Convert a Lisp expression to a tree diagram

Convert a Lisp expression to a tree diagram

[Juan Manuel Macías]

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

Invoking search across my notes and archives (all stored in Org, of
course) yielded the following:

Hope it helps.

Thanks a lot, Ihor! There is some very juicy information there.

Awesome notes. Hats off to such a detailed capture (reminds me to give
my poor org-capture templates some more love one day :-))

Best regards,

Thank you! It is very complete, and I have seen that it also integrates
with qutebrowser. I'll try it as soon as I have time.

This one draws graph of cons cells (lists):

I never tried with random s-expressions, but I guess you could pass them in as lists?

Hi, Arthur,

Thank you for the pointer to draw-cons-tree. I didn't know this package,
I'll take a look.

Best regards,
