Hello. In response to my own feature requests (2993016, 2993022) I've written basic support for Erlang and Scheme into Geany. For Scheme, I hijacked the Lisp lexer and changed a few things, such as the names of the keyword configurations. There should probably be more subtle changes to accommodate differences in the languages. For Erlang, I used the existing Scintilla lexer and hooked it into Geany. The patch at
http://metasyntax.net/geany.diff can be applied to at least Subversion trunk r5303. Please let me know if this is welcome, and if so I'll put some time into refining the support, adding tag scanners, etc.
