Scite Auto Complete Any Language

wiki

What constitutes an identifier is determined by the list of patterns in IDENTIFIER_PATTERNS. This example allows identifiers to include dots (e.g. to suggest a whole "object.member.property" string) and dashes, (e.g. "lisp-or-css-identifier").

This script may not behave well if you have auto-completion enabled in SciTE properties. (It would probably be straightforward to make it disable itself for certain file types.)

Unfortunately the AutoCShow() function seems not to work if keywords contain characters like '.'...
