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

New features

Windows Support

Opam 2.2 comes with native Windows compatibility. You can now use opam from your preferred Windows terminal! We rely on the Cygwin UNIX-like environment for Windows as a compatibility layer, but it is possible for packages to generate native executables.

For more details, see blog post entry.

Support MSYS2 on Windows for depexts [#5348 @jonahbeckford #5433 @rjbou]
Don't require cc on Windows [#5541 @dra27]
Generate init and variables for Windows [#5541 @dra27]
When defined, add Cygwin binary path to build environment [#5543 @rjbou]
Depexts support Cygwin on Windows [#5542 @rjbou] [#5544 @rjbou]
On Windows, ask for pre-existent Cygwin installation, check it, and configure opam with it [#5544 @dra27 @rjbou]

Recursive Pin

Recursive pinning allows to have opam lookup for opam files into subdirectories. It provides 2 new options --recursive and --subpath <path> that permit, respectively, to lookup recursively in directories, and to focus on a given directory. They can be combined.

For more details, see blog post entry.

Reactivate subpath and recursive pinning --recursive and --subpath [#4876 @rjbou] [#5219 @rjbou]

Tree

opam tree show packages and their dependencies on a tree view. It can also display a reverse-dependency tree (through opam why, which is an alias to opam tree --rev-deps`), which can be useful to examine how dependency versions get constrained.

For more details, see blog post entry.

Add tree subcommand to display a dependency tree of currently installed packages [#5171 @cannorin - fix #3775]
Add why subcommand to examine how the versions of currently installed packages get constrained (alias to tree --rev-deps) [#5171 @cannorin - fix #3775]
tree subcommand now supports --json option [#5303 @cannorin - fix #5298]

Recommended development tools

There is now a way for a project maintainer to share their project developments tools: the with-dev-setup dependency flag. It is used in the same way as with-doc and with-test.

For more details, see blog post entry.

Add --dev-setup option to install recommended development tools from opam file (as with-test/with-doc), and its environment variable OPAMWITHDEVSETUP, and for post-messages [#5016 #5160 #5214 @rjbou - fix #4959]
Opam file: Add with-dev-setup variable for recommended tools [#5016 #5214 @rjbou]

Software Heritage binding

Opam now integrates a fallback to Software Heritage archive retrieval, based on SWHID. If an SWHID url is present in an opam file, the fallback can be activated.

For more details, see blog post entry.

Add Software Heritage fallback when downloading archive source, triggered when all urls and cache fails, with confirmation [#4859 @rjbou @zapashcanon]
Add swhid url handling in url field [#4859 @rjbou @zapashcanon]

opam - 2.1.0~rc2

Published by AltGr over 3 years ago

This is the second release candidate of opam 2.1.0.
Binaries and full archive are signed by opam dev team (fingerprint 92C5 26AE 50DF 3947 0EB2 911B ED4C F1CA 67CB AA92).

It contains 2 fixes in addition to the original release candidate:

Fix compilation of the z3 optional solver backend (#4717)

Release Candidate Overview

Since beta4, the release candidates further extend the CLI versioning feature and introduce support to allow tools compiled with older versions of the opam libraries to read opam roots which have been upgraded by a newer version of the opam client. Naturally, it includes many bug fixes since the last beta.

New features

CLI versioning: new "default" CLI where deprecated options are accepted (in the major version) if the CLI hasn't been explicitly selected with --cli (#4503)
CLI versioning now applies to environment variables and flag enums
Environment variables are now only read by the client when the configuration is loaded, rather than the library (#4606)
Deprecated build-doc, build-test, make flags (#4581)
Add --no, --confirm-level and OPAMCONFIRMLEVEL for automatic answering of prompts (#4582)
Add a --with-0install-solver option to the configure script to enable the 'builtin-0install' solver (#4646)
The options --root and --switch are now reflected in environment variables when building packages so that calls to opam during build access the correct root and switch (#4668)
Introduce a default-invariant config field, restore the 2.0 semantics for default-compiler (#4577)
opam roots upgraded to a newer version of opam are read in best effort mode by an older opam library (#4636)
Improve installation times by only tracking files listed in .install instead of the whole switch prefix when there are no install: instructions (and no preinstall commands) (#4422)
Opam file: Rename hidden-version to avoid-version (#4527)
Include doc field in opam-show (#4565)

Bug fixes

Don't refer to base packages in messages any more (#4572)
Give the correct command when demonstrating switch creation (#4673)

Don't look for lock files for pin depends (#4505)

opam - 2.1.0~rc

Published by AltGr over 3 years ago

This is a release candidate of opam 2.1.0.
Binaries and full archive are signed by opam dev team (fingerprint 92C5 26AE 50DF 3947 0EB2 911B ED4C F1CA 67CB AA92).

Overview

This release candidate further extends the CLI versioning feature and introduces support to allow tools compiled with older versions of the opam libraries to read opam roots which have been upgraded by a newer version of the opam client. Naturally, it includes many bug fixes since the last beta.

New features

CLI versioning: new "default" CLI where deprecated options are accepted (in the major version) if the CLI hasn't been explicitly selected with --cli (#4503)
CLI versioning now applies to environment variables and flag enums
Environment variables are now only read by the client when the configuration is loaded, rather than the library (#4606)
Deprecated build-doc, build-test, make flags (#4581)
Add --no, --confirm-level and OPAMCONFIRMLEVEL for automatic answering of prompts (#4582)
Add a --with-0install-solver option to the configure script to enable the 'builtin-0install' solver (#4646)
The options --root and --switch are now reflected in environment variables when building packages so that calls to opam during build access the correct root and switch (#4668)
Introduce a default-invariant config field, restore the 2.0 semantics for default-compiler (#4577)
opam roots upgraded to a newer version of opam are read in best effort mode by an older opam library (#4636)
Improve installation times by only tracking files listed in .install instead of the whole switch prefix when there are no install: instructions (and no preinstall commands) (#4422)
Opam file: Rename hidden-version to avoid-version (#4527)
Include doc field in opam-show (#4565)

Bug fixes

CLI versioning

Scrub OPAM* environment variables added since 2.0 from package builds to prevent warnings when a package calls opam (#4660)
Add opam config deprecated subcommands in the default cli (#4503)
Clearer messages about using --cli and OPAMCLI (#4655)

Plugin handling

Ensure the symlink for a plugin is maintained on each invocation and reset the plugin symlinks when the root is upgraded (#4619)
Expect plugins to end in .exe on Windows (#4709)

Switch & install

Don't patch file twice (#4529)
With --deps-only, set dependencies as root packages (#4502)
Keep global lock only if root format upgrade is performed (#4597)
Send the 'opam root layout update' message to stderr (#4692)
Fix default invariant with no system compiler (#4640)
Correct the message when more than one depext is missing (#4678)
Only display one conflict message when they are all owing to identical missing depexts (#4678)
Don't exclude base packages from rebuilds (made some sense in opam 2.0 with base packages but doesn't make sense with 2.1 switch invariants) (#4569)
Don't refer to base packages in messages any more (#4572)
Give the correct command when demonstrating switch creation (#4673)

Don't look for lock files for pin depends (#4505)
Fetch sources when pinning an already pinned package with a different url when using working directory (#4484)
Don't ask for confirmation for pinning base packages (similarly makes no sense with 2.1 switch invariants) (#4571)
Fix version pin source retrieving: mustn't error if archive opam file is malformed (#4580)
opam list --silent renamed to --check (#4323)

Opam variables

Fix sys-ocaml-cc, sys-ocaml-arch and sys-ocaml-libc when no system compiler installed (#4706)
Fix Not_found (config file) in config report (#4570)
Config report: Print variables of installed compilers and their (installed) dependencies (#4570)
