Lt-trim
lt-trim is the lttoolbox 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.
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.
One minor caveat: 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.
You should not trim a generator unless you have a very simple translator pipeline, since the output of bidix seldom goes unchanged through transfer.
Usage
$ lt-trim analyser_binary bidix_binary trimmed_analyser_binary
E.g. to trim ca-en.automorf.bin using ca-en.autobil.bin:
$ lt-trim ca-en.automorf.bin ca-en.autobil.bin ca-en.automorf-trimmed.bin
