IFNAMES(1)

💅 ifnames(1) — User Commands 💅

🌸 NAME 🌸

ifnames — Extract CPP conditionals from a set of files. periodt. 💅

✨ SYNOPSIS ✨

ifnames [OPTION]... [FILE]...

💖 DESCRIPTION 💖

okay so ifnames scans all of the C source FILES — or the standard input, if none are given — and writes to the standard output a sorted list of all the identifiers that appear in those files in #if, #elif, #ifdef, or #ifndef directives. it's giving “who’s showing up in the conditionals?” energy 🕵️‍♀️✨

then it prints each identifier on a line, followed by a space-separated list of the files in which that identifier occurs. no cap, that’s the whole vibe.

the flags are basically two little icons:

• -h, --help — print this help, then exit. bye bestie 👋
• -V, --version — print version number, then exit. slay 💅
