Setting up a Windows IDE in Eclipse

(with thanks to Pete Jemian, APS)

NB: Eclipse requires Java SE!

• This section is optional, if you want to use an IDE like ​Eclipse and not a text editor like ​Vim then carry on reading.

• Read the instruction on how I did it below or follow this simple ​guide by Pete Jemian.

• This section will explain how to set up SasView in Eclipse because it's the most commonly used open-source IDE. Get a copy and install it on your computer. ​http://www.eclipse.org/downloads/

• Now you will need to download the PyDev plugin for Eclipse in order to get the python to work. ​https://sourceforge.net/projects/pydev/files/

• Once these are installed load up Eclipse. It will ask for a workspace directory to store the project files in, you can choose anywhere.

• Make sure that you are in PyDev mode. You can see this in the top right corner of Eclipse.

• Setup a new project. File ‣ New ‣ PyDev Project. Name it something sensible like SasView? Project. Leave all options as default but make sure the option "Create 'src' folder and add it to the PYTHONPATH" is selected.

• Then, you have to go to File ‣ Import, and choose the File System option:

• Select the directory where your files are located and the input Folder, and click finish.

• Add the directory where the external packages are stored to the PyDev settings. Window ‣ Preferences ‣ PyDev ‣ Interpreter-Python ‣ Libraries ‣ New Folder.

• If you still have errors with wxPython then remove your interpreter and add it again. After a restart of Eclipse the errors should have disappeared.

• Finally right click on the project, properties and then change the PyDev PYTHONPATH so that it contains the build directory. This is needed for debugging purposes.

• Open sansview.py and hit the run button.
