Including dot files in the hex package archive

There is a flag you can pass to the mix archive.build command to include dot (“hidden”) files in your archive: --include-dot-files. The problem is, hex.build command doesn’t support that flag.

Recently, I learned that when running mix hex.build, the command uses aliases defined in the project’s mix.exs file. That allowed me to create an alias that includes the flag.

defp aliases do
  [
    "archive.build": "archive.build --include-dot-files",
  ]
end
