NAME

gap - Run the Groups, Algorithms and Programming system 

SYNOPSIS

gap[OPTIONS] [FILES] 

DESCRIPTION

GAP is a system for computational discrete algebra, with particular emphasison Computational Group Theory. GAP provides a programming language, a libraryof thousands of functions implementing algebraic algorithms written in the GAPlanguage as well as large data libraries of algebraic objects. GAP is used inresearch and teaching for studying groups and their representations, rings,vector spaces, algebras, combinatorial structures, and more. 

OPTIONS

Boolean options (b, e, p, q, r, A, D, M, N, O, T, X, and Y) toggle the currentvalue each time they are used. Default actions are indicated first.

MEM options indicate a number of bytes. Larger units are indicated withtrailing characters: 'k' for kilobytes, m for megabytes, and g for gigabytes.For example, '512k' means 512 kilobytes.

-a MEM
Set the amount of preallocated space.
-b
Disable/enable the banner.
-c MEM
Set the cache size.
-e
Disable/enable quitting on Ctrl-D.
-f
Force line editing.
-g
Show GASMAN messages. If this option is given once, then full garbagecollections are shown. If it is given twice, all garbage collections areshown.
-h
Print a help message and exit.
-i FILE
Load an alternate init file.
-l PATHS
Set the GAP root paths. A leading semicolon means to append PATHS to theexisting list of root paths. A trailing semicolon means to prepend PATHS.Otherwise, the list of root paths is replaced with PATHS.
-m MEM
Set the initial workspace size.
-n
Prevent line editing.
-o MEM
Set the hint for the maximal workspace size. GAP may allocate more.
-p
Enable/disable emitting extra commands to the output to tell a window handlerwhat GAP is doing.
-q
Enable/disable quiet mode.
-r
Disable/enable reading of the .gaprc file.
-x NUM
Set the window width to NUM columns.
-y NUM
Set the window height to NUM rows.
-A
Disable/enable autoloading of GAP packages.
-B NAME
Set the name of the current architecture.
-C <output> <input> <name>
Compile an input file with the given name into an output file.
-D
Enable/disable debugging the loading of library files.
-K MEM
Set the maximal workspace size. GAP never allocates more.
-L FILE
Restore a saved workspace.
-M
Disable/enable loading of compiled modules.
-N
Disable/enable check for completion files.
-O
Enable/disable compatibility with GAP 3, by causing false and fail to be thesame value.
-R
Prevent restoring of workspace (causes -L to be ignored).
-T
Disable/enable break loop.
-U OPTIONS
Set the compile options for compiling GAP files.
-X
Enable/disable CRC while reading completion.
-Y
Enable/disable CRC while completing files.
