I have no experience with the git-workflows: If I merge this into the master of my fork (return42/searx) on github .. will it also create PRs on my my fork? .. I guess .. if so .. can we set a condition in the git-workflow, that the workflow is active only on repository searx/searx?

[dalf]

I have updated the PR: the workflow will return only if the DATA_PR_TOKEN secret is defined (without this change, the workflow runs and fails to create the PR).

DATA_PR_TOKEN is a personal access tokens.

LGTM ..

OT: just a question of mine

DATA_PR_TOKEN is a personal access tokens.

Tried to find, where I can set it using https://docs.github.com/en/github/developing-online-with-codespaces/managing-encrypted-secrets-for-codespaces .. but cant find 'Codespaces' what is documented there ... do I need a special contract to set such tokens?

[dalf]

To get the token: your profile, Settings, Developer settings tab, Personal access tokens tab.
To set the secret: in your fork, go into Settings, then the "Secrets" tab, then the "New repository secret".

Dump question, is this git-workflow inactive?

When I make useragents.update I got ...

modified   searx/data/useragents.json

What I mean; I can't see that this PR does anything .. I'm wrong? .. Is there a place, where can we monitor the tasks from

searx/.github/workflows/data-update.yml

Lines 3 to 4 in ab87398

	schedule:
	- cron: "37 13 * * 0"

I guess the notation is what we know from unix cron entries.. right?

if: env.DATA_PR_TOKEN != null

should be

I see! ... thanks for the link .. I should have more time to learn more about git-workflows.

If you have time do you like to fix it ..

Seems that .github/workflows/data-update.yml had another issue: https://github.com/searx/searx/actions/runs/561157462/workflow and it seems you did already fixed it 50bde93 ?
