## What it is
Omelette is a template-based autocompletion helper library for Node.js and Deno CLI applications, generating shell completions for Bash, Zsh, and Fish. It offers a simple event-based and ES6 template literal API for defining completion fragments.

## Use cases
- add bash/zsh/fish autocompletion to a Node CLI
- generate shell completions from a template literal
- add tab-completion to a Deno command-line tool
- dynamically suggest arguments based on filesystem or API data
- set up and clean up shell init files for completions

## When to choose
- you are building a Node or Deno CLI and want easy shell autocompletion
- you want a minimal template-based API rather than a full CLI framework
- you need to support Bash, Zsh, and Fish from one library

## When to avoid
- you need a full CLI argument parser or framework
- your project is not JavaScript/TypeScript based
- you need shells beyond Bash, Zsh, or Fish

## Facets
- artifact type: library
- maturity: maintenance
- function: cli, developer-tools
- domain: developer-tools
- platform: cli, cross-platform
- tags: shell-completion, bash, zsh, fish, autocompletion, coffeescript, command-line, nodejs, deno
