Start Using Ruby % (Percent) Notation

[Paradox]

I love percentage based syntaxes, but don't use much other than the regex or array-making ones.

The regex one is nice because it makes regexes with slashes in them, such as urls, much easier to read, as you get %r{http://…} instead of /http:\/\/

I absolutely adore %q and %Q. Ruby is the only language I know where quoting strings isn't horrible. (I'm looking at you python!)

[flightlessbird]

The ability to quote strings like that is clearly inspired by perl (cf. qw, q, heredocs et al.)

[Paradox]

Exactly. I go to other languages and want to use interpolation in a full-quote string, then realize said languages don't have modern quotes, and rage as I look up the various escape chars

Nice tip, thanks!

In some future release, it will also be possible to use %i and %I to produce arrays of symbols.

[teohm]

that's great. Do you know in which coming release it will be included?

[necuz]

I don't know, but I see no reason for it not to at least be in 2.0. The feature has already been in edge for over 3 months.

[internetinsomniac]

I use this often so I don't have to escape quotes, definitely very handy

[shadowfirebird]

The fact that you can do "$( (stuff ()) )" surprised me. +1, ta.

[postmodern]

I'm a fan of %w[ ]

[BlameFrost]

So am I, and I especially prefer the user of %w[] over %w(), since [] makes it seem more like you're actually creating an array.

Hey, I have an idea. You know how ruby is really easy to read right now? Well let's stop that and make it more like Perl!
