How to match this(83085640) number from text above by ruby regex ? The Start of regex must be after showPhoto(' text and ends at this point _ after numbers
Please help!
You simply need to do the following:
my_text = "showPhoto('83085640_283973341',"; #Input string. I'm only using a part of it here for convenience.
pat = /showPhoto\('(\d*)_/; #The Regexp pattern as per your requirements.
puts(pat.match(my_text)[1]);
Output:
83085640

Where can I find the documentation for define (see snippet below) in Ruby?
define :brew do
package #name,
:ensure => :present,
:provider => :homebrew,
:require => "Vcsrepo[/usr/local]"
end
I am not sure whether it is a Ruby keyword actually.
Wouldn't it make sense to tell people where you saw the snippet, to provide context?
It's likely you're looking at a Puppet script:
http://docs.puppetlabs.com/puppet/3/reference/index.html
The place to find the definition of define, then, is in the Puppet source.
It's not a ruby keyword, you can find a list of ruby keyword in http://ruby-doc.org/docs/keywords/1.9/

I have:
def is_valid_cool_string(str)
...
end
And I want to write something like is_valid_cool_string("Foobar") at the bottom of the file to do this. Is there like a main method or something like that?
Thanks!
You don't need anything to make this work. :)
Don't forget to print the result if the method returns something.
puts is_valid_cool_string("Foobar")
or something like
puts "Is valid: #{is_valid_cool_string("Foobar").inspect}"

<script type="text/javascript">
jwplayer('mediaspace').setup({

Hi I need the xpath query to get the "file : http://www.vidok.co/cfs-ak-snc6/2012-12-17457.mp4" from this script.
Thank's
Here's an approach:
"substring-before(substring-after(/script, ''file': '),
''image'')"
And if you really want the "file : " at the beginning, use concat('file : ', theaboveexpression).
But if you ask me, XPath is not the best tool for this job.
Better to use something like regular expressions to parse the Javascript.

I want to create a method which will give me the user's full name.
the user has a first_name and a sur_name attribute.
I am trying to do something like
def fullname
"#{self.first_name} #{self.sure_name}"
end
but it gives me a method missing error when I try to do #user.fullname
am I missing something?
You have a typo: your method calls sure name (with an "e"), and you want sur name (without an "e").

I need some guidance on how to do the following..
Let say I have this string below
s= {"name":testName,"age":20}
how should I construct my regular expression in ruby, such that I am able to get "testName"
Thank you in advance
The data you have is a JSON string. You should not parse it with a regular expression, but parse it into an object and then access the name property.
I am not a Ruby dev, but you can do so if you have the JSON gem.
I agree with Jason about using JSON, but if you really can't...
1.9.3p194 > s= '{"name":testName,"age":20}'
=> "{\"name\":testName,\"age\":20}"
1.9.3p194 > s =~ /"name":(.*?)(,"|})/
=> 1
1.9.3p194 > puts $1
testName
Note that this is evil and wrong and will probably hurt little kittens... use JSON to save the kittens.
