There are two things we should do here.

  • add a --version option to each mlpack executable (in cli.hpp or similar)
  • add a C++ function that will return a string containing the version of mlpack

There's a bit more, though; a subversion post-commit hook will need to be added to update the definition of the version string, so that it will look something like 'r15886' instead of just 'trunk' if trunk is being used.

--version option and C++ function mlpack::util::GetVersion() added in r16090. A post-commit hook is not the right way to update that, though; a better idea is to use CMake+svn at build time to see if the source directory is a repository, and if so, update what GetVersion() returns.

Fixed as of r16105. Maybe we should use svnversion instead of svn info though.

Since we switched from svn to git (github) the GetVersion() function doesn't work anymore.

The following files are used to get the version that need to be updated:

  • mlpack/CMakeLists.txt
  • mlpack/src/mlpack/core/util/version.cpp
  • mlpack/CMake/CreateSVNVersionHeader.cmake

For now, Ryan implemented a temporary workaround to fix the problem in 61a1064 which creates the version string 1.x.x.
