SYNOPSIS

DESCRIPTION

Compiles a set of strings as FSTs and stores them in a finite-state archive.

OPTIONS

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

--allow_negative_labels[=BOOLEAN]

Allow negative labels (not recommended; may cause conflicts). Default: false.

--arc_type=TYPE

Set the output arc type. Default: standard.

--entry_type=TYPE

Set the entry type, either file (one FST per file) or line (one FST per line). Default: line.

--far_type=TYPE

Set the FAR file format, one of default, fst, stlist, or sttable. Default: default.

--file_list_input[=BOOLEAN]

Each input file contains a list of files to be processed. Default: false.

--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_type=TYPE

Set the output FST type. Default: vector.

--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.

--generate_keys=N

Generate N digit numeric keys. Default: use file basenames.

--help[=BOOLEAN]

Show usage information. Default: false.

--helpshort[=BOOLEAN]

Show brief usage information. Default: false.

--initial-symbols[=BOOLEAN]

If --keep-symbols is true, store the symbol table for only the first FST in the archive. Default: true.

--keep-symbols[=BOOLEAN]

Store the symbol table in the FAR file. Default: false.

--key_prefix=STRING

Set the prefix to prepend to keys. Default: no prefix.

--key_suffix=STRING

Set the suffix to append to keys. Default: no suffix.

--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.

--symbols=FILENAME

Read the label symbol table from a file. Default: do not read a table.

--tmpdir=PATHNAME

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

--token_type=TYPE

Set the token type, one of symbol, byte, or utf8. Default: symbol.

--unknown-symbol=STRING

String to substitute for an unknown symbol.

--v[=N]

Set the verbosity level. Default: 0.
