name: 'Nix Flake Outputs Size Report'
author: Jalil David Salamé Messina
description: |
Use `nix path-info` to query the size of flake outputs and produce a markdown
report.
You can post this report as a comment to the PR associated with the current
branch and/or export the report as a JSON artifact.
Requires `nix`, `jq`, `curl`, `sed`, `gunzip`, `tar` and `coreutils` to be in
the runner's path.
Usage:
```yaml
- name: Generate size report
uses: https://git.salame.cl/jalil/nix-flake-outputs-size@main
with: # Default values
comment-on-pr: 'true'
generate-artifact: 'false'
artifact-name: 'size-report.md'
# If you want to enable comparisons set this to true
do-comparison: 'false'
job-name: '' # required if do-comparison is true
# This is the branch that will be compared against
base-branch: ${{ github.base_ref }} # or default branch if missing
```
inputs:
comment-on-pr:
description: |
Comment the report on the PR associated with the current branch.
This is a no-op in case no PR is associated with the current branch.
default: 'true'
system:
description: |
The nix system name to query the packages of (e.g. x86_64-linux)
# Generate workflow artifact
generate-artifact:
description: Export the generated markdown document as a workflow artifact.
default: 'false'
artifact-name:
description: The name of the generated artifact.
default: report.json
# Comparison Report (comment only)
do-comparison:
description: |
When commenting on the PR compare the results with those in the base branch.
This is a no-op when `comment-on-pr: false`.
It requires `job-name` to be set.
default: 'false'
job-name:
description: |
The name of the job running this action. If not set, no comparisons can
be made.
default: ''
base-branch:
description: |
The name of the base branch, defaults to `github.base_ref` if present
(when triggered by a `pull_request`). Otherwise defaults to the repo's
default branch. Set in case you want to override this behaviour.
It will try to download the generated artifact from this branch so make
sure `generate-artifacte: true` when the workflow is running on that
branch.
default: ${{ github.base_ref }}
