opam-state 2.0~alpha5 · OCaml Package

Synchronisation and downloading of repositories and package sources

val repositories : 
  OpamStateTypes.rw OpamStateTypes.repos_state ->
  OpamTypes.repository list ->
  OpamStateTypes.rw OpamStateTypes.repos_state

Update the given repositories from their upstream, and returns the updated state. This also saves the updated cached state, and the updated repository config (it may be changed by e.g. redirects)

val dev_packages : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.package_set ->
  OpamStateTypes.rw OpamStateTypes.switch_state * OpamTypes.package_set

update_dev_packages t checks for upstream changes for packages first in the switch cache and then in the global cache. Return the packages whose contents have changed upstream.

Side-effect: update the reinstall file, adding installed changed packages to the current switch to-reinstall set.

val dev_package : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.package ->
  ((OpamStateTypes.rw OpamStateTypes.switch_state ->
   OpamStateTypes.rw OpamStateTypes.switch_state)
   * bool)
    OpamProcess.job

Updates a single dev or pinned package from its upstream; returns true if changed, false otherwise, and a switch_state update function, applying possible changes in packages metadata

val pinned_packages : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.name_set ->
  OpamStateTypes.rw OpamStateTypes.switch_state * OpamTypes.package_set

A subset of update_dev_packages that only takes packages names and only works on pinned packages. Also updates the reinstall file of the current switch

val pinned_package : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  ?version:OpamTypes.version ->
  OpamTypes.name ->
  ((OpamStateTypes.rw OpamStateTypes.switch_state ->
   OpamStateTypes.rw OpamStateTypes.switch_state)
   * bool)
    OpamProcess.job

Updates a dev pinned package from its upstream; returns true if changed, false otherwise, and a switch_state update function that applies possible changes in packages metadata. Updates the on-disk overlay

val download_upstream : 
  'a OpamStateTypes.switch_state ->
  OpamTypes.package ->
  OpamTypes.dirname ->
  OpamTypes.generic_file OpamTypes.download option OpamProcess.job

Download or synchronise the upstream source for the given package into the given directory. For non-VC remotes, verifies the checksum if any

val fetch_dev_package : 
  OpamFile.URL.t ->
  OpamTypes.dirname ->
  OpamTypes.package ->
  OpamTypes.generic_file OpamTypes.download OpamProcess.job

Low-level function to retrieve the package source into its local cache
