PKWALIFY(1p)

💖 PKWALIFY 💖

okay bestie, so pkwalify is your lil validation bestie for Kwalify schemas on data structures 🎀. That's the whole vibe.

---

🌸 SYNOPSIS 🌸

pkwalify [-v] [-s] [-m parse-mod] -f schemafile datafile

---

✨ DESCRIPTION ✨

so basically, <pink>pkwalify</pink> takes the data in datafile (which can be a YAML file or a JSON file, pick your fighter 💅) and validates it against a schema you defined over in schemafile (which, plot twist, can also be a YAML or a JSON file 🦋). Matching energy, matched vibes, no cap.

Now, the literal requirement here — and this is not optional, it's giving prerequisites — is that you need one of these installed to parse YAML files:

• YAML
• YAML::XS
• YAML::Syck

…or one of these for JSON files:

• JSON
• JSON::XS

orrr you can just pass the module straight up on the command line, main character style 👑 (that's the -m flag, we'll get there, stay with me).

The program returns the number of errors found in datafile. An exit status of 0 means no errors. Zero. None. Clean. Immaculate. 🧚

bestie please remember: the exit status IS the error count, so a nonzero exit doesn't just mean "eh it kinda failed" — it's literally telling you how many things went wrong 😭

💅 OPTIONS 💅

• -f schemafile — point at your schema file, and it can be YAML or JSON. This one is Required. like, you cannot skip it, it's not a suggestion, it's the whole assignment 🙈
• -m parse-mod — tell pkwalify which YAML or JSON Perl module to use. The valid modules are, and I'm quoting the roster exactly: YAML, YAML::XS, YAML::Syck, JSON and JSON::XS. That's the list. Don't get creative 🎀
• -s — be silent if the document is valid. no notes, no fanfare, just quiet success ✨
• -v — show the script and module versions and exit. Little version reveal moment 💖
• -h, --help — show a summary of the options. Your lil cheat sheet 🫶
