Is there a Ruby tool or editor plugin that will convert an array literal into a %w array literal?
ARRAY = [
"Foo",
"Bar",
"Baz"
]
ARRAY = %w(
Foo
Bar
Baz
)
I know I could write my own regex to do this, but I'm hoping for something off-the-shelf. I'm already using Rubocop as a linter, but it doesn't cover it. I can't seem to find a plugin for RubyMine, Sublime, or Atom for it either.
You can use rubocop -a to autocorrect offenses. One of the default cops is the word array cop, which should have you covered.

Is there a simple gem I could install to show email-addresses in HTML-views only in an obfuscated way?
It would be perfect, if the email-addresses were converted into images.
If that is not possible, a simple replace of the # with "-at-"?
Or how could I use the solution from this thread:
How to protect my e-mail address from spambots
Whats wrong in using sub or gsub to achieve the same
"example#example.com".sub("#","-at-") #=> example-at-example.com
"example#example.org".sub("#","{at}") #=> example{at}example.org

I am a visual kind of guy and would like to know if there is somewhere a nice big overview of Ruby. You know, like a reference poster, with object hierarchy, most common methods, etc, all in color, layed out nice and clearly...
To a beginner like me would this would be awesome...
Is there something like that out there that you use or have stumbled upon?
Check these out :

I am looking for example uses (or tutorials) of the record library
http://www.cs.fit.edu/~pkc/classes/ai/swi-prolog/Manual/record.html
for SWI-prolog that I can use as a template. Do you have any pointers?
Thanks,
SetJmp
There is one example of usage here in the SWI-Prolog JSON library to hold JSON options
http://www.swi-prolog.org/git/packages/http.git/blob/HEAD:/json.pl
It is pretty straightforward to use. the only pain is that you can't pull arbitrary fields off a record because they need to be accessed by _(X). Also, i do not believe any extra meta-data about the record is stored in case you want to get the field names at run time.

I'd like a cheetsheet that contains the most common keywords and syntax, all contained on a single pdf page.

I had this hanging on my wall for a while.
I like "101 LINQ Samples" from [MSDN].

I'm looking for a boo syntax sheet/reference card. A quick search on google and on boo's site didn't turn up anything, does anyone know where one is?
I'm not aware of an online reference card, but perhaps this might be close enough?

This summary is concise and has useful links, although it looks like the author got bored half way through.
