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.
