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 strings from INFILE

-o, --output=OUTFILE

Write output transducer to OUTFILE

String and format options:

-f, --format=FMT

Write result in FMT format

-j, --disjunct-strings

Disjunct all strings instead of transforming each string into a separate transducer

--norm

Divide each weight by sum of all weights (with option -j)

--log

Take negative natural logarithm of each weight

--log10

Take negative 10-based logarithm of each weight

-p, --pairstrings

Input is in pairstring format

-S, --has-spaces

Input has spaces between symbols/symbol pairs

-e, --epsilon=EPS

Interpret string EPS as epsilon.

-m, --multichar-symbols=FILE

Strings that must be tokenized as one symbol.

If OUTFILE or INFILE is missing or -, standard streams will be used. FMT can be { foma, openfst-tropical, openfst-log, sfst, optimized-lookup-weighted, optimized-lookup-unweighted }. If EPS is not defined, the default representation of @0@ is used. Option --norm precedes option --log. The FILE of option -m lists all multichar-symbols, each symbol on its own line. Backslash '\' may be used to escape ':', tab and itself. For any other symbol x '\x' means x literally, i.e. is the same as 'x'. The weight of a string can be given after the string separated by a tabulator. The weight cannot be zero.
