dna_scripts

The DNA layer for the node scripts a repo automates its workflow with — deterministic given local git and file system state, no GitHub API calls.

Guides

• dna/doc/guides/scripts-guide.md — what belongs here, what does not, and how to add a script

Skills

• /scripts — checks every script parses, every import resolves, and reports duplicated logic that should be a shared function

Scripts

• dna/scripts/functions/colors.js — ANSI colors for console output
• dna/scripts/functions/current-branch.js — the current git branch
• dna/scripts/functions/directories.js — the script's own directory
• dna/scripts/functions/get-version.js — the version from package.json
• dna/scripts/functions/is-clean-repo.js — whether main is checked out, clean and in sync with origin/main
• dna/scripts/functions/is-main-up-to-date.js — whether local main matches origin/main
• dna/scripts/functions/run-command.js — runs a shell command, logs and returns its output
• dna/scripts/functions/sync-folders.js — recursively copies one folder into another
• dna/scripts/functions/get-repo-urls.js — lists a GitHub organization's repository URLs via gh
• dna/scripts/functions/pull-request-url.js — the URL of the current branch's pull request via gh
• dna/scripts/delete-feature-branch.js — deletes the current feature branch locally and on the remote once it is merged
• dna/scripts/rename-class.js — renames every occurrence of a class and file name across the repo
• dna/scripts/setup-github-repo.js — applies the branch protection rules a new repo needs
• dna/scripts/wait-for-pr.js — waits for the current pull request to merge

Layers

Orthogonal: this layer carries only its own topic and is combined with other layers by the consuming repo.

Variables

• dnaCopyrightHolder — the name in the license header of every file

Usage

Declare it as a dev-dependency and initialize once:

pnpm add -D @ggdna/dna-scripts   # TypeScript projects
dart pub add dev:dna_scripts     # Dart projects
helix init

The placed test instantiates and verifies the DNA on every test run.

Development

The dna/ folder is hand-authored source and is never generated. The repo instantiates its own DNA — run dart test after changes; commit first, a file the DNA would overwrite must not carry uncommitted work.
