✨ NAME ✨

PCRE2 — Perl-compatible regular expressions (revised API). that's the whole name section, she's short and iconic, no notes 💖

---

🌸 SYNOPSIS 🌸

#include <pcre2.h>

int pcre2_set_glob_separator(pcre2_convert_context *cvcontext,
  uint32_t separator_char);

like, that's the whole vibe. two arguments, one int coming back at you 🫶

🦋 DESCRIPTION 🦋

okay so bestie, listen — pcre2_set_glob_separator() is part of an experimental set of pattern conversion functions. yes, experimental, as in, she's still in her testing era, so don't come for her if things get weird 💀

what she does: she sets the component separator character that gets used when converting globs. that's it, that's her whole job, and she does it slayfully ✨

the second argument — that's separator_char — has to be one of these three characters:

• forward slash — /
• backslash — \
• dot — .

that's the whole guest list. nobody else gets in 🙈

the default is lowkey platform-dependent, so keep up:

• backslash when you're running under Windows 🪟
• otherwise, forward slash 🐧🍎

and the result? the function gives you back zero for success — iconic, flawless, no cap — or PCRE2_ERROR_BADDATA if that second argument is invalid. so if you handed her something cursed, she's gonna tell you 🚩

fr fr, if PCRE2_ERROR_BADDATA shows up, it's not her, it's your separator. check your characters before you blame the function 💅

the pattern conversion functions are described in the pcre2convert documentation — go read that one too, it's giving required reading 📚
