  1. Code Quality
  2. Linters

Run Linters

The main commands when running trunk from the command line are:

trunk check       # runs the universal linter on all applicable files
trunk fmt         # runs all the enabled formatters and auto-applies changes

You can always find this list using trunk check --help.

Trunk is git-aware. When you run trunk check it will only run on files you've modified according to git. To run on a sampling in your repo, run: trunk check --sample 5

check

trunk check runs linters & formatters on your changed files, prompting you to apply fixes. Without additional args, trunk check will run all applicable linters on all files changed in the current branch.

fmt

Run all applicable formatters as configured in trunk.yaml. trunk fmt is short-hand for running trunk check with a --fix --filter set to all formatters enabled in your repository.

Options
