syntaxes: remove quotes from each syntax name, and color it differently The different color will make the name stand out, as it should, instead of looking the same as all the regex strings. 2018-02-07 13:25:46 +03:00			`syntax autoconf "\.(ac\|m4)$"`
new feature: comment/uncomment current line or selected lines This allows for commenting or uncommenting a line or a bunch of lines with a single keystroke (default binding: M-3). The characters used for commenting/uncommenting are specified by the active syntax file.

Expanding the autoconf syntax a little, by handling .m4 files too, adding the "elif" keyword, handling dnl comments better, and marking trailing whitespace.

syntaxes: remove some superfluous outer parentheses from regexes Also, standardize some comments, condense a few regexes, add some word-edge anchors, and remove some superfluous backslashes. 2020-04-21 13:47:08 +03:00			`color yellow "=\|!=\|&&\|\\|\\|"`

syntaxes: use one regex for coloring quoted strings, to avoid overlap Quoted strings cannot start within another quoted string and end after that other string has ended. Therefore single-quoted and double-quoted strings should (as much as possible) be colorized by a single rule, so that overlapping colorations are avoided. (This also fixes a double typo in the PHP syntax (\. --> \\.) that has been there since the PHP syntax was added in 2008, commit 90ee8ee4.) This fixes https://savannah.gnu.org/bugs/?61387. Bug existed since each of these syntaxes was introduced, the oldest ones around 2006, a few others around 2015. The one that got it right was the Lua syntax from 2011. 2021-10-26 13:27:15 +03:00			`color red ""[^"]"\|'[^']'"`

syntaxes: replace [[:space:]] with [[:blank:]] to exclude carriage return In many places a carriage return is not valid whitespace and should thus not be colored as such. In some of these places a vertical tab or form feed is maybe valid whitespace, but it would be ugly or even wrong to color them because they are not part of the subsequent comment or keyword.
