Support Code Format on Save

[nhnb]

The editor shall support save actions, especially the possibility to apply code formatting automatically.

This would better being enabled directly in LSP4E (as it could be implemented exactly the same way for all language servers).

How would such formatting be defined? Are you using editorconfig or something else? Have you tried adding a project build action that invokes your formatter on save?

[nhnb]

@mickaelistria It is already possible to invoke code formatting manual via short cut or menu command. As far as I understand it, the code formatting will be done via language server. I have not tried to add a build-action because I don't know how to call the language server.

@mickaelistria any chance of this being implemented?

I personally don't plan to work on it anytime soon, but would review oncoming pull requests with high priority.

Please, consider implementing this feature. I was using CodeMix for JSX files. Due to end of life, I searched for alternatives. Wild Web Developer seems to be the only one in the Eclipse Marketplace, but it does not have formatting as a save action. Everytime I save a file, I have to press Ctrl+Shift+F first. It is quite annoying and if I forget to do it, I might commit code uncorrectly formatted. I guess many developers are in the same situation.

@s3curitybug please consider contributing a patch for that.
