SYNOPSIS
gap [,OPTIONS/] [,FILES/]DESCRIPTION
GAP is a system for computational discrete algebra, with particular emphasis on Computational Group Theory. GAP provides a programming language, a library of thousands of functions implementing algebraic algorithms written in the GAP language as well as large data libraries of algebraic objects. GAP is used in research and teaching for studying groups and their representations, rings, vector spaces, algebras, combinatorial structures, and more.- -h, --help
- print this help and exit
- -b, --banner
- disable/enable the banner
- -q, --quiet
- enable/disable quiet mode
- -e
- disable/enable quitting on <ctr>-D
- -f
- force line editing
- -n
- prevent line editing
- -E, --readline
- disable/enable use of readline library (if possible)
- -x, --width
- <num> set line width
- -y, --lines
- <num> set number of lines
- -g, --gasinfo
- show GASMAN messages (full/all/no garbage collections)
- -m, --minworkspace <mem>
- set the initial workspace size
- -o, --maxworkspace <mem>
- set hint for maximal workspace size (GAP may allocate more)
- -K, --limitworkspace <mem>
- set maximal workspace size (GAP never allocates more)
- -c
- <mem> set the cache size value
- -s
- <mem set the initially mapped virtual memory
- -a
- <mem> set amount to pre-malloc-ate postfix 'k' = *1024, 'm' = *1024*1024, 'g' = *1024*1024*1024
- -l, --roots
- <paths> set the GAP root paths Directories are separated using ';'. Putting ';' on the start/end of list appends directories to the end/start of existing list of root paths
- -r
- disable/enable user GAP root dir GAPInfo.UserGapRoot
- -A
- disable/enable autoloading of suggested GAP packages
- -B
- <name> current architecture
- -D
- enable/disable debugging the loading of files
- -M
- disable/enable loading of compiled modules
- -N
- unused, for backward compatibility only
- -O
- disable/enable loading of obsolete files
- -X
- enable/disable CRC checking for compiled modules
- -T
- disable/enable break loop
- -i
- <file> change the name of the init file
- -L
- <file> restore a saved workspace
- -R
- prevent restoring of workspace (ignoring -L)
- -p
- enable/disable package output mode
- --prof
- <file> Run ProfileLineByLine(<filename>) on GAP start
- --cover
- <file> Run CoverageLineByLine(<filename>) on GAP start
- Boolean options (b,q,e,r,A,D,E,M,N,T,X,Y) toggle the current value each time they are called. Default actions are indicated first.
