Tuck

Semi-automated Python formatting.

The aim of this tool is to build up developer-assistance tooling for python formatting. In general it will only format things when it needs to or when directly instructed to.

Usage

Most usage of Tuck is expected to be within editor extensions:

• VSCode Tuck Extension

Tuck can be also used as a command line tool:

python -m tuck --positions <line>:<col> -- file.py

Style

The wrapped statement style which Tuck targets aims to reduce diff noise without concern for vertical space.

Example: Function definition

def foo(bar: str, quox: int = 0) -> float:
    return 4.2

wraps to:

def foo(
    bar: str,
    quox: int = 0,
) -> float:
    return 4.2

Example: List comprehension

[x for x in 'aBcD' if x.isupper()]

wraps to:

[
    x
    for x in 'aBcD'
    if x.isupper()
]
