This is a major feature release.
-
Added basic support for the Kitty and iTerm2 graphics protocols. These are enabled automatically when corresponding terminal support is detected, or manually with
-f kittyor-f iterm. -
Implemented an 8-color mode, selectable with
-c 8(@hodefoting). -
Implemented a foreground-only switch,
--fg-only. This produces character art using foreground colors only, and will avoid modifying or resetting the background color. Looks best with non-contiguous symbols (e.g.ascii). -
Added builtins for Japanese kana fullwidth symbols. These can now be used without loading any external fonts (try
-c none --symbols wide). -
Added builtins for legacy computer symbols (mainly wedges and sextant blocks). These were widely used in PETSCII and Teletext, and can be enabled using
--symbolsor--fillwith their respective tags:legacy,wedgeandsextant(@hodefoting). -
Since there is a growing number of builtin symbols that may not be available everywhere, the default selection has been restricted to the widely supported block and border sets.
-
If possible, we now select a visually blank character from the specified symbol/fill sets instead of hardcoding ASCII space for featureless cells. One practical upshot of this is that the constant-width braille range can be used to produce consistent images even in contexts with variable-width fonts. U+2800 (BRAILLE PATTERN BLANK) will then be used in blank cells.
-
Improved terminal size detection when used with pipelines and redirection. This should now produce an image properly sized for your terminal:

ChafaCanvas gained API functions for programmatically getting and setting character cell contents. These are used in a new example in tests/ncurses.c demonstrating ncurses integration.

Made

Added a HACKING file featuring a much needed release checklist.
