"toric" is a package that implements some computations related to toric varieties and combinatorial geometry in GAP. With "toric", affine toric varieties can be created and related information about them can be calculated. "toric" is written entirely in the GAP language by D. Joyner.
This package is licensed under the MIT license.
To install "toric" (as a GAP 4 Package) unpack the archive file in a
directory in the pkg hierarchy of your version of GAP4. (This might be
the pkg directory of the GAP 4 home directory.) On a *nix system, this
is accomplished by (1) copying toric.tar.gz into the pkg subdirectory,
(2) typing (as root, if necessary) tar zxvf toric.tar.gz.
After starting up GAP, the "toric" package needs to be loaded. Load "toric" by typing at the GAP prompt:
gap> LoadPackage( "toric" );
If "toric" isn't already in memory, it is loaded and a small banner is displayed.
Please submit bug reports via https://github.com/gap-packages/toric/issues. Alternatively, you can also send an email to support@gap-system.org.
In either case, remember we will need to be able to reproduce the problem; so please include:
- The version of GAP you are using; either look at the header when you start up GAP, or at the gap> prompt type: VERSION;
- The operating system you are using e.g. Linux, Mac OS X, Windows, ...
- A script that demonstrates the bug, along with a description of why it's a bug (e.g. by adding comments to the script - recall comments in GAP begin with a #).
