Xtext can build full-featured text editors for both general-purpose and domain-specific languages. In the background it uses the LL(*) parser generator of ANTLR, allowing to cover a wide range of syntaxes. Xtext editors have already been implemented for JavaScript, VHDL, Xtend, and many other languages.
