I was working on integrating a language with a "programmers editor" <name omitted to protect the guilty> and asked how to extend the editor to indent a new language. The response was "it should already support all C/Java like languages with the configuration format." My response "this isn't a C-like language". The community response "Uh, I guess write a plugin that installs a hook on the carraige-return key and manually position the cursor?" It blew my mind that anything billed as a programmer's editor couldn't be customized for doing this already...

The syntax compilers use to indicate filename and error location are similar among compilers, and generally quite unambiguous anyway, so in many cases no configuration is needed. A small list of regexes built in to the editor is enough.

To be fair, I dont actually know what percentage of editors have that feature, my impression is just that many people arent aware of the idea. Maybe Im wrong though.
