Overview

A more complete overview of opam 2.1.0~beta4 is on the platform blog.

CLI Versioning

--cli was added in the first beta, but is now used throughout the CLI (see #4385). When invoking opam from a script or program, we recommend using --cli=2.1. If you need to be compatible with 2.0, you can set the environment variable OPAMCLI to 2.0 (this is done automatically by opam when building packages).

As with changes in the Dune language, changes to opam's CLI are now immediate - for example, --unlock-base is now unavailable without selecting the opam 2.0 CLI (you must use --update-invariant). Like Dune, opam tries to be helpful and the errors include pointers to the new syntax.

Other new features

• opam now exits with code 31 if all failures were during fetch operations (#4214)
• opam install now has a --download-only flag (#4036), allowing opam's caches to be primed
• opam init now advises the correct shell-specific command for eval $(opam env) (#4427)
• post-install hooks are now allowed to modify or remove installed files (#4388)
• New package variable opamfile-loc with the location of the installed package opam file (#4402)
• opam update now has --depexts flag (#4355), allowing the system package manager to update too
• depext support NetBSD and DragonFlyBSD added (#4396)
• The format-preserving opam file printer has been overhauled (#3993, #4298 and #4302)
• pins are now fetched in parallel (#4315)
• os-family=ubuntu is now treated as os-family=debian (#4441)
• opam lint now checks that strings in filtered package formulae are booleans or variables (#4439)

Changelog (possibly scripts breaking changes are prefixed with ✘):

New features

Recursive pin

Opam now handles lookup for opam files on subdirectories with recursive, subpath based, and subpath recursive pin: --recursive and --subpath PATH options. On recursive mode, opam goes through subdirectories to find opam files & pin them to their subdirectories. On subpath based mode, opam goes to the given subdirectory to find opam file & pin it to this subdirectory.

• Recursive & subpath based pin [#3499 @rjbou @hngrgr - fix #3174 #3477] {2.1.0-alpha}

Switch Invariant

Define switch base packages as a switch invariant, a generic dependency formula instead of an immutable specific package/version.

• Define switch invariants rather than "base packages" [#3894 @AltGr] {2.1.0-alpha}

• Don't warn on switch creation with 'ocaml' as invariant [#4108 @AltGr] {2.1.0-alpha}

• Better error handling on switch creation [#4121 @AltGr] {2.1.0-alpha}

Lock

opam-lock was during a long time an opam plugin, and it is now integrated into opam. Option --locked permits to lock an opam package, according the current switch. It produces a locked file (by default <pkgname>.opam.locked, can be specified with --lock-suffix) that contains the original opam file with its depends: field all package are set to their exact version available in the current switch.

• Integrate lock plugin [#3746 @rjbou - fix #3734 #3769 #3694] {2.1.0-alpha}

• Check consistency with opam file when reading lock file to suggest regeneration message [#3680 @rjbou - fix #3654] {2.0.2}

Options configuration

Replace switch and global variables settings opam config set options, by opam var and opam option to generalize them to all modifiable options and variables:

• opam var|option: list modifiable options and their values

• opam var|option foo: display foo value, available for all

• opam var|option foo(=|-=|+=)bar: update foo value

• opam var|option foo=: remove/revert foo value

By default, acts on switch scope. It can be specified with --global or --switch sw.

It deprecates opam config (set|unset|set-global-unset-global) commands.

• Add configuration modifications as opam config subcommands [#3992 @rjbou] {2.1.0-alpha}

• opam var and opam option outside of opam config [#4116 @rjbou - fix #4119] {2.1.0-alpha}

• Enable option var optim switch load [#4138 @rjbou] {2.1.0-alpha}

Depext

opam-depext is also a long time opam plugin, used to show / install external dependencies of opam packages. It is now fully integrated in the opam workflow:

• check of installed package dependencies

• on install, check that required dependencies are present, show / propose to install if not

Global configuration option depext, depext-verify, depext-cannot-install, depext-run-installs, and depext-bypasspermit to configure depext use and interactions. CLI options--assume-depextsand--no-depexts` can also be used for a single command.

• Integrate depext plugin [#3975 @rjbou @AltGr - fix #3790 #1519 #2426 #3692] {2.1.0-alpha}

• Enable command/output display only from verbose level 3 [#4141 @rjbou] {2.1.0-alpha}

New options

Install

• opam install --check <pkg> checks that <pkg> dependencies are already installed in the switch. It reports missing ones and exits with 1, 0 otherwise. It is used on a check only purpose, additionally to --deps-only. [#3854 @rjbou - fix #3823] {2.1.0-alpha}

• --ignore-conflicts to use with --deps-only in case it is needed to install dependencies without taking conflicts into account. [#3853 @rjbou - fix #3846] {2.1.0-alpha}

Show

• opam show --just-file <file> shows information of a given file, without loading the switch state. It can be combined with other options, as field filter --field. It deprecates --file option. [#3729 @rjbou - fix #3721] {2.1.0-alpha}

• opam show --all-versions <pkg> displays information of all versions of the given package. It can be used in combination of field filter. [#3867 @rjbou - fix #2980] {2.1.0-alpha}

• opam show --sort <pkg> display on stdout a sorted opam file: all fields are alphabetically sorted. [#3866 @rjbou - fix ocaml/opam2web#173] {2.1.0-alpha}

• Better error handling. [#4118 @rjbou - fix #3875] {2.1.0-alpha}

Lint

• opam lint --check-upstream enables lint checks on archive urls. This option lead to download archives to check their checksum. [#3758 @rjbou] {2.0.5}

List

• --silent to not write in the output, exit with return code 0 if the list is not empty, 1 otherwise. [#3533 @rjbou - fix #3525] {2.0.1}

Env

• opam env --check permit to indicates if an opam environment is synchronized: returns 0 if up-to-date, 1 otherwise. [#4074 @rjbou - fix #3725] {2.1.0-alpha}

Switch export

• --freeze option record VCS commit hash when a VCS url is specified. [#4055 @hannesm] {2.1.0-alpha}

• With --full option, include extra-files in switch export, on import create an overlay directory with the file contents. [#4040 @hannesm] {2.1.0-alpha}

Enhancements, updates, and fixes

Repository Management

• Optimize repository loading: we store the repository contents as .tar.gz files in ~/.opam/repo instead. Rather than resorting to a complex in-memory structure, we just untar them to /tmp when they need to be read, and re-tar them after modification (opam update, or format upgrade only). Then we let the OS disk cache do the job: in normal operation, the tree never needs to be flushed to disk, and loading the .tar.gz is orders of magnitude faster than loading the individual files. [#3752 @AltGr - fix l#3721] {2.1.0-alpha}

Fixes

• Remove mismatching extra-files: sort list before comparing them. [#3744 @rjbou] {2.0.4}

• Handle failure or interruption of tar during opam update. [#3861 @AltGr] {2.1.0-alpha}

• Fallback in case repository archive doesn't exist. [#4008 @rjbou] {2.1.0-alpha}

• In case repository archive is corrupted, delete it and ask to launch an update. [#4075 @rjbou - fix #4053] {2.1.0-alpha}

• When adding a repository, an error is displayed in case of mismatching urls, now both urls are displayed. [#4086 @rjbou - fix #4085] {2.1.0-alpha}

Update

• Handle url backend change to VCS of a package from repository. [#4007 @rjbou - fix #3991] {2.1.0-alpha}

Switch & install

• Allow local compiler switch creation. [#3720 @rjbou - fix #3713] {2.1.0-alpha}

This is the release of opam 2.0.0.

See the Upgrade Guide for an overview of changes.

This is the final release of opam 2.0.0.

Since there is a repository format change involved from our last stable release 1.2.0, we are leaving a few weeks for things to settle before officially switching the official package repository to 2.0.0 format. This release remains tagged as rc4 in the meantime.

You are encouraged to switch as soon as you see fit:

• there is already a 2.0.0 branch in the official repository, that is automatically used by opam 2, and automatically updated.
• opam 2.0.0 can read 1.2.0 repositories and package definition files transparently.
• on the other hand, once the switch is made, new packages will appear only on opam 2.0.0. Backports to the 1.2.0 repository will be limited.

See the Upgrade Guide to get started with opam 2.0 and see what is new.

• A bunch of fixes over rc2
• A new opam switch link SWITCH [DIR] command to bind a directory to a switch
• A new opam install --assume-built option to install through opam packages that have been built by hand

This new release candidate for opam 2.0.0 fixes many small issues with the previous one, is much faster in many areas, and brings sandboxing of package commands (enabled by default) on macOS and Linux.

opam init now also provides the option to setup a hook in your shell such that the environment is synchronised at every prompt, avoiding the need for ever running eval $(opam env). This is particularly useful when working with local switches.

Release candidate for 2.0.0
