HFST-SUBSTITUTE(1)

NAME
hfst-substitute - =Relabel transducer arcs

SYNOPSIS
hfst-substitute [OPTIONS...] [INFILE]

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
