1.5. Creating a new cube from scratch#

Let’s start by creating the cube environment in which we will develop

cd ~/myproject
# use cubicweb-ctl to generate a template for the cube
# will ask some questions, most with nice default
cubicweb-ctl newcube mycube
# makes the cube source code managed by mercurial
cd cubicweb-mycube
hg init
hg add .
hg ci

If all went well, you should see the cube you just created in the list returned by cubicweb-ctl list in the Available cubes section. If not, please refer to Environment configuration.

To reuse an existing cube, add it to the list named __depends_cubes__ which is defined in __pkginfo__.py. This variable is used for the instance packaging (dependencies handled by system utility tools such as APT) and to find used cubes when the database for the instance is created.
