LT-COMPOSE(1)		    General Commands Manual		 LT-COMPOSE(1)

NAME
       lt-compose -- compiled dictionary composition for Apertium

SYNOPSIS
       lt-compose transducer1_binary transducer2_binary	composed_binary

DESCRIPTION
       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,	trans-
       ducer2 is implicitly surrounded in .* on	both sides).

OPTIONS
       -i, --inverted
	       Apply transducer2 to the	input-side (left) of  transducer1  in-
	       stead  of  the output-side. You would do	this when altering the
	       forms of	an analyser.

       -a, --anywhere
	       Allow transducer2  to  match  sub-paths	instead	 of  requiring
	       matching	initial/final states. Matches then become optional.

       -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 where available
	       in lttoolbox.
