When using `eval` a new scope named 'local' gets pushed for the
whole evaluation, this makes it possible to temporarily set
an option/hook/alias...
Local scopes nest so nested evals do work as expected.
Remove the now trivial with-option command
MacOS uses an old GNU make that does not support the != syntax.
That syntax is not Posix (yet, it is accepted for next standard) but
we really need a way to call the shell from a Makefile. Hopefully we
can remove this soon (not holding my breath though)
Fixes#5117
In a noninteractive shell, asynchronous commands ignore SIGINT and
SIGQUIT. We typically use such shells to feed fifo buffers which we
do want to cancel them on Control-C. Make it so.
Same for SIGQUIT; that one is not typically used but I expect that
along the Kakoune server it kills any child processes that (haven't
been daemonized).
Note that for unknown reasons, Bash already doesn't ignore SIGINT in
async processes that use "eval".
Note that Dash has a bug that prevents this from working;
proposed fix is at
https://lore.kernel.org/dash/20240329153905.154792-2-aclopte@gmail.com/
(While at it balance out some parens, to help the m command)
Overloading SIGTERM like that causes issues; specifically if the
editor is invoked (without exec) from a wrapper script.
By sending SIGTERM to whole process group, we kill our parent process
(the wrapper script) which then sends SIGTERM to Kakoune. By this
time Kakoune has already reset the SIGTERM handler to the default
action and terminates.
We can use a different fix for the problem that some shells don't
cancel "make", see the next patch.
This reverts commit ec44d98347.
A couple of semi-opinionated choices were made in this implementation:
1. The guide is hidden in the first column.
2. The indent guides are highlighted using a new `WhitespaceIndent` face.
3. Nothing is done to continue the guide through empty lines. I believe this to be the correct approach,
at least as long as it is kept as a part of the show-whitespaces highlighter. However some people's
oppinion may differ, and if so, that could be implemented.
4. The guides default to on, like the other show-whitespace options. Default character is "│".
5. Spaces between the indent guides are currently highlighted as other spaces.
Other reasonable options would be no replacement, -tabpad, or a similar -indentpad.
6. Guides are disabled by passing `-indent ""`.
7. Indent guides are separate from tab highlighting.
Additionally, we could consider adding a separate face for the "current" indent level as many editors do,
but this is a bit harder in kakoune because of multiple selections.
Closes#2323
tabs <-> space conversion functions did not create a ScopedEdition
leading to uncommited modifications. Fixing this did fix the
interactive error, but that error still existed in non interactive
context so redo now considers there there is no redo child if there
are uncommited modifiations (which is correct as this means we are
currently creating a new leaf in the undo tree)
Fixes#5124
Only record non-synthetized insertions, removing the need to
re-record on replay and fixing the last replay getting dropped by
macro execution.
Fixes#5122
<c-n>/<c-p> handling in insert was always dropping the last key in
the last_insert() vector (in order to replace it with the actual
completion text inserted), this was not valid for synthetized keys
that are not added to that vector in the first place.
Take the opportunity to merge insert completion handling code between
<c-n>/<c-p> and direct menu selection.
Fixes#5120
The wrap highlighter was pulling all lines until the cursor, regardless
of whether the cursor was going to be made visible, this could lead to
a display buffer containing much more lines than the actual viewport
which eventually could lead to menu being anchored out of view that
was leading to past-the-end buffer accesses.
Fix the wrap higlighter not to pull lines up to the cursor when it
is not tasked with making the cursor visible, and always trim the
eventual extra lines after highlighting.
Fixes#5118
After extracting the whole buffer content, a line can end up with
only non-range highlgihters pending which makes its range become
0.0,0.0, after running highlighting on the extracted range it gets
re-inserted but taking the min of existing range and inserted range
wrongly returns 0.0. Avoid this by detecting that the 0.0,0.0 range
does not actually mean anything when we have no ranged atoms.
Fixes#5001
It appears that the command to specify the `PREFIX` variable to the makefile has changed.
I had to run `make PREFIX=$HOME/.local install` in order to override the hardcoded `PREFIX` value in the makefile. I infer that the instructions need to be changed for those who don't know. (TIL. ;) )
Framed info boxes need one cell for the border and one for inner
space padding. That's 4 extra columns when counting both sides.
Frameless boxes have neither border nor padding so 0 columns here.
Closes#5106
Commit e43c7d6ab (Use complete-command for the :doc command,
2022-10-19) forgot to carry over the "-menu" flag, which means that
:doc completions are no longer auto-selected, even though they are
the only valid inputs.
Fix that.
Closes#4790
This sometimes allocates saves too eagerly, but it removes a branch
in release saves that executes on every thread failing which seems
slightly better.
When creating a new save, we had to clear all iterators to have valid
values. This operation is relatively costly because it gets optimized
to a memset whose call overhead is pretty high (as we usually have
less than 32 bytes to clear). Bypass this by storing a bitmap of
valid iterators.
