lint workflow (charmbracelet/log)

The lint workflow from charmbracelet/log, explained and optimized by Latchkey.

What it does

This is the lint workflow from the charmbracelet/log repository, a real project running GitHub Actions. It is shown here with attribution under its MIT license.

Below, Latchkey shows a faster, safer version produced by its optimization engine.

The workflow

name: lint
on:
  push:
  pull_request:

jobs:
  lint:
    uses: charmbracelet/meta/.github/workflows/lint.yml@main
    with:
      golangci_path: .golangci.yml

The same workflow, on Latchkey

Removes redundant runs and caps runaway jobs. Added and changed lines are highlighted.

name: lint
on:
  push:
  pull_request:
 
concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: true
 
jobs:
  lint:
    timeout-minutes: 30
    uses: charmbracelet/meta/.github/workflows/lint.yml@main
    with:
      golangci_path: .golangci.yml
 

What changed

• Cancel superseded runs when a branch or PR gets a newer push.
• Add a job timeout so a hung step cannot burn hours of runner time.

1 third-party action is referenced by a movable tag. Pin it to the commit SHA (Latchkey resolves and applies this automatically) so a repointed tag cannot change what runs.

This workflow runs 1 job per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
