hi i have a sprintf which uses a scalar as its format:
my $Bformat = "%1\$s16-> %2\$s16 %3\$s16 %4\$s16 %5\$s16 %6\$s16-> %7\$s16
%8\$s16"
what i would like to do is generate a new format for the sprintf by doing
permutations of 5 arrays like this:
my @phraseA = qw( %1\$s16-> %2\$s16-> %3\$s16-> );
my @phraseB = qw( %4\$s16 %5\$s16 %6\$s16-> );
my @phraseC = qw( %7\$s16 %8\$s16 %9\$s16 );
my @phraseD = qw( %10\$s16-> %11\$s16 %12\$s16 );
my @phraseE = qw( %13\$s16 %14\$s16 %15\$s16-> );
my @phrasegroup = ([...@phrasea], [...@phraseb], [...@phrasec], [...@phrased],
[...@phrasee]);
my @phraseperm = map {...@$_} permute(@phrasegroup);
#flatten permutation array
my @Bformat = map { @$_ } @phraseperm;
but when i do this i get :
Invalid conversion in sprintf: "%\" at score-generator11.pl line 53.
so i thought maybe i needed to turn the array into a scalar:
#my $test = join(" ",@Bformat);
but that gave the same error
any ideas what i am doing wrong?
Strings like '%1\$s16->' are not valid sprintf/printf formats. What
does your data look like and what do you expect it to look like after
using sprintf?
