LT-TRIM(1) General Commands Manual LT-TRIM(1) 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. 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 + fol- lowed 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. OPTIONS -s, --match-section A section with this name (id@type) in the analyser will only be trimmed against a section with the same id in the bidix. (The de- fault is to trim all sections of the analyser against all sections of the bidix.) Using this option can some times speed up trimming considerably. For example, if you have some complicated regular ex- pressions, try putting them in a <section id="regex" type="standard"> in both .dix files and passing "regex@standard" to --match-section. This argument may be used multiple times to specify multiple sec- tions that must match by name.
