Project description
auto-walrus
auto-walrus
A tool and pre-commit hook to automatically apply the awesome walrus operator.
Installation
pip install auto-walrus
Usage as a pre-commit hook
See pre-commit for instructions
Sample .pre-commit-config.yaml:
- repo: https://github.com/MarcoGorelli/auto-walrus
rev: v0.1.8
hooks:
- id: auto-walrus
Command-line example
auto-walrus myfile.py
- n = 10
- if n > 3:
+ if (n := 10) > 3:
Configuration
Using the walrus operator can result in longer lines. Lines longer than what you
pass to --line-length won't be rewritten to use walrus operators.
E.g.
auto-walrus myfile_1.py myfile_2.py --line-length 89
You can turn off rewrites by adding a # no-walrus comment, either when you
assign a variable, or when you use it in an if or where statement, e.g.:
n = 10 # no-walrus
if n > 3:
print(n)
