title: 在Git项目中增加pre-commit校验 toc: true cover: 'https://img.paulzzh.com/touhou/random?22' date: 2021-10-10 15:50:46 categories: 技术杂谈 tags: [技术杂谈, Git]
有些编程语言提供了代码格式化检查等工具,如:Go、Rust等,我们可以在commit之前,对代码进行格式化检查,保证代码规范,而pre-commit
正是这样的工具;
<br/>
<!--more-->
pre-commit
官方网站:
pre-commit
支持的功能有:
需要注意的是:
pre-commit
这个工具不仅仅可以在pre-commit阶段执行,其实可以在git-hooks的任意阶段;
<br/>
pre-commit
brew install pre-commit
# 或者
pip install pre-commit --user
# 查看版本
pre-commit --version
pre-commit
除了需要在系统中安装pre-commit
,还需要在Git项目中安装:
cd <git-repo>
pre-commit install
# 卸载
pre-commit uninstall
上面的操作将会在项目的.git/hooks
下生成一个pre-commit
文件(覆盖原pre-commit文件),该hook会根据项目根目录下的.pre-commit-config.yaml
执行任务;
如果
vim .git/hooks/pre-commit
可以看到代码的实现,基本逻辑是利用pre-commit
文件去拓展更多的pre-commit;
安装/卸载其他阶段的hook:
pre-commit install
pre-commit uninstall
-t {pre-commit,pre-merge-commit,pre-push,prepare-commit-msg,commit-msg,post-checkout,post-commit,post-merge}
--hook-type {pre-commit,pre-merge-commit,pre-push,prepare-commit-msg,commit-msg,post-checkout,post-commit,post-merge}
# 如 pre-commit install --hook-type prepare-commit-msg
# 手动对所有的文件执行hooks,新增hook的时候可以执行,使得代码均符合规范。直接执行该指令则无需等到pre-commit阶段再触发hooks
pre-commit run --all-files
# 执行特定hooks
pre-commit run <hook_id>
# 将所有的hook更新到最新的版本/tag
pre-commit autoupdate
# 指定更新repo
pre-commit autoupdate --repo https://github.com/DoneSpeak/gromithooks
更多指令及指令参数请直接访问pre-commit官方网站;
<br/>
在Git仓库初始化pre-commit
:
cd <git-repo>
pre-commit install
touch .pre-commit-config.yaml
如下为一个基本的配置样例:
.pre-commit-config.yaml
# 该config文件为该项目的pre-commit的配置文件,用于指定该项目可以执行的git hooks
# 这是pre-commit的全局配置之一,fail_fast:遇到错误不会向下执行直接退出
fail_fast: false
repos:
# hook所在的仓库
- repo: https://github.com/pre-commit/pre-commit-hooks
# 仓库的版本,可以直接用tag或者分支,但分支是容易发生变化的
# 如果使用分支,则会在第一次安装之后不自动更新
# 通过 `pre-commit autoupdate`指令可以将tag更新到默认分支的最新tag
rev: v4.0.1
# 仓库中的hook id
hooks:
# 定义的hook脚本,在repo的.pre-commit-hooks.yaml中定义
- id: check-added-large-files
# 移除尾部空格符
- id: trailing-whitespace
# 传入参数,不处理makedown
args: [--markdown-linebreak-ext=md]
# 检查是否含有合并冲突符号
- id: check-merge-conflict
- repo: https://github.com/macisamuele/language-formatters-pre-commit-hooks
rev: v2.0.0
hooks:
- id: pretty-format-yaml
# https://github.com/macisamuele/language-formatters-pre-commit-hooks/blob/v2.0.0/language_formatters_pre_commit_hooks/pretty_format_yaml.py
# hook脚本需要的参数,可以在该hook脚本文件中看到
args: [--autofix, --indent, '2']
上面我们引入了两个配置:
在run
之后,pre-commit
会下载指定仓库代码,并安装配置所需要的运行环境;
配置完成之后可以通过pre-commit run --all-files
运行一下添加的hooks;
下表为.pre-commit-hooks.yaml
可选配置项:
key word | description |
---|---|
id |
the id of the hook - used in pre-commit-config.yaml. |
name |
the name of the hook - shown during hook execution. |
entry |
the entry point - the executable to run. entry can also contain arguments that will not be overridden such as entry: autopep8 -i . |
language |
the language of the hook - tells pre-commit how to install the hook. |
files |
(optional: default '' ) the pattern of files to run on. |
exclude |
(optional: default ^$ ) exclude files that were matched by files |
types |
(optional: default [file] ) list of file types to run on (AND). See Filtering files with types. |
types_or |
(optional: default [] ) list of file types to run on (OR). See Filtering files with types. new in 2.9.0. |
exclude_types |
(optional: default [] ) the pattern of files to exclude. |
always_run |
(optional: default false ) if true this hook will run even if there are no matching files. |
verbose |
(optional) if true , forces the output of the hook to be printed even when the hook passes. new in 1.6.0. |
pass_filenames |
(optional: default true ) if false no filenames will be passed to the hook. |
require_serial |
(optional: default false ) if true this hook will execute using a single process instead of in parallel. new in 1.13.0. |
description |
(optional: default '' ) description of the hook. used for metadata purposes only. |
language_version |
(optional: default default ) see Overriding language version. |
minimum_pre_commit_version |
(optional: default '0' ) allows one to indicate a minimum compatible pre-commit version. |
args |
(optional: default [] ) list of additional parameters to pass to the hook. |
stages |
(optional: default (all stages)) confines the hook to the commit , merge-commit , push , prepare-commit-msg , commit-msg , post-checkout , post-commit , post-merge , or manual stage. See Confining hooks to run at certain stages. |
关于开发hooks仓库:
<br/>
pre-commit 也提供了local
的hook,允许在entry
中配置执行指令或指向本地一个可执行的脚本文件,使用起来和husky
类似;
local hooks可以使用支持additional_dependencies
的语言或者 docker_image
/ fail
/ pygrep
/ script
/ system
;
在使用时,需要定义
repo: local
,即:本地仓库;
例如:
# 定义repo为local,表示该repo为本地仓库
- repo: local
hooks:
- id: pylint
name: pylint
entry: pylint
language: system
types: [python]
- id: changelogs-rst
name: changelogs must be rst
entry: changelog filenames must end in .rst
language: fail # fail 是一种用于通过文件名禁止文件的轻语言
files: 'changelog/.*(?<!\.rst)$'
上面给hooks定义了两个步骤:
