scripticus 0.7.0

A package manager and registry for scripts — CLI client

Scripticus

The client for Scripticus, a package manager and registry for scripts. Publish, discover, version, and install the scripts your team shares — with proper namespacing, semver, dependency resolution, and a single bin directory on your PATH — instead of copying them around from wikis, chat, and assorted git repos.

Installing

The client requires Python 3.11+. Install it as an isolated CLI tool with pipx (recommended) or uv — either puts scripticus on your PATH without touching your project or system Python:

$ pipx install scripticus       # or: uv tool install scripticus
$ scripticus init               # creates ~/.scripticus, adds bin dir to PATH

Restart your shell (or re-source your profile) so ~/.scripticus/bin is on your PATH.

Point the client at your organisation's registries. Your org's onboarding docs will give you the exact lines to run:

$ scripticus config remote add tools https://scripticus.example.com
$ scripticus config tools --install="apt-get install -y {packages}" --escalate=sudo

Remotes are searched in the order you add them, which is also the search path for bare package names — so add them the way your organisation expects them to resolve. config remote list shows the current set.

Everyday usage

Finding packages

There are two discovery verbs, for two different questions.

search — "find me something that does X". It matches package content: name, description, and command names.

$ scripticus search backup --platform linux --lang bash
Package               Latest   Description
infra/backup-rotate   1.2.0    Rotate and prune backup sets
tools/db-backup       0.9.1    Dump and archive databases

search queries every configured remote in priority order (unlike install, which stops at the first remote that has the package) and merges the results, each shown at its latest non-yanked version. With more than one remote hit, a Remote column shows which one each result came from; --remote <name> restricts the search to a single remote. If a remote is unreachable it's reported as a warning and the rest of the results still show. The optional --platform and --language (or --lang) filters narrow results to packages that publish a matching artifact.

list — "show me what's there, by name". It enumerates package identity with a shell glob over namespace/name, dnf-style: an Installed section from your machine and an Available section from the remotes.

$ scripticus list 'infra/*'
Installed packages
Package               Version
infra/logrotate       0.4.1

Available packages
Package               Version
infra/backup-rotate   1.2.0

A glob containing / scopes by namespace (infra/*); a bare glob matches the name in any namespace (*-backup). --installed restricts to what you have installed and needs no network; --available restricts to the remotes' catalog (excluding what's already installed). --remote <name> picks which remote supplies the available list.

Installing

$ scripticus install infra/backup-rotate

With a version or semver range:

$ scripticus install infra/backup-rotate@1.2.0
$ scripticus install "infra/backup-rotate@^1.2"

If your namespace search path is configured, bare names work too:

$ scripticus install backup-rotate

Bare names are resolved against your configured namespace list in priority order — they are a client-side convenience; the installed package is always recorded under its full namespaced identity.

Before anything is written, Scripticus resolves the full dependency set and shows you a transaction summary:

Installing infra/backup-rotate 1.2.0

New packages:
  infra/backup-rotate   1.2.0   (commands: backup-rotate)
  infra/log-common      2.0.3   (dependency)

Required system tools: jq, curl        [found]
Optional system tools: fzf             [not found — some features degraded]

Shim conflicts:
  backup-rotate  currently owned by tools/old-backup 0.4.0 — will be overwritten

Proceed? [y/N]

Non-interactive use:

• -y / --yes (equivalent to --force=no-conflicts): accept the transaction, but abort entirely (nothing installed, non-zero exit) if it would overwrite an existing command shim.
• --force=all: accept everything, including shim overwrites. Every overwritten shim is reported in the output.
• --skip-tools: skip the system-tool check and installation entirely.

Required system tools missing from your PATH are installed before any package file or shim is written, by running the command your machine's [tools] configuration provides (see Configuration). If a required tool is missing and no installer is configured, the install aborts listing the tools — install them yourself, configure [tools] install, or re-run with --skip-tools. Optional tools are only reported, never installed.

Install from a local archive (no registry involved):

$ scripticus install -f ./some-local-pkg-0.0.1.tar.gz

Locally-installed packages are tracked with local provenance; update will skip them with a warning rather than trying to resolve them against a remote.

Updating and uninstalling

$ scripticus update                 # everything
$ scripticus update backup-rotate   # one package
$ scripticus uninstall backup-rotate

uninstall shows what will be removed and asks for confirmation (-y skips the prompt). If a removed command is also provided by another installed package — for example the uninstalled package had taken the shim over — you are offered a numbered list of replacements to re-point the command at, with "No replacement" as the default:

$ scripticus uninstall new-backup

Uninstalling tools/new-backup 2.0.0

Command shims to remove: backup-rotate

Proceed? [y/N]: y

Uninstalled tools/new-backup 2.0.0

'backup-rotate' is also provided by other installed packages:
  0) No replacement
  1) tools/old-backup  1.4.2
Select a replacement for 'backup-rotate' [0]: 1
'backup-rotate' now points at tools/old-backup 1.4.2

With -y no replacement is ever selected automatically; the alternatives are listed with the scripticus use command that would restore each one.

Command conflicts

Every command is installed under three names: the bare command, a namespace-qualified form, and a fully-qualified form —

$ backup-verify --help                        # bare (convenient, can collide)
$ infra.backup-verify --help                  # namespace-qualified
$ infra.backup-rotate.backup-verify --help    # <namespace>.<package>.<command>

The fully-qualified form is guaranteed unique, so every installed command is always runnable no matter what else you install. The two shorter forms are conveniences: if another package provides the same command name, the most recently installed package takes the contested name (you are warned at install time, as above). To re-point a contested name at a specific package, name the shim you want changed:

$ scripticus use tools/old-backup backup-rotate        # the bare shim
$ scripticus use infra/other-tool infra.backup-rotate  # a namespaced shim

Snippets

Some code is not worth running — it is worth pasting. Argument parsing and signal traps are reusable in shape but different in every script, so a library cannot serve them: you want the text, to read and edit. That is a snippet, and snip prints one:

$ snip args.sh              # the snippet, on stdout
$ snip trap.sh >> deploy.sh # composition is the shell's job
$ snip args -c              # print it and put it on the clipboard

snip is installed alongside scripticus (and is also available as scripticus snip). The everyday form is <name>.<ext> — the extension picks the language, because one snippet often exists in several:

$ snip args.py
$ snip args.cpp

A bare snip args works when there is only one variant. When there is more than one — several languages, or two installed packages providing the same one — snip lists the candidates rather than guessing, and you pick with the fully namespaced form:

$ snip args
error: 'args' is ambiguous; it could be:
  infra/boilerplate:args.py
  infra/boilerplate:args.sh

$ snip infra/boilerplate:args.sh

Everything except the snippet itself goes to stderr, so snip x > file either gets the snippet or gets nothing. -c/--copy still prints the snippet, and where there is no clipboard (over SSH, say) it warns rather than failing.

Snippets are found with search like anything else — the search matches the snippet's name and description, and --language matches its file extension:

$ scripticus search trap
$ scripticus search --language python args

Libraries

Shell is the one common scripting language with no package manager for reusable code — every project reinvents a lib/ directory and a pile of source lines. A library package fills that: shell code you source rather than run.

Nothing needs installing by hand. A command that depends on a library gets it as an ordinary dependency, and can source it by name:

#!/usr/bin/env bash
scr_load infra/strings      # namespace/name — never a version

scr_strings_upper "shout"

scr_load is already in scope: Scripticus puts it there when it launches your command. In your own ad-hoc scripts — anything not installed as a package — source it first:

. "$SCRIPTICUS_LIB/scr_load.sh"
scr_load infra/strings

scripticus init exports SCRIPTICUS_LIB alongside the PATH entry, so this works in any shell once you have run it.

Loading is transitive (a library may load other libraries), and repeat loads are free — loading the same library twice, or via two different paths, does nothing the second time. A missing library returns non-zero rather than killing your script, so you can decide what to do:

if ! scr_load infra/optional-helpers; then
    echo "running without the helpers" >&2
fi

References never carry a version. The resolved closure already pins exactly one version of each package, so there is nothing to choose at load time; upgrading the library with scripticus update is enough, and every consumer picks up the new code without being rebuilt.

Libraries are sh or bash only. Python, Ruby, PowerShell and the rest already have pip, gem and PSGallery — Scripticus does not duplicate them. A sh library can be sourced by both sh and bash consumers; a bash library only by bash ones, and asking for anything else is refused when the install is resolved, not at 3am in production.

Authoring packages

Scaffolding

$ scripticus new bash my-cool-script -n infra

The namespace (-n/--namespace) is required: it is the namespace the package will be published under (a Gitea user or organisation), and it goes straight into the generated manifest. Namespaces are lower-case letters, digits, and dashes, and must begin with a letter.

This creates:

my-cool-script/
├── meta.toml
├── LICENSE
├── README.md
├── src/
│   └── main.sh
└── test/

Package names are lower-case with dashes (my-cool-script). Script files inside the package follow the conventions of their own language — a PowerShell package's named command scripts will be PascalCase.ps1, for example.

Because packages are plain scripts, the development loop is direct: cd into the directory and run them. To exercise the installed experience (shims, PATH) while developing:

$ scripticus install --editable .

which points the shim at your working directory.

The manifest

[package]
namespace = "infra"
name = "backup-rotate"
version = "1.2.0"
language = "bash"                 # sh, bash, python, powershell
description = "Rotate and prune backup sets"

[platforms]
os = ["linux", "macos"]
distros = ["debian", "arch"]      # optional, narrows os

[dependencies.tools]
requires = ["jq", "curl"]
optional = ["fzf"]

[dependencies.packages]
"infra/log-common" = "^2.0"

# Optional. If omitted, src/main.<ext> is the single entrypoint and the
# command name is the package name.
[commands]
backup-rotate = "src/main.sh"
backup-verify = "src/BackupVerify.sh"

Entrypoint rules:

• No [commands] table: src/ must contain main.<ext> (extension per the package language). Typing the package name runs it.

• [commands] table present: each entry maps a command name to a script path. Every listed command gets a shim on install.

  One name is unavailable: a command cannot be called app. Command names become the last segment of the installed shims (infra.my-tool.app), which macOS reads as an application-bundle extension and refuses to run. Package names are unaffected — infra/app providing backup is fine.

• [library] or [snippet.<name>] instead: the package provides no commands at all, and gets no shims. See the sections below.

Versions must be strict semver; publishes with non-conforming versions are rejected.

Authoring snippets

A snippet package declares [snippet.<name>] sections instead of [commands] — a package is one kind or the other. It has no language and no platforms: a snippet is never run, so its language is just the extension of the file it lives in, and one snippet can exist in as many languages as you write it in.

$ scripticus new --snippet argparse -n infra          # src/argparse.sh
$ scripticus new --snippet argparse -n infra --ext py # src/argparse.py

[package]
namespace = "infra"
name = "boilerplate"
version = "1.0.0"
description = "The bits nobody remembers exactly"

[snippet.args]
description = "Argument parsing"

[snippet.trap]
description = "Cleanup on exit"

boilerplate/
├── meta.toml
└── src/
    ├── args.sh      # snip args.sh
    ├── args.py      # snip args.py
    └── trap.sh      # snip trap.sh

The code lives in flat src/<name>.<ext> files, so shellcheck, syntax highlighting, and bash -n all work on real source rather than strings in TOML. You never list the languages: they are read off the filenames, at publish for the index and at install for snip. Add src/args.rb and snip args.rb works — including for languages Scripticus cannot run as commands (C++, Rust, Go). The two must agree, though: a declared snippet with no file, or a file with no section, is a packing error.

Authoring libraries

A library package declares a fieldless [library] table instead of [commands], and its entry point is src/load.<ext> — the sourced counterpart of src/main.<ext>:

$ scripticus new bash strings -n infra --lib

[package]
namespace = "infra"
name = "strings"
version = "1.0.0"
language = "bash"          # sh or bash — libraries are shell only
description = "String helpers"

[platforms]
os = ["linux", "macos"]

[library]

strings/
├── meta.toml
└── src/
    ├── load.sh      # sourced by scr_load infra/strings
    └── helpers.sh   # sourced by load.sh, if you want the split

load.sh is sourced into the caller's shell, so it should define functions and little else — anything at top level runs in someone else's script. Shell has one flat function namespace, so prefix your functions with something identifying (scr_strings_upper, not upper).

To source a sibling file, use $SCR_LIB_DIR, which is set to your package's directory before load.sh runs:

. "$SCR_LIB_DIR/src/helpers.sh"

A library may depend on other libraries and load them the same way any consumer does — scr_load other/library inside load.sh. The manifest lists nothing about what you source; only package dependencies, as usual.

Choose sh unless you need bash. An sh library can be sourced by everything in the family; a bash one only by bash consumers, and Scripticus refuses the mismatch when the install is resolved.

Manifest accuracy is your responsibility. Scripticus performs no correctness checks on the declared platforms or tool dependencies — neither at publish nor install. Nothing checks that a load.sh is actually sourceable, either. If the manifest is wrong, the package will be wrong, exactly as with a broken pyproject.toml or package.json. Test your packages.

Multi-file packages

A package is a directory, so an entrypoint can call sibling helper scripts or read sibling data files. The whole tree is packed and installed together, and a command's shim runs its entrypoint by absolute path from wherever you happen to be standing — it does not cd into the package, and the package directory is not added to PATH. So there is one rule for reaching a sibling:

Resolve siblings relative to your own script file, never relative to the current directory. A command runs with the user's working directory, not the package's, so ./helper.sh or a bare open("data.txt") looks in the wrong place. Anchor on the script's own location instead:

Language	Do this	Not this
bash	dir="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"; "$dir/helper.sh"	./helper.sh
python	Path(__file__).resolve().parent / "helper.py"	open("helper.py")
powershell	Join-Path $PSScriptRoot 'helper.ps1'	.\helper.ps1

This is ordinary script hygiene — the same code would break under any bin-dir installer — and it is the reason a plain ./helper.sh cannot be made to work no matter how the shim is written. Only helper scripts you want to expose as their own commands need a [commands] entry; internal helpers and data files just ride along in the tree.

Packing

To archive a package directory into a distributable artifact:

$ scripticus pack path/to/my-cool-script-proj
$ scripticus pack path/to/my-cool-script-proj -o builds   # write into builds/

The manifest is validated first; the archives land in the current directory unless -o/--output names another one (created if needed). One archive is produced per format the declared target platforms call for — .tar.gz covering the POSIX/macOS targets, .zip covering Windows — so a package targeting both produces two archives with identical content. Filenames carry wheel-style tags (name, version, platforms, language, with dashes in name/version normalised to underscores):

my_tool-1.2.0-linux.macos-python.tar.gz
my_tool-1.2.0-windows-python.zip

The filename is human-legible redundancy only; the manifest inside the archive is the source of truth.

Publishing

Publishing authenticates with a Gitea personal access token: create one in your Gitea user settings (it needs package-write scope), then log in to a remote by name:

$ scripticus login origin
Token: ********
Logged in to origin (https://scripts.example.com) as kevin-c

The first time you log in to a remote that isn't already in config.toml, give its URL too — this registers the remote as well as authenticating:

$ scripticus login origin https://scripts.example.com
Token: ********
Logged in to origin (https://scripts.example.com) as kevin-c

login verifies the token against the remote before storing it and prints the Gitea account it authenticated as, so a mistyped token fails right away rather than at your first publish. A rejected token, or a remote that can't be reached, is reported as such and nothing is written.

The token is stored in ~/.scripticus/credentials.toml, readable only by you, and sent with each publish — the registry itself holds no credentials. In CI, set the SCRIPTICUS_TOKEN environment variable instead; it takes precedence over the stored token.

publish doesn't pack for you — build the archive(s) first, then point publish at them by name-version, the same identifier pack just used for the filenames:

$ scripticus pack my-cool-script
$ scripticus publish my-cool-script-0.1.2

The argument is a path whose last segment is <name>-<version>; everything in that directory whose filename matches those fields (D26's tags — dashes in the name are matched against the filename's underscore form automatically) gets published. That means a package targeting both format groups publishes both archives from one command:

$ scripticus pack my-cool-script -o builds
$ scripticus publish builds/my-cool-script-0.1.2
Published my-cool-script 0.1.2:
  my_cool_script-0.1.2-linux.macos-bash.tar.gz
  my_cool_script-0.1.2-windows-powershell.zip

Every matched archive goes up in a single request, and the whole batch is published together or rejected together — the index service validates all of them before writing any blob to Gitea or committing anything, so there is no state where one variant is live and another silently isn't. If publish fails, nothing in that batch was published; fix the problem and re-run.

With more than one remote configured, publish targets the first one listed in config.toml unless you say otherwise:

$ scripticus publish builds/my-cool-script-0.1.2 --remote public

A published version is immutable. If you publish something broken:

$ scripticus yank infra/backup-rotate@1.2.0

Yanked versions disappear from search and latest resolution, but remain fetchable by anything that pins them directly (including lockfiles), so existing consumers do not break. yank takes an exact version (it is whole-version — a range is rejected), and needs a token for the namespace, exactly like publish.

Changed your mind? --undo reverses a yank — the same version becomes visible again, with no time limit on when you can do it:

$ scripticus yank --undo infra/backup-rotate@1.2.0

Platform variants

The same package version may be published as multiple platform/language variants (for example a linux/bash artifact and a windows/powershell artifact). The client automatically selects the variant matching the installing machine. POSIX/macOS artifacts are .tar.gz; Windows artifacts are .zip.

Configuration

Client configuration lives in ~/.scripticus/:

• config.toml — remotes as a [[remotes]] array of { name, url } entries; list order is priority (this list doubles as the bare-name namespace search path, and publish defaults to the first entry) — and other defaults. For example:

  [[remotes]]
  name = "origin"
  url = "https://scripts.example.com"
  
  [[remotes]]
  name = "public"
  url = "https://scripticus.example.org"
  

  An optional [tools] table tells Scripticus how to install missing required system tools. Scripticus encodes no package-manager logic — you provide the command, and the missing tool names are substituted into a {packages} placeholder (shell-quoted; appended if the placeholder is absent). It runs once through your shell, inheriting the environment, so proxies/mirrors/credentials come from the machine environment rather than this (org-distributable) file:

  [tools]
  install = "apt-get install -y {packages}"   # your machine's package manager
  escalate = "sudo"                            # optional; elevates only this command
  

  escalate is prepended to the tool command alone — Scripticus itself never needs privilege (its state is entirely under ~/.scripticus). Leave it out when already root or on Windows-as-admin. With no [tools] install configured, Scripticus never invokes a package manager: missing required tools abort the install (with the --skip-tools escape). Tool satisfiability in v1 is PATH presence only.

• credentials.toml — one Gitea access token per remote, keyed by URL and registered with scripticus login. Kept separate from config.toml so org-distributed configuration never carries a token.

• installed.lock — install state: every installed package, its exact resolved version and content hash, the full resolved dependency closure (with direct vs transitive marking), and provenance (remote or local file).

• bin/ — the shim directory on your PATH.
