This avoids 100% CPU usage when we have pending fifo input while running
a shell process, as we will not end-up busy looping in pselect but not
reading the available data due to being only processing urgent events.
When a replaced buffer range atom was starting exactly at the
location we wanted to split onto the code would split *after*
that atom instead of before.

This avoids an issue when using `su` and running Kakoune which creates
a session directory owned by root and prevents the user from creating
more sessions.
Different terminals send different codes to indicate backspace, usually one of
\x08 or \x7f, so Kakoune blindly treated both as backspace. However, a given
terminal is only likely to use one of those, and mnemonic control codes like
<c-h> are a precious resource so we should endeavour to keep backspace and
<c-h> separate when we can. Luckily, termios tells us what code our terminal is
currently using, and Kakoune already reads the information at startup, so we can
just use that information.
Thanks to @krobelus for figuring out the C++ syntax required.
Fixes#3863.
Add that libexec directory to the PATH instead of the current kak
binary directory to avoid impacting other commands.
The libexec directory currently only contains a symlink back to
the Kakoune binary.
Various paths can run arbitrary commands (callbacks, hooks) which
could lead to the InputMode being popped off the mode stack, but
contrarily to the on_key method, we had no guarantees to be kept
alive.
Add a keep_alive RefPtr to this to ensure the mode survives till
the end.
Fixes#3915
When doing line completion, we previously used to not complete the line
if it had different indent to the potential completion.
This commit changes the behaviour to ignore indentation when completing lines.
Unfortunately this breaks some pretty useful use cases, such as inserting a
command ending with a new-line (as it now leads to an addtional command being
auto-completed on validation)
This reverts commit aab0be529f.
When pasting many words with <a-p> we can end-up with a huge
concatenated word and many selections, the previous code ended
up iterating from each selection cursor to that word start and
end to find the word under the cursor.
This could lead to performance issue as each selection would
trigger iteration on that huge word. This is unnecessary as
word completion has a word length limit, so we now take it into
account to avoid iterating to far from the cursor position.
The previous code was advancing from the general insertion point
for all selection, instead of iterating only once from insertion
point until the end of inserted text.
0 means stdin was closed, this is quite unexpected as we would usually
get a SIGHUP, but it looks like in some rare case this happens and
it leads to an infinite loop trying to handle stdin events (as it
will always be readable from now on).
Fixes#3557
Previously, Kakoune only handled ctrl-codes less than 27, representing them as
lower-case ASCII codes. For regular keys like <c-a>, that worked fine. However,
NUL became the unorthodox <c-`> and other ctrl-symbols (<c-\>, <c-]>, <c-_>)
weren't supported at all.
Now NUL is rendered as the more comfortable <c-space>, and the other ctrl-symbol
codes are properly decoded.
Fixes#2553.
