3D Slicer now supports extensions. Extensions are available from an extension server. This allows end-users to select the extensions useful to them, without having to download the entire extension archive.

  • You can look at the examples that are currently in slicer and copy one that looks similar:

http://viewvc.slicer.org/viewcvs.cgi/trunk/Extensions/

  • Several example modules are hosted on the nitrc.org site and can be used as a template.

User documentation on extensions.

FOR DEVELOPERS

Extensions must follow the appropriate architecture and must meet minimum documentation requirements for them to be made available to end users. See Slicer3:Loadable_Modules for an example of how to make GUI and GUI-less Loadable Modules. Command Line and Scripted Modules will also work with this framework.

You can choose the version of your code that you want to make available to end users by having the Subversion repository URL in the s3ext script point to either the trunk of your code base or to a stable branch.

To enable your Command Line, Scripted, or Loadable module, add an "s3ext" script to the /Slicer3/Extensions directory of the source repository:

PythonSampleScriptedModule.s3ext:

#
# first token of each non-comment line is the keyword and the rest of the line 
# (including spaces) is the value.
# - the value can be blank
#

# scm is source code manager (i.e. svn)
scm       svn
svnpath   https://www.nitrc.org/svn/slicer3examples/trunk/Slicer3ExampleModules/Scripted/PythonSampleScriptedModule
svnusername slicerbot
svnpassword slicer

# list dependencies 
# - these should be names of other modules that have .s3ext files 
# - the dependencies will be built first
depends ScriptedModule

# homepage
homepage  http://www.slicer.org

# match category in the xml description of the module (where it shows up in Modules menu)
category  Developer Tools

# give people an idea what to expect from this code 
# - is it just a test or something you stand beind?
status    Beta

# One line description of what the module does
description This is an example of an extension module written in python

Support in Slicer 3.4

Development in the slicer3 trunk through early August 2009 has led to a version that works well and is being migrated to the 3.4 release branch for use in patch version 3.4.1. Fixes from the following files are being migrated:

  • Applications/GUI/Slicer3.{cxx,xml}
  • Base/GUI/vtkSlicerApplication.{h,cxx}
  • Base/GUI/vtkSlicerApplicationSettingsInterface.{h,cxx}
  • Base/GUI/vtkSlicerModulesWizardDialog.{h,cxx}
  • Base/GUI/vtkSlicerModulesStep.{h,cxx}
  • Base/GUI/vtkSlicerModulesConfigurationStep.{h,cxx}
  • Scripts/extend.tcl
  • launch.tcl.in

Support in Slicer 3.5

VMTK is available from http://ext.slicer.org/ext/trunk/10813-linux-x86_64
