# post.nix generates a local environment for updating a Jekyll website, hosted on GitHub Pages.
# This file borrows heavily from:

# This line is to prevent a sass compile error, generated because the NixOs Docker image is built on Alpine Linux and locales are not installed by default:
  # export LANG=C.UTF-8 
  # Alternatively:
    # Add -e=LANG C.UTF-8 or --env-file=env.list to your docker run command.
      # Add LANG=C.UTF-8 to your docker env.list file
