Gitlab Support

[btd1337]

Is it possible to add GitLab CI support?

I would also like to see this.

Using eslint 8 I have added plugin plugin:diff/ci to .eslintrc.js.

I have tried to add to my .gitlab-ci.yml file

variables:
    ESLINT_PLUGIN_DIFF_COMMIT: $CI_COMMIT_SHA

But the pipeline fails with the error

Error: Failed to load plugin 'diff' declared in '.eslintrc.js': Command failed: git diff --diff-algorithm=histogram --diff-filter=ACM --find-renames=100% --name-only --no-ext-diff --relative origin/4a7f61a60b7832978759985188381440647524b4 --

It would seem that if we can find the correct predefined variables and replace $CI_COMMIT_SHA with the correct variable it should work.

https://docs.gitlab.com/ee/ci/variables/predefined_variables.html

Also tried this variable but it did not work:
CI_MERGE_REQUEST_DIFF_BASE_SHA - The base SHA of the merge request diff.

When I used $CI_COMMIT_SHORT_SHA I get the error:

Error: Failed to load plugin 'diff' declared in '.eslintrc.js': Command failed: git fetch --quiet origin a8efa4b3
