An Open-Source ( Scintilla-based) editor for Window or Linux. It now includes built-in support for D since Scintilla added a D parser.
The official SciTE download from scintilla.org didn't used to include support for D syntax, a version that supports D was only available at http://wiki.dprogramming.com/SciTE/HomePage. It should properly handle all D's features, such as nesting comments, different string types with prefixes and suffixes, etc - Chris (based on NG:digitalmars.D.announce/2084)
In cpp.properties you can add "api.<filepattern>=<file.api>", e.g.
api.*.d=d.apiand put prototypes in the api file. If you compile a nice api file, please post it (to wiki if you like).
