Consider your software broken if

Consider your software broken if:

  • You're the only one to understand how it works
  • You can't remember what a function does just by reading its name
  • You're not using a version control system
  • You're not using continuous integration
  • You're not continuously monitoring the quality of your code
  • You have little or no unit tests
  • You have little or no integration tests
  • You don't use an issue tracker

Build cross-plaform graphical installers for Python software

Distributing Python software to non-technical users is too hard. We need to make it simpler.

I'm imagining a tool based on conda.

Ideally I'd like to have something like this:

  • I write an environment.yml file with the conda/pip dependencies for my software
  • I write an installer.yml file that describes my installer: package name, paths to logo/images, icon shortcuts for binaries, etc.
  • I type build-installer and a few files are created:
  • mypackage.sh: for Unix systems
