## What it is
Yi is a collection of Haskell libraries for building your own scriptable text editor, with configurable frontends, keymaps, and core editing components. Users assemble a personalized editor from example configurations or write their own configuration in Haskell.

## Use cases
- build a custom text editor in Haskell
- script my editor's behavior in Haskell
- get vim keybindings with a programmable editor
- get emacs-like extensibility in a terminal editor
- create an editor with custom keymaps and modes
- embed an editor core into my own Haskell application

## When to choose
- you want deep, code-level customization of your editor in Haskell
- you want to reuse editor building blocks (frontends, keymaps, modes) in your own project
- you like vim or emacs workflows but want to hack on the editor itself

## When to avoid
- you want an out-of-the-box editor with plugins, not a build-your-own toolkit
- you don't know Haskell or don't want to compile your configuration
- you need a large plugin ecosystem or modern GUI features

## Facets
- artifact type: library
- maturity: maintenance
- function: editor, plugin-system, cli, gui, terminal-ui
- domain: text-editors, developer-tools, programming-languages
- platform: windows, cross-platform, cli
- tags: haskell, scriptable-editor, vim-emulation, emacs-emulation, extensible-editor, linux, macos
