Re^2: simplifying substitution

Maybe my perl version is different, but I can never get away with using actual spaces like that on the match side--I'd have to represent them...something like this:

$all =~ s/([ ]{2}[1-9][0-9])[ ]/$1\t\t/g;

If running strictly on English and there were no possibilities or no issue with encountering numbers like '04' which had to be handled differently, the code could be a mite simpler:

$all =~ s/([ ]{2}\d\d)[ ]/$1\t\t/g;

Blessings,

Without the /x modifier, a space should match literally. What's the output of `perl -lwe 'print qq( $]) =~ s/ /v/r'` [download] (use double quotes instead on MSWin) `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

I get this output from that command (I'm not on Windows): `Bareword found where operator expected at -e line 1, near "s/ /v/r" Unquoted string "r" may clash with future reserved word at -e line 1. Can't modify string in substitution (s///) at -e line 1, near "s/ /v/r " syntax error at -e line 1, near "s/ /v/r " Execution of -e aborted due to compilation errors.` [download] When I check the version, I get this: `perl -v This is perl 5, version 12, subversion 4 (v5.12.4) built for darwin-th +read-multi-2level (with 2 registered patches, see perl -V for more detail) Copyright 1987-2010, Larry Wall` [download] Blessings, ~Polyglot~	[reply] [d/l] [select]

OK, 5.12 doesn't have /r. So what about `perl -lwe '$v = qq( $]); $v =~ s/ /v/; print $v'` [download] `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

Thanks to all of you, for your contributions! Since my script will be dealing strictly with English text, I decided to try "$all =~ s/( {2}\d\d) /$1\t\t/g;" first, and it seems to do the trick! Aloha, and stay safe!	[reply]
