Eclipse tm4e - TextMate and language-configuration support for Java and in Eclipse IDE

TM4E brings Java API to tokenize textual documents according to TextMate grammars with an Eclipse IDE client that can do syntax highlighting according to this tokenization; and Eclipse IDE client for VSCode Language Configuration to support matching bracket, auto close, on enter support.

tm4e is an official Eclipse.org project so it conforms to typical Eclipse.org requirements and guarantees.
