# plaster-pastedeploy — A loader implementing the PasteDeploy syntax to be used by plaster.

License: permissive · Maintenance: active · Downloads: 2.4M/mo

## What it is and what it does

plaster_pastedeploy is a plugin for the plaster configuration framework that enables loading and parsing INI files according to the PasteDeploy standard. It implements the WSGI protocol interface, allowing applications to retrieve WSGI applications, filters, servers, and configuration settings from named sections in an INI file. The plugin bridges plaster's generic loader interface with PasteDeploy's specific INI syntax, supporting features like default value interpolation, environment variable injection, and logging configuration.

The package is typically used in web application frameworks (particularly Pyramid and other Pylons projects) to centralize application configuration. Developers call plaster.get_loader() with a URI pointing to an INI file, then use methods like get_wsgi_app() or get_settings() to retrieve configured components. The returned settings objects carry both local config and global defaults, plus a reference to the loader itself.

Use it for:

- Load WSGI application instances from INI configuration files in Pyramid or other Pylons-based web frameworks.
- Retrieve application settings and defaults from named sections in a PasteDeploy-format INI file for initialization.
- Configure WSGI filters and middleware chains by parsing filter definitions from an INI configuration source.
- Set up and start WSGI servers defined in an INI file without hardcoding server parameters in application code.
- Manage logging configuration alongside application settings by parsing logging setup from a single INI file.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

A plaster plugin that loads and parses INI configuration files using the PasteDeploy format, exposing methods to retrieve WSGI applications, filters, servers, and settings from named config sections.

Yes. The package has low install friction, no known vulnerabilities, permissive licensing, and active maintenance. It is a stable, production-ready solution for applications that already use plaster and PasteDeploy or are adopting the Pylons ecosystem's configuration conventions. Install it if your application needs to load WSGI configuration from INI files; skip it if you use a different configuration framework or format.

## Install

pip install plaster-pastedeploy
uv add plaster-pastedeploy
poetry add plaster-pastedeploy

## Installing plaster-pastedeploy

Before you install: Low install friction with only two runtime dependencies (plaster and PasteDeploy). The package is actively maintained with a recent commit history and supports current Python versions (3.7–3.10, including PyPy).

License in practice: Licensed under the MIT License (permissive), allowing free use, modification, and distribution with minimal restrictions.

Quickstart:

import plaster

loader = plaster.get_loader('development.ini', protocols=['wsgi'])
settings = loader.get_wsgi_app_settings()
app = loader.get_wsgi_app()

Verify before relying:

- Whether the package is actively maintained beyond the last release in November 2022 (last commit is recent but no new version released since then).
