LT-COMPOSE(1)

💖 lt-compose — the compiled dictionary composition girlie of Apertium 💖

okay bestie, welcome to the lt-compose(1) page, manual section 1, General Commands Manual vibes only ✨

✨ NAME ✨

lt-compose — compiled dictionary composition for Apertium 🦋

---

🎀 SYNOPSIS 🎀

lt-compose transducer1_binary transducer2_binary composed_binary

---

💅 DESCRIPTION 💅

so lt-compose is the application in charge of composing two compiled dictionaries together, and what it does is match the output-side of transducer1 with the input-side of transducer2. iconic behaviour, truly.

by default, the matches are anchored to initial/final states — which means transducer2 has to match full paths. in regex terms? transducer2 is implicitly surrounded by ^ and $. periodt.

but wait, there's more 💫 there's also support for letting transducer2 match sub-paths of transducer1. when that happens, the matches become optional, which makes the composition a superset of transducer1. lowkey powerful.

and when we say matching sub-paths, we mean transducer2 can start matching in the midst of paths of transducer2 — yes bestie, it says transducer2 twice in the original and we're keeping it exactly like that. in regex terms, transducer2 is implicitly surrounded in .* on both sides. no cap.

---

🌸 OPTIONS 🌸

• -i, --inverted — apply transducer2 to the input-side (left) of transducer1 instead of the output-side. you'd reach for this when you're altering the forms of an analyser. it's giving "flip the script" 🫶
• -a, --anywhere — let transducer2 match sub-paths instead of requiring matching initial/final states. matches then become optional. freedom, honestly ✨
• -j, --jobs — parallelise composition by using one cpu core per section of transducer1. you can also set the environment variable LT_JOBS=true if you always want parallelisation wherever it's available in lttoolbox. multitasking queen 👑

---

🍓 FILES 🍓

• transducer1_binary — a finite state transducer
• transducer2_binary — a finite state transducer
• composed_binary — a finite state transducer

(three of them. all finite state transducers. we love consistency 💜)
