[GAP Forum] Accessing source code from GAP folder

[Benjamin Sambale]

Dear Sugandha,

under linux you can use "grep" in the GAP root dir. For instance:

grep -ir --include=*.gi 'WedderburnDecomposition'

output:
pkg/wedderga-4.10.0/lib/div-alg.gi:# Given a simple algebra output by 
WedderburnDecompositionInfo
pkg/wedderga-4.10.0/lib/div-alg.gi:# this fixes the bug created by the 
new WedderburnDecompositionInfo
pkg/wedderga-4.10.0/lib/div-alg.gi:# 
WedderburnDecompositionByCharacterDescent(K,G);
pkg/wedderga-4.10.0/lib/div-alg.gi:InstallGlobalFunction( 
WedderburnDecompositionByCharacterDescent, function(F,G)
pkg/wedderga-4.10.0/lib/div-alg.gi:# "WedderburnDecompositionInfo" 
output has 4 terms, the next
pkg/wedderga-4.10.0/lib/div-alg.gi:# WedderburnDecompositionInfo in 
wedderga has length 4,
pkg/wedderga-4.10.0/lib/div-alg.gi:InstallGlobalFunction( 
WedderburnDecompositionWithDivAlgParts, function(R)
pkg/wedderga-4.10.0/lib/div-alg.gi:W:=WedderburnDecompositionInfo(R);
pkg/wedderga-4.10.0/lib/div-alg.gi:InstallGlobalFunction( 
WedderburnDecompositionAsSCAlgebras, function(R)
pkg/wedderga-4.10.0/lib/div-alg.gi:W:=WedderburnDecompositionInfo(R);
pkg/wedderga-4.10.0/lib/main.gi:#O WedderburnDecomposition( FG )
pkg/wedderga-4.10.0/lib/main.gi:## result as an attribute of FG. 
WedderburnDecomposition uses the attributes
pkg/wedderga-4.10.0/lib/main.gi:## The reason for such combination of 
operation 'WedderburnDecomposition' and
pkg/wedderga-4.10.0/lib/main.gi:InstallMethod( WedderburnDecomposition,
pkg/wedderga-4.10.0/lib/main.gi:Info( InfoWedderga, 2, "Info version : 
", WedderburnDecompositionInfo( FG ) );
pkg/wedderga-4.10.0/lib/main.gi:#A WedderburnDecomposition( FG )
pkg/wedderga-4.10.0/lib/main.gi:InstallMethod( WedderburnDecomposition,
pkg/wedderga-4.10.0/lib/main.gi:Info( InfoWedderga, 2, "Info version :

pkg/wedderga-4.10.0/lib/main.gi:InstallMethod( 
WedderburnDecompositionInfo ,
