= HowTo use the RwdCalc Program


rwdcalc is a web brower interface to arithmetic commands


3. use a calculator


The GUI interface used is RubyWebDialogs 


Start the program by typing 
ruby init.rb

Then point your web browser to:
http://localhost:7705/




== Calculator

add or multiply 2 numbers together

subtract or divide

see a running tape


 
== Documents
 
  when you click on a document name, the document should pop up in a 
  browser window, or in another browser tab.

To exit, press the x inside the browser window.




Requirements:
RubyWebDialogs - I am using 0.0.11 2004-3-9
 This package you downloaded rwddemo should have a runtime version of 
 the needed rubywebdialog files

Ruby I am using version 1.8.2

I have tested this under Linux-Debian kernel 2.6.9

Operation:
The code files reside in the code directory and are combined before 
the main Class is loaded

The rwd files in gui are combined before the gui is activated

Installing:

untar the file
tar zxvf rwdshell-x.y.tar.gz
then cd to the directory
cd rwdshell-x.y
then start the init.rb program file
ruby init.rb
Trouble shooting:

If the program is not working, try looking at the ev subdirectory. That is where
the runtime of rubywebdialogs are.

for long term installation, I would suggest putting most files in a lib directory
like /usr/lib/rwdshell
then make a writable directory the local directory for command files to be written
like ~/rwdshell


Closing the browser doesn't terminate the application. You have to use the application's close-button  And terminating the application doesn't terminate the application when running in network mode. You just log out.

Don't use the back-button of the browser! Strange and unpredictable things may and will happen!

RubyWebDialogs is a platform independent graphical user interface for Ruby applications. It generates HTML and serves it with an internal HTTP server, so you can use your favorite web browser as the front end for your Ruby application. All this means, that it can be used on almost every platform, like Ruby itself. http://www.erikveen.dds.nl/rubywebdialogs/
