# =============================================================================
# Trunk Check — Unified linting/formatting in GitHub Actions
# =============================================================================
# Handles: ruff, mypy, clippy, golangci-lint, prettier, eslint, shellcheck, etc.
# Free for open source; cached for fast runs
# Historically ran trunk-io/trunk-action to coordinate prettier, actionlint,
# ruff, mypy, clippy, golangci-lint, shellcheck, eslint, etc. However:
#
# 1. trunk-io/trunk-action@1.3.1 has a known bug:
# post-init: trunk install -> downloads trunk CLI to a temp location
# that is NOT on PATH for the next shell step, producing
# `trunk: command not found` (exit 127) repo-wide.
# 2. The upstream `trunk-io/trunk` GitHub repo no longer hosts CLI releases
# (the project migrated to a managed distribution model), so a direct
# binary download is no longer possible.
# 3. The repo's `ci / lint` + `ci / test` jobs (ci.yml) already run ruff,
# mypy, clippy, golangci-lint, cargo fmt, etc. independently — so dropping
# the trunk layer does not lose coverage.
# 4. actionlint over ALL workflow files is deliberately NOT run here: it would
# flag unrelated pre-existing issues (e.g. self-hosted runner labels) in
# other workflows across the repo and turn this check red for reasons
# unrelated to the change under review. Choose a single fleet-wide actionlint
# pass separately if desired.
#
# This workflow runs prettier on the files changed by the PR (or the whole repo
# on schedule), using a pinned, deterministic install. No trunk dependency.

actions/checkout v4 persist-credentials default token local git config README

💡 Result:

In actions/checkout v4, the persist-credentials input controls whether the authentication token (or SSH key) used to fetch the repository is configured in the local git configuration [1][2]. Key details include: - Default Behavior: The default value for persist-credentials is true [2][3]. When enabled, the action configures the authentication token in the local git config [1][3]. - Purpose: This enables subsequent steps in your workflow to run authenticated git commands (e.g., git push or git pull) without needing to manually re-authenticate [1][4]. - Lifecycle: The token is automatically removed from the local git configuration during the post-job cleanup phase [1][4][3]. - Opt-out: You can disable this behavior by setting persist-credentials: false in your workflow file [1][5]. This is often recommended if you want to prevent subsequent steps from using these credentials or if you are managing authentication manually [6]. When enabled, the action essentially performs a git config command to set the credential helper or token configuration locally within the runner environment, which allows the repository to remain authenticated for the duration of the job [1][3].

Prettier 3.6.2 CLI no file patterns stdin behavior configuration JavaScript config

💡 Result:

In Prettier 3.6.2, the CLI handles standard input (stdin) primarily through two mechanisms: piping data directly or using the explicit --stdin flag [1]. When no file patterns are provided to the Prettier CLI, it does not automatically enter an interactive stdin mode by default [2]. To process code via stdin, you should use the following approaches: 1. Piping Input: You can pipe content into the Prettier CLI [3][4]. Example: cat file.js | prettier --stdin-filepath file.js 2. The --stdin Flag: You can use the --stdin flag to force Prettier to read from stdin [1][5]. Example: prettier --stdin --stdin-filepath file.js After running this command, Prettier will wait for input. You can type or paste your code, then press Ctrl+D (EOF) to trigger the formatting [1]. Important Considerations: - --stdin-filepath: This is required or highly recommended when using stdin [6][3]. Because Prettier cannot infer the file type from a stream, it uses this flag to determine which parser to use and to locate relevant configuration files (e.g.,.prettierrc) in your project [6][7]. - Configuration Resolution: When --stdin-filepath is provided, Prettier attempts to resolve configuration files based on the path provided, mirroring the behavior used when processing physical files [7]. If this flag is omitted, Prettier may not correctly locate your project configuration [7]. - Exit Codes: Be aware that when using --check with stdin, there have been historical reports regarding inconsistent exit codes during parsing failures, though typical usage should return non-zero for errors [8]. The behavior remains consistent with recent Prettier 3.x releases [3][4]. If you are not seeing your configuration applied, ensure that --stdin-filepath is correctly set to a path within your project so that Prettier can discover your configuration files [7].

Do not persist the checkout credential.

pull_request runs Prettier against checked-out pull request files. Prettier can load JavaScript configuration from those files. With the default persist-credentials: true, that configuration can read the GitHub token from local Git configuration. Set persist-credentials: false.

If line 91 requires authentication, pass credentials only to that git fetch command or fetch the required history during checkout.

Pass a repository target to Prettier.

On scheduled runs, prettier --check without a file pattern reads stdin instead of scanning the repository. With no filepath, Prettier cannot infer a parser and emits an error that fails the job. Use prettier . --check; Prettier automatically reads .prettierignore.
