WIP lisp structural editor

ast.lisp is an almost complete parser for common lisp. tui.lisp is a terminal UI using uncursed.

Currently mainly testing on sbcl due to non-standard macroexpansions. The point of structural editing is proven ergonomics (e.g. paredit, vim) adapted to a fully tree-structured context and to have incremental accurate type analysis and tracking of image state.

• An interesting technique is used to lexically analyse macro calls, I'm working on a writeup for ELS next year.
• Currently implemented is a generalization of zipper selection as described in pantograph.

Ask me on the lisp discord if you have any questions :D

In a terminal load

(ql:quickload :slynk) ; for sly users, this is slynk
(slynk:create-server :dont-close t :port 4005)
(loop (sleep 1))

In emacs, sly-connect to 4005 and

(ql:quickload :weave)
(weave-tui:main)

• Space inserts or moves to the next hole

• Enter selects a completion/expands the symbol at point into a call

• C-n/p/b/f move by atom and goal column

• M-n/p move by parent stack

• Shift+left/right starts a selection

• Shift+up/down adjusts a zipper selection

• C-x/c/v cut, copy and paste
