My moderation project consists of a json to xml interpreter called jxml written using Flex and Bison, as well as a paper with analysis.
Flex and Bison are required to build jxml. It is probably easiest to install them using your distro's builtin package manager. Flex's source code is here, and Bison's is here.
After Flex and Bison are installed, building is easy:
makewill create the executable jxml in the build directory, along with the lexer and parser files json_xml.yy.c, json_xml.tab.c, and json_xml.tab.h.
To run, simply type:
./jxmlThis will give you a REPL to put JSON in. For example:
./
{"Person" : { "Last Name" : "Furr", "First Name" : "Samuel"}}
<Person><Last Name>Furr</Last Name><First Name>Samuel</First Name></Person>The test harness is a perl script called jxml_test.pl. To run the script, you will need perl and the Text::Diff module, which can be installed from CPAN. You will also need to install Valgrind. You can find Perl, Text::Diff, and Valgrind here, here, and here respectively. It is probably easiest to install all of them using your distro's builtin package manager.
To use the test harness, you can run make test to run all tests. Depending on the number of tests installed this may take a while, since memory tests are included. To only run I/O correctness tests, run perl jxml_test.pl. To run memory tests as well run perl jxml_test.pl.
Only a few tests are included. To add new tests, you must add a test file, n, with the name t<n> containing the input you would like to test (don't forget the newline at the end of the file!) to the tests directory. You must also add an expectation file with the same name containing the expected output (don't forget the newline at the end of the file!) to the tests/exp directory. The results of your tests will be in tests/res. Results are removed every time you run make test.
My moderation paper can be found in the folder paper. The file is called jxml.pdf. I've also included the LaTeX and bibliography source files in the folder. I've also included my lab5 JSON to XML interpreter for comparison. It is called lab5b.rkt
