codemirror-clojure

Live demo: https://nextjournal.github.io/codemirror.next-clojure/

Dev Setup

• Install JS deps: yarn install
• Start dev server: shadow-cljs watch app
• Open demo page at http://localhost:8002/

Todo

• "Yank" after kill (https://www.howtogeek.com/293850/how-to-use-macos-built-in-kill-and-yank-as-an-alternative-cut-and-paste/)

Done

• Expand/contract region
• Barf
• Slurp
• Format whitespace (necessary for commands like Slurp to behave nicely)
• Navigate left/right by sexp
• cannot 'indent-all', changes on one line don't affect measurements taken on subsequent lines
• operators are recognized (lists with symbol in 1st position)
• Unwrap current collection
• Kill (remove all children of current node starting on current line)
• GitHub Action to publish demo site to github.io
• indentation
• odd error recovery behaviour - a # token can't be deleted
• deletion
• Copy/paste (only first line copies to clipboard?)
• Ctrl-A => move to beginning of line (first non-whitespace char)
