Hi Sascha,
I'll look into this when I go home for lunch. I haven't ever seen it steal
all of the CPU, so it might be a bit hard to debug.
Can you tell me exactly which process is using the CPU (I assume it's irb
but you never know...). Also, after you create your client, can you type
c.messages
and send me the output? Hopefully that will tell me what state the client
is in and if there were any errors when connecting. Since the method that
it died in when you hit Ctrl-C was "get_response" my guess is that it is
simply waiting for a response from the server and it did not get one. This
could mean that you aren't actually connected to the server, but I'm pretty
sure it throws some errors if there isn't a valid connection. I need to put
a timeout period in there, but regardless it shouldn't steal all of the CPU,
it should be sleeping for most of the time (therefore not processing
anything).
Just a note, you must be running LCDd in the background on the default port
for your code to work.
Also, what OS/LCDd version are you running?
Topher

Hi,
It took a long time to figure out my problem, why the console from LCDProc-Ruby
did not start. I had to create a link: "ln -s /usr/bin/irb1.8 /usr/bin/irb"
The console starts, but if I want to create a new screen my, top shows 100%
cpu load.
# ruby1.9 script/console.rb
Loading LCDProc Console Environment
>> c = Client.new(:host => "localhost", :name => "test");
?> s = Screen.new("test_screen")
^CIRB::Abort: abort then interrupt!!
from /home/Linux_Packages/lcd/LCDProc-
Ruby/lib/lcdproc/client.rb:354:in block in get_response\'
from /home/Linux_Packages/lcd/LCDProc-
Ruby/lib/lcdproc/client.rb:350:in get_response\'
from /home/Linux_Packages/lcd/LCDProc-
Ruby/lib/lcdproc/client.rb:282:in initialize\'
from (irb):1:in <main>\'
# ruby1.8 script/console.rb

>> s = Screen.new("test_screen")
=> #<LCDProc::Screen:0x00000000fb22c8 @id="test_screen", @client=nil,
@widgets=[], @key_events=[], @priority=:info,
@lcdproc_attributes={:heartbeat=>:open}>
>> c = Client.new(:host => "localhost", :name => "test");
?> s = Screen.new("test_screen")

I now have my PC working again and hopefully I can respond faster to your next
answers.

Sascha

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.
Topher

Hi,
I tried to get this running, but I don't know how. I am familar with perl, php
but I havn't read about ruby. Do you have a Howto to get this working?
