"spacers" in regexs between variables?

[Brett_Tabke]

$test ="foo";
$bar ="bar";
$test =~ s/fuubar/$testYes$bar/gi

See how $test runs on into "Yes" in the replacement? That's going to be interpreted as a variable with the name "$testYes" instead of $test + "Yes".

What do you use for a spacer to get that interpreted right?

Good question. I never ran into this problem but would be interested in a better answer. The only way I know how to do it is:

$test ="foo";
$bar ="bar";
$_ = "".$test."yes".$bar."";
$test =~ s/fuubar/$_/gi;

Or change one of the variables name.

Simplest way is with the 'e' modifier, plus periods:

$test =~ s/fuubar/$test.Yes.$bar/gie;

The e modifier indicates that the second half of the regex should be evaluated as a perl expression, so in this case the periods are interpreted as 'concatenation' characters - effectively they become spacers.

Brett, just escape the 'Y' (works in most cases)

s/fuubar/$test\Yes$bar/gi;

Well that's it. Thanks Danny.

That works ok netcommer for about 15 out of 26 characters. (eg \n \t...)

like I said...most cases... ;)
