✨ NAME ✨

okay bestie, say hi to yyextract 💖 — she extracts grammar rules from a yacc grammar. that's it, that's the whole job, and she does it flawlessly 🦋

🌸 SYNOPSIS 🌸

yyextract [-behyV] [-o file] [-t title] [-w cols] [file ...]

like. look at her. the flags. the files. the whole vibe. 👑

💜 DESCRIPTION 💜

so basically? the yyextract utility extracts the grammar rules from a yacc grammar. that's the tea 🍓 it reads your grammar and pulls the rules out so you don't have to go dig for them yourself. no cap.

🎀 OPTIONS 🎀

here's the full menu, bestie, and yes you're gonna want to read all of them 💅

  • -b — pick the Backus-Naur Form (BNF) for the output ✨
  • -e — pick the Extended Backus-Naur Form (EBNF) for the output 🦋
  • -h — output in HTML format 🌈
  • -o file — set the output destination to file 📁
  • -t title — specify the page title for the generated HTML page 👑
  • -w cols — set the width limit of the output (heads up, this sets only the width of the %token header 🙈)
  • -y — pick the yacc format for the output. this one is the default format, so if you say nothing, this is what you get 💖
  • -V — print version information on standard output then exit. she says hi and dips 😭

🫶 NOTES 🫶

ok so real talk: the Extended Backus-Naur Form (EBNF) is like the Backus-Naur Form (BNF) but with the empty rules translated with the zero-or-one operator (within the brackets '[' and ']'). so it's giving BNF's cooler cousin, fr fr 💀✨
