Flora Namespaces

In Flora, packages are categorised in a namespace to mark their provenance. They start with a @ and allow us to refer to packages unambiguously or mark their importance.

@hackage Packages​

This is where most third-party packages live, which you will find on Hackage.

@cardano Packages​

Flora also indexes the Cardano Haskell Packages (CHaP), an index of packages by the Cardano project. These packages live under the @cardano namespace.

To use them in your own project, insert the following configuration in your cabal.project file:

repository cardano
  url: https://input-output-hk.github.io/cardano-haskell-packages
  secure: True
  root-keys:
    3e0cce471cf09815f930210f7827266fd09045445d65923e6d0238a6cd15126f

and run cabal update.

@horizon Packages​

Additionally, Flora also indexes the packages from the Horizon project. These packages live under the @horizon namespace.

To use them in your own project, insert the following configuration in your cabal.project file:

repository horizon
  url: https://packages.horizon-haskell.net/
  secure: True
  root-keys:
    272e995c7a74de109518100e1422193fe5e5971e52c92b98147c9355b47d7bb6

and run cabal update.

@mlabs Packages​

Additionally, Flora also indexes the packages from the MLabs Cardano ecosystem. These packages live under the @mlabs namespace.
