This changelog contains major and/or breaking changes to Kakoune between
released versions.
== Development version
This version contains a significant overhaul of various Kakoune
features that can break user configuration. This was a necessary
change to make Kakoune command model cleaner and more robust.
* `%sh{...}` strings are not reparsed automatically anymore, they need
to go through an explicit `evaluate-commands`
* The `-allow-override` switch from `define-command` has been renamed
`-override`.
* The search prompt uses buffer word completion so that fuzzy completion
can be used to quickly search for a buffer word.
* The `wrap` highlighter can accept a new `-marker <marker_text>` switch.
* The command line syntax has changed to support robust escaping.
- `%sh{...}` is not expanded to multiple tokens automatically anymore,
to evaluate its output as multiple tokens/commands, use the
`evaluate-commands` command:
-------------------------------------------------------------
evaluate-commands %sh{ echo "first command; second command" }
-------------------------------------------------------------
- Escaping of `'` in `'...'` and `"` and `%` in `"..."` strings is done
by doubling up (`''`, `""` and `%%`) instead of using a backslash
- Bare words escaping has been tweaked.
See <<command-parsing#,`:doc command-parsing`>>.
* Various lists (options, registers...) in Kakoune are now written using
the command line syntax:
- `set-register` now take an arbitrary number of parameters and sets
the register to multiple strings. `%reg` expands to a list of strings.
- the `$kak_reg_*` environment variable is now a list, `$kak_main_reg_*`
provides the previous behaviour.
- `%opt` expands list options as list of strings.
- selection descs are whitespaces separated instead of `:` separated
* Highlighters syntax has changed to permit explicit naming and remove
highlighter specific name parameters (such as for the group highlighter)
`add-highlighter <path>/<name> <type> <params>` is the new syntax.
* Regions highlighters have been overhauled and are now specified with
a sequence of commands instead of a single one:
------------------------------------------------------------------
add-highlighter <path>/<name> regions
add-highlighter <path>/<name>/<region name> region <begin> <end> \
<type> <params>
------------------------------------------------------------------
The recursion regex is opt-in through a `-recurse <recurse>` flag.
They also are not necessarily groups anymore, a region can directly
apply any other highlighter
See <<highlighters#,`:doc highlighters`>>
* Highlighter type names have been unified, types that used `_` as
word separators, such as `show_whitespaces` are now using `-`
(`show-whitespace`).
* `a` on end of line is not treated specially anymore, it will start
inserting on the next character, which will be the first character
of the next line.
