IronPython 1.1 is now available for
SharpDevelop 22.214.171.12448. The IronPython addin is an early alpha
release and is not an official part of SharpDevelop 2.2.1 so it is
available as a separate download at the end of this post.
The addin will not work with SharpDevelop 3.0 nor IronPython
- Code folding
- Syntax highlighting
- File and project templates for Console and Windows Forms
- Code completion (limited)
- Windows Forms designer
- C# and VB.NET code conversion to Python
Please note that code completion, the forms designer and code
conversion all need a lot more work.
Creating a Windows Application
Open up the new project dialog by selecting New then
Solution from the File menu. Selecting the Python
category will show two project templates. One will create a Windows
console application and the other will create a Windows Forms
Once you have created a new project you will then need to add a
reference to the IronPython assembly. Open the Projects
window by selecting Projects from the View menu. In
the Projects window, right click the project and select
Add Reference. Select the .NET Assembly Browser tab
and click the Browse button. Then browse to IronPython.dll.
The addin includes this file so can either extract it from there or
if you installed it from the sdaddin file then you should be able
to find the IronPython.dll in the folder:
C:\Documents and Settings\[YourUserName]\Application
To build the application select Build Solution from the
The built executables cannot be run with the debugger so instead
select Run without debugger from the Debug menu. If
you are running a windows app and nothing seems to happen then open
a command line window and run it from there. This way you should
see any errors reported from the IronPython runtime.
There are a few file templates which can be added to the project
as shown below.
Designing Windows Forms
The Windows Forms designer is still in its early stages so
please be warned that it may break the form's code or worse.
Most of the Windows Forms controls work with the designer but
things like adding columns to a list view will generate code that
does not compile.
The designer can be opened in the usual way by opening the form
in the text editor and selecting the Design tab at the bottom of
the text editor.
Once open in the designer you can add controls to the form in
the usual way from the Tools window. In the screenshot below a
label, text box and a button have been added.
Click the Source tab to view the generated code in the
Code folding allows you to collapse regions of a class.
Code completion is very limited currently. If you type a space
after an import statement then you will get a list of namespaces
Code completion for classes is one area which has the most
limited support. If you open Program.py you can get code completion
for static classes such as System.Console but it does not work
To convert VB.NET or C# to Python open the file you want to
convert and then select Convert code to Python from the
The code conversion is limited to classes so it will not convert
an arbitary piece of code that is not inside a class. A C# class
being converted to Python is shown below.
The code conversion is still at an early stage of development so
it will fail on complicated classes.
Classes in the open solution will be displayed in the Class
browser (Select Classes from the View menu).
From there you can double click a class or method and the text
editor will display the corresponding code.
Standalone Python Files
The addin has support for standalone Python files. If you open a
file with a .py file extension then a Python menu will appear.
From this menu you can run ipy.exe and have it execute the file.
Any output from the Python script will be shown in the Output
By default the ipy.exe run is the one that ships with the addin.
You can choose another IronPython console by select Options
from the Tools menu. Selecting the Python option
allows you to choose another IronPython console.
Installing the IronPython AddIn
- Rename the IronPythonAddIn-0.2.1.zip file to
In the Open File Dialog browse to the
file and click the
- Click the Close button.
- Restart SharpDevelop.
Since SharpDevelop 126.96.36.19948 is the last release in the 2.x
branch the next release of the IronPython addin will be for
SharpDevelop 3.0 and it will support IronPython 2.0.
