Welcome

This repository is the official Trunk.io repo containing Trunk's integrations for linters, formatters, security tools, githooks, and default configs. By default, all Trunk users import this repo as a plugin, via this snippet in .trunk/trunk.yaml:

plugins:
  sources:
    - id: trunk
      uri: https://github.com/trunk-io/plugins
      ref: v1.5.0

This repo is open to contributions! See our contribution guidelines and join our slack community for help. If you're adding new tools, please see our testing guide as well!

Supported Trunk Actions

You can think of Trunk Actions as IFTTT for your repository. An action is a command that is run in reaction to a specified trigger. Triggers can be git-hooks, file modifications, time-based, or manually run. See docs for more details.

Enable trunk actions via:

trunk actions enable {action}

action	description
buf-gen	run buf on .proto file change
commitizen	enforce conventional commits and manage releases
commitlint	enforce conventional commit message for your local commits
go-mod-tidy	automatically tidy go.mod file
go-mod-tidy-vendor	automatically tidy and vendor go.mod file
git-blame-ignore-revs	automatically configure git to use .git-blame-ignore-revs
npm-check	check whether NPM installation is up to date
poetry-check, poetry-lock, poetry-export, poetry-install	hooks to enforce poetry configuration
yarn-check	check whether Yarn installation is up to date

Supported Tools

This repository also defines configuration for Trunk Tools, which provides hermetic management of different CLI tools. You can run trunk tools list to view all supported tools. Check out our docs.

Mission

Our goal is to make engineering faster, more efficient and dare we say - more fun. This repository will hopefully allow our community to share ideas on the best tools and best practices/workflows to make everyone's job of building code a little bit easier, a little bit faster, and maybe in the process - a little bit more fun. Read more about Trunk Check.

Additional Reference

Some linters provide built-in formatters or autofix options that don't always produce ideal outputs, especially in conjunction with other formatters. Trunk supports defining autofix options for these linters, but has their formatting turned off by default. An example of this is sqlfluff:

- name: sqlfluff
  files: [sql, sql-j2, dml, ddl]
  runtime: python
  package: sqlfluff
  direct_configs:
    - .sqlfluff
  commands:
    - name: lint
      run: sqlfluff lint ${target} --format json --dialect ansi --nofail
      output: sarif
      success_codes: [0]
      read_output_from: stdout
      parser:
        runtime: python
        run: ${plugin}/linters/sqlfluff/sqlfluff_to_sarif.py
    - name: fix
      run: sqlfluff fix ${target} --dialect ansi --disable-progress-bar --force
      output: rewrite
      formatter: true
      in_place: true
      success_codes: [0]
      enabled: false

The fix subcommand has enabled: false, so when you run trunk check enable sqlfluff, only the lint subcommand is enabled. To override this behavior, specify in your trunk.yaml:

lint:
  enabled:
    - sqlfluff@<version>:
        commands: [lint, fix]
