Installation & Setup

Download & install the Eclipse SDK (eg, eclipse-SDK-4.3.2-win32) to a folder of your choice Eclipse name their versions:


Do not install a version of Eclipse earlier than 4.3.1 Note that there are some subtle variations in the menu trees between versions! Most of this document was originally written whilst using Ganymede.

Setting Proxy

If your internet access is normally via a proxy server, locate and edit your C:\Users\userid\AppData?\Roaming\Subversion\servers file and add under the [global] section:

http-proxy-host = site_proxy_server_address
http-proxy-port = site_proxy_server_port

To see if you use a proxy server, and to get it’s address, open Internet Explorer, then go Tools → Internet Options → Connections → LAN Settings and look to see if you are using an automatic configuration script. If so it will probably be configured to use port 8080. If in doubt, contact your IT Support.

Installing PyDev?

Start Eclipse and open: File → Switch Workspace → Other… → Select a workspace (the default is drive:\path\Eclipse_workspace)

Window → Open Perspective → Other → PyDev?

If PyDev? is not listed as a perspective it will be necessary to install it:

Help → Install New Software… and in the Work With: drop-down select the PyDev? Update Site. Let the list of available software refresh.

Check the box next to PyDev? and click Next. The plug-in will install.

If this doesn’t work:

Download the PyDev? certificate from and install it (in Windows, just right-click and select Install certificate)

Now get PyDev? from If you have Java 7 installed, you must install PyDev? 3.4.1 or later. Extract the zip file to the Eclipse dropins folder and re-start Eclipse

Installing Subversive

For SVN access it is necessary for Eclipse to have the Subversive plug-in installed. Earlier versions of Eclipse (e.g. 4.3.1) seemingly incorporated an SVN plug-in in the default distribution. Later versions (e.g. Kepler) do not!

To install Subversive:

  • (Help → Install New Software… and in the Work With drop-down select the site for the Eclipse

release you are using. Let the list of available software refresh.

  • Scroll down the list of available software and locate Subversive SVN Team Provider Sources (or similar). Check the box next to it and click Next. The plug-in will install.
  • Restart Eclipse.
  • Window → Preferences → Team → SVN → SVN Connector
  • Check the drop-down. If present, select JavaHL (for Windows x86). If this is not present it will be necessary to install the connector.

To install the Subversive Connector:

  • Help → Install New Software
  • Let the list of available software refresh.
  • Scroll down the list of available software and locate a JavaHL Binaries plug-in appropriate to your OS. Check the box next to it and click Next. The plug-in will install.
  • Restart Eclipse.

Checking out Sasview Trunk

File → Import → SVN → Checkout Projects from SVN → Next

IF no_SVN_repository_shown: Check ‘Create a new repository location’ → Next → Enter a URL for a SVN repository → Next

If Eclipse fails to download the trunk, try repeating the import process but this time using an existing repository (see below).

ELSE: Check ‘Use existing repository location’ → Select a SVN repository from the list shown → Next

The SasView? SVN repository is hosted by SourceForge? at:

For commit access aspiring developers need (read-only checkout is public):

  1. to be registered with Source Forge, and
  2. authorised by Paul Butler

Eclipse will attempt to download the trunk. In the process it may be necessary to enter your SourceForge? login details several times (because you are required to authenticate at each level of the repository) so check the ‘Save details’ box to speed up the authentication process.

Enter a Workspace Location

This can be any name you like, but will be the name given to your local trunk, and the name of the folder it is stored in; ie, drive:\path\Eclipse_workspace\workspace_location

If you want you can also give this location a custom label. Do not change any of the other default settings on this dialog box!

Click OK

Preparing to Build SasView?


Installing Python

The official version of Python for building SasView? is 2.7

Install NumPy?, SciPy?, and the additional Python site packages for building SasView?

NB: if you are using a Win64 version of Python ensure you also download and install a Win64 version of wxPython compatible with your Python 2.x installation!

Install the other additional packages for building SasView?

Install MINGW

In Windows Explorer: Navigate to drive:\path\Python2x\lib\site-packages and delete any existing sasview .egg file

Back in Eclipse: Window → Preferences → General → Editors → Text Editors

Check ‘Insert spaces for tabs’

Check ‘Show print margin’ and set the ‘Print margin column’ to 80

Check ‘Show line numbers’

Click OK

Window → Preferences → PyDev? → Interpreter – Python

If no Python interpreter is shown, click ‘New…’, enter a name for your Python installation and ‘Browse…’ to its python.exe file

Click OK

In the PyDev? Package Explorer pane:

Navigate to the sansview folder within the trunk

Right-click on  Run As  Python Run

If this fails with an error message in the console pane it means that there is no existing SasView? build – which is what you want! If, on the other hand, SasView? starts up, search for a sasview .egg file!

Then repeat this test.

Locate in the top level of the trunk

Right-click on  Properties  Run/Debug? Settings

IF no_launch_configuration shown: New → Enter a name for the launch configuration

Select the ‘Main’ tab → Under ‘Project’, browse to the name of your trunk

Select the ‘Arguments’ tab → Type ‘install’ (without the quotes) in the box marked ‘Program arguments’

Click OK

Building SasView? the First Time

Right-click on → Run As → Run Configurations…

Or highlight your_trunk_project and then choose Run → Run As → Python Run

SasView? should build from your local trunk. If the build fails it will most likely be because a Python package has not installed, in which case install it manually (eg, using easy_install)

If you get an error about msvcr90.dll or msvcr90d.dll not being found, copy these from the Visual C++ Redistributable installation (if present) or from a reputable website and put in your MinGW/bin folder.

Re-building SasView? after Development

Navigate to the within the trunk

Right-click on → Run As → Python Run

SasView? should build!

The locally-built version of SasView? should appear in drive:\path\Eclipse_workspace\workspace_location\dist as something similar to sasview-3.0.0_r0-py2.7-win32.egg

Running SasView? from Eclipse

Navigate to the within the trunk

Right-click on → Run As → Python Run

SasView? should start up!

NB: This is running SasView? from compiling and building the Python/C/C++, it is not installing SasView?

NB: If you run SasView? at this point it may stop an Installer application from building, so if you want an Installer application, create that first (see below)!

Creating a SasView? Installer Package

NB: You would not normally need to do this because that is the function of the Build Server! Navigate to the sansview folder within the trunk

Right-click on  Run As  Python Run

This should create a file SasView?.exe in the sansview\dist folder of the trunk

Double-click on installer.iss to bring up the Inno Setup Compiler

Click the green ‘play’ button to build a SasView? installer

This should create a file setupSasView.exe in the sansview\Output folder of the trunk

Running Unit Tests

Locate an appropriate unit test in your_trunk_project\module\test

Right-click on the file → Run As → Python unit-test

NB: unit tests operate on the last built version of SasView?, so if you have modified any modules or unit tests you must re-build SasView? first!

The unit test your_trunk_project\test\ executes all the unit tests

NB: you must have previously installed unittest_xml_reporting (eg, easy_install unittest_xml_reporting)

Also see the section on ‘Checking the Build Server Tests’ below

Committing Code Changes to the SVN Server

NB: run appropriate unit tests first!

Save your changes to

Right-click on → Team → Update (just in case someone has done something to the same file!)

Right-click on → Team → Commit

Add a comment to describe your changes

To See/Compare? Code Changes


Right-click on  Compare with  Revision… / Local History…


Go to Source Forge


Projects  SasView?  Code

NB: if you haven’t been coding for a while, right-click on the top level of the trunk and do Team → Update

To Tidy Up the Trunk

Right-click on the top level of the trunk

Team → Cleanup

Checking the Build Server Tests

The Build Server automatically runs the unit tests as part of the build process, and reports the success/failure

See, for example:

If a build has failed unit tests the ‘ball’ will be red

Click on the date/time string next to the ball to get a view of what changes were committed to that build and what tests failed

Click on a failed test link to see more detail about why a test failed


Long-term code development projects, or modifications carrying a significant risk of breaking the code, should not be committed to the trunk, but conducted in a branch of the trunk instead Note that a branch is not simply a sub-folder of trunk The top-level of the SasView? code repository contains:

the web pages
the code in the current development build
the code in the current official release build
copies of trunk being used for special development projects

Only when branches are debugged, working and tested should they be merged back into the trunk.

NB: developers using branches should be aware that their branch copy of trunk will naturally fall behind the current trunk and should therefore periodically update their branch copy of trunk

To create a branch in Eclipse:

  • Right-click on your_trunk_project → Team → Branch/Tag?
  • Modify the URL shown by adding /branches/name_of_branch
  • Click Next
  • Select the HEAD Revision
  • Click OK

To check if a branch has been created/exists:

  • Switch to SVN view (top right corner of the Eclipse screen)

To work with a different branch:

  • In PyDev? view, right-click on the top-level of the current trunk → Team → Switch to another
  • Branch/Tag/Revision?
  • Modify the URL shown to point to the appropriate branch
  • Click OK
