lt-composecompiled dictionary composition for Apertium


lt-compose transducer1_binary transducer2_binary composed_binary


lt-compose is the application responsible for composing two compiled dictionaries, matching the output-side of transducer1 with the input-side of transducer2. By default, matches are anchored to initial/final states, so the transducer2 has to match full paths (in regex terms, transducer2 is implicitly surrounded by ^ and $). But there is also support for letting transducer2 match sub-paths of transducer1 (in which matches become optional, making the composition a superset of transducer1). Matching sub-paths means that transducer2 can start matching in the midst of paths of transducer2 (in regex terms, transducer2 is implicitly surrounded in .* on both sides).


, --inverted
Apply transducer2 to the input-side (left) of transducer1 instead of the output-side. You would do this when altering the forms of an analyser.
, --anywhere
Allow transducer2 to match sub-paths instead of requiring matching initial/final states. Matches then become optional.
, --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 where available in lttoolbox.
