https://code.forgejo.org/forgejo/forgejo-actions-feature-requests/issues/71 requires partial implementation in runner, and partial in Forgejo; this is the Forgejo implementation.
Allows for the definition of dynamic job matrixes in Forgejo Actions, where an earlier job provides and output that is used in `strategy.matrix` for a later job that requires it. For example, adapted from the GitHub Actions example for this feature:
```yaml
name: shared matrix
on:
push:
workflow_dispatch:
jobs:
define-matrix:
runs-on: docker
outputs:
colors: ${{ steps.colors.outputs.colors }}
steps:
- name: Define Colors
id: colors
run: |
echo 'colors=["red", "green", "blue"]' >> "$GITHUB_OUTPUT"
produce-artifacts:
runs-on: docker
needs: define-matrix
strategy:
matrix:
color: ${{ fromJSON(needs.define-matrix.outputs.colors) }}
steps:
- name: Define Color
env:
color: ${{ matrix.color }}
run: |
echo "$color" > color
- name: Produce Artifact
uses: https://data.forgejo.org/forgejo/upload-artifact@v4
with:
name: ${{ matrix.color }}
path: color
consume-artifacts:
runs-on: docker
needs:
- define-matrix
- produce-artifacts
strategy:
matrix:
color: ${{ fromJSON(needs.define-matrix.outputs.colors) }}
steps:
- name: Retrieve Artifact
uses: https://data.forgejo.org/forgejo/download-artifact@v4
with:
name: ${{ matrix.color }}
- name: Report Color
run: |
cat color
```
