datadata Source

A source is a location from which we can fetch, such as a HTTP URL, a GIT URL, ....

Constructors

Source
- sourceUrl :: String
  URL to fetch from.
- sourceRevision :: String
  Revision to use. For protocols where this doesn't make sense (such as HTTP), this should be the empty string.
- sourceHash :: Hash
  The expected hash of the source, if available.
- sourceCabalDir :: String
  Directory where Cabal file is found.

datadata DerivationSource

A source for a derivation. It always needs a hash and also has a protocol attached to it (url, git, svn, ...). A DerivationSource also always has it's revision fully resolved (not relative revisions like master, HEAD, etc).

Constructors

DerivationSource
- derivKind :: Maybe DerivKind
  The kind of the source. If Nothing, it is a local derivation.
- derivUrl :: String
  URL to fetch from.
- derivRevision :: String
  Revision to use. Leave empty if the fetcher doesn't support revisions.
- derivHash :: String
  The hash of the source.
- derivSubmodule :: Maybe Bool
  The fetchSubmodule setting (if any)

valuefetch

:: FetchSubmodules
whether to fetch submodules when the source is a git repository
-> (String -> MaybeT IO a)
This function is passed the output path name as an argument. It should return Nothing if the file doesn't match the expected format. This is required, because we cannot always check if a download succeeded otherwise.
-> Source
The source to fetch from.
-> IO (Maybe (DerivationSource, a))
The derivation source and the result of the processing function. Returns Nothing if the download failed.

Fetch a source, trying any of the various nix-prefetch-* scripts.

valuefetchWith

:: (Bool, DerivKind)
-> Source
-> MaybeT IO (DerivationSource, FilePath)

Like fetch, but allows to specify which script to use.
