=== Namespace === | |||
All code should be in the octave namespace (this is an ongoing project, we | |||
are still moving existing classes into namespaces but all new classes | |||
should go somewhere into octave::). There is 1 extra level for namespaces | |||
inside octave to be used with care, we don't want too many namespaces. | |||
Ask before creating a new namespace. | |||
* Do not indent namespace; | |||
* Define namespace on the .cc files; | |||
* Do not use "using X" directives; | |||
* Do not declare anything on the std namespace; | |||
