Re^2: logic within interpolation

in reply to Re: logic within interpolation
in thread logic within interpolation

the problem actually lies in the 'nesting' of the interpolations being done.

${if(this){return 'this';}} is fine, because the single quotes do not result in this during eval:

eval ""this""; <- problem.

eval "'this'"; <- evaluated properly.

So the problem is I need to find a way to interpolate the contents of $1 and *then* have those contents interpolated again. I think I'm on the right track now, but thanks for the boilerplate, some of that looks to be useful reading.

For the evil and functional version of what you say, see Re: Perl as a command executor (with hash variable substitution). And then use the modules cited above. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply]

do you want to do this? `eval "qq{$interpol}"`	[reply] [d/l]
