Pre-Commit Installation

Before starting development work on this repo, pre-commit must be installed.

In order to do so, run the command make init-pre-commit from the repository root.

Once this is done, the following checks will be performed on every commit to the repo and must pass before the commit is allowed:

1. Basic checks

• check-yaml - Checks YAML files for errors
• check-merge-conflict - Ensures there are no merge conflict markers
• end-of-file-fixer - Adds a newline to end of files
• trailing-whitespace - Trims trailing whitespace
• no-commit-to-branch - Ensures commits are not made directly to main

2. Go-specific checks

• go-fmt - Runs gofmt
• go-imports - Runs goimports
• golangci-lint - run golangci-lint run ./...
• go-critic - run gocritic check ./...
• go-build - run go build
• go-mod-tidy - run go mod tidy -v

3. Detect Secrets

Will detect any potential secrets or sensitive information before allowing a commit.

• Test variables that may resemble secrets (random hex strings, etc.) should be prefixed with test_
• The inline comment pragma: allowlist secret may be added to a line to force acceptance of a false positive
