gitignore-find

查找指定目录下所有被.gitignore文件忽略的路径，功能与git check-ignore **/*类似：

• 允许指定多个目录并检查其中所有的.gitignore文件
• 被.gitignore文件忽略的路径会尝试合并避免路径过多
• 超级快！

常见的用法是找出home目录下所有git仓库下忽略的目录用于从备份目录中排除

安装

目前只提供python扩展，使用pip从pypi安装

pip install gitignore-find

提供了一个简单的命令行程序find但只能使用源码构建cargo build --example find -r

运行

import gitignore_find
import logging

logging.basicConfig(level=5)
# logging.basicConfig(level=logging.DEBUG)

ignoreds = gitignore_find.find_ignoreds(
    ["."],
    excludes=["**/.git/**", "**/.cargo", "**/.vscode*"],
    exclude_ignoreds=["**/.venv/bin/**", "**/.env"],
)
print("\n".join(ignoreds))

性能

使用cargo bench测试当前目录22196个路径仅需要200ms
