Installation

Published to both hex.pm and the private flickswitch hex repository. Public consumers add:

def deps do
  [
    {:exdateutil, "~> 1.1"}
  ]
end

Flickswitch projects take it from the private repo instead. Register the repository once per machine — reads need the auth token, ask SRE (this is the read token, not the publish token):

curl -sS https://hex.flickswitch.cloud/repos/flickswitch/public_key -o /tmp/flickswitch_hex_public_key.pem
mix hex.repo add flickswitch https://hex.flickswitch.cloud/repos/flickswitch \
  --public-key /tmp/flickswitch_hex_public_key.pem --auth-key <read-token>

def deps do
  [
    {:exdateutil, "~> 1.1", repo: "flickswitch"}
  ]
end

Docs are on HexDocs. The private repo serves packages only, no docs.

Releasing

Push a v<version> tag matching @version in mix.exs. The release workflow builds the precompiled NIFs for all six targets, attaches them to the GitHub release, rebuilds the checksum manifest from those artifacts, then publishes to hex.pm and to the private repo.
