pdtshortestpath — find the shortest path in a PDT


pdtshortestpath [Options] in.pdt [out.fst]


Finds the shortest path in a (bounded-stack) PDT.


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


Write FST data aligned where appropriate.  Default: false.


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


Enable garbage collection of cache.  Default: true.


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


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.


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


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


Verify fst properties queried by TestProperties.  Default: false.


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.


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


Show usage information.  Default: false.


Show brief usage information.  Default: false.


Keep PDT parentheses in the result.  Default: false.


Garbage collect the shortest path data.  Default: true.


Set the PDT parenthesis label pairs.


Set the queue type, one of fifo, lifo, and state.  Default: fifo.


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


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


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


Set the verbosity level.  Default: 0.
