[Gems-users] Question about adding a command to Ruby

["wmyhome"<wmyhome@xxxxxxxxx>]

Title: Mail

Hi all,

 

    I'd like to add a command "getparm" to Ruby in order to get a certain parameter's value.

    I want it to be used like "ruby0.getparam g_NUMBER_PROCESSORS" and it return the value "2" to me.
  
    I did these things as the document told:

    1. Decide name of command, arguments, etc.
    2. Add an entry for your command to module/commands.py.
    3. Add a RUBY_COMMAND([COMMAND_NAME]) macro in module/ruby.c.
    4. Update module/ruby.c's ruby_session_set() function to check for the new command.
    5. Add a declaration of [FUNCTION_NAME] to simics/commands.h.
    6. Implement [FUNCTION_NAME] in simics/commands.C.

   

    Then I recompiled Ruby successful. But when I used it in a python file like this:

    run("ruby0.getparam g_NUMBER_PROCESSORS")

   

    There is something wrong. It says:

    sim_core.SimExc_IllegalValue: attribute getparam in object ruby0: illegal value
    Failed executing Python file: PyRun_File() failed

   

    Can someone tell me how I should solve this problem? Thanks a lot!
