Re: Handling escapes while splitting lines

mikecarlton,
I tend to use split when I am trying to split.

my $string = 'a\:b:c';
my ($key, $val) = split /(?<!\\):/, $string, 2;
print "$key, $val\n";

Of course you then need to remove the escape characters from the resulting strings, but I left that as an excersise for the reader.

I don't think that will work correctly if the last character of the key is an escaped backslash. That is, `my $string = 'a\\\\:b:c';` [download] The key should be '`a\`' and the value '`b:c`' (after removing escapes), but you'll end up with '`a\:b`' and '`c`'.	[reply] [d/l] [select]

Eimi Metamorphoumai, Right you are. This is one of those confessions I need to make. It frustrates me when people respond to my post without having read it closely enough to see that their reply is not applicable and yet I have done the same thing here. I completely missed the part about a double backslash being a literal backslash. I was thinking that the only thing that could be escaped was the colon. Thanks for correcting me and reminding me the importance of reading carefully. Cheers - L~R	[reply]
