@johnnyreilly Changes for adding auto fix as a flag. Let me know if I had missed anything.

Thanks for this! @piotr-oles what's your feeling on merging this? It's not a feature that I would use but clearly there's some demand out there for this.

I know you expressed reservations so I don't want to merge unless I know you're okay with this!

[piotr-oles]

Thank you @ajainarayanan for your work! I was afraid that it will add complexity to the plugin but looks like it doesn't. Please add an integration test for tslintAutoFix: true case and update README.md :)

[ajainarayanan]

@piotr-oles @johnnyreilly This is was a tricky change. Have taken an approach that shouldn't affect the other tests.

There is still one problem with should fix linting errors with tslintAutofix flag set to true test. It lints other files as well even though I am explicitly passing in the entry point. Don't know what I am missing but right now my brain is fried and can't think of a reason. Will update the pull request when I have sometime. If you happen to identify the reason as to why it updates other files please do point out and I will fix it.

UPDATE:
This is fixed now.

@ajainarayanan could you merge in the upstream changes please?

[ajainarayanan]

@johnnyreilly Have updated.

[ajainarayanan]

@piotr-oles @johnnyreilly Have updated the pull request. Can you give it another review.

[johnnyreilly]

Just merged in upstream changes @ajainarayanan.

@piotr-oles are you happy with the amends?

[ajainarayanan]

@johnnyreilly @piotr-oles I know its a little ridiculous to request some changes in an open source library and expect a release to happen right away but I am blocked by this change (or a new version of fork-ts-checker) to integrate prettier into my project.

Do we know tentatively when the pull request will be merged and a release will be cut? If any further changes are required please do let me know and I will make it.

[johnnyreilly]

Hey @ajainarayanan , sorry this is a bit of a frustration for you. From my perspective I'm fine for this to be merged and shipped now. Given @piotr-oles requested changes (which you've generously done!) I'd like him to confirm he's happy with the work rather than me merge directly.

If there's no response from him by the weekend then ping me again, maybe we can proceed without him. But that's not my preference.

Apologies for the delay; I understand the frustration.

[johnnyreilly]

Okay let's do this! Do you want to update the package.json and the CHANGELOG.md? Then I can cut a release.

[ajainarayanan]

@johnnyreilly Thanks! Have updated both. Could you give it a review?

[johnnyreilly]

Looks good - could you put the Default value of the field in the README.md please? Then we're good to go!

[piotr-oles]

Thank you for your work and sorry for blocking this PR. Like @johnnyreilly said, please add default value to the README.md and then we're ready for release :)

[ajainarayanan]

@piotr-oles @johnnyreilly Updated. Thanks for the review.

[johnnyreilly]

Thanks! Should be available shortly
