These are common procedures which developers might want to do.

Moving a message between packages

• First make clean in the old_package (to clear autogenerated files)
• Move the message

svn mv old_package/msg/name.msg new_package/msg/name.msg

• Find all usages of the message:

rosmsg users old_package/name

• For each usage change the namespace to reflect the new_package
  • In Python this will entail:
    • changing the package name on import
    • changing instances of the package name throughout
  • In C++ this will entail:
    • Fixing #include
    • changing namespace of each declaration usage.
    • also check for using namespace old_package.
    • The search only detects #includes you may need to find source files that include the headers found.
• Before committing make sure you got all instances

roscd old_package && make buildtest && roscd new_package && make buildtest
