Kakoune Versions Save

This is a bug fix release

• Fix compilation errors on FreeBSD and MacOS using clang

• <a-u> and <a-U> now undo/redo selection changes; the previous meaning of moving in history tree has been moved to <c-j> and <c-k>

• %exp{...} expansions provide flexible quoting for expanded strings (as double quoted strings)

• <c-g> cancels the current operation and goes back to the main event loop, this provides an escape hatch when Kakoune seems to hang due to a costly operation

• show-matching -previous highlighter will fall back onto the character preceeding the cursor

• complete-command to specify and change how a command is completed

• p, P, ! and <a-!> commands now select the inserted text

• x now just extends the selection to contain full lines (as <a-x> did) <a-x> trims partial lines from the selection (as <a-X> did)

• User mappings is now bound to <space> while keeping/removing main selection moved to , and <a-,>

• Prompt history registers %reg{colon}, %reg{slash} and %reg{pipe} now have reverse chronological order

• Executing user mode mappings no longer adds to prompt history registers.

Bug fixes after feedback from 2021.10.28

• Support for curly and separately colored underlines (undocumented in 2021.10.28)
• Fixes for terminal flickering
• Fixes for command and response fifo corner cases

• g and v do not auto lower case the next key, so GL needs to be manually mapped to Gl for example.

• Fix flickering issues on some terminals such as the linux console

• command and response fifo support

• Shell expansions only trim the last trailing newline instead of all of them to make is possible to losslessly pass text through %sh{...}.

• set-option -remove support for subtracting/removing from option values

• Menu completions such as command name completion are now auto-inserted on space

• write -atomic was replaced with write -method [replace|overwrite] to make both write methods available explicitly

• write <filename> will fail if the given filename already exists and is a regular file. Use the -force switch to override that behaviour.

• ncurses was replaced with a custom terminal escape sequence backend, ncurses is not a dependency anymore.

This is mostly a bugfix release.

• Daemon mode (-d switch) does not fork anymore.
• Fix crash on completion.

• Introduce User hook support.

• The bold and italic faces are no longer built-in. Highlighters are expected to use face attributes (+b and +i, respectively) to decorate text.

• The lint-enable command no longer needs to be called to display linting errors. The lint-disable command was renamed into lint-hide-diagnostics.

• The +<length> part of a range-specs highlighter consistently refers to the length of the target range.

• clients stdin is transferred to the server, making it possible to pipe into kak -c <session>

• Faces can have an alpha channel, specified using the rgba:RRGGBBAA format.

• replace-ranges highlighter now support empty and multi-lines ranges

• %val{...} now expands to list of strings, $kak_quoted_... now work as expected with these.

• *SetOption hooks filter string will contain a value only for options of int/str/bool types to avoid performance issue with generating those on more complex option types.

Mostly a bug fix release for various issues in v2019.12.10

• Expose history tree through $kak_history and $kak_uncommitted_modifications

• InsertCompletionHide parameter is the list of inserted ranges

• Arrow keys and <home>, <end> are not normal mode commands anymore but default key mappings.

• ModeChange hook parameter now takes push: or pop: prefix, InsertBegin, InsertEnd, NormalBegin and NormalEnd were removed.

• -verbatim switch in evaluate-commands for perfect command forwarding to another context.

• WrapMarker face used by wrap -marker highlighter

• info supports markup with the -markup switch

• rename-buffer gained -file and -scratch switches to support converting buffer types.
