Ubuntu Development Setup

Tested on (2019-Oct-25)

~~Ubuntu 18.04.3~~ (Python 3.7+ is required.)
Ubuntu 19.04

Note: Not using a fork in this example! Make sure to create a fork if you want to contribute some changes!

sudo apt install git python3-virtualenv libgirepository1.0-dev libcairo2-dev python3.7-dev
git clone https://dev.gajim.org/gajim/python-nbxmpp.git
git clone https://dev.gajim.org/gajim/gajim.git
git clone https://dev.gajim.org/gajim/gajim-plugins.git

# Apparently running virtualenv for Python 3 is weird: 
python3 -m virtualenv -p python3.7 venv
source venv/bin/activate
pip install -e python-nbxmpp
pip install pygobject css-parser pyopenssl ipython python-axolotl

python-axolotl is required for the omemo plugin to work

mkdir config
ln -s ../gajim-plugins config/plugins.testprofile  # Yes, this looks weird but that's how it works. ;)
cd gajim
./launch.py -p testprofile -c ../config -s -l gajim=DEBUG

Now make yourself a test account and you're good to go!

If you want an IPython console you can also run the last command again with an additional -i.

./launch.py -p testprofile -c ../config -s -l gajim=DEBUG -i

When you enter a command there you will get output in the terminal which is a bit confusing but it's usable.
