一个Git Commit Message模板

一个统一的commit消息模板可以约束团队成员使用一致的方式提交变更信息，这样也方便集成工具进行合规检查。

通常来讲，commit信息应该包含如下内容：

<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

type表示commit类型，可选值如下：

1.feat: A new feature

2.fix: A bug fix

3.docs: Documentation only changes

4.style: Changes that do not affect the meaning of the code (white-space, formatting, etc)

5.refactor: A code change that neither fixes a bug nor adds a feature

6.perf: A code change that improves performance

7.test: Adding missing tests or correcting existing tests

8.build: Changes that affect the build system or external dependencies (e.g: gulp, npm)

9.ci:Changes to our CI configuration files and scripts (e.g: Travis, Circle, BrowserStack)

10.chore: Other changes that don’t modify src or test files

11.revert: Reverts a previous commit

scope表示影响范围，如：route, component, utils, build等

subject表示commit概述，建议符合50/72 formatting

body表示具体修改的内容，可以分为多行，每一行建议符合50/72 formatting

footer是一些备注信息, 通常是BREAKING CHANGE或修复的BUG链接，如：issue #123

变更消息模板可以通过文件的方式固话下来，这样在每次提交变更的时候参照模板填写对应的信息。

一个完整的模板内容如下：

# head: <type>(<scope>): <subject>
# - type: feat, fix, docs, style, refactor, perf, test, build, ci, chore, revert
# - scope: can be empty (eg. if the change is a global or difficult to assign to a single component), e.g: route, component, utils, build...
# - subject: start with verb (such as 'change'), 50-character line
#
# body: 72-character wrapped. Multiple lines separated by “-”, This should answer:
# * Why was this change necessary?
# * How does it address the problem?
# * Are there any side effects?
#
# footer:
# - Include a link to the ticket, if any.
# - BREAKING CHANGE
#
# e.g:
# <type>(<scope>): <subject>
# <BLANK LINE>
# <body>
# <BLANK LINE>
# <footer>
#
# types:
#
# feat:     A new feature
# fix:      A bug fix
# docs:     Documentation only changes
# style:    Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
# refactor: A code change that neither fixes a bug nor adds a feature
# perf:     A code change that improves performance
# test:     Adding missing tests or correcting existing tests
# build:    Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
# ci:       Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
# chore:    Other changes that don't modify src or test files
# revert:   Reverts a previous commit

可以将上述模板信息保存在文件"~/.gitmessage "中并添加为git的commit模板：

修改 ~/.gitconfig，添加:

[commit]
template = ~/.gitmessage
