Warning messages for TCL, Ruby, Perl support in WrapITK

• • 9d9215c DOC: Shorten the message for TCL support in WrapITK
  • d9bc5a2 ENH: TCL support in WrapITK is marked as unstable
• pushed to gerrit here

Included in ITK v4.alpha

MetadataDictionary access from target languages

• modify itkMetaDataDictionary.h to add those methods:

 + MetaDataObjectBase::Pointer & Get(const std::string &) const;
 + void Set(const std::string &, MetaDataObjectBase * );
 + std::vector< std::string > Keys() const;

• add a specific language customization for python, to make the metadata accessible in a more usual way.

 + a __setitem__() method to add/modify a metadata in the dictionary
 + a __len__() method to return the number of metadata in the dictionary
 + a __getitem__() method - this one should take care to down cast the object to its real type
 + a __str__() method to print the content of the dictionary
 + a __iter__() method to return every elements in the dictionary one by one

Tcl SmartPointers

Look at how SmartPointers are replaced by swig proxy objects in python and java and explore the possibility to do the same in Tcl to decrease the build time of WrapITK.

not ready for beta.

Fix Installation

• They are currenly in /usr/local/lib/cmake/ITK-4.0/WrapITK -- that's not good
• Option ${CMAKE_INSTALL_PREFIX}/lib/ITK-4.0/ accepted in the ITK developers list
  • Put all wrapITK libraries here along with libraries of other packages. We won't require versioned names.
• Gerrit-Push

Ready for Beta

Remove the USE_WRAP_ITK option

• Enabling a language in cmake should be enough.

Not for Beta.

Build swig as an external project

• As it's done for gccxml.
• If you look in the gerrit abandoned patch, you will find a change proposed by Kent Williams which can be partially reused.
• ONGOING

Ready for Beta

Integrate WrapITK in the ITK modularization

• First step - Restructure the WrapITK Libraries directory to look it similar to the Modules directory here
• ONGOING

Ready for Beta

Pending Tasks

Ready for Alpha

• [GL-01] - [100%] - migrating to WrapITK 0.3
• [GL-06] - [100%] - Default wrapped types [...],
• [GL-08] - [33%] - Wrapping coverage,
  • metadata dictionary
  • macro moved to swig

ready for Beta

• [GL-05] - [75%] - Redefine the WrapITK libraries, (follow modular, no need monolithic anymore)
• [GL-14] - [--%] - Automatic type selection in Python,

Ready for Meeting MICCAI

• [GL-03] - [--%] - Port the SWIG interface gen. to C++,
• [GL-09] - [--%] - Binary distribution,
  • one full build, sub package ( python, java, tcl, dev (cmake, swig interfaces, ...) ) independently installable, possible to distribute
  • generation with CPack

Ready for Dec - end of contract

• [GL-02] - [--%] - Add support for C#, => ashish
• [GL-04] - [--%] - Add support for Python 3, => gaetan
• [GL-07] – [--%] - Extend support to more types, (unsigned long for win 64 ) => Alex, replace all unsigned long by SizeValueType (done in ITK but not WrapITK)
• [GL-10] – [--%] - language specific array conversion, (NOTE: simple itk did it for C# and java, we have it in python) => gaetan (python almost done, java and C# is being worked out in simpleITK, wait for them)
• [GL-12] - [--%] - Automatic Inline documentation, done in python, prototype existing in Java. all is done in python, so we need to port it to C++ (see GL-03)
• [GL-13] - [--%] - Target language inheritance, swig expertise, all languages => ashish
• [GL-17] – [--%] - Documentation (user guide)
• [GL-18] – [--%] - Documentation (dev. Guide)
