Pretty Print Tree Data Structures in Common Lisp

CL-PrettyPrintTrees.ipynb

That's nice! Well done!

Btw.:

• you can get rid of the (APPLY #'NCONC ...) if you APPEND in the LOOPs, instead of COLLECT.

• it's usually better to put a WITH clause before all the FOR clauses

• one can also write FOR (head . tail) ON lower-children

Hi Vsevolod, Thanks for the link. Very nice post!. I also like your Lisp blog. I’ve put a number of your posts on my reading list. In your post you state: _“I, in fact, was always interested in creative ways of text-based visualization.”_ Then, maybe you find this interesting too: svgbob<https://ivanceras.github.io/md/Svgbob.md>. This tool transforms ASCII art into svg images. At first glance a hilarious idea, but I found that this is sometimes quite handy. The GitHub project is here: https://github.com/ivanceras/svgbob Peter

Hi lispm,

Your suggestions are very much appreciated! I'll look into them as soon as I can.

• you can get rid of the (APPLY #'NCONC ...) if you APPEND in the LOOPs, instead of COLLECT.

Thanks for the pointer to svgbob. I'm collecting such references. A great list of different ASCII and similar visualization tools is crowdsourced here: https://twitter.com/SusanPotter/status/1189165775275331584
