This release adds major features and important fixes to both libchafa and the chafa command-line tool.
-
Added support for fullwidth symbols that take up two character cells. These are common in East Asian scripts. Single-cell and double-cell symbols can be mixed, and
-f symbolsmode will use both if possible. -
New symbol tags:
alpha,digit,alnum,narrow,wide,ambiguous,ugly,bad. "Ambiguous" symbols have uncertain widths and may render poorly in some terminals. "Ugly" denotes symbols that are unsuitable for Chafa's cell-based graphics (multicolor emoji, ideographic descriptors, etc). "Bad" is a superset of these two categories. Bad symbols are always excluded unless explicitly enabled with e.g.CHAFA_SYMBOL_TAG_BAD(--symbols +badin the frontend). -
The font loader (
--glyph-fileoption) now does a better job with proportional fonts. -
Added options for controlling lossless optimization of output. Currently, attribute reuse and character repetition (REP sequence) are implemented.
-
Added
-Ooption to the frontend. This controls the optimization level. -
Added a simple abstraction layer for terminal control sequences (
ChafaTermInfoandChafaTermDb). This allows for improved terminal support. -
FbTerm is now supported with
TERM=fbtermin the environment. -
Bug fixes:
- #43 Fix signal handler (reported by @elfring).
- [unfiled] Crash when invalid font paths were passed on command line.
- [unfiled] Small typo in fontgen's README (@timgates42).
- [unfiled] Bad contrast adjustment in images with transparency.
