perform transducer lookup (apply) NOTE: hfst-lookup does lookup from left to right as opposed to xfst and
foma
lookup which is carried out from right to left. In order to do lookup in a similar way as xfst and
foma, use 'hfst-flookup' instead.
Commonoptions:-h, --help
Print help message
-V, --version
Print version info
-v, --verbose
Print verbosely while processing

Alias of --quietInput/Outputoptions:-i, --input=INFILE
Read input transducer from INFILE
-o, --output=OUTFILE
Write output to OUTFILE

Use IFORMAT parsing input
-x, --statistics
Print statistics
-X, --xfst=VARIABLE
Toggle xfst VARIABLE
-c, --cycles=INT
How many times to follow input epsilon cycles (only for non-lookup-optimized transducers)
-n, --max-number=INT
Maximum number of results printed for each input (only for lookup-optimized transducers)
-b, --beam=B
Output only analyses whose weight is within B from the best analysis
-t, --time-cutoff=S
Limit search after having used S seconds per input (only for lookup-optimized transducers)
-C, --cascade=CASCADE
How multiple transducers in input are handled
-P, --progress
Show neat progress bar if possible
If OUTFILE or INFILE is missing or -, standard streams will be used. Format of result depends on format
of INFILE OFORMAT is one of {xerox,cg,apertium}, xerox being default IFORMAT is one of
{text,spaced,apertium}, default being text, unless OFORMAT is apertium VARIABLEs relevant to lookup are
{print-pairs,print-space, quote-special,show-flags,obey-flags} Input epsilon cycles are followed by
default INT=5 times. Epsilon is printed by default as an empty string. B must be a non-negative float.
S must be a non-negative float. The default, 0.0, indicates no cutoff. If the input contains several
transducers, a set containing results from all transducers is printed for each input string.
CASCADE must be one of { union, priority-union, composition }. If not specified, defaults to {union}.
STREAM can be { input, output, both }. If not given, defaults to {both}. If input file is not specified
with -I, input is read interactively line by line from the user. If you redirect input from a file, use
--pipe-mode=input. --pipe-mode=output is ignored on non-windows platforms.
Todo:
Support --xfst=obey-flags for optimized lookup format. Support --cycles for optimized lookup
format.
Knownbugs:
'quote-special' quotes spaces that come from 'print-space'
