#yacc — Public Fediverse posts

Oh, what a wonderful background narrative by the man Aho himself, thank you for the link.

And it's good to see Donald Knuth coming up, with his LALR algorithm and his always-pertinent practice-theory maxim.

Ultimately, I published a third programming language called PeachLang, another simple interpreted language built in Ruby using Racc (the Ruby version of Yacc/Bison).

Fabriquez vos propres compilateurs en Ada avec Aflex et Ayacc
Stéphane vous explique le contenu des dernières versions de ces deux logiciels avec un focus sur la "réentrance".
Bonne lecture

Now here is a nice project to expand your programming horizon. It is a "compiler compiler" in the tradition of flex and yacc:

Here is the (dense) paper about the design and the features:

I think I will probably get my #yacc and #lex skills in shape for the #hikari on #wayland configuration file format. That way I can produce a somewhat readable grammar and hopefully generate better error messages when things are configured the wrong way.
