[Insight-users] easy way to get a file name extension

[Luis Ibanez]

Hi Darren,

Yes, you will find all these basic methods
as part of the kwsys library.

In particular you should look at the class:

Insight/Utilities/kwsys/
SystemTools.cxx
SystemTools.hxx.in

> grep Filename *.hxx*

SystemTools.hxx.in:   *               Filename Manipulation Routines
SystemTools.hxx.in:  static kwsys_stl::string GetFilenamePath(const
kwsys_stl::string&);
SystemTools.hxx.in:  static kwsys_stl::string GetFilenameName(const
kwsys_stl::string&);
SystemTools.hxx.in:  static kwsys_stl::string
GetFilenameExtension(const kwsys_stl::string&);
SystemTools.hxx.in:  static kwsys_stl::string GetFilenameLastExtension(
SystemTools.hxx.in:  static kwsys_stl::string GetFilenameWithoutExtension(
SystemTools.hxx.in:  static kwsys_stl::string GetFilenameWithoutLastExtension(
SystemTools.hxx.in:   * If 'dir' is not a directory, GetFilenamePath()
is called on 'dir' to

See examples of their use in the Insight/Code/IO directory:

For example:

   #include <itksys/SystemTools.hxx>
   itksys::SystemTools::GetFilenameName(bestBaseline);


  Regards,


         Luis
