Pep 518 (build System Requirements)
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
PEP 518 introduces a standardized way to specify build system requirements for Python projects, allowing tools like pip to understand and handle the required build dependencies effectively. It defines a 'pyproject.toml' configuration file where the build system's requirements and backend are declared, fostering better isolation and reproducibility of builds.
Key Features
- Defines a uniform format for specifying build dependencies using 'pyproject.toml'.
- Enables build backends to declare their requirements explicitly.
- Facilitates improved isolation of build environments from runtime environments.
- Supports various build systems beyond setuptools, such as Poetry and Flit.
- Enhances reproducibility and simplifies automation of Python package builds.
Pros
- Standardizes the way build dependencies are specified, improving interoperability.
- Enhances build reproducibility and environment isolation.
- Flexibility to support multiple build backends.
- Streamlines dependency management during package building.
Cons
- Introduces additional complexity for developers unfamiliar with 'pyproject.toml'.
- Requires tools and packages to adopt the new specification to realize full benefits.
- Transitioning legacy projects may involve some effort.
