Python dependencies
Pitivi has a single Python runtime dependency matplotlib
but in the
development sandbox we install quite a few Python tools.
Each Python package has its own python3-*.json
file in
build/flatpak,
generated with
flatpak-pip-generator:
$ git clone git@github.com:aleb/flatpak-builder-tools.git
Note, we use a custom flatpak-pip-generator
which downloads the compiled
Python packages. The upstream version downloads only the source packages, for
security reasons.
The hotdoc
and matplotlib
packages are quite complex, needing additional
build dependencies which have to be installed beforehand. Jan 2021 it's much
easier to install the compiled packages instead of the source packages. When
upstream makes it easier to use source packages we should switch.
Updating matplotlib
$ cd build/flatpak
$ python3 flatpak-pip-generator --runtime org.gnome.Sdk/x86_64/3.38 matplotlib
Updating the development tools
$ cd build/flatpak
$ python3 flatpak-pip-generator --runtime org.gnome.Sdk/x86_64/3.38 ipdb
$ python3 flatpak-pip-generator --runtime org.gnome.Sdk/x86_64/3.38 nose2
$ python3 flatpak-pip-generator --runtime org.gnome.Sdk/x86_64/3.38 nose setuptools_git setuptools_pep8 sphinx hotdoc
Updating the pre-commit framework
$ cd build/flatpak
$ python3 flatpak-pip-generator --runtime org.gnome.Sdk/x86_64/3.38 pre-commit
$ python3 flatpak-pip-generator --runtime org.gnome.Sdk/x86_64/3.38 pylint
Updating your local sandbox
After you update the json files, try out the build by updating your local development environment:
$ . bin/pitivi-env
(ptv-flatpak) $ ptvenv --update
If errors happen, you can inspect the SDK by launching bash
in a sandbox, for
example:
$ flatpak run --user --command=bash --devel org.gnome.Sdk/x86_64/3.38
[📦 org.gnome.Sdk ~]$ python --version
Python 3.8.6
