Proposal. Ace input validation callback

[tsmirnov]

Hi, everyone.

We need small validation in ReactAce. We don't want to allow users submit code event with any kind of warnings. ReactAce show that warnings (like missing semicolon). As I know, there is no standard way to get the results of validation. (Issue #144) Am I right?

If so, I suggest to add a new callback prop onValidate. We can add listener on change annotations and invoke that callback. For example:

editor.getSession().on('changeAnnotation', function() {
  const annotations = editor.getSession().getAnnotations();
  onValidate(annotations);
});

If that functionality make sense, I could work on PR. What do you think?

@tsmirnov I think that sounds good. I would like to see a PR.

This will be live in 5.2.0 which is going live now.

Any documentation for this? I don't want to allow the user to submit if there are errors. @securingsincity

Was able to find it, I added a ref then this.editorRef.current.editor.session.$annotations was the path towards it.
