There is a Replacement parameter to automatically fix issues, which is very useful for gofumpt.

If I'm not mistaken, gofumpt provides only as a public function a way to get the gofumpt-ed version of the file (as a []byte).
With Replacement you mean I should include the gofumpt-ed version of the whole file in the issue?

@tetafro Am I correct?

gofumpt provides only as a public function a way to get the gofumpt-ed version of the file

Yeah, sorry, I didn't think of it.

With Replacement you mean I should include the gofumpt-ed version of the whole file in the issue?

I'm not sure if it's a right thing to do. Someone more experienced with golangci-lint architecture should answer.

Anyway, if there's no easy way to do this, just skip my first comment.

Can you please add test to tests/testdata?

If there is no autofix, you should remove this line

@tetafro I've just added a test. Just something to mention, previously I was setting the error line to 0. I wanted to change it to line 1 but in the test file, I can't do this:

// ERROR "File is not `gofumpt`-ed"
//args: -Egofumpt
package testdata

Hence, I set it to the last line number and it's working correctly.

tetafro · 2020-06-12T19:23:08Z

Hence, I set it to the last line number and it's working correctly.

I've looked how gofmt linter is implemented. Seems like the right thing to do here is to re-use diff code from gofmt linter.

But I think using the last line is ok for the first iteration. Maybe just add TODO in the code.

Is it really necessary? You've already read the file into input. Just use strings.Count.

Thanks! This looks good to me.

Thanks! This looks good to me.

@tetafro Any chance to get it merged then? :)

Hi, how's the doc updated once a new linter is merged?

teivah · 2020-06-22T07:47:18Z

@tetafro Just out of curiosity, when do you plan roughly to make a new release?
Thanks
