This allows to jump from a mail buffer that contains an inline diff
to the source files (most accurate when the patch has been applied
locally).
This makes the diff module a mandatory dependency; we could relax that.
When reading and writing emails that contain patches (possibly
email-quoted), it can be convenient to the jump to the source file.
Allow this by making diff-jump (bound to <ret> in git-diff
buffers) ignore leading email quotes ("> "). A line that starts with
"> " should not occur in a unified diff, so this won't affect other
use cases.
Observe that diff-jump even works around interleaved replies; they
will not affect the computed line numbers because we ignore lines
that don't match ^(> )*[ +-].
git-diff-goto-source is specific to diffs produced by Git. This patch
generalizes the logic and moves it to a new diff-jump in diff.kak.
The main differences are:
- diff-jump handles plain file diffs (i.e. without the -r option). These
have no "diff" line. This means that it needs to parse +++/--- instead.
- diff-jump can go to the old file, not just the new one.
- diff-jump allows to override the base directory and the number of
directory components to strip.
git-diff-goto-source was implemented with several nested try/catch
blocks. Implementing the extra features would have added more
nesting, redundancy or hidden options. To avoid that, I ported the
parsing logic to Perl (which git.kak already depends on). Maybe
it's possible to do the same in awk.
Potential concerns:
- We could move diff-jump to a new rc/tools/diff.kak but then it's not
obvious where the "diff" module belongs to.
- Should diff "diff-jump -1" be spelled "diff-jump -p1"?
In future, the diff parser could be reused to implement a vimdiff-style
feature: given a diff and the "old" line number, we can compute the
corresponding "new" line number. Perhaps diff-jump should get a -client
argument.
We want to move git-diff-goto-source from rc/tools/git.kak
to rc/filetype/diff.kak (or should we could create
rc/tools/diff.kak?). Either way, create the diff module so we can
formalize this dependency.
Currently this module only provides highlighters, so require it
wherever we reference them.
Keep the diff-select-{file,hunk} commands outside the module because
people might already use them in git buffers.
When `set` or `se` is found at the start of the modeline, it should stop parsing options after `:`.
When `modeline-parse` is called in the following file, it should _not_ recognize `tabstop=4` and `invalid_option=3`.
```
# kak: set indentwidth=0 tabstop=16: tabstop=4 invalid_option=3
```

adds the ability to press <ret> within a hunk and navigate to the original
source code. This can be useful because one often needs to go back and forth
between the diff and the full source code.
- You can press <ret> anywhere _within_ a hunk i.e. lines that start with
` `, `+`, `-`. You will be taken to the exact line in the source that corresponds
to where you pressed <ret> in the hunk. It actually does not make sense
to press <ret> on a `-` line because that does not exist anymore but
in that case you are taken to a nearby line in the hope this is still useful.
- You can also press <ret> on a range line (lines that
look like @@ ... @@). If you press <ret> on anywhere on a range line e.g.
```
@@ -120,3 +123,4 @@ fn some_function {
```
The code will try to navigate to the section heading "fn some_function {"
Note that the section heading is _not_ necessarily located at the
range line (in the above example the range line is 123).
- You can press <ret> on a +++ line also and you will be taken the first
line of the file
Caveats:
- Navigation to the original source file will be accurate only if any edits to
the original source file have been saved to disk, because otherwise
they will not be detected by the `:git diff` or `:git show` commands
- This feature should work well for most typical uses e.g. `:git diff`, `:git diff HEAD^`
`:git diff <some-sha1>`. In fact this feature should work in all scenarios when
the *current files* on disk are being compared _with_ some arbitrary git revision/staging.
It will be less useful in other scenarios when two arbitrary revisions are being
compared to each other or when you are trying to compare staging to some revision.
For example when you invoke `:git diff --staged` you are trying to compare staging
with HEAD but are navigating to what is currently on disk (which may be different
from staging).

C has header and source files and you need to often switch between them.
Similarly OCaml has .ml (implementation) and .mli (interface files) and
one often needs to switch between them.
This commit provides a simple functionality that allows you to accomplish this.
As per man page eval(1p):
> The eval utility shall construct a command by concatenating arguments together,
> separating each with a `<space>` character. The constructed command shall be
> read and executed by the shell.
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.
OCaml does not have line comments, and as far as I can tell neither
does Coq. Setting it to '' (like markdown and html do) throws an error
that can be handled or displayed instead of inserting the default '#'.
The closing ``` in the following example was not detected because the
indented code block highlighter was higher up in the hierarchy than the
fenced code block highlighter:
```
indented
```
The codeblock highlighter used to be inline so that it has an effect
inside listblocks. This commits adds a listblock/codeblock highlighter
as a replacement.
Fixes#4351
- Also insert "end" after "do", "else" and "elseif"
- Do not insert "end" after strings or comments containing keywords
- Only insert "end" if the block is empty
An example of the last item is if we want to add a new line to the start
of an unclosed block that already contains statements. @ is the cursor.
-- before
if a then@
x = 1
y = 2
-- after
if a then
@
end
x = 1
y = 2
In this case, inserting the "end" before the statements is probably not
what the programmer wants. It might make more sense to insert the "end"
after the statements, but that is potentially confusing due to spooky
action at a distance. I think the least confusing thing to do in this
situation is to not insert the "end".
This commit makes several improvements to the Lua indentation logic.
- Don't indent if the keyword is inside a string or comment
- Indent inside "do end"
- Indent inside "repeat until"
- Indent after a line ending with "{" or "("
- More accurate un-indentation for the "end" keyword
For the last point, previously we tried to match the indentation of the
starting keyword of the block. However, sometimes this guessed wrong
and produced the wrong indentation, as the following example shows. The
new logic is to indent the "end" by one less level than the contents of
the block.
while true do
if false then
end
end -- This was incorrectly matched with the "if"
