NAME¶

pdtreplace - convert an RTN into a PDT

SYNOPSIS¶

pdtreplace [OPTIONS] root.fst rootlabel [rule.fst label...] [out.fst]

DESCRIPTION¶

Convert an RTN represented by FSTs and non-terminal labels into a PDT.

OPTIONS¶

Boolean options accept either true or false as a value, or the implicit value true if neither value is specified.

--fst_align[=BOOLEAN]

Write FST data aligned where appropriate. Default: false.

--fst_compat_symbols[=BOOLEAN]

Require symbol tables to match when appropriate. Default: true.

--fst_default_cache_gc[=BOOLEAN]

Enable garbage collection of cache. Default: true.

--fst_default_cache_gc_limit=N

Set the cache byte size that triggers garbage collection. Default: 1048576.

--fst_error_fatal[=BOOLEAN]

If true, FST errors are fatal. Otherwise, returned objects are flagged as bad. For example, FSTs are returned with the kError property set to true, and FST weights set so that Member() returns false. Default: true.

--fst_field_separator=STRING

Set the characters used as a separator between printed fields. Default: " ".

--fst_read_mode=STRING

Set the default file reading mode for mappable files, either "read" or "map". Default: "read".

--fst_verify_properties[=BOOLEAN]

Verify fst properties queried by TestProperties. Default: false.

--fst_weight_parentheses=STRING

Set the characters enclosing the first weight of a printed composite weight (e.g., pair weight, tuple weight, and derived classes) to ensure proper I/O of nested composite weights. Must have size 0 (none) or 2 (open and close parenthesis). Default: no parentheses.

--fst_weight_separator=CHARACTER

Set the character separator between printed composite weights. Default: comma.

--help[=BOOLEAN]

Show usage information. Default: false.

--helpshort[=BOOLEAN]

Show brief usage information. Default: false.

--left_paren_prefix=STRING

Prefix to attach to SymbolTable labels for inserted left parentheses. Default: "(_".

--pdt_parser_type=STRING

Construction method, either "left" or "left_sr". Default: "left".

--pdt_parentheses=STRING

Set the PDT parenthesis label pairs.

--right_paren_prefix=STRING

Prefix to attach to SymbolTable labels for inserted right parentheses. Default: ")_".

--save_relabel_ipairs=FILENAME

Save input relabel pairs to file. Default: do not save.

--save_relabel_opairs=FILENAME

Save output relabel pairs to file. Default: do not save.

--start_paren_labels=INTEGER

Index to use for the first inserted parentheses; if not specified, the next available label beyond the highest output label is used.

--tmpdir=PATHNAME

Set the temporary directory to use. Default: /tmp.

--v[=N]

Set the verbosity level. Default: 0.
