Gitlab CI - how to list directory that changes and put it in a pipeline variable-CodePudding

Is it possible to automatically detect the top-level directory that contains file that have changes in the commit, and add this to a variable that i can use in another stage ?

Let's say i have a project with :

folder1/file[1-3].txt
folder2/folder3/file4.txt

If the commit modify file1.txt, i would like to define a variable that is equal to "folder1".

   variables:
   - $MYVAR == "folder1"

If the commit modify file4.txt, i would like to define a variable that is equal to "folder2".

   variables:
   - $MYVAR == "folder2"

Modification to multiple file in different folder should not happen.

And then use that variable in another stage of the pipeline :

MEP:
  stage: deploy
  script:
    - echo $MYVAR

Would that be possible ? Thanks !

You can conditionally define variables with rules:variables: -- rules can use rules:changes: to determine if particular files changed.

myjob:
  variables:
    MY_VAR: "default value"

  rules:
    - changes:
        - folder1/file[1-3].txt
      variables:
        MY_VAR: folder1  # override MY_VAR when this rule matches
    - changes:
        - folder2/folder3/file4.txt
      variables:
        MY_VAR: folder2

Keep in mind only 1 rule matches for any given job/pipeline.
