manual page for fstinfo 1.8.3

Description

Prints out information about an FST.

Usage: fstinfo [in.fst]

PROGRAM FLAGS:

--arc_filter: type = std::string, default = "any"

Arc filter: one of "any", "epsilon", "iepsilon", "oepsilon"; this only affects the counts of (co)accessible states, connected states, and (strongly) connected components --fst_verify: type = bool, default = true Verify FST sanity --info_type: type = std::string, default = "auto" Info format: one of "auto", "long", "short", "fast".

auto: Equivalent to "long" if the FST is an ExpandedFst, otherwise "short". long: Print all properties, computing if unknown; this may be slow for large FSTs. short: Print only type and SymbolTable info. fast: Print only info that is fast to obtain (by reading only the file header); this is more info than "short", but less than "long".

--test_properties: type = bool, default = true

Compute property values (if unknown to FST)

LIBRARY FLAGS:

Flags from: flags.cc

--help: type = bool, default = false

show usage information --helpshort: type = bool, default = false show brief usage information --tmpdir: type = std::string, default = "/tmp" temporary directory --v: type = int32_t, default = 0 verbosity level

Flags from: fst.cc

--fst_align: type = bool, default = false

Write FST data aligned where appropriate --fst_default_cache_gc: type = bool, default = true Enable garbage collection of cache --fst_default_cache_gc_limit: type = int64_t, default = 1048576 Cache byte size that triggers garbage collection --fst_read_mode: type = std::string, default = "read" Default file reading mode for mappable files --fst_verify_properties: type = bool, default = false Verify FST properties queried by TestProperties --save_relabel_ipairs: type = std::string, default = "" Save input relabel pairs to file --save_relabel_opairs: type = std::string, default = "" Save output relabel pairs to file

Flags from: symbol-table.cc

--fst_compat_symbols: type = bool, default = true

Require symbol tables to match when appropriate --fst_field_separator: type = std::string, default = "         " Set of characters used as a separator between printed fields

Flags from: util.cc

--fst_error_fatal: type = bool, default = true

FST errors are fatal; o.w. return objects flagged as bad: e.g., FSTs: kError property set, FST weights: not a Member()

Flags from: weight.cc

--fst_weight_parentheses: type = std::string, default = ""

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) --fst_weight_separator: type = std::string, default = "," Character separator between printed composite weights; must be a single character
