Previously, if you opened a new line after an underlined heading (what
the CommonMark spec calls a "Setext heading") or inserted a newline into
a line that started with `**strong emphasis**` the Markdown autoindent
hook would assume the leading symbols were list bullets and paste them
at the beginning of the new line.
However, the CommonMark specification says that list bullets must be
followed by at least one horizontal whitespace character, so Setext
heading underlines and strong emphasis are not valid list bullets and
should not be matched by the autoindent pattern.
This commit changes the regex that selects the pastable prefix of the
previous line so that it must match either:
- One or more `>` characters with optional whitespace between them
(a blockquote prefix), optionally followed by a list bullet; or
- An optional blockquote prefix and a list bullet
Since we don't strictly need either the blockquote prefix nor the list
bullet, we could concievably just make both optional... but for lines
without either, the regex would find a zero-length match, and for the
purposes of copy/paste Kakoune treats that as a one-character match.
Therefore, the regex is written to fail if neither pattern is found.
this uses the string opening regex from the c-family highlighter to prevent
highlighting the rest of the file as a string on encountering the character
literal '"'
Generalize this option type, which is a timestamped list of
<line number>|<arbitrary string>. That way this type is not strongly
coupled with the flag-lines highlighter, and can be reused for other
use cases.
range-faces are now used to replace-range highlighters, where the string
part is not interpretted as a face but as a display line, so the name was
not relevant anymore.
`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
