Re^2: To Single Quote or to Double Quote

Funny - I do it exactly the opposite. I use singles unless I need double, because then interpolating happens only when I say so, and I otherwise don't have to pay attention to sigils or other special characters. When interpolation happens, then I have to scan the line to figure out if I want to go and escape everything, or if I leave it as-is, and use the concatentation operator '.'. As far as obviousness, I suggest a syntax-highlighting editor. ;-)

I second your recommendation to use a syntax-highlighting editor, but I want to expand. Not all editors (even fte, sadly, which I loved) handle complex quoting in Perl in a sane manner. For example, an editor might have trouble with some of: `qq[]; s///; y///; ##and so on, any with three separators s[][]; ##etc m,/,; ##non-standard matching, esp with a slash m/\//; #matching with an escaped version of a delimeter` [download] The only editor I've ever found that handles all of those correctly is SciTE. radiantmatrix `require General::Disclaimer; s//2fde04abe76c036c9074586c1/; while(m/(.)/g){print substr(' ,JPacehklnorstu',hex($1),1)}`	[reply] [d/l]

FYI - FTE handles all those just fine. It's not perfect, but those particular types are working currently. I've fixed many of the perl syntax highlighting problems in FTE, but I don't think any of those ever had a problem that I had to fix.	[reply]

My Windows editor of choice handles all of that just fine. I wish they made a Linux version. -- Linux, sci-fi, and Nat Torkington, all at Penguicon 3.0 perl -e 'print(map(chr,(0x4a,0x41,0x50,0x48,0xa)))'	[reply] [d/l]

I also lean toward sticking with 's. For the "only interpolate when I really mean it" reason as well as my probably unfounded fear of a performance hit on "s. Doug	[reply]
