cava-ppa

CAVA is an audio visualization tool.
This repo contains scripts to build and push cava to my PPA: https://launchpad.net/~hsheth2/+archive/ubuntu/ppa.

If you just want to install cava, execute this:

sudo add-apt-repository ppa:hsheth2/ppa
sudo apt-get update
sudo apt-get install cava

Setup

• Requires Docker.
• The secrets directory should contain two files: launchpad_id_rsa and launchpad_key.asc.

Building a new version

1. Update the cava submodule to contain the latest code.
2. Update the version number and debian revision in ppa.sh.
3. For each series (e.g. bionic, eoan, focal, groovy):
   1. Execute ./ppa.sh bionic to build the package.
   2. When the build finishes it will drop into an interactive shell. Run the dput command to upload the package to Launchpad.

Notes

• The build process is split between a docker container and a build script. The ppa.sh script manages both of them.
• The Docker container installs build and packaging dependencies and basically serves as a checkpoint to make the process faster.
• The build.sh script finishes the build process, creates and .deb file, and lets the user issue the final command to upload the PPA.
• Since the autogen.sh script from cava requires modification, we use a debian/patches directory. This directory is managed by quilt.
• TODO: figure out how to exclude the orig.tar.gz upload.
