A truly awesome programmer's text editor, Vim can do just about anything, and always in a smaller number of keystrokes than any editor can provide. It also has an awesomely flexible scripting system for plugins, syntax highlighting, indentation rules, and more. I've written some code to go along with Vim, so here are some things.
Based on the GNU Make-oriented one which is distributed with Vim, this adds support for marking directives, targets, and features specific to BSD Make. Features include:
:[HELUQRT]) and
replacement (:[SC]/.../.../[1g])..DEFAULT.Syntax support for the JVM Lisp language Clojure. Derived from Meikel Brandmeyer's Vim Clojure. Basically I extracted the syntax file and made some changes so it doesn't rely on external scripts.
Adds custom SQL syntax support for Derby databases.
Enhances C-within-Scheme syntax highlighting, essentially duplicating the functionality which
exists when using Chicken for Gambit. Set the variable scheme_is_gambit either in
the buffer or globally to enact highlighting within c-declare forms.
I'm the official Tcl syntax maintainer, so the stable version is available on the Vim FTP site in the runtime directory. The current CVS version and its history are available on this site; the official version has a CVS version number in the comments at the top. Also please see the page tracking progress on this syntax support.
Based on the official Texinfo syntax, enhanced with the ability to highlight verbatim blocks ala LaTeX mode.
