std::function is not necessary when we just want to pass a type
erased callback that does not need to own its target. FunctionRef
provides that functionality for a much lower compile time cost.
Whenever a tool spawns the editor (e.g. Git), suspending it with ^Z is not
enough to be sent back to the calling shell - another ^Z is necessary.
Fixes#3061
The UI now can send a 'Scroll' key, whose value is the scrolling
amount encoded as a signed integer. This replaces the MouseWheelUp
and MouseWheelDown keys.
The NCursesUI now has a ncurses_wheel_scroll_amount ui_option that
controls that amount, it can be negative to swap scrolling direction.
Fixes#3045
First try to break at a whitespace, if that fails (likely because
that last WORD is too long for the wrapping width), then try to
wrap at a 'word' boundary (on a non alphanumeric character).
Fixes#3048
Falls back on old mechanism if `XDG_RUNTIME_DIR` is not set.
The ability to specify a session as "<user>/<name>" was removed, since
it isn't possible to compute the value of `XDG_RUNTIME_DIR` for another
user, we wouldn't have access to it if we could, and it would be awkward
to support this feature only when `XDG_RUNTIME_DIR` is unset. Also,
`rename-session` did not work when another user's session was specified.
Closes#3019
This commit implements formatting behaviour when the first character of a
docstring is a newline. In that case, the exact indentation level of the
next line will be removed from that line and all subsequent non-empty lines.
An error will be returned if a subsequent non-empty line does not have the
same indentation level.
The docstrings are always trimmed (surrounding whitespaces) whether the
first character is a newline or not, as was the case prior to this commit.
Example: the following declaration
```
define-command test -docstring %{
test: do something
Nothing really.
More
indented
lines.
} nop
```
would be rendered as
```
test: do something
Nothing really.
More
indented
lines.
```

History registers (for prompt commands, pipe primitive commands etc) are
populated interactively by the users, and currently have no size limit.
This commits silently drops the oldest entries in the storage space to
allow at most 100 entries, to prevent long-running editing sessions from
hogging memory for data most likely never used.
This commit makes the `*` and <a-*> primitives compose a search pattern
comprised of all the current selections, as opposed to only the main one.
All selections are OR'd into the default search register, which makes it
convenient to search for several identifiers already selected.
To retain the old behaviour, the following mappings can be used:
```
map global normal * ': exec -draft -save-regs "" %{<space>*}<ret>'
map global normal <a-*> ': exec -draft -save-regs "" %{<space><a-*>}<ret>'
```
Fixes#2994
The `parse_keys()` function is case insensitive when parsing function keys,
while the `key_to_str()` function always returns a capitalized key
description.
When users hook on the lowercase name of a function key,
e.g. `NormalKey <f10>`, and later hit that same key in normal mode, the
`key_to_str()` will convert it to the uppercase description ("<F10>").
This results into a hook with a lowercase regex predicate being unsuccessfully
matched against an uppercase key description by the hook manager, which
works on a case sensitive basis.
One solution could be to uppercase all function key descriptions passed as
hook filter upon declaration, but detecting that is not trivial as the
filter can contain more than just the simple <f\d+> data, e.g.
---
hook global InsertKey '<(?<name>\w+)>' %{…}
---
Another simpler solution that this commit implements is to allow only <F\d+>
descriptions in `parse_keys()`, and hope users will know not to use the
lowercase notation when declaring hooks.
Fixes#2907
The previous "optimized" history register logic was unfortunately
not restoring correctly as the order of entries in the history
register could have been mutated.
The hook parameter should not be adjusted for the prevention of
scrolling. Also, ensure that the last BufReadFifo is triggered if we
encounter an error or EOF after appending some data to the buffer.
Closes#2946
On my system, some optimizations are on by default (NixOS), resulting in
variables being optimized out on debug builds. It *seems to be*
something about a "_FORTIFY_SOURCE" feature? In any case, `-Og` is
documented as "Optimize debugging experience".
Using <fg>,<bg>+<attr>@<base> will apply the given fg color,
bg color and attributes on top of base dynamically. Simply giving
<base> is a shorthand for default,default@<base>.
Inspired by the discussion in #2862
Sometimes we really need to have a String instead of a StringView,
but some of those strings might not need to own their data. Make
it possible to explicitely construct a String that does not own
the underlying buffer.
Use it when parsing balanced strings.
This permit to choose if files should be written by overwriting their
content (the default), or by writing to a separate temporary file
and rename it to the current file.
As discussed in #2036
The current implementation is wrong as it crosses basic blocks
boundaries. Doing basic block decomposition of regex is probably
a tad too complex for this single optimization.
Fixes#2711
This should reduce the number of allocations as the memory allocated
for the thread stack and the saves can be re-used between runs instead
of being cleared every time.
The current implementation treats left mouse button clicks as a
generic "mouse press" modifier, this commit extends the list of
modifiers by adding a "right mouse click" one.
The proper way to implement this would be to ship the coordinates
of mouse key press events in each `Key` object, and pass whichever
button was clicked as a codepoint value (instead of coordinates
currently), but this would require more work.
This commit allows:
* right clicks to set the cursor of the main selection
* control-right clicks to merge all the selections, and then set
its cursor
Fixes#843
By setting the ncurses_builtin_key_parser ui_option to true, we
can disable ncurses parsing of key strokes to get less portable
parsing but support for more complex modifiers.
Probably, the extra «s» at the end of «exist» was added accidentally. A verb after «does not» in Present Simple definitely shouldn't have this extra «s».
Ideally, something better should be done (re #2554) but this is a decent
intermediate step for some useful keys.
Note: NCurses supports parsing these keys when shifted (KEY_SR,
_SLEFT, S_RIGHT, etc), but it does not do the same thing for the other
modifiers.
Not having the `test` target (in the Makefile) depend on the `kak` one
prevents users from running commands that make use of parallelism, e.g.:
$ make -j all test
The above command sometimes results in the test suite running before
the binary has been compiled and symlinked, resulting in failures.
SIG_IGN is inherited after 'execve' and requires us to reset
that signal handler, which does not work well with vfork on
OSX. Using an empty function does the trick and will be auto
reset to default on exec.
When large buffers have been opened, copying Kakoune's memory
page descriptors can get pretty slow, making fork more expensive
than necessary.
vfork avoids that problem. While not strictly conforming, it seems
the few calls we do before execve (open, close, dup2 and
set_signal_handler) would not cause any problems on platforms we
care about.
the buffer name was not a very interesting information, whereas
the buffer range allows a hook to run only on the appended text
instead of all the buffer.
m_last_setup was not storing the actual position that was used to
redraw the window, but the previous one, leading to an additional
spurious redraw immediatly after (triggered by window position not
believed to be the one at last redraw).
Fixes#2562
As we do at most one push_next per step_thread, and we pop_current
before step_thread, we can avoid a branch there at the expense of
sometimes growing unecessarily (once).
It seems unlikely this would give performance gain, as buffer
lines are always accessed when we read that field, leading to
all the necessary data already being in memory. Removing it
reduces the size of a BufferIterator, which are already pretty
hefty objects.
The RegexHighlighter range cache can get pretty big in nested
regions use cases, and maintaining it can become pretty costly,
so if it hits a certain size, just drop it.
Should improve performances in #2454
This should greatly reduce memory usage by only caching matches
for ranges that needs to be highlighted, in the case where multiple
regions are nested, this means only the topmost region needs to parse
and cache the whole buffer, other regions highlighter will only ensure
the lines for the ranges they are called up are cached.
Fixes#2454
This adds a limitation that capture matching on regions only works
if the regions start/end/recurse match is less than 65635 byte long.
With this limitation we can reduce the RegexMatch struct size to 16
bytes instead of 32.
This is still not good enough,but should slightly improve high memory
usage as reported in #2454
This commit also introduces a regression in that I decided that the best way to
avoid overly long and confusing names was to rename the current shell-*
switches to script-*, and have the shell command completion be
shell-completion.
renamed script-{completion,candidates} to shell-script-*
Updated docs with new switch names
Added -shell-completion switch to x11-repl and kitty-repl
Final is more granular, it consists of FinalFg (f), FinalBg (g)
and FinalAttr (a) which control if a face's fg, bg, or attributes
fully overwrite the previous face (instead of merging) and if
following faces apply on top of this face or not.
Fixes#2388 if the Whitespace face has the FinalFg flag.
Add <c-w> and <a-d> (along with <c-W> and <a-D> that work on WORDs),
and <c-y> which pastes the transient clipboard contant (which saves
big erase, such as word erase and line end/begin erase).
Fixes#2355
In the end, no better solution materialized so far, and custom
Kakoune line editing bindings are hard to remember. Using well
known readline bindings seems just more convenient.
Closes#800, although it does not contain all the binding proposed
by it (I might accept a few additional ones, such as <c-w>, but not
too much, I still see that as a hack pending a nicer solution).
