This one draws graph of cons cells (lists): https://github.com/amno1/draw-cons-tree I never tried with random s-expressions, but I guess you could pass them in as lists? -------- Originalmeddelande -------- Från: Juan Manuel Macías Datum: 2022-06-30 16:20 (GMT+01:00) Till: orgmode Ämne: Convert a Lisp expression to a tree diagram Hi all, Sorry for the slight offtopic. I'd like to be able to graphically convert (from a src block) a Lisp expression to a tree diagram, similar to trees used in (human) syntax and grammar, especially generative grammar (this is a web app for generating such trees: http://www.ironcreek.net/syntaxtree/). I think I can try some LaTeX hack using the 'forest' package (here's a related thread with pros and cons: https://tex.stackexchange.com/questions/140812/drawing-a-lisp-expression-as-a-tree), but I was wondering if anyone knows of any more emacs/elisp/org friendly packages/solutions. Some time ago I saw an Emacs package that could convert a Elisp expression into an ascii text tree diagram, but I can't remember its name and I can't find it anywhere... Best regards, Juan Manuel
