"Variable" set for gitea action not accessible in job

[bf]

Description

When setting a custom variable for gitea action in "repo -> settings -> actions -> variables -> "Variables Management"" it is not accessible in the job.

I have tried ${{VARNAME}}, ${{github.VARNAME}}, ${{env.VARNAME}}, and ${{gitea.VARNAME}}.

act_runner is on a different server.

expression 'format('echo {0} | docker login --password-stdin --username {1} myregistry.com', secrets.DOCKER_PASSWORD, gitea.DOCKER_USERNAME)' evaluated to '%!t(string=echo *** | docker login --password-stdin --username  myregistry.com)'

"secrets" work fine via ${{secrets.VARNAME}} but variables dont

[bf]

${{variables.VARNAME}} doesn't work either:

Unable to interpolate expression 'format('echo {0} | docker login --password-stdin --username {1} myrepository.com', secrets.DOCKER_PASSWORD, variables.DOCKER_USERNAME)': Unavailable context: variables

[bf]

I see gitea developers themselves use "secrets" to store the DOCKER_USERNAME, because it doesn't seem to work otherways. Why isn't there a disclaimer in "Variables Management" UI?

Finally found #24724

@sillyguodong can you please improve gitea documentation so that it is clear ${{vars.VARNAME}} needs to be used? It should be said both in the UI at org/reponame/settings/actions/variables and in the gitea docs.

[bf]

Not sure why for "Variables" the abbreviation is ${{vars.VARNAME}} but for "Secrets" the abbreviation is ${{secrets.VARNAME}}. It should be the same style, either full or abbreviated.

[sillyguodong]

Not sure why for "Variables" the abbreviation is ${{vars.VARNAME}}.

The workflow syntax of Gitea Actions is consistent with Github(see https://docs.github.com/en/actions/learn-github-actions/contexts#vars-context).

@sillyguodong can you please improve gitea documentation

Sure
