|
+## `cargo fmt` pre-commit hook
|
|
|
+
|
|
|
+To ensure every contributor uses the same code style, make sure
|
|
|
+you run `cargo fmt` before committing. You can force yourself to do
|
|
|
+this by creating a git `pre-commit` hook like the following:
|
|
|
+
|
|
|
+```
|
|
|
+#!/bin/bash
|
|
|
+diff="$(cargo fmt -- --check)
|
|
|
+result=$?
|
|
|
+
|
|
|
+if [[ "$result" -ne 0 ]]; then
|
|
|
+ echo "There are some code style issues. Run 'cargo fmt' to fix it."
|
|
|
+ exit 1
|
|
|
+fi
|
|
|
+
|
|
|
+exit 0
|
|
|
+```
|
|
|
+
|
|
|
+Place this script in `.git/hooks/pre-commit` and make sure it's
|
|
|
+executable by running `chmod +x .git/hooks/pre-commit`.
