3. Global Variables

3.1 An InfoClass for debug purpose

3.1-1 InfoPolymaking
> InfoPolymaking( info class )

If set to at least 2, the output of polymake is shown. At level 1, warnings are shown. This is the default. And at level 0, the polymake package remains silent.

3.2 Variables for system interaction

The variables for interaction with the system are contained in the file environment.gi. Each of these variables has a function to set it, see 1.2. If POLYMAKE_COMMAND or POLYMAKE_DATA_DIR are set at startup, they are not overwritten. So if you don't want (or don't have the rights) to modify environment.gi, you can set the variables in your .gaprc file.

3.2-1 POLYMAKE_COMMAND
> POLYMAKE_COMMAND( global variable )

This variable should contain the name of the polymake program in the form as returned by Filename So a probable value is Filename(Directory("/usr/local/bin"),"polymake").

3.2-2 POLYMAKE_DATA_DIR
> POLYMAKE_DATA_DIR( global variable )

In this directory the files for polymake will be created. By default, this generates a temporary directory using DirectoryTemporary
