RegEx Tutorial?

Ruby
1

I looked through the archives, but couldn’t find a comprehensive
tutorial on regular expressions – could someone please point me to
one?

Specifically, I’m looking to extract all the words from a string that
are capitalized, but can’t find case-based match operators.

Thanks,

Siddarth

This one gives a good overview and
samplehttp://rubylearning.com/satishtalim/ruby_regular_expressions.html
This one provides a list of common
expressionshttp://www.rubyist.net/~slagell/ruby/regexp.html
Here is a tester for your ruby regular expressions.http://rubular.com/
Hope this helps

To test regular expressions (and with a handy little regex reference at
the bottom), use rubular: http://rubular.com/
And for your particular issue, try this:
str = “this Is Some test String eh?” cap_words = str.scan(/[A-Z]\w+/)

Sounds like you are using the proposed regex. Why don’t you go to the
given
site (rubular), put in “javaVariable”, and see if it gives you what you
expect.

If not, here is a decent explanation of the different things you could
do to

Nope, I edited the regex to account for spaces.

Not exactly a tutorial but a very comprehensive book on the matter is
“Mastering regular expressions”.

Kind regards
