add failing test for check-typecast

[despairblue]

The formatter add no space after a typecast at the moment, it actually removes it, which is at odds with the tslint:recommended rules.

With some help I can probably fix this my self, I know that something like this needs to be added here

            } else if (value === "check-typecast") {
              formatSettings.insertSpaceAfterTypeCast = true;
            }

But where does the actual formatting happen?

[despairblue]

Ok, so this is using the formatter in typescript and there are only a limited amount of options that can be set. So I guess there is no way to do this right now. Am I correct?

Yes. that's right.
but newest tsc has a insertSpaceAfterTypeAssertion field I found. I'll try it.

just released v5.1.0. try it out!

@vvakame thanks, you awesome!

It does work if I add the insertSpaceAfterTypeAssertion setting to tsfmt.json or "whitespace": [true, "check-typecast" ] to the my tslint.json, but if I don't it does not pick it up from the recomended rules from the tslint file.

Using this tslint.json the test still fails:

{
  "extends": "tslint:recommended"
}

oh... extends of tslint does not supported yet...
