gshell is an interactive utility for testing morphological rules. The gshell interpreter and GFramework library are implemented in Perl. Copyright © 2003-2008 The Sanskrit Library.

Development of this software has been supported by NSF grant IIS-0535207. The current version of GFramework is 2.7.

Installation and prerequisites
GFramework requires the Expat XML parser and the XML::Parser library from CPAN. If you would like interactive input editing facilities (cf. man readline), you should install the GNU Readline Library as well as Term::ReadLine::Gnu. (But gshell can be used without the readline facility.) Perl libraries can be installed using the CPAN module (see man 3 CPAN). If you're using Mac OS X, you may find it convenient to use Fink to install the system libraries (assuming the normal Fink installation in /sw/bin, you can do sudo /sw/bin/fink install expat; sudo /sw/bin/fink install readline). If you use Fink to install libraries under /sw, you will need to configure the Perl modules for the appropriate library paths (for XML::Parser, perl Makefile.PL --includedir=/sw/include --libdir=/sw/lib; for Term::ReadLine::Gnu, perl Makefile.PL EXPATLIBPATH=/sw/lib EXPATINCPATH=/sw/include).
If GFramework.pm is not installed in the same directory as gshell.pl, it must be installed in a directory listed in @INC (you can indicate the location with the -I switch to perl).

Command summary
The following commands (which may be abbreviated, provided the abbreviation is not ambiguous) are available in gshell:
| command | arguments | description |
|---|---|---|
| bye | quit the shell | |
| conjugate | STEM ROOT MORPHID LEXID | conjugate the verbal STEM for the paradigm including MORPHID; STEM is a valid STEM of ROOT with the lexical identification LEXID |
| decline | STEM GENDER [LEXID] | decline the nominal STEM for GENDER (m, f, or n); if LEXID is not specified, assume that the STEM is a noun stem |
| describe | OBJECT | describe the named macro, mapping, function, or ruleset |
| help | provide a brief list of valid commands | |
| history | MORPHID | display the derivational history of the form with MORPHID in the most recently generated paradigm |
| load | FILE | load and parse the specified grammatical specification in XML format |
| steps | display the rulesets used in the generation of the previous paradigm |
