The previous implementation could yield different positions when
iterating forward and backward, leading to confusion in boost regex.
This makes an existing problem a bit more visible: iterating with
to_next and with read_codepoint wont behave the same way, as
read_codepoint will put the iterator onto the byte following the
utf8 codepoint, whereas to_next will put it on the next utf8
character start byte, which might be different if the buffer content
is not valid utf8.
Fixes#1195
This commit allows "forced" writes to a write-protected file, by
attempting to temporarily grant the current user write permissions on
it. After the buffer has been written, the previous permissions are
restored if the file existed, or set to 0644 otherwise.
That means we wont have a very nice interaction between show_whitespaces
and column highlighters, but thats the simplest fix for now, if we want
a better behaviour we need to introduce a way to know that a replaced
range is splittable (meaning it means to have the same amount of columns
as the range it replaces)
Fixes#1275
We were letting stdin untouched, which meant child processes had
access to our terminal input. That meant `!fmt` was trying to read
from our terminal input and catching keystrokes.
Fixes#1281
This commit allows a help message to be printed when a `-help` flag is
passed to the editor, which will subsequently quit after a summary and a
description of all the flags available have been displayed.
The GNU convention (passing a single `--help` argument to the program)
is also supported, although undocumented.
The man page also now documents the `+:` argument, although unrelated to
the original changeset.
`tmux` will start new processes (e.g. when creating panes or windows)
with the same environment it was started with, which means that if the
$TMPDIR variable was overriden for the kakoune server from within
`tmux`, newly created panes/windows won't have access to the server
socket to sustain a session.
This commit fixes the issue by always exporting the $TMPDIR variable
from the parent `tmux` environment to the new processes.
Fixes#1319
Based on the vim gruvbox colorscheme. I made it as close as possible to the
original vim colors, but had to make some changes due to kakoune's highlighting
scheme being different than vim's.
