Re: [flexcoders] AS3 :: Multiline RegExp declarations :: Future enhancement ? ;-)
Darron,
If it's a concern, then when you build your regex don't escape the \'s,
and as a last step before you convert them to strings just do a quick
find/replace with \ to \\ on the regex.
convert them to strings ... ?
I am back into the easy bake oven and burned myself.
Are you saying when I write a regexp as a string? Then do a replace on them?
The problem is, once you even write a string, it converts them. So it's
like the chicken-egg thing. I can't even get the string to a point
where I could do this. The string literal allready baked the backslash
out.
Ok, I am done wasting time, back to the double backslashes until Adobe makes multiline regexp for me. ;-)
PS, There seems to be this notion in my mid that I am completly
missunderstanding you, if this is the case could you clarify for me? If
so, everything I wrote means nothing :)
Peace, Mike

Doh, really? I've actually been using it a decent amount. It's
especially handy in testing the SHA1 hash of a million letter a's to verify the
hash algorithm is correct:
var millionAs:StringBuilder = new StringBuilder
( '' );
millionAs.ensureCapacity(
100 );
for ( var i:
int = 0; i 100
; i++ ) {
millionAs.append(
'a' );
}assertSHA1( millionAs.
toString(), 34aa973cd4c4daa4f61eeb2bdbad27316534016f
);
I realize the above loop could be unrolled to make it perform even faster (by
appending more 'a's in each append call, and reducing the number of iterations
by 10x, 100x, etc). But StringBuilder in this case was a lot faster than
using a regular string.. though, I imagine this isn't really a typical
use-case.
That said, however, it would be a shame to see StringBuilder go -- especially
after having written a decent number of pages for it for an upcoming
book. Can I petition? :-)

Ah, are you talking about the code panes find/replace?
Heh, I won't goto that trouble, I can see myself really messing things up!

Yeah, Well.. The only reason I don't like using the string is the esacped back slash sequences. This is a chunck btw, I am using strings. ?var\\s([a-zA-Z_]+)\\s?:?\\s?([a-zA-Z_]+)(\\s?=\\s?(.*))?;?

+= is much improved from when we needed
StringBuilder earlier in the cycle. The gains of StringBuilder were reduced to
a very limited number of cases and it was decided that the amount of Player
code required along with testing just didnt make it worthwhile. Were
still investigating to make sure that some of our stuff didnt degrade
but its likely that well fix the String class rather than
re-introduce StringBuilder if there are problems.

Darron, blush...
If you looked at my php implementation(my as2 doc generator) it had all
that plus some hex stuff. I was using this as a test parsing and I
never use dollar signs, slipped my mind.
Thanks for reminding me ;-)
And for that first idea, haha great!!! Man 4 eyes are better than 2!
