Just before the last week of my internship, my Lean parser in Lean can now parse github.com/leanprover/lea (which is already pretty comprehensive regarding grammar coverage)
Now we just have to make it fast, starting with specialization and a native back end...

Still have to create the final presentation; I'm considering ditching LaTeX for that even if there will be some formulas in there. What are people using nowadays for nice and simple presentations? reveal.js?

I use Racket's slideshow package. Can call to LaTeX if you really need a formula, supports animations, allows embedded GUI widgets for nice demos.

Can it do syntax highlighting of custom programming langs? That would be super handy.

If they're Lispy then the included lib does a good job. If not, then you'd have to build a little lexer.

At least you get to use a reasonable language to build extensions...

That'll do it. If you don't want to use the #lang for anything but slides, then this might be overkill relative to just writing some regexps to dump a highlighted picture out of a string.

Might be good procrastination material for my next talk! At least I'd learn more about Racket's language implementation stuff! Always wanted to have an excuse to learn. 🤔

You can also go completely over the top like I did for ICFP 16 and have your compiler talk to your slides over a socket for a mini ide in the slides...

Hah, I liked that one! Where you showed off Pie? Looked super nice.
Pie runs in-process, no need for the socket
