A library to determine the subregular classification of a given language. It is recommended to use Maven to build this code from source, as a pom.xml file specifying all of the dependencies is included.
This library is currently setup to determine whether a given FST is aperiodic (i.e. star-free). To test your FST, first specify it in one or more files (depending on whether you use state symbols, etc.) written in the AT&T FSM format (see example *.fst.txt files to see what this format looks like). The files you want to test should be placed within the src/main/resources directory. Once you have done this, execute the following shell commands:
$ mvn compile package$ java -jar target/sbfst-1.0-SNAPSHOT-shaded.jar [file containing AT&T text formatted fst]
