Jeffrey’s Exif viewer: a great non-regex thing on (:

Posted by jpluimers on 2013/09/19

You’d think that the site only has information on Jeffrey Friedl’s Mastering Regular Expressions (a great book on RegEx programming) MRE2 Errata,  MRE3 Errata and Where to get egrep (agrep and sourcecode/binary builds).

Not so (:

It also hosts a few other things, mostly having to do with imagery or photography:

.NET regular expressions classic: to compile or not to compile?

Posted by jpluimers on 2013/01/01

Every time I use regular expressions (or post about them), it makes me think about the classic RegEx post by Jeff Atwood: to compile or not to compile.

BTW: Happy 2013!

which kind of IsHex() function do you like most, and why?

Posted by jpluimers on 2012/07/10

Though the sample question is in C#, it applies to almost any language and framework: for relatively simple checks like IsHex(), you can go the RegEx way, or the compound if-statement way.

Which kind of function do you like most?

I’m not only interested in the percentages, so let me know in the comments why.


PS: if you want to use RegEx in .NET, you can compile them to IL, but be very cautious for the compilation overhead.
