NAME

       lt-trim — compiled dictionary trimmer for Apertium

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(1)  -b
       bidix_binary’ are kept.

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

       Both  compound  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(1) -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(1) 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.
