camelize

[Sijo k g]

Hi
I would like to get output as "Re-Open" for the input "re-open"
And I tried
"re-open".camelize => "Re-open"

Could you please tell how can I do this?


Thanks in advance
Sijo

Hi,

Try:

"re-open".titleize.gsub(' ', '-')

(Assuming this is running in an environment that has Rails'
ActiveSupport library loaded).

Cheers,

You do know that "re-open" isn't correct English (it should be
"reopen"), and that "Re-Open" is arguably incorrect capitalization,
right?

Thanks in advance

Phrogz,

What does the "i" do in
gsub(/\b[a-z]/i){ |x| x.upcase }
do?

I took it out and the pattern seemed to work.

It makes the regex case-insensitive.

If you're asking that kind of question, you need to go read Programming
Ruby.

It's on my desk and I am constantly reading it. I could not, and
still cannot, find where that is defined.

This is probably the 20th regular expression syntax that I have had to
learn. It gets old.

In the section on regular expressions, IIRC.

/i is the same in Perl, and in most other regex syntaxes like it.

Anyway, if you're going to use a language, you need to learn the syntax
-- no excuses. Sure it gets old, but so does using an out-of-date
language because you didn't bother to learn a new one.

It's on page 320.

Just for the record ... I did look before I posted the question ... I
just couldn't find it.

Good to know. I use the Web edition, so I don't have page numbers.

OK.
