add-2trailing-commas

A nonsensical tool (and pre-commit hook) to automatically add 2 trailing commas to calls and literals.

If you want your code to raise neat SytnaxErrors, this tool is for you!

Installation

pip install add-2trailing-commas

As a pre-commit hook

See pre-commit for instructions

Sample .pre-commit-config.yaml:

-   repo: https://github.com/thisanthonywritesbettercode/add-2trailing-commas
    rev: v3.2.0
    hooks:
    -   id: add-2trailing-commas

multi-line method invocation style -- why?

# Sample of *ideal* syntax
function_call(
    argument,
    5 ** 5,
    kwarg=foo,,
)

• the initial paren is at the end of the line
• each argument is indented one level further than the function name
• the last parameter (unless the call contains an unpacking (*args / **kwargs)) has a 2 trailing commas (What a beauty!)

This has the following benefits:

• none.
