💅 HAILO(1) — the Hailo Markov bot, command-line edition

okay so bestie, this is hailo, the command-line interface to the Hailo Markov bot. Yes, the manual name is Hailo, yes it's a Perl thing, no you don't have to be scared. sit down, drink some water, we're doing this 🫶

    Note: All input/output and files are assumed to be UTF-8 encoded.
⚠️ heads up queen: all input/output and files are assumed to be UTF-8 encoded. like, that's the whole vibe. don't come at it with weird encodings, it will simply not slay.

🦋 SYNOPSIS 🦋

train in-memory using bot-training's megahal.trn and reply

bot-training -f megahal | hailo --brain :memory: --train - --random-reply
# ==> Time flies like a banana.

literally the whole thing in one pipe, it's giving efficiency 👑

create an on-disk brain for later use

bot-training -f megahal > megahal.trn
hailo --brain hailo.sqlite --train megahal.trn
hailo --brain hailo.sqlite --reply 'Reply to this, silly robot!'
# ==> No way! I don't want to think.

yes bestie, hailo.sqlite is the brain file here — write it down, you'll use it again 🧠

interact with the brain using readline

hailo --brain hailo.sqlite
Welcome to the Hailo interactive shell!
Enter ".help" to show the built-in commands.
Input that's not a command will be passed to Hailo to learn, and it'll
reply back.
Hailo> Hello there
# ==> Wife asked "what have you got there?" replied he, "just my cup of fur".

the interactive shell is lowkey the main character here. type .help and it shows you the built-in commands, and anything that isn't a command gets passed to Hailo — it learns from it AND replies back. so you're basically feeding it and hearing it talk at the same time, which is iconic honestly 💀

🌸 DESCRIPTION 🌸

See the documentation for Hailo for more information.

(that's it. that's the description. they really said "go read the other docs" and honestly? respect. if you want the deep lore, the Hailo documentation is where it lives 📖✨)

🎀 OPTIONS 🎀

okay here's the full menu, no skips, no cuts, every single one:

  • -v, --version — print the version and dip. that's the whole job 🫡
  • -u, --ui — use UI CLASS. pick your interface, choose your fighter.
  • -t, --train — learn from all the lines in FILE; use - for STDIN. feed the bot, it's hungry.
  • -s, --stats — print statistics about the brain. brain tea ☕
  • -r, --reply — reply to STRING. give it a prompt, get a reply.
  • -p, --progress — display progress during the import. so you're not just staring at a cursor like an idiot 🙈
  • -o, --order — Markov order; "How deep the rabbit hole goes". yes that's the official description and yes it ate 🐇
  • -l, --learn — learn from STRING. one little snack for the brain.
  • -h, --help — "You're soaking it in". iconic line, no notes. shows you the help.
  • -f, --train-fast — train with aggressive caching. 🚨 memory-hungry! the manpage put an exclamation mark on it so I'm putting one too — it will eat your RAM, bestie.
  • -b, --brain — load/save brain to/from FILE. this is your brain file, guard it with your life 💖
  • -a, --autosave — save the brain on exit. on by default, so it's already doing it for you, you're welcome.
  • -T, --tokenizer — use tokenizer CLASS.
  • -S, --storage — use storage CLASS.
  • -R, --random-reply — like --reply but takes no STRING; babble at random ✨ chaos mode activated.
  • -L, --learn-reply — learn from STRING and reply to it. two things at once, multitasking queen 👑
  • -E, --engine — use engine CLASS.
  • --ui-args — arguments for the UI class.
  • --tokenizer-args — arguments for the Tokenizer class.
  • --storage-args — arguments for the Storage class.
  • --examples — print examples along with the help message. yes please, show me the receipts 🔥
  • --engine-args — arguments for the Engine class.
  • --brain-resource — alias for `brain' for backwards compatibility. old code still gets love 🫶
💡 fr fr note, repeated because it matters: all input/output and files are assumed to be UTF-8 encoded.
