DESCRIPTION

9       Prints out information about an FST.
10
11              Usage: fstinfo [in.fst]
12
13       PROGRAM FLAGS:
14
15       --arc_filter: type = std::string, default = "any"
16
17              Arc  filter:  one  of  "any", "epsilon", "iepsilon", "oepsilon";
18              this only affects the counts of (co)accessible states, connected
19              states, and (strongly) connected components --fst_verify: type =
20              bool, default = true  Verify  FST  sanity  --info_type:  type  =
21              std::string,  default  =  "auto"  Info  format:  one  of "auto",
22              "long", "short", "fast".
23
24       auto: Equivalent to "long" if the  FST  is  an  ExpandedFst,  otherwise
25       "short".  long: Print all properties, computing if unknown; this may be
26       slow for large FSTs.  short: Print  only  type  and  SymbolTable  info.
27       fast:  Print only info that is fast to obtain (by reading only the file
28       header); this is more info than "short", but less than "long".
29
30       --test_properties: type = bool, default = true
31
32              Compute property values (if unknown to FST)

81              weight  (e.g., pair weight, tuple weight and derived classes) to
82              ensure proper I/O of nested composite weights; must have size  0
83              (none) or 2 (open and close parenthesis) --fst_weight_separator:
84              type = std::string, default = ","  Character  separator  between
85              printed composite weights; must be a single character
