Since the default make error pattern spans until the end of the
line, make-jump select the whole line, moving the cursor to the end.
This is especially bad when the error message is very long and hence
the cursor movement scrolls the viewport so the file:line:col is no
longer visible.
Stop moving the cursor in `*make*` and `*grep*` buffers.
We already have highlighting to indicate the current line.
Given
make[1]: Entering directory '/home/johannes/git/kakoune/src'
main.cc:66:9: error: expected ‘}’ before ‘asdf’
If I select the whole second line, including the newline, make-jump
fails with an enigmatic "no such file or directory main.cc". This is
because `gl` does not move the cursor away from the newline. Fix it.
This appears to have regressed in 80d661e6a (rc/: More consistent
uses of regex syntax, 2017-09-29).
If a user modifies a grep buffer, we can end up in weird situations
where we try match a filename over multiple lines.
Let's rule out newlines in filenames here. There is an argument
this is a case of GIGO but we already do this for the corresponding
highlighters.
We also do it in make.kak, see ca225ad4d (Cleanup make.kak and optimize
the make-next/make-prev regexes, 2016-12-09). There is one case left
where a filename would theoretically span multiple lines. Fix and
optimize this too.
grep-jump and make-jump[*] support Windows-style paths like C:\path.
However grep-next-match and make-next-error don't, which suggests
that no one uses this feature. IIRC Cygwin mounts Windows drives in
proper Unix paths like /mnt/drive_c.
Let's remove it for simplicity and consistency.
This reverts commit 6c47b204e (Support windows style path in grep
output, 2014-11-11).
[*]: Though make-jump recently regressed in 8e5ca3f21 (rc/make.kak
introduce a new option to be back compatible, 2023-10-27) by failing
to capture the "C:" prefix.
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

As per man page eval(1p):

When not quoting `$kak_opt_makecmd` in the eval, the variable is split by
newlines and spaces and then joined by spaces to form the command. If there
were newlines in `$kak_opt_makecmd`, the command would be malformed.
To reproduce:
```kak
set-option global makecmd "
echo foo
echo bar"
make a b c
```
Expected output in the `*make*` buffer:
```
foo
bar a b c
```
Actual output:
```
foo echo bar a b c
```
This patch fixes this.
