Activity Launching
The key functions for launching activities are
These functions are called in the order listed from
which are, in turn, called from
These six functions (and the relatively simple helpers they call) exhaust the functionality provided by rainbow-0.7.0.
Developing Rainbow
I develop Rainbow in four basic modes:
- From a live git clone, when developing new features.
cp setup.py.in setup.py sed -i -e 's/@VERSION@/1/' setup.py python setup.py develop
- By packaging snapshots of a git clone to try out packaging changes.
make snapshot
- With locally-built or scratch-built packages, when I'm getting ready to tag a release.
make release
- With an official release, built with Fedora's Koji build system from sources archived in Fedora CVS.
