Re: [Lcdproc-ruby-newcomers] [Lcdproc] LCDproc Digest, Vol 7, Issue 12

Hi Sascha,

Assuming you have Ruby installed, CD into the LCDProc-Ruby directory
where you extracted the download and type:

ruby script/console.rb

This will open an interactive console that you can use to play with
the library. You can look at some of the examples to see how they
work, but basically, you create a client, attach a screen and attach
widgets.

c = Client.new(:host => "localhost", :name => "test");
s = Screen.new("test_screen")
w = Widget.new( :string )

c.attach(s)
s.add_widget(w)


This should create a basic screen that has the word "Hello" at the top
left (it defaults to hello, you can pass any string you want). You can
debug a bit by typing

c.messages

and see basically a log of everything you have done.


You may also be interested in running the tests:

CD into the LCDProc-Ruby directory and type:

rake -T

to see the tests, or

rake test:basic

to run the basic tests. Just go to http://www.rubygems.org/ and
download the latest version for your OS. Then run

gem install rake

Also, the online documentation is below. It's not complete, but it should
get you started.

http://lcdproc-ruby.sourceforge.net/index.html

Let me know if you need anything else! I'll be glad to help.

P.S. I'm forwarding this to the LCDProc-Ruby list in case anyone else
has similar questions.
