IFNAMES(1)

💖 IFNAMES 💖

okay bestie, so ifnames is a lil User Command (section 1, she's official) and she's about to become your new fave for snooping on preprocessor conditionals. no cap.

---

✨ NAME ✨

ifnames — extract CPP conditionals from a set of files 🦋

---

🌸 SYNOPSIS 🌸

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

---

💅 DESCRIPTION 💅

so here's the vibe: ifnames scans all of the C source FILES you hand her (or the standard input, if you gave her literally nothing — she's not picky), and then she writes to the standard output a sorted list of every single identifier that shows up in those files inside #if, #elif, #ifdef, or #ifndef directives. she sees all. she tells all. 👑

each identifier gets printed on its own line, followed by a space-separated list of the files where that identifier occurs. it's giving receipts.

• -h, --help — print this help, then exit. your girl is helpful and then she's gone ✨
• -V, --version — print version number, then exit. just the digits, then peace out 💅
