yggdrasil-cli 0.2.2

🤔 What is Yggdrasil?

Yggdrasil CLI is a project flattener and diff tool:
it takes your codebase and transforms it into a single, structured document — or compares snapshots with rich, annotated diffs.

Think of it as tree + cat + diff, but with superpowers:

• 📂 Files → indexed, filtered by extension, glob, or blacklist.
• 📑 Contents → full text for each file, neatly marked.
• 🔗 Anchors → clickable links from index → content (Markdown mode).
• 🎨 Stylish CLI → cyberpunk colors, or plain mode for piping.
• 🛡 Controls → --only, --ignore, --black, --white, --out.
  ↪ --black / --white accept either a file path or launch an interactive paste mode — perfect for dropping in VS Code’s Copy Relative Path output.
• 🧩 Diff Mode → cross-file block detection with [MOVED] annotations.
• 📐 Align Tags → --align-tags keeps metadata comments lined up.

🌟 Why would I want this?

• 🤖 AI Prompts: Feed your repo or a diff as one codex to ChatGPT/Claude.
• 📚 Docs & Reviews: Export a clean snapshot for collaborators.
• 🧑‍💻 Developers: Browse or compare projects with context in your terminal.
• 🗄️ Archival: Serialize project state for reproducibility.

Yggdrasil doesn’t just list files — it builds a codex of your project, and now shows how files evolve.

🛠 How does it work?

Yggdrasil generates two kinds of outputs:

1. Snapshot Mode — index + file contents.
2. Diff Mode — compares two sets of files, showing inline diffs and cross-file [MOVED] metadata.

Snapshot Examples

# Export your repo as Markdown (index + contents)
ygg --show --md --contents --out SHOW.md

# List only file paths (no contents)
ygg --show rs
ygg --show py

Diff Examples

# Compare two versions of a controller
ygg diff controller.py -- controller_old.py

# Compare multiple files against a single snapshot
ygg diff controller.py updates sampling trainer.py -- controller_old.py

# Align tags neatly at a column
ygg diff --align-tags src/ -- old_src/

📄 Manifest files

A manifest is just a plain text file with one path per line. Only the files listed in the manifest will be shown.

Example WHITE.md:

src/pages/codebase.tsx
src/data/codebaseAssets.tsx
src/i18n/codebase.en.json
src/i18n/codebase.es.json
src/types/codebase.ts

Run with:

ygg --show --white WHITE.md --contents

✍️ Interactive Lists (VS Code paste mode)

You don’t even need a manifest file. Run:

ygg --black

or

ygg --white

Then paste your paths — for example, directly from VS Code → Right-click → Copy Relative Path — and finish with:

• Ctrl + D (Linux/macOS)
• Ctrl + Z, then Enter (Windows)

Example:

src/main.rs
src/utils/io.rs
README.md

Each line becomes a filter pattern — instantly usable as a manifest (--white) or ignore list (--black). Perfect for ad-hoc flattening or focused diffs when working on multiple files at once.

🚀 Installation

You’ll need Rust.

cargo install yggdrasil-cli

Then ensure ~/.cargo/bin is in your PATH.

Upgrade after edits:

cargo install --path . --force

🌲 Philosophy

In Norse myth, Yggdrasil is the world-tree connecting all realms. In your terminal, Yggdrasil connects all files — flattening complexity into a single codex, and now diffing branches of your code-tree.

It’s built to be:

• Minimal: no configs, just flags.
• Readable: AI-friendly and human-friendly.
• Extensible: Markdown, CLI, diff formatters, ignore lists, output redirection.

Goal: Make your project’s structure transparent and portable.

🛣 Roadmap

v0.1 → v0.2

• ✅ Index & contents export (--show, --contents)
• ✅ Markdown mode (--md)
• ✅ Ignore & blacklist support (--ignore, --black)
• ✅ Manifest inclusion (--white)
• ✅ Output to file (--out)
• ✅ Cross-file diff engine (ygg diff)
• ✅ [MOVED] metadata overlay
• ✅ --align-tags flag
• ✅ Interactive --black / --white paste mode

Future (v0.3 → v1.0)

• ⏳ Tree vs flat mode toggle
• ⏳ Configurable themes / styles
• ⏳ Unified codex+diff export
