✨ NAME ✨

okay so bestie, say hi to asn1Parser — it's the ASN.1 syntax tree generator for libtasn1. it literally turns your ASN.1 definitions into a little C array and hands it to libtasn1. it's giving ✨compiler energy✨ but make it cute.

🌸 SYNOPSIS 🌸

asn1Parser [OPTION] FILE

like. you give it a FILE, you give it options, it does its thing. that's the whole vibe. 🦋

💖 DESCRIPTION 💖

so what actually happens: it reads FILE, which is full of ASN.1 definitions, and generates a C array that you then use with libtasn1 functions. no cap, that's the whole job and it does it flawlessly. 💅

Mandatory arguments to long options are mandatory for short options too. (yes bestie, that's a real sentence, and it's important — if a long option needs a value, its short version needs that same value. iykyk.)

  • -c, --check — just checks the syntax. that's it. it looks at your file, goes "hmm okay 👀", and reports whether the syntax is valid. no output file, no drama, just the vibe check. 🔥
  • -o, --output=FILE — tells it where to put the output. give it a FILE and that's where the generated stuff lands. 🎀
  • -n, --name=NAME — sets the array name. so like, the C array it makes? you get to name it. NAME is the name. iconic behavior honestly. 👑
  • -h, --help — displays the help and exits. your classic "wait how does this work again" button. 🙈
  • -v, --version — spits out version information and exits. for when you need to know exactly which era of this software you're living in. ⭐
