How to customise Eclipse for my own language?

Question

I have made a simple experimental language of my own. I want make Eclipse editor plugins or whatever I need to edit the programs for my language.

How do I begin with writing an Eclipse feature for my language?

Answer 1

How about trying Eclipse Xtext?
(That is if your language can follow an EBNF grammar)

Xtext is a framework for development of textual domain specific languages (DSLs).
Just describe your very own DSL using Xtext's simple EBNF grammar language and the generator will create a parser, an AST-meta model (implemented in EMF) as well as a full-featured Eclipse text editor from that.

The Framework integrates with technology from Eclipse Modeling such as EMF, GMF, M2T and parts of EMFT.
Development with Xtext is optimized for short turn-arounds, so that adding new features to an existing DSL is a matter of minutes. Still sophisticated programming languages can be implemented.
