Before, sed would add quotes to every line of the single multiline argument,
causing the final quoted argument to "split ... command" or screen to contain
unquoted newlines such as this (from kakoune-cr):
tell application "iTerm"
tell current session of current window
tell (split vertically with same profile command "env PATH='...' 'sh' '-c' ''
' export KAKOUNE_SESSION=$1'
' export KAKOUNE_CLIENT=$2'
' shift 3'
''
' [ $# = 0 ] && set \"$SHELL\"'
''
' \"sh\"'
' ' '--' '51909' 'client0' 'terminal' ") to select
end tell
end tell
Instead of using sed to do this which operates on single lines at a time, simply
use printf to insert ' quotes before and after the entire argument.
At the moment, inserting a new line while being in a comment result in a
"//<indentation>" instead of "<indentation>//".
To fix this, we just re-order both InsertChar hooks.
Positional arguments in awk’s printf is a feature that is only available
in the GNU implementation of awk (gawk). So the ctags auto-completion feature
was broken in Kakoune if the installed version of awk was nawk or mawk.
This simple change makes it retro-compatible with those versions.

When calling `:gopls definition`, the gopls LSP server returns the location of
the selected definition. Then, `gopls.kak` tries to parse this output to
feed the `:edit` command and open the file in Kakoune. To do this, it
uses `sed` to transform `<path>.go:<line>:<colstart>-<colend>` to `<path>.go
<line> <colstart>`. However, if the `<path>` contains a dash character,
the `sed` will fail and strip everything after this first dash, removing
the line and columns information.
Closes#4776
When running modeline-parse on this file:
# kakoune: filetype=ledger:indentwidth=4
I get this error from dash (and a similar one from bash):
sh: 53: readonly: key: is read only
This is because the readonly variable "key" is used elsewhere, both
times as global. Fix this by making both variables local. While
at it, remove an unused variable.
Fixes#4478
This is equivalent to a change to grep.kak in 649e252f7 (bring *grep*
buffer to front in context of toolsclient, 2020-08-14).
If a toolsclient is set, make-next-error (and make-previous-error) will
jump to %opt{make_current_error_line}. This is wrong if the toolsclient
does not show the *make* buffer. In that case make_current_error_line
is undefined and we end up showing the goto menu. This has occasionally
been annoying me for a long time but I never bothered investigating.
Fix this by switching to the *make* buffer. The potential downside
is if make-next-error is run from the toolsclient, where we no longer
jump to the error but that's fine because we can use <ret>.
We can maybe improve this later by extending the logic, see
https://github.com/mawww/kakoune/pull/3656#pullrequestreview-472052285
I can't think of a case where a URL would not start at a word boundary.
Let's add that to the regex. In addition to correctness, this also
slightly improves performance because matching can stop earlier.

There have been proposals to add more language aliases to markdown.kak
(#4592) and allow users to add their own aliases (#4489).
To recap: various markdown implementations allow specifying aliases
for languages. For example, here is a code block that should be
highlighted as filetype "haskell" but isn't:
```hs
-- highlight as haskell
```
There are lots of aliases out in the wild - "pygmentize -L" lists
some but I don't think there is a canonical list.
Today we have a hardcoded list of supported filetypes. This is hard
to mainta, extend, and it can impact performance.
This patch simply attempts to load the module "hs" and the shared
highlighter "hs". This means that users can use this (obvious?) snippet
to add their own aliases:
provide-module hs %{
require-module haskell
add-highlighter shared/hs ref haskell
}
Untrusted Markdown files can load arbitrary modules, but that was
already true before, and modules are assumed to be trusted anyway.
Since language highlighters are now loaded *after* the generic
code-block highlighter, we need to make sure the language highlighters
take precedence. Do this by making them sub-regions of the generic one.
Closes#4489

(These numbers depend on another optimization.)
Filetypes markdown and restructuredtext reuse highlighters from other
filetypes to highlight code blocks. For example, to highlight a code
block of language foo they essentially do
require-module foo
add-highlighter [...] ref foo
This works great if the module name matches the shared
highlighter. This is the case almost all scripts in rc/filetype*.
The only exception is kakrc.kak: the highlighter is named "kakrc"
(just like the filetype) but the module is named "kak".
This requires weird hacks in markdown/restructuredtext. Ideally we
could remove this inconsistency by renaming both the filetype and the
highlighter to "kak" but that's a breaking change. Until we do that,
let's add an alias so we can treat filetypes uniformly. This helps
the following commits, which otherwise would need to add ugly extra
code for kakrc highlighters.
The following commit will generalize this approach, allowing users
to add arbitrary aliases.
As reported in

ledger.kak defines a region end that matches every character of
the buffer. This causes performance issues for large buffers.
Since the affected regions are only ever filled with a single color,
just use a regex highlighter instead of a region highlighter.
This improves performance when loading the file for the first time.

After opening a markdown file
```b
```
```c
int main() {}
```
markdown-load-languages will run an "evaluate-commands -itersel".
The first selection makes us run "require-module b", which fails
because that module can't be found. Since -itersel only ignores the
"no selection remaining" error we fail to run "require-module c". Fix
this by ignoring errors.
