A static cross-platform library for parsing, generating, manipulating, and matching strings against JSGF grammars. This is a C++ port of the Java JSGFKit with a few additional features.
Run the below commands to compile with CMake:
cmake CMakeLists.txt -Bbuild
cd build
make
To include and link against the JSGF Kit++ static library, use pkg-config:
pkg-config --libs --cflags jsgfkit
A hosted version of the Doxygen generated docs can be found here: http://personal.psu.edu/~txs5620/jsgfkitxx/
Doxygen documentation comments are in the code, to generate HTML documentation files from it, run doxygen Doxyfile and the html docs will be outputted into the docs subdirectory.
A few example programs come with this library and can be found in the examples subdirectory.
To build an example program, cd into its directory and simply run make.
If compilation complains about missing headers or undefined references, you will probably need to adjust the JSGF_KIT_LD and JSGF_KIT_CFLAGS variables in the Makefile to point to the correct library path and include directories (just run pkg-config --cflags jsgfkit and pkg-config --libs jsgfkit and copy the output in).
The original purpose of this program was to manipulate JSGF grammars for use with the CMU pocketsphinx toolkit, which has a built in JSGF parser that transforms JSGF grammars into finite state grammars (FSGs), but in the process the Tag unary operator is lost. These tags provide valuable context information when matching speaker/user input against command grammars, and this library solves the issue by allowing the program to match the resulting string from cmu sphinx against a grammar and returning the matching tags. This library also provides methods of easily manipulating grammars and dynamically generating them.
