Structural Editor

Deprecated: As Calcit shifts toward LLM-generated code workflows, command-line operations and type annotations have become more important. The structural editor approach is no longer recommended. Agent interfaces are preferred over direct user interaction.

As demonstrated in Cirru Project, it's for higher goals of auto-layout code editor. Calcit Editor was incubated in Cirru.

Structural editing makes Calcit a lot different from existing languages, even unique among Lisps.

Calcit Editor uses a calcit.cirru as snapshot file, which contains much informations. And it is compiled into compact.cirru for evaluating. Example of a compact.cirru file is more readable:

{} (:package |app)
  :configs $ {} (:init-fn |app.main/main!) (:reload-fn |app.main/reload!)
    :modules $ []
  :files $ {}
    |app.main $ %{} :FileEntry
      :defs $ {}
        |main! $ quote
          defn main! () (+ 1 2)
        |reload! $ quote
          defn reload! ()
      :ns $ quote
        ns app.main $ :require

Also Hovenia Editor is another experiment rendering S-Expressions into Canvas.
