NGRAMINFO(1)

🌸 NAME 🌸

ngraminfo — the manual page for ngraminfo 1.3.17, bestie 💖

---

✨ DESCRIPTION ✨

Okay so, no cap, what this icon does is print out various information about an LM. That's it. That's the whole gig. She's giving ✨informant✨ and honestly? We love that for her. 💅

Here's how you run her:

Usage: ngraminfo [--options] [in.fst [out.txt]]

So you give her an in.fst, maybe an out.txt, sprinkle in some --options, and she spills the tea about your LM. Obsessed. 🫶

---

🎀 PROGRAM FLAGS: 🎀

• --check_consistency — type = bool, default = true. She checks your model's consistency. Like a vibe check, but for your LM, and she will absolutely tell you if something's off. 💀
• --norm_eps — type = double, default = 0.001. The epsilon used for the normalization check. Tiny number, big responsibility, main character energy fr fr. ✨

---

📚 LIBRARY FLAGS: 📚

🌈 Flags from: flags.cc

• --help — type = bool, default = false. Show usage information. The classic "help meee" button, and yes she will help you. 🥺
• --helpshort — type = bool, default = false. Show brief usage information. Same energy, but short and sweet, like a text you send when you're lowkey in a rush. 💌
• --tmpdir — type = std::string, default = "/tmp". The temporary directory. Her lil scratch space, her little corner of the filesystem. 🏠
• --v — type = int32_t, default = 0. Verbosity level. Crank it up if you want her to be chatty. She will yap. 🗣️

🦋 Flags from: fst.cc

• --fst_align — type = bool, default = false. Write FST data aligned where appropriate. Fancy posture for your data, slay. 💅
• --fst_default_cache_gc — type = bool, default = true. Enable garbage collection of cache. Cleaning up after herself, we stan a tidy queen. 🧹
• --fst_default_cache_gc_limit — type = int64_t, default = 1048576. The cache byte size that triggers garbage collection. Hit the limit, and the cleanup starts. Periodt. 🔥
• --fst_read_mode — type = std::string, default = "read". Default file reading mode for mappable files. She's in her reading era. 📖
• --fst_verify_properties — type = bool, default = false. Verify FST properties queried by TestProperties. She double-checks. Trust issues? No, just thorough. 👑
• --save_relabel_ipairs — type = std::string, default = "". Save input relabel pairs to file. Empty string means she's not doing it, so speak up if you want it. 🍓
• --save_relabel_opairs — type = std::string, default = "". Save output relabel pairs to file. Same deal, but the output side. The mirror, the twin, the other half. 🪞

⭐ Flags from: symbol-table.cc

• --fst_compat_symbols — type = bool, default = true. Require symbol tables to match when appropriate. Compatibility check, because she's not about that mismatched-symbol chaos. 💜
• --fst_field_separator — type = std::string, default = " ". Set of characters used as a separator between printed fields. Yes, that default is literally a bunch of spaces. She said "spaces only, no notes." 🙈

💖 Flags from: util.cc

• --fst_error_fatal — type = bool, default = true. FST errors are fatal; o.w. return objects flagged as bad: e.g., FSTs: kError property set, FST weights: not a Member(). So like, by default an error is a whole dramatic exit. Set it otherwise and she'll hand you back objects marked as bad instead. Choose your adventure, bestie. 😭

🌸 Flags from: weight.cc

• --fst_weight_parentheses — type = std::string, default = "". Characters enclosing the first weight of a printed composite weight (e.g., pair weight, tuple weight and derived classes) to ensure proper I/O of nested composite weights; must have size 0 (none) or 2 (open and close parenthesis). So it's either nothing or a lil matching set — no in-between, she doesn't do half-measures. 🧚
• --fst_weight_separator — type = std::string, default = ",". Character separator between printed composite weights; must be a single character. One character only, she is very strict about this and honestly? Respect. ✨

---

🌟 Friendly lil heads-up: a bunch of these flags have rules attached (--fst_weight_parentheses has to be size 0 or 2, --fst_weight_separator has to be exactly one character). She's not being difficult, she's just built different. Follow the rules and she'll treat you right. 💅

And that's the whole page, bestie — this was ngraminfo 1.3.17, dated February 2022, and she ate. 💖✨🎀 Stay consistent, keep your epsilons tiny, and go read your FSTs. Byeee! 🦋🌈💜
