This wiki is a reference for Grammar Matrix developers. Users of the Grammar Matrix should start from MatrixTop.

Several matrix.py commands (such as "install", "vivify", and "regression-test") require the environment variable CUSTOMIZATIONROOT to be set, with the value being the "gmcs" directory of the Matrix branch being used. In most cases this can, and should, be set as an option to matrix.py (--customizationroot (short form: -C)). For example:
python matrix.py --customizationroot=gmcs/ regression-test
python matrix.py -C gmcs/ regression-test
If necessary, the variable may be set with an export command, which would be valid for the current session. This export command may be placed in ~/.bashrc so the variable is set each time a session is started. Assuming the directory matrix/ exists is the home directory, the export commands would look like this for trunk:
or like this for a branch:
Additionally, if you are using ACE (AceTop) for regression testing or whatever, the variable may also be set with an export command. This export command may be placed in ~/.bashrc, too.
You can download the latest version of ACE here.
matrix.py is a top-level script used mainly by developers to do a wide range of tasks, such as customization, validation, unit-testing, regression-testing, and installing. The command python matrix.py --help prints the following (as of 2011.04.26):
Usage: matrix.py [OPTION] COMMAND [ARGS...] OPTIONS: --customizationroot (-C) PATH Set CUSTOMIZATIONROOT to PATH. --cheap-hack Add a blank morphological rule to irules.tdl (if it is empty) to workaround a bug in Cheap. --lkb Install the LKB binaries to a live site. --warning (-w) Print warnings when running validate. --help (-h) [COMMAND] Print a usage message about COMMAND (if specified) or else all commands and examples. COMMANDS: customize (c) PATH [DEST] Customize the grammar at PATH, with the output written to DEST or the directory at PATH. PATH points to a choices file or a directory that contains a choices file. customize-and-flop (cf) PATH [DEST] Customize and flop the grammar at PATH, with the output written to DEST or the directory at PATH. PATH points to a choices file or a directory that contains a choices file. validate (v) PATH Validate the choices file at PATH. regression-test [-TASK] [TESTS] Run regression test TASK (or all tasks if unsprecified) over TEST (or all tests if unspecified). TASKS can be any of the following and can be combined (e.g. -vc): [none] : run all tests -v : validate and report errors -c : customize and report errors -p : customize and parse, report differences with gold TESTS can be a single test name or a list of names. regression-test-add (ra) CHOICES TXTSUITE Add CHOICES (a choices file) and TXTSUITE (a text file containing test sentences) as a new regression test. Both CHOICES and TXTSUITE are filenames, not paths, and the respective files should exist in the scratch directory (gmcs/regression_tests/scratch/). regression-test-update (ru) TEST Update the gold standard of TEST to use the results of the current system. regression-test-remove (rr) TEST Remove TEST from the regression test suite. This command removes all files checked into subversion. regression-test-rename (rn) OLDTEST NEWTEST Rename OLDTEST to NEWTEST. This is performed with a call to 'svn mv' on the files in the repository. Remember to commit your changes. unit-test (u) Run all unit tests. web-test (w) Run all web tests. web-test-add (wa) PATH [comment] Add a new Selenium test with an optional comment. web-test-remove (wr) TEST Remove a Selenium test. install (i) PATH Install a custom instance of the Grammar Matrix Customization System and Questionnaire at PATH (PATH may be a URL for remote installs). install-homer (ih) PATH Install a custom instance of the Grammar Matrix Customization System and Questionnaire at the PATH specified on the default server (Homer). vivify (v) Install a new version of the Grammar Matrix Customization System and Questionnaire to the live site after verifying the code has been tested and committed to SVN. EXAMPLES: matrix.py customize ../choices/Finnish matrix.py c ../choices/Finnish matrix.py customize-and-flop ../choices/Finnish matrix.py cf ../choices/Finnish matrix.py validate ../choices/Finnish matrix.py v ../choices/Finnish matrix.py --customizationroot=gmcs/ regression-test matrix.py -C gmcs/ r -v matrix.py -C gmcs/ r -cp vso-aux-before-vp Fore matrix.py -C gmcs/ ra Cree_choices Cree_test_suite matrix.py -C gmcs/ ru Cree matrix.py -C gmcs/ rr tiniest matrix.py -C gmcs/ rn sujb-drop subj-drop matrix.py -C gmcs install local/dir matrix.py -C gmcs/ --lkb i email@example.com:~/public_html/my_matrix matrix.py -C gmcs/ install-homer my_matrix matrix.py -C gmcs/ --lkb ih my_matrix matrix.py -C gmcs/ vivify
If you get the repository using the command above, you will see three subdirectories: branches, tags, and trunk. Each of these contain a copy of the Matrix code (a "branch"), but "trunk" is the official version, "tags" contains frozen snapshots (e.g. the version used for a dissertation, etc.), and "branches" contains development versions. The directory structure detailed below explains the directories and files for a single branch (e.g. in trunk):
gmcs/ [most of the code resides here] lib/ [Python libraries for internal code] hierarchy.py [module for type hierarchies] tdlhierarchy.py [module for tdl hierarchies] itsdb.py [module for itsdb profile creation] linglib/ [Libraries for linguistic phenomena] tests/ [unit tests for linglib] agreement_features.py argument_optionality.py auxiliaries.py case.py coordination.py direct_inverse.py features.py lexbase.py [classes shared by lexicon.py and morphotactics.py] lexical_items.py [should probably be merged with lexicon.py] lexicon.py morphotactics.py negation.py parameters.py toolboximport.py verbal_features.py word_order.py yes_no_questions.py regression-tests/ [code and resources for regression testing] sql_profiles/ [code and resources for MatrixTDB] tests/ [unit tests for the general system] __init__.py [gmcs packaging module] choices.py [classes for working with choices files] customize.py [primary code for customizing grammars] def_check.py [module to check matrixdef] deffile.py [module to interpret matrixdef for web presentation] generate.py [module to aid in test-by-generation] profiles.py [MatrixTDB ... might be from old version] randgram.py [out-of-date script to create a semi-random grammar] tdl.py [module for dealing with TDL files] tdltest.py [code to test tdl.py. Should probably be folded into unit tests] utils.py [module with various helper functions] validate.py [module to validate a choices file] gmmt/ [resources for the "massively multilingual translation" task] lisp/ [various lisp scripts for Developers] matrix-core/ [the Matrix grammar files] modules/ [snippets of TDL and notes about analyses] web/ [place for web questionnaire related files] sample-choices/ [sample choices files displayed on the live site] templates/ [inputs for test-by-generation] matrix.css [style file for the questionnaire] matrixdef [website content definition] matrix.js [website-related functions] install [bash script for installing the code (e.g. to the live site)] matrix.py [Python script for running customize, tests, install, etc.] matrix.cgi [CGI script to handle web requests]
