Autofix

Automatically fix all software bugs.

Examples

Automatically fix bugs in the current directory:

autofix

Preview all the commands this would run, but don't actually do anything:

autofix --dry

Autofix bugs, commit fixes into separate branches, push branches to a GitHub remote:

autofix --branches --push=myremote

Autofix bugs in a GitHub repository:

autofix https://github.com/nodejs/node

Autofix bugs in a GitHub repository, commit fixes, and automatically send pull requests (requires hub):

autofix https://github.com/nodejs/node --pull-request

Try it online

Try it locally

If you have npm, you can already run autofix via npx:

npx autofix

Alternatively, can also install it like so:

npm install -g autofix

Command line options

autofix (DIRECTORY|REPOSITORY) [OPTIONS]

• DIRECTORY: Run autofix in a particular directory (defaults to .).
• REPOSITORY: Clone a Git repository, then run autofix in it.

OPTIONS:

• --dry: Simulate without actually running any fix commands
• --branches: Commit fixes of different types into different branches (e.g. autofix-codespell)
• --tiers=0,1,2: Choose which types of bugs should be autofixed (see details about tiers below)
• --verbose: Log additional information to the console (e.g. for troubleshooting autofix bugs)
• --push=REMOTE: Push fixes to a given GitHub remote (e.g. your GitHub username)
• --pull-request: Automatically open pull requests with pushed commits (requires hub, implies --push=origin if unspecified)
• --branch-suffix=SUFFIX: Add a common suffix to generated branch names (i.e. autofix-codespell-SUFFIX)
• --signoff: Use Git's --signoff (or -s) feature when creating commits
• --circle-ci: Run this autofix weekly on CircleCI (adds a .circleci/config.yml file)

Types of bugs that can be fixed

Tier 0 (no rework needed):

• Remove trailing whitespace (uses git, xargs and sed)
• Update pinned pyenv tool versions in Dockerfiles (requires pyenv)
• Update pinned nvm tool versions in Dockerfiles (requires nvm)
• Update pinned sdkman tool versions in Dockerfiles (requires sdkman)
• Update pinned rr versions in Dockerfiles
• Update some pinned Go module versions in Dockerfiles
• Update Git submodules

Tier 1 (some rework might be needed):

• Fix typos & spelling mistakes (requires codespell)

Tier 2 (experimental, use with caution):

• Fix C++ bugs with clang-tidy (requires clang-tidy)
• Fix Rust bugs with clippy (requires rust-clippy)

Tier 3 (you probably don't want to run these):

• TODO

Custom fixers

You can also implement your own fixers (similar to the ones found in the ./fixers/ directory) and commit them to your repository under a .autofix/fixers/ directory. Autofix will automatically pick them up; run them on your codebase; and commit new fixes when relevant.
