SYNOPSIS

DESCRIPTION

Relabel transducer arcs

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 transducer to OUTFILE

Relabeling options:

-f, --from-label=FLABEL
replace FLABEL
-t, --to-label=TLABEL
replace with TLABEL
-T, --to-transducer=TFILE
replace with transducer read from TFILE
-F, --from-file=LABELFILE
read replacements from LABELFILE
-R, --in-order
keep the order of the replacements (with -F)

Input options:

-C, --do-not-convert
require that transducers in TFILE and INFILE have the same type

Transient optimisation schemes:

-9, --compose
compose substitutions when possible

If OUTFILE or INFILE is missing or -, standard streams will be used. Format of result depends on format of INFILE LABEL must be a symbol name in single arc in transducer, or colon separated pair defining an arc. If TFILE is specified, FLABEL must be a pair. LABELFILE is a 2 column tsv file where col 1 is FLABEL and col 2 gives TLABEL specifications.

EXAMPLES

hfst-substitute -i tr.hfst -o tr_relabeled.hfst -f 'a' -t 'A'
relabel all symbols 'a' with 'A'
hfst-substitute -i tr.hfst -o tr_relabeled.hfst -f 'a:b' -t 'A:B'
relabel all arcs 'a:b' with 'A:B'
hfst-substitute -i tr.hfst -o tr_relabeled.hfst -f 'a:b' -T repl.hfst
replace all arcs 'a:b' with transducer repl.hfst
