Currently, inserting a newline after a ruby method will incorrectly
cause the following line to repeat the method header. This commit
adds a test case to illustrate the bug.
Various places in Kakoune code used to modify selections so that
cursors would not lie on an end of line. Remove those to increase
Kakoune's consistency and simplicity.
Now that end of lines are highlighted separately, they should not
be handled specially in most commands.
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.
