It would be nice to be able to get a regexes string back

ruby-talk
1

class Decoder

FOO = %r{foo}
BAR = %r{bar}

FOOBAR = %r{#{FOO.regex}|#{BAR.regex}}

…

I’m having to do

FOO = ‘foo’

RE_FOO = %r{FOO}

So I can use the regex bits in other regexes, and as regexes themselves.

I’d love any suggestions on a nicer way to do this!

Thanks,
Sam

 Returns the original string of the pattern.
    /ab+c/ix.source   #=> "ab+c"

Thats funny! I did a ri Regex and looked at the methods that looked
promissing, but “source” means to do a run-time evaluation, in my
mind, I never even read the docs for this method…

Thanks,

I have occasionally thought it would be nice to be able to see the doc
for all methods for a given module/class, to avoid this type of random
“that can’t be it” hunting :slight_smile:

You’ll get it soonish. Core classes are being RDoc’ed, so method
browsing is a viable option.
