incompatible with black v22.1.0 ?

black changed the return value of find_project_root() here: psf/black@521d1b8#diff-1a5882c84fe4b3f18199a3e021822c1ea4bdc3f86952ea450c4db15d9387c7c3

It's not a tuple :(

This will be fixed in #270.

[mayk0gan]

is there some workaround in the meanwhile?
I use darker's github action from the master branch (as suggested here)

[jedie]

I just pin black as a work-a-round:

darker = "*"
black = "==21.12b0"

[mayk0gan]

I just pin black as a work-a-round:

darker = "*"
black = "==21.12b0"

I'm not sure that it would work with the github action. Do you put it in pyproject.yaml?

[mayk0gan]

The github action still doesn't work on master though:

@mayk0gan I think it still clones the last release when building the image even though the action "recipe" comes from master. Should be fixed when we release 1.4.0.

[foxwhite25]

It still failed with a @1.4.0 to specify 1.4.0, thats odd.

@foxwhite25 the action has a version setting that defaults to 1.3.2 you probably need to explicitly set that to 1.4.0 https://github.com/akaihola/darker/blob/master/action.yml#L18

[akaihola]

Thanks @mayk0gan @foxwhite25 @jenshnielsen, I'll look into this soon. Is this the same as #260?

[jenshnielsen]

I have set it with the following config which seems to work fine.
But note that I need to set the version twice

name: Lint with Darker

 on: [push, pull_request]

 jobs:
   lint-with-darker:
     runs-on: ubuntu-latest
     steps:
       - uses: actions/checkout@v2
         with:
           fetch-depth: 0
       - uses: akaihola/[email protected]
         with:
           options: "--check --diff -r origin/master -i"
           version: "1.4.0"

[MatthijsBurgh]

As mentioned in @260. The action file still sets 1.3.2 as the darker version to be used. Even in master and the 1.4.0 tag. So a manual override is still needed at the moment. But this should be fixed in the action file.

[jedie]

I made this:

    - uses: actions/checkout@v2
      with:
        fetch-depth: 0
    - name: 'fetch master'
      run: |
        git fetch origin master

https://github.com/boxine/django-huey-monitor/blob/49d5b214afa1f0af0b8e7fb9b24f92327c8ad5be/.github/workflows/pythonapp.yml#L24-L29

to always compare with master ;)

[jenshnielsen]

@jedie I originally started with --check --diff -r master but realized that using --check --diff -r origin/master I did not need to explicitly fetch the master branch

[jedie]

Hm. Interesting: I use revision = "origin/master..." in pyproject.toml: https://github.com/boxine/django-huey-monitor/blob/49d5b214afa1f0af0b8e7fb9b24f92327c8ad5be/pyproject.toml#L74

Think the fetch is needed. But let's try it: boxine/django-huey-monitor#85 https://github.com/boxine/django-huey-monitor/actions/runs/1828419972
