparent. You can specify z-index values using the `z` key.
+Negative z-index values mean that the images will be drawn under the text. This
+allows rendering of text on top of images.
+
+== Deleting images
+
+Images can be deleted by using the delete action `a=d`. If specified without any
+other keys, it will delete all images visible on screen. To delete specific images,
+use the `d` key as described in the table below. Note that each value of d has 
+both a lowercase and an uppercase variant. The lowercase variant only deletes the
+images without necessarily freeing up the stored image data, so that the images can be
+re-displayed without needing to resend the data. The uppercase variants will delete
+the image data as well, provided that the image is not referenced elsewhere, such as in the
+scrollback buffer. The values of the `x` and `y` keys are the same as cursor positions (i.e.
+x=1, y=1 is the top left cell).
+
+|===
+| Value of `d` | Meaning 
+
+| `a` or `A` | Delete all images visible on screen
+| `i` or `I` | Delete all images with the specified id, specified using the `i` key.
+| `c` or `C` | Delete all images that intersect with the current cursor position.
+| `p` or `P` | Delete all images that intersect a specific cell, the cell is specified using the `x` and `y` keys
+| `q` or `Q` | Delete all images that intersect a specific cell having a specific z-index. The cell and z-index is specified using the `x`, `y` and `z` keys.
+| `x` or `X` | Delete all images that intersect the specified column, specified using the `x` key.
+| `y` or `Y` | Delete all images that intersect the specified row, specified using the `y` key.
+| `z` or `Z` | Delete all images that have the specified z-index, specified using the `z` key.
+
+|===
+
+
+Some examples:
+
+```
+<ESC>_Ga=d<ESC>\   # delete all visible images
+<ESC>_Ga=d,i=10<ESC>\   # delete the image with id=10
+<ESC>_Ga=Z,z=-1<ESC>\   # delete the images with z-index -1, also freeing up image data
+<ESC>_Ga=P,x=3,y=4<ESC>\   # delete all images that intersect the cell at (3, 4)
+```
+
+=== Image persistence and storage quotas
+
+In order to avoid *Denial-of-Service* attacks, terminal emulators should have a
+maximum storage quota for image data. It should allow at least a few full
+screen images.  For example the quota in kitty is 320MB per buffer. When adding
+a new image, if the total size exceeds the quota, the terminal emulator should
+delete older images to make space for the new one.
+
+
+== Control data reference
+
+The table below shows all the control data keys as well as what values they can
+take, and the default value they take when missing. All integers are 32-bit. 
+
+[cols="^1,<3,^1,<6"]
+|===
+|Key | Value | Default | Description
+
+| `a` | Single character. `(t, T, q, p, d)` | `t` | The overall action this graphics command is performing.
+
+4+^.^h| Keys for image transmission
+
+| `f` | Positive integer. `(24, 32, 100)`. | `32` | The format in which the image data is sent.
+| `t` | Single character. `(d, f, t, s)`. | `d` | The transmission medium used.
+| `s` | Positive integer. | `0` | The width of the image being sent.

+| `o` | Single character. `only z` | `null` | The type of data compression.
+| `m` | zero or one | `0` | Whether there is more chunked data available.
+
+4+^.^h| Keys for image display

+| `x` | Positive integer | `0` | The left edge (in pixels) of the image area to display
+| `y` | Positive integer | `0` | The top edge (in pixels) of the image area to display

+
+|===
+
+
+== Interaction with other terminal actions
+
+When resetting the terminal, all images that are visible on the screen must be
+cleared.  When switching from the main screen to the alternate screen buffer
+(1049 private mode) all images in the alternate screen must be cleared, just as
+all text is cleared. The clear screen escape code (usually `<ESC>[2J`) should also
+clear all images. This is so that the clear command works.
+
+The other commands to erase text must have no effect on graphics.
+The dedicated delete graphics commands must be used for those.
+
+When scrolling the screen (such as when using index cursor movement commands,
+or scrolling through the history buffer), images must be scrolled along with
+text. When page margins are defined and the index commands are used, only
+images that are entirely within the page area (between the margins) must be
+scrolled. When scrolling them would cause them to extend outside the page area,
+they must be clipped.
