Noob: http script to google finance

Ruby
#1

Hello everybody, I’m learning Ruby, coming from Java and Python.

I thought a good first project would be to duplicate a script I’ve
previously done in Python, which takes a list of stock symbols and
does an http GET from google finance to pull the current stock price.

I started out by looking at the net.http library. However the
documentation isn’t super descriptive as far as usage:

http://www.ruby-doc.org/stdlib-1.9.3/libdoc/net/http/rdoc/Net/HTTP/Get.html

This was a bit surprising to me coming from Python where the docs are
pretty good. Bascially, I am expecting to do a get and ruby returns a
string of the page html.

Is there another place documentation wise I should be looking? Or do I
just grab the interpreter and start experimenting? That’s fine also,
but if there is a better documentation source I thought I’d ask.

Thanks!

Hi,

You should generally look for the documentation of the top level classes
(in this case Net::HTTP or Net). That’s were you’ll find explanations,
usage examples etc.

http://www.ruby-doc.org/stdlib-1.9.3/libdoc/net/http/rdoc/Net/HTTP.html

As a simple example:

require ‘net/http’

include the Net module so you don’t always have to prepend “Net”

include Net

response = HTTP.get ‘www.ruby-forum.com’, ‘/’
print response

I just created a new gem to provide a command line interface for
searches on rubygems.org.

gem install gemqs

gemqs term1 term2
…search results

Hope it’s useful.

It seems to work like a charm. The one nitpick I have so far is that
my terminal is set to 160 columns but it truncates the output lines to
170 characters; so there are 7 characters plus ‘…’ sitting all alone
on a line sometimes.

For some reason I don’t see your announcement on ruby-forum.com …

Ahh yes… that’s why I didn’t see it on the forum.

Sorry about that, my mistake.
