Configurable Text Editor In Pure Elm

This is just a fun project. It is a text editor that supports highlighting through provided parser and basic editor actions. The editor is optimized to handle large texts (hundreds of thousands of characters). I took inspiration for some performance optimizations from the great Ace editor.

The editor is meant as a package, exporting init, update and view functions and some related types from the Main.elm module. However, there is the Playground.elm file with an example usage linked in the index.html to try it out.

Getting Started

To try the example:

1. Run npm i to install npm dependencies (most notably elm itself)
2. Run npm run make to compile the example (outputs resulting js file into generated directory)
3. Open the index.html file and try out the editor

Next Steps

• Expand configurability of the editor. Especially keyboard handling.
• Add several prepared configuration to have options for a quick start.
• Add support for popovers on cursor or line number.
• Add support for multiple cursors.
