GAP for Fedora
|
|
Based on "GAP for Debian" by Bill Allombert <ballombe@debian.org>
|
|
|
|
|
|
GAP (https://www.gap-system.org) is a system for computational discrete
|
|
algebra. Many add-on components ("packages") are available for GAP, most of
|
|
them not yet available from Fedora. However, they can be installed locally in
|
|
any of the following locations:
|
|
- /usr/share/gap/pkg
|
|
- /usr/lib/gap/pkg
|
|
- ~/gap/pkg
|
|
|
|
Some packages must be compiled. The necessary tools are available in the
|
|
gap-devel package.
|
|
|
|
Saved Workspaces, or How to make GAP start faster
|
|
-------------------------------------------------
|
|
|
|
GAP starts slowly because it needs to parse all the libraries installed at
|
|
start up. To make GAP start faster, it is possible to save the GAP workspace
|
|
and reload it at the next start up. To support this, Fedora provides a
|
|
Debian-derived script, update-gap-workspace; see the update-gap-workspace(1)
|
|
manual page.
|
|
|
|
Colors in the GAP shell
|
|
-----------------------
|
|
|
|
If you would like the GAP shell to display the prompt, input, etc. in color,
|
|
you can try colorprompt.g by Frank Lübeck. Add this line to ~/.gaprc:
|
|
|
|
ColorPrompt(true);
|
|
|
|
See /usr/lib/gap/lib/colorprompt.g for more information.
|
|
|
|
Browsing GAP Documentation
|
|
--------------------------
|
|
|
|
By default, GAP will display documentation in a terminal. Other options are
|
|
available. Insert one of the following into ~/.gaprc:
|
|
|
|
SetHelpViewer("firefox"); # Displays HTML documentation in Firefox
|
|
SetHelpViewer("konqueror"); # Displays HTML documentation in Konqueror
|
|
SetHelpViewer("lynx"); # Displays HTML documentation in Lynx
|
|
SetHelpViewer("w3m"); # Displays HTML documentation in w3m
|
|
SetHelpViewer("xdvi"); # Displays DVI documentation in xdvi
|
|
SetHelpViewer("xpdf"); # Displays PDF documentation in xpdf
|
|
SetHelpViewer("xdghtml"); # Displays HTML documentation using xdg-open
|
|
SetHelpViewer("xdgdvi"); # Displays DVI documentation using xdg-open
|
|
SetHelpViewer("xdgpdf"); # Displays PDF documentation using xdg-open
|
|
|
|
The last three are Fedora extensions. They use xdg-open to open the
|
|
documentation files with the user's preferred applications.
|
|
|
|
Large GAP libraries are compressed
|
|
----------------------------------
|
|
|
|
To save disk space, the largest GAP libraries are compressed with gzip. GAP
|
|
automatically decompresses them.
|
|
|
|
Supporting GAP
|
|
--------------
|
|
|
|
If you use GAP, please send a short note to support@gap-system.org stating you
|
|
use the Fedora packages of GAP so the GAP team can keep track of the number of
|
|
GAP users. This helps them obtain funding for the project.
