[Python-Dev] Adding a toml module to the standard lib? (original) (raw)

Hi,

I'd like to discuss the idea to add a module to parse TOML toml-lang to Python's standard library.

PEP-0518 -- Specifying Minimum Build System Requirements for Python Projects pep suggests to store build system dependencies in pyproject.toml, yet Python itself does not support this format. Various packaging related projects like pip and pipenv already support PEP-0518 and vendored one of the existing TOML libraries in order to read pyproject.toml files.

Besides that, TOML seems a better alternative to .cfg/.ini, .json -- both of which are already supported by Python's standard lib and parsing/dumping TOML properly is tricky enough to solve it properly requirements.

There are a couple of TOML implementations out there [toml, pytoml, tomlkit] and one would have to find out which one to prefer and migrate into the stdlib.

If the result of this discussion is leaning towards adding TOML, I'd volunteer to do it. This includes: coordinating with the maintainer of the chosen library, writing the PEP (hopefully with some help) and maintain the module for at least two years.

Cheers,

Bastian
