#pikchr — Public Fediverse posts

@jaredj I've been using #pikchr on my blog, and it's really nice to generate Pikchr output from a script.

DSP and CRC block diagrams: https://remcycles.net/blog/goertzel.html, https://remcycles.net/blog/crc_diagrams.html

Some animations (pikchrs->svgs->pngs->animated gifs): https://remcycles.net/blog/corr_viz.html

@jaredj
There was #PlantUML, then someone else created #Mermaid (not sure it fit #Emacs, though), now #Pikchr...

@ross I've noticed this handy feature while generating SVGs using Pikchr, Emacs, and org-mode. Some fun examples on my blog:

#emacs #pikchr #orgmode #svg

I've just written my first non toy #pikchr diagram and I can see it potentially replacing #ditaa and #artistmode for some of my diagram needs. https://pikchr.org/home/doc/trunk/homepage.md

@22 The #SQLite syntax diagrams are produced with the #pikchr tool, by the same author as #SQLite and #fossil D Richard Hipp.
"Pikchr (pronounced "picture") is a PIC-like markup language for diagrams in technical documentation. Pikchr is designed to be embedded in fenced code blocks of Markdown or similar mechanisms of other documentation markup languages."

@alexlehm I was reminded of #pikchr when @jpmens mentioned #PIC https://mastodon.social/@jpmens/111065438408351693 because pikchr's syntax is more or less the same https://pikchr.org/home/doc/trunk/doc/differences.md

Inspired by the #TikZ examples in the Microsoft report on GPT-4 https://arxiv.org/pdf/2303.12712.pdf, I tried to have #ChatGPT draw a stick figure in #pikchr. It doesn’t really work, except as a motivation to read the manual… But it’s impressive how it takes your corrections into account. #GPT4 (tried in https://lex.page) seems to produce more elaborate code (with comments!), but it mostly doesn’t work either—and without being able to chat with it, it’s not useful for this purpose.
