Tools for conditional azure pipeline execution. Currently only supports run triggerd by github pull request.
The script src/cli.mjs (could be invoked with npx) will check if current pipeline run passes following checks and the output pipeline variable skipsubsequent will be set to True or False according to checks' results.
The script should be put in a seperated job / stage and following jobs / stages could use the output variable to judge if it should be skipped.
stages:
- stage: Filter
jobs:
- job: Check
steps:
- task: NodeTool@0
inputs:
versionSpec: '16.x'
- script: npm install npm@latest -g
displayName: Update npm to use npx with github url
- script: npx github:microsoft/azure-pipeline-filter
env:
FILTER_GITHUBPAT: $(filter.githubPAT)
name: execution
displayName: Execution
- stage: Main
dependsOn: Check
# dependencies.$(StageName).outputs['$(JobName).$(TaskName).$(VariableName)']
condition: and(succeeded(), ne(dependencies.Filter.outputs['Check.execution.skipsubsequent'], 'true'))
jobs:
- job: Main
steps:
- script: echo end
displayName: 'Run main test'If pipeline run is not triggered by github pull request, skipsubsequent will be set to False, and the script will exit.
Otherwise, run following checks.
Check if any modified files matches the glob patterns provided by pipeline variable filter.modified.globs.
Due to github rest api's limitation, skipsubsequent will be set to False when changed file count > 3000
If true, skipsubsequent will be set to False, and the script will exit.
Otherwise, run following checks.
The script will try to find the task list under the heading provided by pipeline variable filter.prbody.heading from the pull request markdown body.
If the task list is not found, skipsubsequent will be set to True.
If ANY selected options match provided index (filter.prbody.optionIndex) / value (filter.prbody.optionValue), skipsubsequent will be set to False.
Otherwise, skipsubsequent will be set to True.
Github personal access token used to access the pull request info. Could be ignored if the repo is public.
It should be a secret variable and need to be exposed to the script explicitly.
- script: node src/main.mjs
env:
FILTER_GITHUBPAT: $(filter.githubPAT)Heading used by pull request body check to locate the task list.
Option index (start from 0) / value to be compared with selected options in the located task list.
Comma seperated glob patterns. See multimatch's doc for more information.
Output variable. If following tests need to be skipped, it will be set to true.
Please refer to azure pipeline's doc for more information.
