I will continue to maintain tern.java but here my motivation to work a lot for typescript.java where the integration looks like tern.java: * ternjs is not very active today. It misses some features like support for multiple signature for methods. TypeScript is very very active, it supports multiple signature for methods, support JSX and more. * I'm limitated with JSDT Editor to add new features like override outline, generate comments (with type), refactoring. With typescript.java, I have now a custom TypeScript Editor which uses JSDT features for syntax coloration, matching bracket (lightweight editor) and which is very fast when you open a big file (because I don't need AST). More I will able to add refactor, outline, Ctrl+Shift+G by using tsserver without be blocked by JSDT AST and JSDT nature that I don't use it because I don't need Install Path, etc (Ctrl+Shift+G throws an error if your project has not JSDT nature for instance) * I would like to support Angular2. See https://github.com/angelozerr/angular2-eclipse which is based on typescript.java * TypeScript is improving the inference engine to use it for JavaScript (called Salsa). Visual Studio has switched to Salsa. typescript.java is able to support too JavaScript with Salsa. The inference engine is less powerfull than ternjs, but Micosoft guys are working a lot about this feature. * tsserver is very fast even with large project with big files. I try to implement typescript.java like VSCode to have the same fast features and it starts working well (compare to existing Eclipse TypeScript): completion, hover, hyperlink, validation are implemented and it is fast even with big project. I have used timeout in order to not freeze Eclipse when tsserver takes time. * The main problem with tsserver is that it is not extensible (like ternjs provide with custom plugin) but they are working hard for that. See demo with Angular2 at https://github.com/Microsoft/TypeScript/issues/6508 When it will available, typescript.java could provide that. I think more and more that tsserver is the very good solution for inference engine and for JavaScript too (not only TypeScript). My main goal is to provide the same powerful feature than WebStorm and VSCode want to do that too, tsserver is everytime improved for VSCode and I can benefit with this feature too:) Hope you will understand my motivation.
