Matrix Development

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

Below we have information about the SVN repository, configuration, the directory structure, and other links.

A collection of documentation regarding the Matrix project, aimed at Matrix developers.

Matrix Repository

svn co svn:// matrix

Several 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 (--customizationroot (short form: -C)). For example:

python --customizationroot=gmcs/ regression-test


python -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:

export CUSTOMIZATIONROOT=~/matrix/trunk/gmcs

or like this for a branch:

export CUSTOMIZATIONROOT=~/matrix/branches/mybranch/gmcs


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. 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 --help prints the following (as of 2011.04.26):


    --customizationroot (-C) PATH
                Set CUSTOMIZATIONROOT to PATH.
                Add a blank morphological rule to irules.tdl (if it is
                empty) to workaround a bug in Cheap.
                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.
    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
    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.

Directory Structure

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):
