    Various Know-how

    Embedding IronPython code in a module

    How to
    • Select a DA in your module
    • Insert a new DF with ID 004336 and change DF-Verhalten to py
    • Close the DA and reopen it
    • Expand the DI and paste your code into IronPython Skript
    • Save and start the module
    • Add the following code at the top:
       # coding: latin-1"
    • Code that looks like this in C#:
      GetValue<T>()
    • Will look like this in IronPython:
      GetValue[T]()

    Note

    • Keep in mind for C#, Visual Basic and Visual C++ it is "String" but in Python it is "str"
    • For reason of the IronPython bug, the indexers of the generic .NET collections will not work if a first access to them was not correct (for example the indexer requires int but you put a string value). So use the attribute _getitem_ instead of [] explicitly or please be sure that indexers are used correct.

    Reload modules on local client without client restart

    Information
    • In order to apply code changes without the need of a client restart, use the following guideline.

    How to

    • Insert the following code prior to the import statement of the target module:
      sys.modules.Remove("MyModule")
    • After the statement above, place your unchanged import statement:
      from MyModule import MyModule
    • The conditions for your AddReference-statement stays the same as before - it needs to stay prior to your import statement but it can stay before or after the statement of step 1.

    Remembering data across multiple modules

    • Data can be stored somewhere in the __builtins__ dictionary
    • Unlike the server, each Client has its own IronPython interpreter, so everyone has their own copy of __builtins__

    Stop

    • Do not use __builtins__ when calling server code, for example with server_execute()

    Useful snippets

    Method Parameter Return value Comment
    df   Returns the DF the IronPython script was executed from  

    Getting the value of a DI that is in the same DA as the IronPython macro:

    df.DataArea.ChildrenDF[df.DataArea.Customizing.get_df_by_name(DF-Python-ID)].GetValue[T]()
