Question

I’m working on a website where I have some text which I am using the RedCloth gem to markdown. basically I need to intercept some text before it gets to the gem, and parse the text with a colour code syntax gem. My regex is very poor (and I don’t know if I can do this.) I need to select chucks of text and parse them before RedCloth gets ahold of it.

example text

I need to select (in ruby) the chucks of text that start with ##code(language) and end with #code, I also need to know what is inside of the bracket at the start tag ##code(in-here)

other text.....

##code(ruby)

puts "Hello World"

##code

more text.......


##code(c++)

#include <string>
#include "logger.h"

##code

etc...

any help would be greatly appreciated.

Thanks
Phil.

Answer 1

This should work for you:

/##code\((\S+)\)(.+?)##code/m

That’ll match any non-space character, so as long as your (language) stuff doesn’t have spaces, you’ll be good to go.
