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
