modeline-parse leads by matching an expensive regex against the entire buffer,
which can take a long time on huge files.
Perl takes too long on this regex and it seems not even ripgrep
optimizes the \z component
$ ruby -e '10000.times { puts "a" * 10000 }' > big
$ time rg --multiline --only-matching '\A(.+\n){1,5}|(.+\n){1,5}\z' big | wc -l

Let's lose the regex.
Fixes#4911
The x11-terminal command spawns a potentially long-lived terminal
process. The terminal can is completely independent of the Kakoune
session that created it.
Due to how it's implemented, the spawned terminals will have
environment variables "kak_opt_termcmd" and "kak_quoted_reg_a"
set. This can be surprising, especially since, by convention, the
environment contains no lowercase variables. Let's stop exporting them.
When launch matches using `id` kitty tries to match against tab id
before matching windows. When there are multiple tabs it's likely to
match a tab before matching a window.
Use `window_id` directly to avoid any possiblity of matching tabs.
This is only needed for `kitty @ launch` for other commands there is
no specific `window_id` field.
This continues the work started by 0a9c90fec (rc: use a separate
*-insert hook to auto-insert comments, 2021-04-17).
The one that's left is Rust but that one is trickier.
Why?
Most users who pass the current selection to grep likely do not intend to pass
the selection as a regex input string.
This makes the grepcmd use an additional -F flag to perform literal-string
matching for the current selection. The -F flag seems to be the standard flag
for literal-string matching in every grep implementation I've found.
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 paste the comment and indent after the newline
initial indentation.
Just like the parent commit but for tmux-repl-* commands.
Note that tmux-repl-set-pane without arguments is kind of broken; it
increments the current pane ID, which only works in the most basic
scenarios. We should probably replace it with something better,
with menu completions etc.
