# pyproject-installer
This tool is intended for build, install, run or management of dependencies
sources of Python project in source tree within network-isolated environments.
## Description
- Supported platform: Unix.<br>
Currently, platform-specific parts:
- pipe is used for calling build backend hooks in subprocess
- script wrappers are generated only for Unix systems
- OS environment of this project is a `network-isolated` environment, which
implies that a local loopback interface is the only available network
interface. Thus, `pyproject-installer` doesn't perform any network activity
(e.g. it doesn't install build dependencies specified via PEP518 configuration
or PEP517's `get_requires_for_*` hooks). This also makes it difficult or
impossible to create an isolated Python environment for calling build backend
hooks specified in PEP517, therefore, current Python environment is the only
available environment.
- Source tree can be either checkout of VCS or unpacked source distribution.
- An installation result will be consumed by external tool like RPM.<br>
The main usage of `pyproject-installer` looks like:
```
external tool => (pyproject-installer: build => install to destdir) => external tool packages destdir
```
Therefore, there is no need to build intermediate source distribution for
build wheel, only `build_wheel` backend's hook is actually called.
Note: an installation into Python virtual environment is also supported, but
only the manual uninstallation of such packages is possible (tools should
refuse an uninstallation of distribution with missing `RECORD` file).
- Only stdlib or vendored dependencies can be used in runtime for bootstrapping
any Python project.<br>
Current vendored packages:
- `tomli` (used for parsing `pyproject.toml` configuration file).
Note: `tomli` is the part of stdlib since Python 3.11.
- `packaging` (used for parsing PEP508 dependencies)
- Installation of build dependencies is up to the caller.<br>
These dependencies of Python projects are managed externally with system
package managers like `apt` or `dnf`. [External source](#management-of-dependencies-sources) of upstream's
dependencies may be used for provision of formatted list of dependencies to external tools.
- There is no post-installation bytecompilation.<br>
PEP427 says that wheel installers should compile any installed .py to .pyc.
External tools like RPM already provide Python bytecompilation means, which
compile for multiple optimization levels at a time. No point to compile
modules twice.
- RECORD file is not installed.<br>
https://peps.python.org/pep-0627/#optional-record-file:
> Specifically, the RECORD file is unnecessary when projects are installed by
a Linux system packaging system, which has its own ways to keep track of
files, uninstall them or check their integrity. Having to keep a RECORD file
in sync with the disk and the system package database would be unreasonably
fragile, and no RECORD file is better than one that does not correspond to
reality.
- INSTALLER file is not installed by default(optional).<br>
https://peps.python.org/pep-0627/#optional-installer-file:
> The INSTALLER file is also made optional, and specified to be used for
informational purposes only. It is still a single-line text file containing
the name of the installer.
https://packaging.python.org/en/latest/specifications/recording-installed-packages/#the-installer-file:
> This value should be used for informational purposes only. For example, if a
tool is asked to uninstall a project but finds no RECORD file, it may
suggest that the tool named in INSTALLER may be able to do the
uninstallation.
- Built distribution can be checked within Python virtual environment with the
help of `run` command.
- Project's dependencies sources can be managed (i.e. stored, synced, verified
or evaluated) with the help of `deps` command.
## Usage
### Build
Build project from source tree in current Python environment according to
PEP517. This doesn't trigger installation of project's build dependencies.
```
python -m pyproject_installer build
```
Build positional arguments:
<pre>
<em><strong>description</strong></em>: source directory
<em><strong>default</strong></em>: current working directory
<em><strong>example</strong></em>: python -m pyproject_installer build .
</pre>
Build options:
<pre>
<em><strong>name</strong></em>: --outdir OUTDIR, -o OUTDIR
<em><strong>description</strong></em>: output directory for built wheel
<em><strong>default</strong></em>: {srcdir}/dist
<em><strong>example</strong></em>: python -m pyproject_installer build --outdir ~/outdir
</pre>
Upon successful build `pyproject_installer` dumps wheel filename into
`{OUTDIR}/.wheeltracker`.
<pre>
<em><strong>name</strong></em>: --sdist
<em><strong>description</strong></em>: build source distribution(sdist) instead of binary
one(wheel).
<em><strong>note</strong></em>: installer supports only wheel format.

</pre>
<pre>
<em><strong>name</strong></em>: --backend-config-settings BACKEND_CONFIG_SETTINGS
<em><strong>description</strong></em>: ad-hoc configuration for build backend as dumped JSON dictionary
<em><strong>default</strong></em>: None
Example of passing <em><strong>config_settings</strong></em> for setuptools>=64.0.0:
python -m pyproject_installer build --backend-config-settings='{"--build-option": ["--python-tag=sometag", "--build-number=123"]}'
Example of passing <em><strong>config_settings</strong></em> for setuptools<64.0.0:
python -m pyproject_installer build --backend-config-settings='{"--global-option": ["--python-tag=sometag", "--build-number=123"]}'
Example of passing <em><strong>config_settings</strong></em> for pdm backend:
python -m pyproject_installer build --backend-config-settings='{"--python-tag": "sometag"}'
</pre>
### Install
Install project built in wheel format. This doesn't trigger installation of
project's runtime dependencies.
```
python -m pyproject_installer install
```
Install positional arguments:
<pre>
<em><strong>description</strong></em>: wheel file to install
<em><strong>default</strong></em>: contructed as directory {cwd}/dist and wheel filename read from
{cwd}/dist/.wheeltracker
<em><strong>example</strong></em>: python -m pyproject_installer install wheel.whl
</pre>
Install options:
<pre>
<em><strong>name</strong></em>: --destdir DESTDIR, -d DESTDIR
<em><strong>description</strong></em>: Wheel installation root will be prepended with destdir
<em><strong>default</strong></em>: /
<em><strong>example</strong></em>: python -m pyproject_installer install --destdir ~/destdir
</pre>
<pre>
<em><strong>name</strong></em>: --installer INSTALLER
<em><strong>description</strong></em>: Name of installer to be recorded in dist-info/INSTALLER
<em><strong>default</strong></em>: None, INSTALLER will be omitted
<em><strong>example</strong></em>: python -m pyproject_installer install --installer custom_installer
</pre>
<pre>
<em><strong>name</strong></em>: --no-strip-dist-info
<em><strong>description</strong></em>: Don't strip dist-info. By default only <em><strong>METADATA</strong></em>
and <em><strong>entry_points.txt</strong></em> files are allowed in <em>dist-info</em> directory.
<em><strong>note</strong></em>: <em><strong>RECORD</strong></em> is unconditionally filtered out.
<em><strong>default</strong></em>: False
<em><strong>example</strong></em>: python -m pyproject_installer install --no-strip-dist-info
</pre>
### Run
Run command within Python virtual environment that has access to system and user
site packages, their console scripts and installed built package.
```
python -m pyproject_installer run
```
Run positional arguments:
<pre>
<em><strong>description</strong></em>: command to run within virtual environment
<em><strong>example</strong></em>: python -m pyproject_installer run pytest
</pre>
Dash note:
> https://docs.python.org/3/library/argparse.html#arguments-containing
If you have positional arguments that must begin with - and don't look like
negative numbers, you can insert the pseudo-argument '--' which tells
`parse_args()` that everything after that is a positional argument:
```
python -m pyproject_installer run -- pytest -vra
```
Run options:
<pre>
<em><strong>name</strong></em>: --wheel WHEEL
<em><strong>description</strong></em>: wheel file to install into virtual environment
<em><strong>default</strong></em>: contructed as directory {cwd}/dist and wheel filename read from
{cwd}/dist/.wheeltracker

## Comparison with other tools
`pyproject-installer` consists of builder and installer, both provide
*only necessary* and *sufficient* functionality.
### builder
Functionally, today's builder is similar to [build](https://pypi.org/project/build).<br>
The key differences are:
- highly specialized defaults (see [description](#Description))
- highly specialized features to drop extra runtime dependencies like
`pep517`. No point to vendor `pep517` to call only `build_wheel` backend hook
in subprocess.
### installer
Functionally, today's installer is similar to [installer](https://pypi.org/project/installer).<br>
The key differences are:
- highly specialized defaults and features (see [description](#Description))
Both can be replaced with [pip](https://pypi.org/project/pip). But again, no
point to use full-featured complex `pip` to highly specialized task.
## Bootstrap
There is a self-hosted build backend to avoid dependency on any other backend.
For example, bootstrap can be done as:
```console
export PYTHONPATH=$(pwd)/src
python -m pyproject_installer build
python -m pyproject_installer install --destdir=/rootdir
```
## Tests
- unit tests can be run as:
```
pytest tests/unit
```
- integration tests (require internet connection and `git` tool) can be run as:
```
pytest tests/integration
```
## License
Distributed under the terms of the **MIT** license, `pyproject-installer` is
free and open source software.

No point to vendor `pep517` to call only `build_wheel` backend hook\n in subprocess.\n\n### installer\n\nFunctionally, today's installer is similar to [installer](https://pypi.org/project/installer).<br>\nThe key differences are:\n- highly specialized defaults and features (see [description](#Description))\n\nBoth can be replaced with [pip](https://pypi.org/project/pip). But again, no\npoint to use full-featured complex `pip` to highly specialized task.\n\n\n## Bootstrap\nThere is a self-hosted build backend to avoid dependency on any other backend.\n\nFor example, bootstrap can be done as:\n```console\nexport PYTHONPATH=$(pwd)/src\npython -m pyproject_installer build\npython -m pyproject_installer install --destdir=/rootdir\n```\n\n## Tests\n- unit tests can be run as:\n ```\n pytest tests/unit\n ```\n- integration tests (require internet connection and `git` tool) can be run as:\n ```\n pytest tests/integration\n ```\n\n## License\n\nDistributed under the terms of the **MIT** license, `pyproject-installer` is\nfree and open source software.\n",
