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,  transducer2  is
       implicitly surrounded in .* on both sides).

OPTIONS

       -i, --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.

       -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.
