Git Collector

Git Collector is a command-line tool that lets you interactively browse a GitHub repository, select files or directories, and collect their contents into a Markdown data file. It's useful for gathering code snippets, configuration files, or other resources from a repository for offline use or documentation, especially for sharing with an AI assistant.

Features

• Navigate a repository tree fetched from GitHub
• Preview file contents in the terminal
• Select or deselect individual files or entire directories
• Save selected contents to a structured Markdown file
• Update an existing data file with the latest repository contents

Prerequisites

• Node.js (>= 14)
• One of the following package managers:
  • pnpm (Recommended)
  • npm
  • Yarn

Installation

From npm registry

Install the published package globally with pnpm:

pnpm add -g git-collector
# or with npm:
npm install --global git-collector
# or with Yarn:
yarn global add git-collector

After installation, you can invoke:

git-collector <dest.md>

From source

First, clone this repository and install dependencies:

git clone <repo-url>
cd git-collector
# Install dependencies (choose one)
pnpm install
# or
npm install
# or
yarn install

Install Globally (optional)

To make the git-collector command available system-wide:

pnpm

pnpm link --global

npm

npm link

Yarn

yarn link

Once linked, you can run the command globally:

git-collector <dest.md>

Usage

git-collector [--update] [--force] <destination>

• <destination>: Path to the Markdown data file to create or update. In update mode, this may instead be a directory containing Git Collector data files.
• --update: Update files and then exit (no interactive UX), if the destination exists:
  • When it's a data file, refresh that single file with the latest selections.
  • When it's a directory, scan that directory (no subdirectories) for files marked as Git Collector data files (identified by a first line of # Git Collector Data) and update each in turn.
• --force, -f: When used with --update, always rewrite the data file(s), updating timestamps even if there are no content changes.

Create a New Data File

git-collector data.md

• You'll be prompted to enter a GitHub repository URL (e.g., https://github.com/user/repo).
• Use the following keys to interact:
  • <↑>/<↓>: Navigate the file tree
  • <←>/<→>: Expand or collapse directories
  • <PgUp>/<PgDn>: Page-scroll
  • <space>: Select or deselect a file or directory
  • <enter>: Preview the selected file
  • <tab>: Switch focus between tree and preview
  • <s>: Save selections to the data file
  • <x>: Save and exit
  • <q>: Quit without saving
  • <w>: Toggle word-wrap in preview (when focused on preview)

Update an Existing Data File

git-collector --update data.md

• Reloads the URL and file list from data.md and fetches current contents, reporting how many files were updated or removed, without invoking the interactive UI.
• This is useful for integrating with other tools or scripts, or just as a quick way to refresh the data file.
• The --force option can be used to rewrite the data file even if there are no content changes.

Update a Directory of Data Files

git-collector --update data/

• Scans the specified directory for files marked as Git Collector data files (identified by a first line of # Git Collector Data) and updates each in turn.
• This is useful for batch processing multiple data files at once.
• The --force option can be used to rewrite the data files even if there are no content changes.

Run Without Global Install

You can run the CLI directly or via your package manager without linking globally:

# Directly with Node.js
node bin/cli.js data.md

# pnpm
pnpm exec git-collector data.md

# npm
npm start -- data.md

# Yarn
yarn start -- data.md

Development & Testing

• Run tests:

  pnpm test
  # or
  npm test
  # or
  yarn test
