NAME

       lt-trim - This application is part of the lexical processing modules and tools ( lttoolbox )

       This tool is part of the apertium machine translation architecture: http://www.apertium.org.

SYNOPSIS

       lt-trim analyser_binary bidix_binary trimmed_analyser_binary

DESCRIPTION

       lt-trim  is the application responsible for trimming compiled dictionaries. The analyses (right-side when
       compiling lr) of analyser_binary are trimmed to the input side of bidix_binary (left-side when  compiling
       lr,  right-side  when  compiling  rl),  such  that  only  analyses  which  would pass through `lt-proc -b
       bidix_binary' are kept.

       Warning: this program is experimental! It has been tested, but not deployed extensively yet.

       Both compund tags (`<compound-only-L>', `<compound-R>') and join elements (`<j/>'  in  XML,  `+'  in  the
       stream)  and  the  group  element  (`<g/>'  in  XML, `#' in the stream) should be handled correctly, even
       combinations of + followed by # in monodix are handled.

       Some minor caveats: If you have the capitalised lemma "Foo" in the monodix, but "foo" in  the  bidix,  an
       analysis  "^Foo<tag>$"  would  pass  through  bidix  when  doing lt-proc -b, but will not make it through
       trimming. Make sure your lemmas have the same capitalisation in the  different  dictionaries.  Also,  you
       should  not  have  literal  `+' or `#' in your lemmas. Since lt-comp doesn't escape these, lt-trim cannot
       know that they are different from `<j/>' or `<g/>', and you may get @-marked output  this  way.  You  can
       analyse  `+' or `#' by having the literal symbol in the `<l>' part and some other string (e.g. "plus") in
       the `<r>'.

       You should not trim a generator unless you have a very simple translator pipeline, since  the  output  of
       bidix seldom goes unchanged through transfer.
