Emtypyie.cli

Build codename: Baking Bread

For downloads and general project details. This wiki covers docs only.

Emtypyie.cli is the package manager and terminal runtime for the EMTYPYIE ecosystem. Running emtypyie with no arguments prints a startup boot animation and drops you into an interactive shell where you can list, install, and manage projects pulled live from a CDN registry.

The project has been maintained continuously since its alpha releases. It started as a Node.js-only tool distributed through npm; from v2.5.0 "Wandering Witches" onward it was rewritten from the ground up in C, and the C (Clang) build has led development ever since — most recently with the v3.0.0 "Baking Bread" major release. See History below for the full timeline.

History

• Alpha
  Node.js-only, npm distribution
  The original CLI was written entirely in Node.js and shipped only through npm.
• v2.5.0 — "Wandering Witches"
  Major release: rewritten in C
  The first major update. The core was rewritten from scratch in C11/C++17 as a dependency-free native binary. The Node.js build was kept alongside it for compatibility.
• Since v2.5.0
  C (Clang) is the primary path
  All new features — Larpino, bakafetch, themes — land in the C build first. The Node.js build is actively maintained alongside it, but typically trails on the newest additions.
• v3.0.0 — "Baking Bread" · Major
  Major release: GUI work begins
  Brought the GUI online alongside the terminal runtime for the first time, continuing the C (Clang)-first direction set since v2.5.0.
• v3.0.1 · Patch
  Patch update
  Follow-up patch to v3.0.0 "Baking Bread" with fixes and stability improvements.
• v3.0.2 · Current
  v3.0.2 is now on
  Latest release. Both the Node.js and C (Clang) builds are up to date on v3.0.2.
• Upcoming — v5.0.0+
  Larpino ships with a bundled default model
  The Larpino engine already runs models today via /get larpino@1b, but shipping a model bundled in by default has been pushed out to v5.0.0 and later — there's plenty of runway before that lands, so no firm timeline yet.

Core features

• Interactive shell with a startup boot animation (skippable via flag or env var)
• Direct one-off commands without entering the shell, e.g. emtypyie /list
• Live CDN-backed project registry — install, inspect, and update anything listed
• Auto-installer for common toolchains, e.g. /get gcc for GCC/G++
• Larpino — a built-in LLAMA inference engine written directly into the C core
• /bf — a neofetch-style system info screen ("bakafetch") with braille/Unicode art
• Five color themes: slate, green, amber, violet, cyan

Install & Launch

The C (Clang) build is the recommended path — it's what gets new features first. The Node.js build is a fully supported alternative too, not just a fallback, but expect it to trail on the newest additions.

Windows (Winget / Chocolatey) — C native build, recommended

# Winget
winget install myrachane.emtypyie-cli

# Chocolatey
choco install emtypyie-cli

npm (all platforms) — Node.js build, maintained

npm install -g emtypyie-cli

This is the original distribution path from the project's alpha days. It's kept up and running today — new features land in the C (Clang) build first, but the Node.js build is not being phased out.

Launching the shell

Once installed, emtypyie is on your PATH. Run it with no arguments to boot the interactive shell:

emtypyie

# skip the boot animation
emtypyie --no-animation
# or
set EMTYPYIE_NO_ANIM=1

Direct commands also work without ever entering the shell, e.g. emtypyie /list or emtypyie /get gcc.

Commands

Architecture

The C CLI (Root4c) is the primary build going forward — a single portable binary written in C11/C++17 (Clang toolchain) with no runtime dependencies. It's what Larpino and bakafetch are built directly into, and where all new development lands first. The Node.js CLI (Root4node) is the original alpha-era codebase, still published to npm, and is officially maintained going forward too — it just receives new features after the C build does.

Larpino inference engine

Larpino, the built-in inference engine, handles:

• GGUF-format LLAMA models — Q4_0, Q4_1, Q5_0, Q5_1, Q8_0, F16, F32
• BPE tokenization with merge rules
• A KV-cached transformer (RoPE, SwiGLU, RMSNorm, grouped-query attention)
• Top-k / temperature sampling

Project listings and metadata for /list, /get, and /info are fetched live from cdn.emtypyie.in/dev — the registry is never bundled with the binary.

Build from source:

cmake -B build
