meta_package_manager.managers.zinit module

meta_package_manager.managers.zinit.zinit_source_path()

Locate the zinit.zsh file every invocation sources.

Falls back to the current installer’s location when none of the candidates exists, so the built command stays well-formed and simply fails to source, which is what makes the version probe double as Zinit’s presence check.

Return type:

Bases: PackageManager

Zinit is a flexible and fast Zsh plugin manager.

Zinit installs Zsh plugins, snippets and completions from GitHub and other forges, cloning each into $ZINIT[PLUGINS_DIR]. Packages are identified by the user/repo slug Zinit both reports and accepts, which is the id mpm keys them on. A plugin the user renamed through the id-as ice reports under that alias instead, and feeds back into every operation just the same.

Caution

zinit is a shell function, not a standalone binary, so every invocation is wrapped in zsh -c 'source <zinit.zsh> && zinit <args>'. Zsh is therefore the manager’s CLI, and Zinit’s own presence is established by the version probe: a host with Zsh but no Zinit fails to source and reports no version, which leaves the manager unavailable.

Caution

Zinit.installed() is the one operation that cannot use that wrapper. Zinit tracks plugins in shell state populated by the zinit load calls of the user’s .zshrc, so a freshly sourced non-interactive shell knows of none. That query therefore runs zsh --interactive, paying a full shell startup to inventory what the user’s Zsh actually loads. Plugins deferred with the wait ice (Zinit’s turbo mode) load asynchronously after the prompt would have been drawn, so a non-interactive run may miss them.

Note

No outdated: Zinit’s only “what would change” command is zinit status --all, which unconditionally runs .zinit-self-update first, pulling and recompiling Zinit itself. A query that mutates the manager is not a query, so mpm auto-skips the operation and upgrade --all still works.

Note

No search: Zinit resolves plugins straight from forge URLs and indexes no registry to search.

homepage_url: str | None = 'https://github.com/zdharma-continuum/zinit'

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

logo: str | None = 'zsh'

Slug of the brand mark standing for this manager in the documentation.

Names an SVG vendored under docs/assets/managers/, whose provenance and license are recorded in docs/assets/managers/logos.yaml. Inlined at the top of the manager’s page by meta_package_manager._docs; a manager leaving it unset keeps the page’s default package glyph.

Several managers legitimately share one slug, either because they wrap the same upstream (brew and cask) or because the tool has no mark of its own and its ecosystem’s stands in (apt under Debian’s swirl, cargo under Rust’s gear). Documentation-only, like homepage_url: no CLI output reads it.

requirement: str | None = '>=3.10.0'

First release of the zdharma-continuum fork whose confirmation prompt, and thus the --yes flag Zinit.remove() depends on, behaves.

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

Zsh is the binary mpm actually executes.

Zinit itself is a shell function defined by a zinit.zsh file that is sourced, never executed, so it cannot serve as the manager’s CLI: mpm requires an executable, and that file ships non-executable. Keying the manager on Zsh instead makes the version probe the presence check, since sourcing an absent zinit.zsh yields no version and leaves the manager unavailable.

extra_env: ClassVar = {'SHELL_SESSIONS_DISABLE': '1'}

Keep macOS’ Zsh session bookkeeping from writing a session file on every query.

version_cli_options: tuple[str, ...] = ('version',)

CLI options used to produce the version of the package manager.

The raw output produced by the package manager CLI will be parsed with the version_regexes below to extract the version number.

version_regexes: tuple[str, ...] = ('zinit\\s+v(?P<version>\\S+)',)

Zinit reports the git describe of its own checkout, so a clone sitting past a tag reports a 3.15.0-5-gb1946ac flavored version.

$ zinit version
zinit v3.15.0 (darwin25.4.0_arm64)

id: str = 'zinit'

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.

name: str = 'Zinit'

Return package manager’s common name.

Default value is based on class name.

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.

build_cli(*args, **kwargs)

Wrap all CLI invocations in the Zsh shell Zinit needs.

Three subcommands need a shell of their own shape, so the wrapper is chosen from the subcommand rather than being uniform.

plugins reads the plugin registry out of shell state that the zinit load calls of the user’s .zshrc populate, so it runs zsh --interactive and lets that file do the sourcing. Sourcing zinit.zsh again on top would reset the registry and report nothing.

load is prefixed with the cloneonly ice, which stops Zinit right after the clone. Installing a plugin otherwise sources it, running third-party shell code inside the process mpm drives.

version is guarded by a readability test that exits successfully when zinit.zsh is absent. Zsh is the default shell on macOS and near ubiquitous elsewhere, so an unguarded probe would turn every host that merely has Zsh into a manager reporting errors. A zinit.zsh that is present but broken still fails loudly.

Note

The **kwargs accepted by the base class (auto_pre_args, sudo, etc.) are accepted but ignored because every invocation goes through the zsh -c wrapper and Zinit never requires elevated privileges.

Return type:

tuple[str, ...]

property installed: Iterator[Package]

Fetch installed packages.

Zinit reports no version alongside a plugin, so packages are yielded bare: pinning a plugin to a revision is an ice modifier of the user’s own zinit load call, not state Zinit surfaces in this listing.

$ zsh --interactive -c 'zinit plugins'
==> 3 Plugins

 1 L ~zinit/zinit.git

 2 L zdharma-continuum/fast-syntax-highlighting

 3 U zsh-users/zsh-completions


Loaded: L | Unloaded: U

install(package_id, version=None)

Install one package.

Zinit conflates installing a plugin with sourcing it, so Zinit.build_cli() sets the cloneonly ice ahead of this call.

$ zinit load zdharma-continuum/null

Return type:

str

upgrade_all_cli()

Generates the CLI to upgrade all packages.

Note

Zinit self-updates before updating anything else, so this also pulls and recompiles Zinit itself.

$ zinit update --all

Return type:

tuple[str, ...]

upgrade_one_cli(package_id, version=None)

Generates the CLI to upgrade one package.

$ zinit update zdharma-continuum/null

Return type:

tuple[str, ...]

remove(package_id)

Remove one package.

$ zinit delete --yes zdharma-continuum/null

Return type:

str
