i got a neat question..

i'm reading a conf file, splitting it up into key val pairs ti put into a hash. this sub is some'pin like..

sub conf2hash {
    my %argv = @_;
    
=pod
    usage:    
    conf2hash( file=>'path/2/file', hashref=> \%yourhash, splitchar=>'
+=', commentchar=> '#');
    if splitchar is null, default is = sign
    if commentchar is null, default is # mark

    # one key val pair per line
    # returns 0 on errors
=cut

    defined $argv{splitchar} or $argv{splitchar}='=';
    defined $argv{hashref} or return 0;
    defined $argv{commentchar} or $argv{commentchar}='#';
    defined $argv{file} or return 0;

    open (IN, "< $argv{file}") or die($!);
    while (<IN>) {
    
        if ( $_=~m/^$argv{commentchar}|^\s+$/ ) { next;}
        $_=~s/\s//g;
        
        my @a = split(/$argv{splitchar}/,$_);
        ${$argv{hashref}}{$a[0]}=$a[1];        
    }
    close IN;
    return 1;
}

An example conf file... 
THIS=that
name=joe
height=heyman

#this is a comment
age=14

Here's my question... where i read in the line and then split it.. 

my @a = split(/$argv{splitchar}/,$_);
#and then, place it into the hash....
${$argv{hashref}}{$a[0]}=$a[1];

[download]

isn't there some other way to do this like...

split(/$argv{splitchar}/,$_);
${$argv{hashref}}{$_[0]}=$_[1];

# is that ok ??

# and what about some thing like..
# (and I DONT KNOW the syntax, that's why im here!!)
( ${$argv{hashref}}{$_} = $_ )=  split(/$argv{splitchar}/,$_);  

#is that totally making it up ?

any code shortcuts ?:)
