meta_package_manager.managers.zef module

class meta_package_manager.managers.zef.Zef[source]

Bases: PackageManager

Zef, the module manager of the Raku language.

A package is a Raku distribution, identified by the bare name its identity string opens with. Raku names are colon-separated (JSON::Fast) and the identity appends its own colon-prefixed fields to them (JSON::Fast:ver<0.20>:auth<zef:timo>), so every pattern here matches the name lazily up to the literal :ver< rather than splitting on colons.

Note

Two distributions may share a name and differ only by the auth field, and several versions of one may be installed side by side. mpm keys a package on its id alone, so both listings are reduced here to one entry per name, keeping the highest version. That reduction is what makes this a class rather than a bundled definition.

Note

Search compounds the same problem rather than avoiding it: it answers with a pipe-delimited table carrying one row per (distribution, version) pair, so a single module comes back once per release it has ever published.

Note

No outdated: zef reports no staleness of its own. upgrade covers both the bulk and the single-package cases natively, so neither is synthesized.

Documentation: zef README.

Initialize cli_errors list.

name: str = 'Zef'

Return package manager’s common name.

Default value is based on class name.

homepage_url: str | None = 'https://github.com/ugexe/zef'

Home page of the project, only used in documentation for reference.

List of platforms supported by the manager.

Allows for a mishmash of platforms and groups of platforms. Will be normalized into a frozenset of Platform instances at instantiation.

version_regexes: tuple[str, ...] = ('^(?P<version>\\d+\\.\\d+\\.\\d+)',)

Search the bare version zef prints on its own.

Return type:

str

upgrade_all_cli()[source]

Generate the CLI to upgrade all packages.

$ zef upgrade
Return type:

tuple[str, ...]

cli_names: tuple[str, ...] = ('zef',)

List of CLI names the package manager is known as.

This list of recognized CLI names is ordered by priority. That way we can influence the search of the right binary.

..hint::

This was helpful in the case of the Python transition from 2.x to 3.x, where multiple versions of the same executable were named python or python3.

By default, this property’s value is derived from the manager’s ID (see the MetaPackageManager.__init__ method above).

id: str = 'zef'

Package manager’s ID.

Derived by defaults from the lower-cased class name in which underscores _ are replaced by dashes -.

This ID must be unique among all package manager definitions and lower-case, as they’re used as feature flags for the mpm CLI.

upgrade_one_cli(package_id, version=None)[source]

Generate the CLI to upgrade one package.

$ zef upgrade JSON::Fast
Return type:

tuple[str, ...]

virtual: bool = False

Should we expose the package manager to the user?

Virtual package manager are just skeleton classes used to factorize code among managers of the same family.

remove(package_id)[source]

Remove one package.

$ zef uninstall JSON::Fast::Hyper
===> Uninstalled from inst#/opt/homebrew/Cellar/rakudo-star/2026.07/share/perl6/site

sync()[source]
