val packages : OpamTypes.dirname -> OpamTypes.package_set

Get the list of packages

val packages_with_prefixes : 
  OpamTypes.dirname ->

Get the list of packages (and their possible prefix)

Repository backends

val update : 
  OpamTypes.repository ->
  OpamTypes.dirname ->
  [ `Changes of Patch.operation list | `No_changes ] OpamProcess.job

Update $opam/repo/$repo. Returns `No_changes if the update did not bring any changes, and `Changes of Patch.operation list representing creations, deletions, and modifications of regular files.

raises Failure
in case the update couldn't be achieved.

pull_shared_tree ?cache_dir ?cache_url labels_dirnames checksums urls Fetch an URL and put the resulting tree into the supplied directories specified in labels_dirnames. The string in labels_dirnames are text labels of this given dirname for display. urls must either point to a tree (VCS, rsync) or to a known archive type. In case of an archive, the cache_dir is used and supplied the hashes verified, then the archive uncompressed. In case of a version-controlled URL, it's checked out, or synchronised directly if local and working_dir was set. cache_urls is used to retrieve from repository caches.

  ?silent_hits:bool ->
  OpamTypes.filename ->
  OpamHash.t list ->

  unit OpamTypes.download OpamProcess.job

Same as pull_tree, but for fetching a single file.

val pull_file_to_cache : 
  string ->
  cache_dir:OpamTypes.dirname ->
  ?cache_urls:OpamTypes.url list ->
  OpamHash.t list ->
  OpamTypes.url list ->
  string OpamTypes.download OpamProcess.job

Same as pull_file, but without a destination file: just ensures the file is present in the cache and that every listed checksums are correctly linked to the archive, otherwise it adds the missing links.

val cache_file : OpamTypes.dirname -> OpamHash.t -> OpamTypes.filename

The file where the file with the given hash is stored under cache at given dirname.

val revision : 
  OpamTypes.dirname ->
  OpamTypes.url ->
  string option OpamProcess.job

Get the optional revision associated to a backend (git hash, etc.).

val current_branch : OpamTypes.url -> string option OpamProcess.job

Get the version-control branch for that url. Only applicable for local, version controlled URLs. Returns None in other cases.

val is_dirty : 
  ?subpath:OpamTypes.subpath ->
  OpamTypes.url ->
  bool OpamProcess.job

Returns true if the url points to a local, version-controlled directory that has uncommitted changes

val find_backend : OpamTypes.repository -> (module OpamRepositoryBackend.S)

Find a backend

val find_backend_by_kind : OpamUrl.backend -> (module OpamRepositoryBackend.S)

val report_fetch_result : 
  OpamTypes.package ->
  string OpamTypes.download ->
  unit OpamTypes.download

Prints user messages upon the result of a download
