Sometimes a patch that fails to apply will apply cleanly after
adding -3. Also sometimes we do want to apply with conflict markers.
So this is another somewhat common option.
Sorry I did not test my earlier patch in production. It passes
blame flags via the environment. On a 5000 line file this results in
"execve failed: Argument list too long" errors.
Use a different way of checking whether blame info is shown.
Since :patch transforms its inputs into context-only lines, we can
easily get into a state where a file diff has only context lines.
git apply does not accept a "diff" without any hunk, so let's skip
that.
It is not an obviously better result than just displaying results
from each tag file, so remove sorting to take advantage of live
completion updates
As discussed in #5081
As of recently, shell script candidate completions are computed in
the background, and displayed incrementally.
Sorting completions means we can't show partial results.
We do this for "ctags-search"; but if there is only one ctags file
there is already a sensible order (which is slightly different than
what GNU sort does). So let's preserve the order in that case.
The number of completions is probably too high for an order to be useful.
Similarly, for "man", sorting is probably not very helpful because
there are so many results.

The last update is from 2017, it's pretty outdated. Current
support was combined from existing languages such as Ruby and
Zig and tweaked to fit the Pony language.
Today "with-option foo bar command-that-fails" fails with
Error: 1:1: 'evaluate-commands': 1:1: 'with-option': 2:5: 'evaluate-commands': 4:9: 'evaluate-commands': 1:2: 'no-such-command': no such command
but leaks the option value. Fix this by resetting the option and
rethrowing the error. Unfortunately the original stack trace is lost
(questionable behavior inherited from C++?).
The awk-generated highlighters in scheme.kak need '\\.' to obtain '\.'
in the generated kakscript output. Fix the inf/nan rule (which should
generate '(?:inf|nan)\.0') to read '(?:inf|nan)\\.0' in the awk.
Kakoune's balanced strings require that delimiter characters nested inside
them are also paired, so for example in %{ }, each nested { must occur
before a corresponding } to balance it out.
In general this will automatically be the case for code in common scripting
languages, but sometimes regular expressions used for syntax highlighting
do end up containing an unbalanced bracket of one type or another.
This problem is easily solved because there is a free choice of balanced
delimiter characters. However, it can also be worked around by adding
a comment which itself contains an unbalanced delimiter character, to
'balance out' the unpaired one in the regular expression.
These unbalanced comments are not ideal as the semantic role they perform
is easy for a casual reader to overlook. A good example is
catch %{
# indent after lines with an unclosed { or (
try %< execute-keys -draft [c[({],[)}] <ret> <a-k> \A[({][^\n]*\n[^\n]*\n?\z <ret> j<a- gt> >
# indent after a switch's case/default statements
try %[ execute-keys -draft kx <a-k> ^\h*(case|default).*:$ <ret> j<a-gt> ]
# deindent closing brace(s) when after cursor
try %[ execute-keys -draft x <a-k> ^\h*[})] <ret> gh / [})] <ret> m <a-S> 1<a-&> ]
}
in rc/filetype/go/kak. Here, it is not instantly obvious that the comment
containing an unmatched { is required for correctness. If you change the
comment, delete it or rearrange the contents of the catch block, go.kak
will fail to load, and if you cut-and-paste this code as the basis for
a new filetype, it is a loaded gun pointing at your feet.
Luckily, a careful audit of the standard kakoune library turned up only
three such instances, in go.kak, hare.kak and markdown.kak.
The examples in go.kak and hare.kak are easily made robust by replacing
a %{ } with %< > or %[ ] respectively. The example in markdown.kak is
least-intrusively fixed by rewriting the affected regular expression
slightly so it has balanced { and } anyway.
The current handling of preprocessor directives in filetype/c-family.kak
leads to a wall of solid colour for more complicated #if or #define
directives, although #include is already nicely highlighted.
Instead of highlighting an entire directive with the meta face, highlight
just the #define, #if or #elif keyword as meta, treating the rest of the
directive as normal c-family expressions. This significantly improves
the readability of complex macro definitions.
For directives other than #define, #if and #elif, we treat the rest of
the directive as an opaque string in normal face rather than trying to
highlight it, covering cases like #error, #pragma, etc. where the rest
of the line is an error message string or other non-expression content.
This does the right thing for #ifdef and #ifndef too, as we don't highlight
identifiers in c-family text so their arguments should be normal face
anyway.
We already pull in the diff module in mail.kak to enable the nice
:diff-jump behaviour on inline patches. Also enable the shared/diff/
highlighter underneath our shared/mail/ highlighter for inline diffs,
listing it first so mail patterns take precedence over diff patterns.
De-emphasise signatures including the standard '^-- \n' separator in the
same way as quoted text in a reply.

When using either of
set-option g completers option=my_option
prompt -shell-script-candidates ...
While the search text is empty, the completions will be sorted
alphabetically.
This is bad because it means the most important entries are not listed
first, making them harder to select or even spot.
Let's apply input order before resorting to sorting alphabetically.
In theory there is a more elegant solution: sort candidates (except
if they're user input) before passing them to RankedMatch, and then
always use stable sort. However that doesn't work because we use a
heap which doesn't support stable sort.
Closes#1709, #4813
prompt has fuzzy filtering which is more discoverable than the menu
mode's regex filtering (because that one needs / to trigger it).
There are no important differences left, so replace the menu builtin
with a prompt-based command.
prompt does not support markup in the completion menu, so drop that
feature for now.
Today I can control "terminal" and "new" by changing the terminal
alias but I always need to choose a concrete implementation, like
"tmux-terminal-horizontal", even when there is otherwise no need to
mention tmux in my config.
Allow to configure windowing system and window placement independently
by introducing dedicated options.
This allows to create mappings that work in any windowing system like
map global user c %{:with-option windowing_placement window new<ret>}
map global user '"' %{:with-option windowing_placement vertical new<ret>}
map global user '%' %{:with-option windowing_placement horizontal new<ret>}
For windowing systems that don't support all placements, you can wrap
the above in try/catch to fall back on the "window" variant which is
defined for all windowing systems.
When using multiple (nested) windowing systems, you might want to
add mappings like
map global user t %{:with-option windowing_module tmux new<ret>}
map global user T %{:with-option windowing_module wayland new<ret>}
---
This changes the default "terminal" alias for some modules. In
particular, instead of delegating to
iterm-terminal-vertical
screen-terminal-vertical
tmux-terminal-horizontal
wezterm-terminal-vertical
it will now by default delegate to the respective "-window" variant.
We could maintain backwards compatiblity here by setting the
"windowing_placement" option accordingly, but the new behavior seems
more logical?
Also, this removes the "terminal-tab" alias which was only defined
by the kitty module.
We could try to keep the alias approach and implement a "with-alias"
command, however that approach can only capture both dimensions
(windowing system and placement) if we add tons of commands
like "terminal-horizontal" (with implied windowing system) and
"tmux-terminal" (with implied placement).
Side thought: we could also get rid of the "focus" alias and instead
define
define-command focus %{
"%opt{windowing_module}-focus"
}
Closes#3943, #4425
Running an invalid command like "grep -abc" shows no output at all.
Let's give better feedback by showing the error message from grep.
We used to do this until an unrelated change, bd5955c73 (grep: remove
eventual \r, 2013-02-13).
This adds a somewhat discoverable frontend for common uses of the
patch command.
Here are some frequently used commands
# apply selected changes
git apply
# revert selected changes
git apply -R
# stage selected changes
git apply --cached
# unstage selected changes
git apply --cached -R
# apply selected changes and stage them
git apply --index
For everyday use that's a lot of typing so I recommend adding mappings.
One of the features I miss most from Magit/Fugitive/Tig is to
apply/revert/stage/unstage individual hunks or even exactly the
selected line(s). This provides a much more convenient way of
splitting changes than "git add/restore -p".
Implement a "patch" command that applies the selected lines within
a diff by piping them to the "patch" program.
It can also feed other programs like "git apply" (see the next commit).
Original discussion: https://discuss.kakoune.com/t/atomic-commits-in-kakoune/1446
Interestingly, :patch is defined outside the "patch" module. This is
to make it readily available for interactive use.
Putting it into the module does not save any work.
I tentatively added a patch module anyway so we can explicitly declare
this dependency.. although there is the argument that this is not
really needed?
This commit adds `diff_add_char`, `diff_mod_char`, `diff_del_char` and `diff_top_char` as `str` options, with typical
defaults.
This commit also replaces the hard coded +, _, ≃, etc. hardcoded characters in `git update-diff` to use the options from
above.
