# Branch Protection and Pre-Merge Checks
|
|
|
|
This repository uses GitHub Actions to ensure code quality before merging to `main` or `master` branches.
|
|
|
|
## Required Checks
|
|
|
|
### Shell Script Linting
|
|
|
|
The `Shell Script Linting` workflow automatically runs on:
|
|
|
|
- Pull requests targeting `main` or `master` branches (including from forks)
|
|
- Direct pushes to `main` or `master` branches
|
|
|
|
This workflow checks:
|
|
|
|
- Shell script syntax with `shellcheck`
|
|
- Code formatting with `shfmt` (2-space indentation, no tabs)
|
|
- Optional checks: `checkbashisms`, syntax validation
|
|
|
|
## Enabling Branch Protection
|
|
|
|
To make the shell linting check **required** before merging PRs, follow these steps:
|
|
|
|
1. Go to repository **Settings** → **Branches**
|
|
2. Click **Add rule** or edit existing rule for `main`/`master`
|
|
3. Configure the following settings:
|
|
- ✅ **Require a pull request before merging**
|
|
- ✅ **Require status checks to pass before merging**
|
|
- Search for and select: `Lint Shell Scripts`
|
|
- ✅ **Require branches to be up to date before merging** (recommended)
|
|
- ✅ **Do not allow bypassing the above settings** (recommended)
|
|
4. Click **Create** or **Save changes**
|
|
|
|
## Running Checks Locally
|
|
|
|
Before pushing changes, run the linting script locally to catch issues early:
|
|
|
|
```bash
|
|
bash scripts/meta/shell_check.sh
|
|
```
|
|
|
|
This will:
|
|
|
|
- Install required linters on Arch Linux (if needed)
|
|
- Check all shell scripts in the repository
|
|
- Report any formatting or syntax issues
|
|
|
|
To auto-fix formatting issues:
|
|
|
|
```bash
|
|
# Install shfmt if not already installed
|
|
# On Arch: sudo pacman -S shfmt
|
|
# Or download from: https://github.com/mvdan/sh/releases
|
|
|
|
# Fix formatting in-place
|
|
find . -name "*.sh" -type f | xargs shfmt -w -i 2 -ci -sr -s
|
|
```
|
|
|
|
## What Gets Checked
|
|
|
|
The workflow validates shell scripts with these extensions or shebangs:
|
|
|
|
- `*.sh`, `*.bash`, `*.zsh` files
|
|
- Executable files with shell shebangs (`#!/bin/bash`, `#!/bin/sh`, etc.)
|
|
|
|
## Troubleshooting
|
|
|
|
If the check fails on your PR:
|
|
|
|
1. Review the workflow logs to see which files failed
|
|
2. Run `bash scripts/meta/shell_check.sh` locally to reproduce
|
|
3. Fix the issues (usually formatting with `shfmt -w -i 2 -ci -sr -s`)
|
|
4. Commit and push the fixes
|
|
|
|
The workflow will automatically re-run on new commits to the PR.
