meta_package_manager.managers.roswell module¶

class meta_package_manager.managers.roswell.Roswell[source]¶

Bases: PackageManager

Roswell, a Common Lisp implementation installer and launcher.

Important

A roswell package is a Lisp implementation, not a Lisp library. ros install``accepts both an implementation and a Quicklisp system, but``ros list installed answers for implementations alone: a system installed with ros install cl-ppcre never appears there.

Initialize cli_errors list.

operation_notes: ClassVar = {'remove': "The `ros delete` command reports success and breaks roswell's own runtime, so `mpm` will not drive it.", 'upgrade': 'The `ros update` command upgrades Quicklisp systems, never the implementations the listing reports.'}¶

Per-operation hints rendered in the Notes column of the manager page’s Operations table.

Keyed by the Operations member name, each value is a single short sentence explaining why the manager lacks the operation, or what makes its implementation partial: the pointer a reader needs to judge whether the gap is one they could help close. Each sentence starts with a capital and closes with a period, and starts on a word rather than a code span, so the cell reads standalone beside its row. A blank cell stays silent: a manager documenting nothing documents no gap.

The full rationale never lives here: it belongs in a comment beside the implementing method (or beside this declaration, for an operation with no method to hang it on), so the sentence on the page stays a hint and the code keeps the story. The class docstring follows the same split: it keeps only what a user needs to run the tool day to day, never how mpm wraps it.

Validated by test_operation_notes, which also checks every key matches a real operation: a key outside the enum’s vocabulary would never reach a page.

name: str = 'Roswell'¶

Return package manager’s common name.

Default value is based on class name.

homepage_url: str | None = 'https://roswell.github.io/'¶

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

Left unset when the home page is the project’s repository, which repository_url names on its own, and when it is the project’s manual, which documentation_url names. Never inherited, like the other links.

documentation_url: str | None = 'https://github.com/roswell/roswell/wiki'¶

Entry point of the project’s own documentation, or None when it has none.

The manual, the documentation site, or the man page of the CLI mpm drives: whichever page a user reads to learn the commands this manager wraps. Listed between homepage_url and repository_url in the links of the manager’s page, so a reader reaching for the tool’s reference finds it in the box of facts rather than in the prose below it.

Left unset where a link would state a fact twice or invent one: a tool documenting itself in its repository alone, whose README repository_url already reaches. A page about the ecosystem rather than the tool does not qualify either.

Where a project’s only site is its manual, that address belongs here and homepage_url stays unset: the slot names what the page is, and a reader reaching for the reference looks under the documentation link.

Never inherited, like every other link: the AUR helpers extending pacman each document themselves.

repository_url: str | None = 'https://github.com/roswell/roswell'¶

Repository holding the project’s code, or None when it has no public one.

Linked from the manager’s documentation page. Also what the weekly metrics sample reads: docs/docs_update.py writes it into the [tool.repomatic.metrics] subjects of pyproject.toml when its forge answers the sampler, through a mirror for a forge that does not.

Never inherited, for the same reason as wikipedia_url: the AUR helpers extending pacman each live in a repository of their own.

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.

keywords: tuple[str, ...] = ('common lisp', 'quicklisp')¶

Well-known names for this manager that its id does not already carry.

Merged into the PyPI keywords of pyproject.toml by update_keywords() of docs/docs_update.py, alongside every manager ID and the globally curated KEYWORDS_EXTRAS. Declare an alias here rather than in that tuple whenever it names this manager: an alias living beside the class it describes cannot outlive it, where a central entry silently rots once the manager is renamed or dropped.

Reserve KEYWORDS_EXTRAS for terms belonging to no manager in particular, like cyclonedx or package manager. Documentation-only: no CLI output reads it.

Each keyword also becomes a content rule of the issue labeller, so its precision bar applies here: see generate_content_rules(). A subclass inherits the terms of its parent without claiming them, since test_manager_keywords_have_one_owner reads what a class declares itself.

platforms: frozenset[Platform] | Group | Platform | Iterable[Platform | Group] = frozenset({Platform(id='aix', name='IBM AIX'), Platform(id='almalinux', name='AlmaLinux'), Platform(id='alpine', name='Alpine Linux'), Platform(id='altlinux', name='ALT Linux'), Platform(id='amzn', name='Amazon Linux'), Platform(id='android', name='Android'), Platform(id='arch', name='Arch Linux'), Platform(id='buildroot', name='Buildroot'), Platform(id='cachyos', name='CachyOS'), Platform(id='centos', name='CentOS'), Platform(id='chromeos', name='ChromeOS'), Platform(id='clearlinux', name='Clear Linux OS'), Platform(id='cloudlinux', name='CloudLinux OS'), Platform(id='crux', name='CRUX'), Platform(id='cygwin', name='Cygwin'), Platform(id='debian', name='Debian'), Platform(id='dragonfly_bsd', name='DragonFly BSD'), Platform(id='endeavouros', name='EndeavourOS'), Platform(id='exherbo', name='Exherbo Linux'), Platform(id='fedora', name='Fedora'), Platform(id='freebsd', name='FreeBSD'), Platform(id='generic_linux', name='Generic Linux'), Platform(id='gentoo', name='Gentoo Linux'), Platform(id='guix', name='Guix System'), Platform(id='haiku', name='Haiku'), Platform(id='hurd', name='GNU/Hurd'), Platform(id='ibm_powerkvm', name='IBM PowerKVM'), Platform(id='illumos', name='illumos'), Platform(id='kali', name='Kali Linux'), Platform(id='kvmibm', name='KVM for IBM z Systems'), Platform(id='linuxmint', name='Linux Mint'), Platform(id='macos', name='macOS'), Platform(id='mageia', name='Mageia'), Platform(id='mandriva', name='Mandriva Linux'), Platform(id='manjaro', name='Manjaro Linux'), Platform(id='midnightbsd', name='MidnightBSD'), Platform(id='netbsd', name='NetBSD'), Platform(id='nixos', name='NixOS'), Platform(id='nobara', name='Nobara'), Platform(id='nutyx', name='NuTyX'), Platform(id='openbsd', name='OpenBSD'), Platform(id='opensuse', name='openSUSE'), Platform(id='openwrt', name='OpenWrt'), Platform(id='oracle', name='Oracle Linux'), Platform(id='os400', name='IBM i'), Platform(id='parallels', name='Parallels'), Platform(id='pidora', name='Pidora'), Platform(id='pikaos', name='PikaOS'), Platform(id='raspbian', name='Raspbian'), Platform(id='rhel', name='RedHat Enterprise Linux'), Platform(id='rocky', name='Rocky Linux'), Platform(id='scientific', name='Scientific Linux'), Platform(id='slackware', name='Slackware'), Platform(id='sles', name='SUSE Linux Enterprise Server'), Platform(id='slitaz', name='SliTaz GNU/Linux'), Platform(id='solaris', name='Solaris'), Platform(id='solus', name='Solus'), Platform(id='sourcemage', name='Source Mage GNU/Linux'), Platform(id='sunos', name='SunOS'), Platform(id='tuxedo', name='Tuxedo OS'), Platform(id='ubuntu', name='Ubuntu'), Platform(id='ultramarine', name='Ultramarine'), Platform(id='void', name='Void Linux'), Platform(id='windows', name='Windows'), Platform(id='wsl1', name='Windows Subsystem for Linux v1'), Platform(id='wsl2', name='Windows Subsystem for Linux v2'), Platform(id='xenserver', name='XenServer')})¶

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.

requirement: str | None = '>=22.12.14.113'¶

The oldest release whose listing this parser was checked against.

lisp/list-installed.lisp is byte-identical from there through the current 26.02.116, the *error-output* header included, so the shape below is not a property of the release that happened to be driven.

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

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).

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

The trailing (NO-GIT-REVISION) is left out of the capture: it names the build, not the version, and a release tarball carries it in place of a commit.

$ ros --version
roswell 26.02.116(NO-GIT-REVISION)
id: str = 'roswell'¶

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.

version_from_stderr: bool = True¶

Both ros --version and ros version leave <stdout> empty and write to <stderr>, measured at 0 and 35 bytes respectively.

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.

wikipedia_url: str | None = None¶

English Wikipedia article about the project, or None when it has none.

Listed last in the links of the manager’s documentation page. The article covers the project that home page names, or is a redirect Wikipedia keeps under the project’s name, landing on the part of a broader article that describes it: Cargo_(software) opens the Cargo section of the Rust article. An article that merely mentions the project does not count, nor does one about a related subject: lazy is a Neovim plugin manager, and the Neovim article is not about it.

Never inherited: the metaclass resets it to None on any class not declaring its own. A subclass often wraps a distinct project, like the six AUR helpers extending pacman, and would otherwise present pacman’s article as its own. Documentation-only, like homepage_url.

property installed: Iterator[Package]¶

Fetch installed Lisp implementations.

Only the rows reach <stdout>; roswell prints its headings to <stderr>, so the payload arrives with no furniture to skip.

An implementation is listed once per installed version, so the rows are reduced to the newest version of each.

Caution

An empty listing is not proof of an empty machine. Roswell answers 0 with nothing on <stdout> and its diagnosis on <stderr> alone once it can no longer resolve the implementation it runs on, which a ros delete of the wrong version is enough to cause. must_succeed cannot catch that, keying on the exit code, so the two streams are compared instead and a silent failure is raised rather than reported as zero packages.

$ ros list installed
sbcl-bin/2.6.8
install(package_id, version=None)[source]¶

Install one Lisp implementation.

A version is appended to the implementation with a slash, the same impl/version spelling installed() reports.

$ ros install sbcl-bin
$ ros install sbcl-bin/2.6.8
Return type:

str
