11 Obsolete functions

11.1 Operations from AutoDoc

The file functions FindMatchingFiles and CreateDirIfMissing were copied from package AutoDoc where they are named AutoDoc_FindMatchingFiles and AutoDoc_CreateDirIfMissing.

The string function StringDotSuffix was also copied from package AutoDoc, where it is named AUTODOC_GetSuffix.

The function SetIfMissing was also transferred from package AutoDoc, where it is called AUTODOC_SetIfMissing. It writes into a record provided the position is not yet bound.

As from version 0.61, all these functions became obsolete in Utils, but continue to be defined in AutoDoc.

11.2 Functions for printing

The function PrintOneItemPerLine was used to prints lists vertically, rather than horizontally. Since a very similar result may be achieved using the GAP library functions Perform and Display, this function became obsolete in version 0.61.

gap> s3 := SymmetricGroup( 3 );; 
gap> L := KnownPropertiesOfObject( GeneratorsOfGroup( s3 ) );;
gap> Perform( L, Display );
IsFinite
IsSmallList
IsGeneratorsOfMagmaWithInverses
IsGeneratorsOfSemigroup
IsSubsetLocallyFiniteGroup
gap> Perform( s3, Display ); 
()
(2,3)
(1,3)
(1,3,2)
(1,2,3)
(1,2)

11.3 Other obsolete functions

11.3-1 Applicable Methods

The function PrintApplicableMethod, which was included in versions from 0.41 to 0.58, has been removed since it was considered superfluous. The example shows how to print out a function.

gap> ApplicableMethod( IsCyclic, [ Group((1,2,3),(4,5)) ], 1, 1 );
#I  Searching Method for IsCyclic with 1 arguments:
#I  Total: 7 entries
#I  Method 4: ``IsCyclic'' at /Applications/gap/gap4r9/lib/grp.gi:30 , value: 
36
function( G ) ... end
gap> Print( last );
function ( G )
    if Length( GeneratorsOfGroup( G ) ) = 1 then
        return true;
    else
        TryNextMethod();
    fi;
    return;
end
gap> ApplicableMethod( IsCyclic, [ Group((1,2,3),(4,5)) ], 0, 3 );
function( <1 unnamed arguments> ) ... end
gap> Print( last );                                               
function ( <<arg-1>> )
    <<compiled GAP code from GAPROOT/lib/oper1.g:578>>
end

11.3-2 ExponentOfPrime

The function ExponentOfPrime was originally transferred from package RCWA. The command ExponentOfPrime(n,p) returned the exponent of the prime p in the prime factorization of n.

Since the GAP function PValuation produces the same results, and does so more quickly, this function has been made obsolete.
