This commit implements a standalone shared highlighter group that
highlights Jinja statements and expressions.
The traditional way of highlighting file contents is to hook on the
file extension, and assign a custom filetype/highlighter group to
the current buffer. However, since Jinja templates can be based on
any text file format in existence, we do not have a specific file
extension to hook, and consequently, no custom "jinja" filetype.
The user is expected to add the `jinja` highlighter whenever required:
```
require-module jinja
add-highlighter window/ ref jinja
```
Alternatively, file extensions that are known to occasionally pair
with Jinja can be hooked from the user configuration:
```
hook global WinCreate .+\.html %[
try %[
execute-keys -draft \%s \{%|\{\{ <ret>
require-module jinja
add-highlighter window/ ref jinja
]
]
```
The above hook auto-detects statements/expressions (respectively
{%…%} and {{…}} expansions), but will cause false positives
(in terms of highlighting), and therefore isn't part of `jinja.kak`
by default.
The `pick` command in a rebase commit is virtually a no-op, but other
commands actually do things. This commit visually communicates
that fact.
Fixes#3208.
If `-` is not first or last in a character classes, it matches a range based on
the character code. This applies to special characters as well as to
alphanumeric characters.
- Highlight `=` and `|` as keywords (like `->` and `:`)
- Highlight custom operators (I guess they aren't really custom as of Elm 0.19
but there are still a bunch "built in").
Highlighting arbitrary words in Swift comments should be done from the
user configuration, plus hardcoding the `red` color doesn't play well
with all colorschemes.
This commit allows using the <semicolon> expansion in commands, instead
of `\;`.
It makes commands look more elegant, and prevents new-comers from
falling into the trap of using <a-;> without escaping the semicolon.
