**It's an ORM for your package managers, providing a nice python types for packages + installers.**
**This is a [Python library](https://pypi.org/project/pydantic-pkgr/) for installing & managing packages locally with a variety of package managers.**
It's designed for when `pip` dependencies aren't enough, and your app has to check for & install dependencies at runtime.
```shell
pip install pydantic-pkgr
```
> ✨ Built with [`pydantic`](https://pydantic-docs.helpmanual.io/) v2 for strong static typing guarantees and json import/export compatibility
> 📦 Provides consistent cross-platform interfaces for dependency resolution & installation at runtime
> 🌈 Integrates with [`django`](https://docs.djangoproject.com/en/5.0/) >= 4.0, [`django-ninja`](https://django-ninja.dev/), and OpenAPI + [`django-jsonform`](https://django-jsonform.readthedocs.io/) out-of-the-box
> 🦄 Uses [`pyinfra`](https://github.com/pyinfra-dev/pyinfra) / [`ansible`](https://github.com/ansible/ansible) for the actual install operations whenever possible (with internal fallbacks)
<sub><i>Built by <a href="https://github.com/ArchiveBox">ArchiveBox</a> to install & auto-update our extractor dependencies at runtime (<code>chrome</code>, <code>wget</code>, <code>curl</code>, etc.) on `macOS`/`Linux`/`Docker`.</i></sub>
<br/>
> [!WARNING]
> This is `BETA` software, the API is mostly stable but there may be minor changes later on.

# you can also define binaries as classes, making them usable for type checking
class CurlBinary(Binary):
name: str = 'curl'

curl.exec(cmd=['--version']) # curl 8.4.0 (x86_64-apple-darwin23.0) libcurl/8.4.0 ...
```
```python
from pydantic_pkgr import Binary, EnvProvider, PipProvider
# We also provide direct package manager (aka BinProvider) APIs
apt = AptProvider()
apt.install('wget')
print(apt.PATH, apt.get_abspaths('wget'), apt.get_version('wget'))
# even if packages are installed by tools we don't control (e.g. pyinfra/ansible/puppet/etc.)
from pyinfra.operations import apt
apt.packages(name="Install ffmpeg", packages=['ffmpeg'], _sudo=True)
# our Binary API provides a nice type-checkable, validated, serializable handle
ffmpeg = Binary(name='ffmpeg').load()
print(ffmpeg) # name=ffmpeg abspath=/usr/bin/ffmpeg version=3.3.0 is_valid=True ...
print(ffmpeg.loaded_abspaths) # show all the ffmpeg binaries found in $PATH (in case theres more than one available)
print(ffmpeg.model_dump_json()) # ... everything can also be dumped/loaded as json
print(ffmpeg.model_json_schema()) # ... all types provide OpenAPI-ready JSON schemas
```
### Supported Package Managers
**So far it supports `installing`/`finding installed`/~~`updating`/`removing`~~ packages on `Linux`/`macOS` with:**
- `apt` (Ubuntu/Debian/etc.)
- `brew` (macOS/Linux)
- `pip` (Linux/macOS/Windows)
- `npm` (Linux/macOS/Windows)
- `env` (looks for existing version of binary in user's `$PATH` at runtime)
- `vendor` (you can bundle vendored copies of packages you depend on within your source)
*Planned:* `docker`, `cargo`, `nix`, `apk`, `go get`, `gem`, `pkg`, *and more using `ansible`/[`pyinfra`](https://github.com/pyinfra-dev/pyinfra)...*
---
## Usage
```bash
pip install pydantic-pkgr
```
### [`BinProvider`](https://github.com/ArchiveBox/pydantic-pkgr/blob/main/pydantic_pkgr/binprovider.py#:~:text=class%20BinProvider)
**Implementations: `EnvProvider`, `AptProvider`, `BrewProvider`, `PipProvider`, `NpmProvider`**
This type represents a "provider of binaries", e.g. a package manager like `apt`/`pip`/`npm`, or `env` (which finds binaries in your `$PATH`).
`BinProvider`s implement the following interface:
* `.INSTALLER_BIN -> /opt/homebrew/bin/brew` provider's pkg manager location
* `.PATH -> PATHStr('/opt/homebrew/bin:/usr/local/bin:...')` where provider stores bins
* `get_packages(bin_name: str) -> InstallArgs(['curl', 'libcurl4', '...])` find pkg dependencies for a bin
- `install(bin_name: str)` install a bin using binprovider to install needed packages
- `load(bin_name: str)` find an existing installed binary
- `load_or_install(bin_name: str)` `->` `Binary` find existing / install if needed
- `get_version(bin_name: str) -> SemVer('1.0.0')` get currently installed version
- `get_abspath(bin_name: str) -> Path('/absolute/path/to/bin')` get installed bin abspath
* `get_abspaths(bin_name: str) -> [Path('/opt/homebrew/bin/curl'), Path('/other/paths/to/curl'), ...]` get all matching bins found
* `get_sha256(bin_name: str) -> str` get sha256 hash hexdigest of the binary
```python
import platform
from typing import List
from pydantic_pkgr import EnvProvider, PipProvider, AptProvider, BrewProvider
### Example: Finding an existing install of bash using the system $PATH environment
env = EnvProvider()
bash = env.load(bin_name='bash') # Binary('bash', provider=env)
print(bash.abspath) # Path('/opt/homebrew/bin/bash')
print(bash.version) # SemVer('5.2.26')
bash.exec(['-c', 'echo hi']) # hi
### Example: Installing curl using the apt package manager
apt = AptProvider()
curl = apt.install(bin_name='curl') # Binary('curl', provider=apt)
print(curl.abspath) # Path('/usr/bin/curl')
print(curl.version) # SemVer('8.4.0')
print(curl.sha256) # 9fd780521c97365f94c90724d80a889097ae1eeb2ffce67b87869cb7e79688ec
curl.exec(['--version']) # curl 7.81.0 (x86_64-pc-linux-gnu) libcurl/7.81.0 ...
### Example: Finding/Installing django with pip (w/ customized binpath resolution behavior)
pip = PipProvider(
abspath_handler={'*': lambda self, bin_name, **context: inspect.getfile(bin_name)}, # use python inspect to get path instead of os.which
)
django_bin = pip.load_or_install('django') # Binary('django', provider=pip)
print(django_bin.abspath) # Path('/usr/lib/python3.10/site-packages/django/__init__.py')
print(django_bin.version) # SemVer('5.0.2')
```
### [`Binary`](https://github.com/ArchiveBox/pydantic-pkgr/blob/main/pydantic_pkgr/binary.py#:~:text=class%20Binary)
This type represents a single binary dependency aka a package (e.g. `wget`, `curl`, `ffmpeg`, etc.).
It can define one or more `BinProvider`s that it supports, along with overrides to customize the behavior for each.
`Binary`s implement the following interface:
- `load()`, `install()`, `load_or_install()` `->` `Binary`
- `binprovider: InstanceOf[BinProvider]`
- `abspath: Path`
- `abspaths: List[Path]`
- `version: SemVer`
- `sha256: str`
```python
from pydantic_pkgr import BinProvider, Binary, BinProviderName, BinName, ProviderLookupDict, SemVer
class CustomBrewProvider(BrewProvider):
name: str = 'custom_brew'
def get_macos_packages(self, bin_name: str, **context) -> List[str]:
extra_packages_lookup_table = json.load(Path('macos_packages.json'))
return extra_packages_lookup_table.get(platform.machine(), [bin_name])
### Example: Create a re-usable class defining a binary and its providers
class YtdlpBinary(Binary):
name: BinName = 'ytdlp'
description: str = 'YT-DLP (Replacement for YouTube-DL) Media Downloader'
binproviders_supported: List[BinProvider] = [EnvProvider(), PipProvider(), AptProvider(), CustomBrewProvider()]
# customize installed package names for specific package managers
provider_overrides: Dict[BinProviderName, ProviderLookupDict] = {
'pip': {'packages': ['yt-dlp[default,curl-cffi]']}, # can use literal values (packages -> List[str], version -> SemVer, abspath -> Path, install -> str log)
'apt': {'packages': lambda: ['yt-dlp', 'ffmpeg']}, # also accepts any pure Callable that returns a list of packages
'brew': {'packages': 'self.get_macos_packages'}, # also accepts string reference to function on self (where self is the BinProvider)
}
ytdlp = YtdlpBinary().load_or_install()
print(ytdlp.binprovider) # BrewProvider(...)
print(ytdlp.abspath) # Path('/opt/homebrew/bin/yt-dlp')
print(ytdlp.abspaths) # [Path('/opt/homebrew/bin/yt-dlp'), Path('/usr/local/bin/yt-dlp')]
print(ytdlp.version) # SemVer('2024.4.9')
print(ytdlp.sha256) # 46c3518cfa788090c42e379971485f56d007a6ce366dafb0556134ca724d6a36
print(ytdlp.is_valid) # True
```
```python
from pydantic_pkgr import BinProvider, Binary, BinProviderName, BinName, ProviderLookupDict, SemVer
#### Example: Create a binary that uses Podman if available, or Docker otherwise
class DockerBinary(Binary):
name: BinName = 'docker'
binproviders_supported: List[BinProvider] = [EnvProvider(), AptProvider()]
provider_overrides: Dict[BinProviderName, ProviderLookupDict] = {
'env': {
# example: prefer podman if installed (falling back to docker)
'abspath': lambda: os.which('podman') or os.which('docker') or os.which('docker-ce'),
},
'apt': {
# example: vary installed package name based on your CPU architecture
'packages': {
'amd64': ['docker'],
'armv7l': ['docker-ce'],
'arm64': ['docker-ce'],
}.get(platform.machine(), 'docker'),
},
}
docker = DockerBinary().load_or_install()
print(docker.binprovider) # EnvProvider()
print(docker.abspath) # Path('/usr/local/bin/podman')
print(docker.abspaths) # [Path('/usr/local/bin/podman'), Path('/opt/homebrew/bin/podman')]
print(docker.version) # SemVer('6.0.2')
print(docker.is_valid) # True
# You can also pass **kwargs to override properties at runtime,
# e.g. if you want to force the abspath to be at a specific path:
custom_docker = DockerBinary(abspath='~/custom/bin/podman').load()
print(custom_docker.name) # 'docker'
print(custom_docker.binprovider) # EnvProvider()
print(custom_docker.abspath) # Path('/Users/example/custom/bin/podman')
print(custom_docker.version) # SemVer('5.0.2')
print(custom_docker.is_valid) # True
```
### [`SemVer`](https://github.com/ArchiveBox/pydantic-pkgr/blob/main/pydantic_pkgr/semver.py#:~:text=class%20SemVer)
```python
from pydantic_pkgr import SemVer
### Example: Use the SemVer type directly for parsing & verifying version strings
SemVer.parse('Google Chrome 124.0.6367.208+beta_234. 234.234.123') # SemVer(124, 0, 6367')
SemVer.parse('2024.04.05) # SemVer(2024, 4, 5)
SemVer.parse('1.9+beta') # SemVer(1, 9, 0)
str(SemVer(1, 9, 0)) # '1.9.0'
```
<br/>
> These types are all meant to be used library-style to make writing your own apps easier.
> e.g. you can use it to build things like: [`playwright install --with-deps`](https://playwright.dev/docs/browsers#install-system-dependencies))
<br/>

## Django Usage
The pydantic ecosystem helps us get auto-generated, type-checked Django fields & forms that support `BinProvider` and `Binary`.
> [!TIP]
> For the full Django experience, we recommend installing these 3 excellent packages:
> - [`django-admin-data-views`](https://github.com/MrThearMan/django-admin-data-views)
> - [`django-pydantic-field`](https://github.com/surenkov/django-pydantic-field)
> - [`django-jsonform`](https://django-jsonform.readthedocs.io/)
> `pip install pydantic-pkgr django-admin-data-views django-pydantic-field django-jsonform`
<br/>
### Django Model Usage: Store `BinProvider` and `Binary` entries in your model fields
```bash
pip install django-pydantic-field
```
*Fore more info see the [`django-pydantic-field`](https://github.com/surenkov/django-pydantic-field) docs...*
Example Django `models.py` showing how to store `Binary` and `BinProvider` instances in DB fields:
```python
from typing import List
from django.db import models
from pydantic import InstanceOf
from pydantic_pkgr import BinProvider, Binary, SemVer
from django_pydantic_field import SchemaField
class InstalledBinary(models.Model):
name = models.CharField(max_length=63)
binary: Binary = SchemaField()
binproviders: List[InstanceOf[BinProvider]] = SchemaField(default=[])
version: SemVer = SchemaField(default=(0,0,1))
```
And here's how to save a `Binary` using the example model:
```python
# find existing curl Binary in $PATH
curl = Binary(name='curl').load()
# save it to the DB using our new model
obj = InstalledBinary(
name='curl',
binary=curl, # store Binary/BinProvider/SemVer values directly in fields
binproviders=[env], # no need for manual JSON serialization / schema checking
min_version=SemVer('6.5.0'),
)
obj.save()
```
When fetching it back from the DB, the `Binary` field is auto-deserialized / immediately usable:
```
obj = InstalledBinary.objects.get(name='curl') # everything is transparently serialized to/from the DB,
# and is ready to go immediately after querying:
assert obj.binary.abspath == curl.abspath
print(obj.binary.abspath) # Path('/usr/local/bin/curl')
obj.binary.exec(['--version']) # curl 7.81.0 (x86_64-apple-darwin23.0) libcurl/7.81.0 ...
```
*For a full example see our provided [`django_example_project/`](https://github.com/ArchiveBox/pydantic-pkgr/tree/main/django_example_project)...*
<br/>
### Django Admin Usage: Display `Binary` objects nicely in the Admin UI
<img height="220" alt="Django Admin binaries list view" src="https://github.com/ArchiveBox/pydantic-pkgr/assets/511499/a9980217-f39e-434e-b266-20cd6feb17c3" align="top"><img height="220" alt="Django Admin binaries detail view" src="https://github.com/ArchiveBox/pydantic-pkgr/assets/511499/d4d9086e-c8f4-4b6e-8ee8-8c8a864715b0" align="top">
```bash
pip install pydantic-pkgr django-admin-data-views
```
*For more info see the [`django-admin-data-views`](https://github.com/MrThearMan/django-admin-data-views) docs...*
Then add this to your `settings.py`:
```python
INSTALLED_APPS = [
# ...
'admin_data_views'
'pydantic_pkgr'
# ...
]
# point these to a function that gets the list of all binaries / a single binary
PYDANTIC_PKGR_GET_ALL_BINARIES = 'pydantic_pkgr.views.get_all_binaries'
PYDANTIC_PKGR_GET_BINARY = 'pydantic_pkgr.views.get_binary'
ADMIN_DATA_VIEWS = {
"NAME": "Environment",
"URLS": [
{
"route": "binaries/",
"view": "pydantic_pkgr.views.binaries_list_view",
"name": "binaries",
"items": {
"route": "<str:key>/",
"view": "pydantic_pkgr.views.binary_detail_view",
"name": "binary",
},
},
# Coming soon: binprovider_list_view + binprovider_detail_view ...
],
}
```

## Examples
### Advanced: Implement your own package manager behavior by subclassing BinProvider
```python
from subprocess import run, PIPE
from pydantic_pkgr import BinProvider, BinProviderName, BinName, SemVer
class CargoProvider(BinProvider):
name: BinProviderName = 'cargo'
def on_setup_paths(self):
if '~/.cargo/bin' not in sys.path:
sys.path.append('~/.cargo/bin')
def on_install(self, bin_name: BinName, **context):
packages = self.on_get_packages(bin_name)
installer_process = run(['cargo', 'install', *packages.split(' ')], capture_output = True, text=True)
assert installer_process.returncode == 0
def on_get_packages(self, bin_name: BinName, **context) -> InstallArgs:
# optionally remap bin_names to strings passed to installer
# e.g. 'yt-dlp' -> ['yt-dlp, 'ffmpeg', 'libcffi', 'libaac']
return [bin_name]
def on_get_abspath(self, bin_name: BinName, **context) -> Path | None:
self.on_setup_paths()
return Path(os.which(bin_name))
def on_get_version(self, bin_name: BinName, **context) -> SemVer | None:
self.on_setup_paths()
return SemVer(run([bin_name, '--version'], stdout=PIPE).stdout.decode())
cargo = CargoProvider()
rg = cargo.install(bin_name='ripgrep')
print(rg.binprovider) # CargoProvider()
print(rg.version) # SemVer(14, 1, 0)
```

store Binary/BinProvider/SemVer values directly in fields\n binproviders=[env], # no need for manual JSON serialization / schema checking\n min_version=SemVer('6.5.0'),\n)\nobj.save() \n```\n\nWhen fetching it back from the DB, the `Binary` field is auto-deserialized / immediately usable:\n```\nobj = InstalledBinary.objects.get(name='curl') # everything is transparently serialized to/from the DB,\n # and is ready to go immediately after querying:\nassert obj.binary.abspath == curl.abspath\nprint(obj.binary.abspath) # Path('/usr/local/bin/curl')\nobj.binary.exec(['--version']) # curl 7.81.0 (x86_64-apple-darwin23.0) libcurl/7.81.0 ...\n```\n*For a full example see our provided [`django_example_project/`](https://github.com/ArchiveBox/pydantic-pkgr/tree/main/django_example_project)...*\n\n<br/>\n\n### Django Admin Usage: Display `Binary` objects nicely in the Admin UI\n\n<img height=\"220\" alt=\"Django Admin binaries list view\" src=\"https://github.com/ArchiveBox/pydantic-pkgr/assets/511499/a9980217-f39e-434e-b266-20cd6feb17c3\" align=\"top\"><img height=\"220\" alt=\"Django Admin binaries detail view\" src=\"https://github.com/ArchiveBox/pydantic-pkgr/assets/511499/d4d9086e-c8f4-4b6e-8ee8-8c8a864715b0\" align=\"top\">\n\n```bash\npip install pydantic-pkgr django-admin-data-views\n```\n*For more info see the [`django-admin-data-views`](https://github.com/MrThearMan/django-admin-data-views) docs...*\n\nThen add this to your `settings.py`:\n```python\nINSTALLED_APPS = [\n #
