NAME
hfst-lookup - =perform transducer lookup (apply)
SYNOPSIS
hfst-lookup [OPTIONS...] [INFILE]
DESCRIPTION
perform transducer lookup (apply)
Common options:
-h, --help
Print help message
-V, --version
Print version info
-v, --verbose
Print verbosely while processing
-q, --quiet
Only print fatal erros and requested output
-s, --silent
Alias of --quiet
Input/Output options:
-i, --input=INFILE
Read input transducer from INFILE
-o, --output=OUTFILE
Write output to OUTFILE
-p, --pipe-mode[=STREAM] Control input and output streams
Lookup options:
-I, --input-strings=SFILE
Read lookup strings from SFILE
-O, --output-format=OFORMAT
Use OFORMAT printing results sets
-e, --epsilon-format=EPS
Print epsilon as EPS
-F, --input-format=IFORMAT
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
-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 (currently
only works in optimized-lookup mode
-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.
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:
For optimized lookup format, only strings that pass flag
diacritic checks are printed and flag diacritic symbols are not
printed. Support VARIABLE 'print-space' for optimized lookup
format
Known bugs:
'quote-special' quotes spaces that come from 'print-space'
