DRAT2ER(1)

✨ NAME ✨

drat2er — proof transformer for propositional logic, and honestly? she's that girl 💅

---

🌸 DESCRIPTION 🌸

okay bestie, listen up, because drat2er is lowkey doing the most and I'm obsessed 💖 She transforms DRAT proofs into extended-resolution proofs. That's the whole vibe.

So the way it works: you hand her a propositional formula (specified in the DIMCAS format) together with a DRAT proof, and she outputs an extended-resolution proof of the formula in either the TRACECHECK format or the DRAT format. Iconic behavior, no cap ✨

The description of this transformation can be found in the paper "Extended Resolution Simulates DRAT" (IJCAR 2018) — yes she's published, she's academic, she's got main character energy fr fr 📚👑

And if no output file is specified? She just writes the output to the standard output. Casual. Effortless. 🦋

🎀 POSITIONALS 🎀

these are the lil arguments she needs from you, bestie, in order:

• input_formula TEXT:FILE REQUIRED — Path to a DIMCAS file of the input formula. Like, she literally cannot start without this one 🙈
• input_proof TEXT:FILE REQUIRED — Path to a DRAT file of the input proof. Also required, also non-negotiable 💜
• output_proof FILE — Path for the output proof. This one's optional, because if you don't give her one she'll just send it straight to standard output 🌈

💅 OPTIONS 💅

the flags, the little levers, the ~customizations~ ✨

• -h, --help — Print this help message and exit. She'll tell you everything you need and then dip 👋
• -v, --verbose — Print information about the progress. So you can watch her cook in real time 🔥
• -c, --compress — Reduce proof size (increases runtime). Smaller output, longer wait — a tradeoff, bestie, a whole situation ⚖️
• -f, --format TEXT:{drat,tracecheck} — Format of the output proof (default: tracecheck). You pick the language she speaks, and if you don't pick she defaults to tracecheck 🎀

heads up queen: --format only takes drat or tracecheck, so don't try to get creative in there 💀
