opam-client 2.1.0~beta4 · OCaml Package

Functions handling the "opam pin" subcommand

val version_pin : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.name ->
  OpamTypes.version ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Pins a package to the given version, and writes to disk. Returns the updated state. The main difference with source_pin is that a definition overlay is not created. Therefore, the package must exist already.

exception Aborted

exception Nothing_to_do

val source_pin : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.name ->
  ?version:OpamTypes.version ->
  ?edit:bool ->
  ?opam:OpamFile.OPAM.t ->
  ?quiet:bool ->
  ?force:bool ->
  ?ignore_extra_pins:bool ->
  ?subpath:string ->
  OpamTypes.url option ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Sets the package as pinned to the given target. A package definition is looked for in the package source and current metadata (in this order), unless specified using ~opam.

If edit, or if no package definition is found, this opens an editor (with a template if no definition is available).

If force, don't abort even if the source can't be fetched from target

May raise Aborted or Nothing_to_do.

val handle_pin_depends : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.package ->
  OpamFile.OPAM.t ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Interactively handles the pin-depends in an opam file

val fetch_all_pins : 
  'a OpamStateTypes.switch_state ->
  (string * OpamTypes.url * string option) list ->
  (OpamTypes.url * string option) list

Fetch in parallel jobs a list of pins name, url, subpath, and return the successful ones. Ask for confirmation to continue if a fetching fails.

val edit : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  ?version:OpamTypes.version ->
  OpamTypes.name ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Let the user edit a pinned package's opam file. If given, the version is put into the template in advance. Writes and returns the updated switch state.

val unpin : 
  OpamStateTypes.rw OpamStateTypes.switch_state ->
  OpamTypes.name list ->
  OpamStateTypes.rw OpamStateTypes.switch_state

Unpin packages

val unpin_one : 
  'a OpamStateTypes.switch_state ->
  OpamTypes.package ->
  'a OpamStateTypes.switch_state

Pure function that reverts a single package pinning

val list : 'a OpamStateTypes.switch_state -> short:bool -> unit

List the pinned packages to the user.

val scan_sep : char

Scan pinning separator, used for printing and parsing by scna and parse_pins.

val scan : 
  normalise:bool ->
  recurse:bool ->
  ?subpath:string ->
  OpamTypes.url ->
  unit

Scan for available packages to pin, and display it on stdout. If normalise is true, displays it's normalised format `name.versionscan_sepcurlscan_sepsubpath`.

val looks_like_normalised : string list -> bool

Detect if a string is a normalised format of scan.

val parse_pins : 
  string list ->
  (OpamTypes.name * OpamTypes.version option * OpamTypes.url * string option)
    list

Parse the normalised form of scan, and returns pinning informations.

val read_opam_file_for_pinning : 
  ?quiet:bool ->
  OpamTypes.name ->
  OpamFile.OPAM.t OpamFile.t ->
  OpamTypes.url ->
  OpamFile.OPAM.t option

Lints the given opam file, prints warnings or errors accordingly (unless quiet), upgrades it to current format, adds references to files below the 'files/' subdir (unless the file is directly below the specified, local url), and returns it

val default_version : 
  'a OpamStateTypes.switch_state ->
  OpamTypes.name ->
  OpamTypes.version

The default version for pinning a package: depends on the state, what is installed and available, and defaults to ~dev.
