IronPython API

Details

• A detailed description of the API is located in the client's help folder (%client_folder%\help).

• If you have trouble opening the file, see the hints below.

• Another version can be found here: Iron_python_API_C39521.chm

How to

• To access the documentation, download the file mentioned above.

• Right-click on the file and select properties.

• Click on Unblock and then on Apply.

Please note

• We only support the methods listed in the appropriate IronPythonAPI.

• Every Client function that is used via IronPython but which is not part of the official API may not work anymore after a Client update.

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 that in C#, Visual Basic, and Visual C++ it is "String" but in Python it is "str"

• Due to 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 explicitly use the attribute getitem instead of [] or please make sure that indexers are used correctly.

Reload modules on local client without client restart

Information

• In order to apply code changes without a client restart being necessary, 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

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]()
