Working with the edi Source Code
Instead of installing edi from the ppa you can also work directly with the source code.
Clone the source code:
git clone https://github.com/lueschem/edi.git
Change into the edi subfolder:
cd edi
Install various packages that are required for the development of this project:
sudo apt install -y git-buildpackage dh-make equivs && sudo mk-build-deps -i debian/control
Build the edi Debian package (just to verify that everything works):
debuild -us -uc
Make the development setup convenient by adding some environment variables (they are only valid for the current shell):
source local_setup
Verify that the source code version of edi is being used:
which edi edi version
