Switch a codebase to the development state.
rpp_to_dev()
The development state of the codebase
may include type checking and more but cannot
be submitted to CRAN and impacts performance
of runtime code.
Also, currently this state is not meant to be committed to version control;
this may change in further versions.
Ensure you switch back to
the production version with rpp_to_prod()
after development work is done.
