首页导航图标存放在 `scripts/assets` 目录中,如果你的备忘清单定义为 `docs/cron.md`,那么你的图标就定义为 `cron.svg` 存放到 `scripts/assets` 目录中,重新编译首页当行菜单就拥有了图标。
|
||||
|
||||
- 图标存放在 [`scripts/assets`](https://github.com/jaywcjlove/reference/blob/main/scripts/assets) 目录中
|
||||
- 图片名称与清单名称保持一致 `cron.md` -> `cron.svg` (注意大小写)
|
||||
- SVG 图标尺寸 `<svg height="1em" width="1em"`
|

- SVG 图标颜色使用继承颜色值 `<svg fill="currentColor"`

|
||||
===
|
||||
|
||||

|
||||
|
||||
入门
|
||||

|
||||
|
||||
如果你没有安装 PIP,你可以从这个页面下载并安装它:https://pypi.org/project/pip/
|
||||
|
||||
### 入门
|
||||
<!--rehype:wrap-class=row-span-4-->
|
||||
|
||||
- 创建虚拟环境
|
||||
```bash
|
||||
$ py -m venv myproject # Windows
|
||||
$ python -m venv myproject # Unix/MacOS
|
||||
```
|
||||
- 其中包含子文件夹和文件,如下所示
|
||||
```bash
|
||||
myproject
|
||||
├┈Include
|
||||
├┈Lib
|
||||
├┈Scripts
|
||||
╰┈pyvenv.cfg
|
||||
```
|
||||
- 以下命令来激活环境
|
||||
```bash
|
||||
# Windows:
|
||||
myproject\Scripts\activate.bat
|
||||
# Unix/MacOS:
|
||||
source myproject/bin/activate
|
||||
```
|
||||
- 提示符中看到以下结果:
|
||||
```bash
|
||||
# Windows:
|
||||
(myproject) C:\Users\Your Name>
|
||||
# Unix/MacOS:
|
||||
(myproject) ... $
|
||||
```
|
||||
- 安装 Django
|
||||
```bash
|
||||
# Windows:
|
||||
(myproject) C:\Users\Name>py -m pip install Django
|
||||
# Unix/MacOS:
|
||||
(myproject) ... $ python -m pip install Django
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
<!--rehype:className=style-timeline-->
|
||||
|
||||
### 创建项目
|
||||
<!--rehype:wrap-class=row-span-3-->
|
||||
|
||||
```bash
|
||||
$ django-admin startproject myworld
|
||||
```
|
||||
|
||||
创建了一个 `myworld` 文件夹,内容如下:
|
||||
|
||||
```bash
|
||||
myworld
|
||||
├┈ manage.py
|
||||
╰┈ myworld/
|
||||
├┈ __init__.py
|
||||
├┈ asgi.py
|
||||
├┈ settings.py
|
||||
├┈ urls.py
|
||||
╰┈ wsgi.py
|
||||
```
|
||||
|
||||
运行 Django 项目
|
||||
|
||||
```bash
|
||||
$ py manage.py runserver # Windows
|
||||
$ python manage.py runserver # Unix/MacOS
|
||||
```
|
||||
|
||||
打开一个新的浏览器窗口并在地址栏中输入 127.0.0.1:8000
|
||||
|
||||
### 检查 Django 版本
|
||||
|
||||
```bash
|
||||
(myproject) C:\Users\Your Name>django-admin --version
|
||||
# 4.0.3
|
||||
```
|
||||
|
||||
### 创建应用
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```bash
|
||||
$ py manage.py startapp members
|
||||
```
|
||||
|
||||
项目中创建了一个名为 `members` 的文件夹,内容如下:
|
||||
|
||||
```bash
|
||||
myworld
|
||||
├┈ manage.py
|
||||
├┈ myworld/
|
||||
╰┈ members/
|
||||
├┈ migrations/
|
||||
┆ ╰┈ __init__.py
|
||||
├┈ __init__.py
|
||||
├┈ admin.py
|
||||
├┈ apps.py
|
||||
├┈ models.py
|
||||
├┈ tests.py
|
||||
╰┈ views.py
|
||||
```
|
||||
|
||||
首先,看一下名为 `views.py` 的文件。这是我们收集发送回正确响应所需的信息的地方。
|
||||
|
||||
### 应用目录介绍
|
||||
|
||||
- `Django` 接收 URL,检查 `urls.py` 文件,并调用与 URL 匹配的视图。
|
||||
- 位于 `views.py` 中的视图检查相关模型。
|
||||
- 模型是从 `models.py` 文件中导入的。
|
||||
- 然后视图将数据发送到模板文件夹中的指定模板。
|
||||
- 模板包含 `HTML` 和 `Django` 标记,并使用数据将完成的 `HTML` 内容返回给浏览器
|
||||
|
||||
### 视图
|
||||
|
||||
Django 视图是接受 `http` 请求并返回 `http` 响应的 `Python` 函数,就像 `HTML` 文档一样。
|
||||
|
||||
使用 `Django` 的网页充满了不同任务和任务的视图。
|
||||
|
||||
视图通常放在一个名为 `views.py` 的文件中,该文件位于应用程序的文件夹中。
|
||||
|
||||
您的 `members` 文件夹中有一个 `views.py`,如下所示:
|
||||
|
||||
```PY
|
||||
from django.shortcuts import render
|
||||
|
||||
# Create your views here.
|
||||
```
|
||||
|
||||
找到它并打开它,并将内容替换为:
|
||||
|
||||
```PY
|
||||
from django.shortcuts import render
|
||||
from django.http import HttpResponse
|
||||
|
||||
def index(request):
|
||||
return HttpResponse("Hello world!")
|
||||
```
|
||||
|
||||
这是一个关于如何将响应发送回浏览器的简单示例。
|
||||
|
||||
但是我们如何执行视图呢? 好吧,我们必须通过 URL 调用视图。
|
||||
|
||||
### URLs
|
||||
|
||||
在与 `views.py` 文件相同的文件夹中创建一个名为 `urls.py` 的文件,并在其中输入以下代码:
|
||||
|
||||
```py
|
||||
from django.urls import path
|
||||
from . import views
|
||||
urlpatterns = [
|
||||
path('', views.index, name='index'),
|
||||
]
|
||||
```
|
||||
|
||||
刚刚创建的 `urls.py` 文件是特定于成员应用程序的。我们还必须在根目录 `myworld` 中进行一些路由。
|
||||
|
||||
在 `myworld` 文件夹中有一个名为 `urls.py` 的文件,打开该文件并在 `import` 语句中添加 `include` 模块,并在列表中添加一个 `path()` 函数。文件将如下所示:
|
||||
|
||||
```py
|
||||
from django.contrib import admin
|
||||
from django.urls import include, path
|
||||
|
||||
urlpatterns = [
|
||||
path('members/', include('members.urls')),
|
||||
path('admin/', admin.site.urls),
|
||||
]
|
||||
```
|
||||
|
||||
如果服务器未运行,请导航到 `/myworld` 文件夹并在命令提示符下执行此命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py runserver
|
||||
```
|
||||
|
||||
在浏览器窗口的地址栏中输入 `127.0.0.1:8000/members/`
|
||||
|
||||
### 模板
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
在 `members` 文件夹中创建一个 `templates` 文件夹,并创建一个名为 `myfirst.html` 的 `HTML` 文件。文件结构应该是这样的:
|
||||
|
||||
```bash
|
||||
myworld
|
||||
├┈ manage.py
|
||||
├┈ myworld/
|
||||
╰┈ members/
|
||||
╰┈ templates/
|
||||
╰┈ myfirst.html
|
||||
```
|
||||
|
||||
打开 `HTML` 文件并插入以下内容:
|
||||
|
||||
```html
|
||||
<!DOCTYPE html>
|
||||
<html>
|
||||
<body>
|
||||
<h1>Hello World!</h1>
|
||||
<p>欢迎来到我的第一个 Django 项目!</p>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
修改视图 `members/views.py`
|
||||
|
||||
```py
|
||||
from django.http import HttpResponse
|
||||
from django.template import loader
|
||||
|
||||
def index(request):
|
||||
template = loader.get_template('myfirst.html')
|
||||
return HttpResponse(template.render())
|
||||
```
|
||||
|
||||
#### 更改设置
|
||||
|
||||
为了能够处理比“Hello World!”更复杂的东西,我们必须告诉 `Django` 一个新的应用程序已创建
|
||||
|
||||
这是在 `myworld` 文件夹的 `myworld/settings.py` 文件中完成的。查找 `INSTALLED_APPS[]` 列表并添加成员应用程序,如下所示:
|
||||
|
||||
```py
|
||||
INSTALLED_APPS = [
|
||||
'django.contrib.admin',
|
||||
'django.contrib.auth',
|
||||
'django.contrib.contenttypes',
|
||||
'django.contrib.sessions',
|
||||
'django.contrib.messages',
|
||||
'django.contrib.staticfiles',
|
||||
'members.apps.MembersConfig'
|
||||
]
|
||||
```
|
||||
|
||||
然后运行这个命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py migrate
|
||||
```
|
||||
|
||||
通过导航到 `/myworld` 文件夹启动服务器并执行以下命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py runserver
|
||||
```
|
||||
|
||||
在浏览器窗口的地址栏中输入 127.0.0.1:8000/members/
|
||||
|
||||
### 创建表(模型)
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
在 `/members/` 文件夹中,打开 `models.py` 文件。要在我们的数据库中添加成员表,首先创建一个成员类,并描述其中的表字段:
|
||||
|
||||
```py
|
||||
from django.db import models
|
||||
|
||||
class Members(models.Model):
|
||||
firstname = models.CharField(max_length=255)
|
||||
lastname = models.CharField(max_length=255)
|
||||
```
|
||||
|
||||
然后导航到 `/myworld/` 文件夹并运行以下命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py makemigrations members
|
||||
# Migrations for 'members':
|
||||
# members\migrations\0001_initial.py
|
||||
# - Create model Members
|
||||
```
|
||||
|
||||
创建一个包含任何新更改的文件并将该文件存储在 `/migrations/` 文件夹中。下次运行 `py manage.py migrate` 时,Django 将根据迁移文件夹中新文件的内容创建并执行一条 SQL 语句。运行迁移命令:
|
||||
|
||||
```bash
|
||||
$ py manage.py migrate
|
||||
```
|
||||
|
||||
从模型创建的 SQL 语句是:
|
||||
|
||||
```sql
|
||||
CREATE TABLE "members_members" (
|
||||
"id" INT NOT NULL PRIMARY KEY AUTOINCREMENT,
|
||||
"firstname" varchar(255) NOT NULL,
|
||||
"lastname" varchar(255) NOT NULL
|
||||
);
|
||||
```
|
||||
|
||||
Django 模板

|
||||
|
||||
### 模板变量
|
||||
<!--rehype:wrap-class=col-span-2 row-span-2-->
|
||||
|
||||
```django
|
||||
<!-- template.html -->
|
||||
<h1>你好 {{ firstname }},你好吗?</h1>
|
||||
```
|
||||
|
||||
在视图 (`views.py`) 中创建变量,上面示例中的变量 `firstname` 通过视图发送到模板:
|
||||
|
||||
```py
|
||||
from django.http import HttpResponse
|
||||
from django.template import loader
|
||||
|
||||
def testing(request):
|
||||
template = loader.get_template('template.html')
|
||||
context = {
|
||||
'firstname': '狂徒张三',
|
||||
}
|
||||
return HttpResponse(template.render(context, request))
|
||||
```
|
||||
|
||||
### 模板中创建变量
|
||||
|
||||
```django
|
||||
{% with firstname="Tobias" %}
|
||||
<h1>你好 {{ firstname }},你好吗?</h1>
|
||||
```
|
||||
|
||||
### 数组循环
|
||||
|
||||
```django
|
||||
<ul>
|
||||
{% for x in mymembers %}
|
||||
<li>{{ x.firstname }}</li>
|
||||
{% endfor %}
|
||||
</ul>
|

|
||||
<h1>欢迎女士们先生们</h1>
|
||||
{% endcomment %}
|
||||
```
|
||||
|
||||
注释允许您拥有应该被忽略的代码部分
|
||||
|
||||
### 双过滤值

```django
|
||||
<h1>你好 {{ firstname|first|upper }},你好吗?</h1>
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 过滤器标签
|
||||
|
||||
```django

|
||||
{% endfilter %}
|
||||
```
|
||||
|
||||
返回内容大写
|
||||
|
||||
### cycle
|
||||
<!--rehype:wrap-class=col-span-2 row-span-3-->
|
||||
|
||||
如果你想为每次循环使用新的背景颜色,你可以使用 `cycle` 标签来做到这一点
|
||||
|
||||
```django
|
||||
<ul>
|
||||
{% for x in members %}
|
||||
<li style='background-color:{% cycle 'lightblue' 'pink' 'yellow' 'coral' 'grey' %}'>
|
||||
{{ x.firstname }}
|
||||
</li>
|
||||
{% endfor %}
|
||||
</ul>
|
||||
```
|
||||
|
||||
将参数值保存在变量中,以便以后使用:
|
||||
|
||||
```django
|
||||
<ul>
|
||||
{% for x in members %}
|
||||
{% cycle 'lightblue' 'pink' 'yellow' 'coral' 'grey' as bgcolor silent %}
|
||||
<li style='background-color:{{ bgcolor }}'>
|
||||
{{ x.firstname }}
|
||||
</li>
|
||||
{% endfor %}
|
||||
</ul>
|
||||
```
|
||||
|
||||
你注意到 `silent` 关键字了吗? 确保添加这个,否则参数值将在输出中显示两次
|
||||
|
||||
```django
|
||||
<ul>
|
||||
{% for x in members %}
|
||||
{% cycle 'lightblue' 'pink' 'yellow' 'coral' 'grey' as bgcolor silent %}
|
||||
{% if forloop.counter == 3 %}
|
||||
{% resetcycle %}
|
||||
{% endif %}
|
||||
<li style='background-color:{{ bgcolor }}'>
|
||||
{{ x.firstname }}
|
||||
</li>
|
||||
{% endfor %}
|
||||
</ul>
|
||||
```
|
||||
|
||||
您可以使用 `{% resetcycle %}` 标签强制循环重新开始
|
||||
|
||||
### 每一行添加行号
|
||||
|
||||
```django
|
||||
{% filter upper|linenumbers %}Hello!
|
||||
my name is
|
||||
Emil.
|
||||
What is your name?{% endfilter %}
|
||||
```
|
||||
|
||||
返回内容`大写`并在每一行添加`行号`
|
||||
|
||||
### 导入模板
|
||||
|
||||
`footer.html`:
|
||||
|
||||
```django
|
||||

|
||||
```
|
||||
|
||||
`template.html`:
|
||||
|

|
||||
<p>此页面包含模板中的页脚</p>
|
||||
{% include 'footer.html' %}
|
||||
```
|
||||
|
||||
### 导入模板传入变量
|
||||
|
||||

|
||||
|
||||
```django
|

||||
```js
|
||||
class Circle extends Shape {
|
||||
```
|
||||
|
||||
#### 构造函数

|
||||
|
||||
|
||||
Promises
|
||||
--------
|
||||
|
||||
### 做出承诺
|
||||
|
||||
```js {1}
|
||||
new Promise((resolve, reject) => {
|
||||
if (ok) { resolve(result) }
|
||||
else { reject(error) }
|
||||
})
|
||||
```
|
||||
|
||||
用于异步编程。
|
||||
请参阅:[Promises](https://babeljs.io/learn-es2015/#promises)
|
||||
|
||||
### 使用 Promises
|
||||
|
||||
```js {2,3}
|
||||
promise
|
||||
.then((result) => { ··· })
|
||||
.catch((error) => { ··· })
|
||||
```
|
||||
|
||||
### 在 finally 中使用 Promise
|
||||
|
||||
```js {4}
|
||||
promise
|
||||
.then((result) => { ··· })
|
||||
.catch((error) => { ··· })
|
||||
.finally(() => {
|
||||
/* 独立于成功/错误的逻辑 */
|
||||
})
|
||||
```
|
||||
|
||||
当承诺被履行或被拒绝时,处理程序被调用
|
||||
|
||||
### Promise 函数
|
||||
|
||||
```js
|
||||
Promise.all(···)
|
||||
Promise.race(···)
|
||||
Promise.reject(···)
|
||||
Promise.resolve(···)
|
||||
```
|
||||
|
||||
### Async-await
|
||||
|
||||
```js {2,3}
|
||||
async function run () {
|
||||
const user = await getUser()
|
||||
const tweets = await getTweets(user)
|
||||
return [user, tweets]
|
||||
}
|
||||
```
|
||||
|
||||
`async` 函数是使用函数的另一种方式。
|
||||
请参阅:[异步函数](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function)
|
||||
|
||||
解构 Destructuring
|
||||
-------------
|
||||
|
||||
### 解构赋值
|
||||
|
||||
#### Arrays
|
||||
|
||||
```js {1}
|
||||
const [first, last] = ['Nikola', 'Tesla']
|
||||
```
|
||||
|
||||
#### Objects
|
||||
|
||||
```js {1}
|
||||
let {title, author} = {
|
||||
title: 'The Silkworm',
|
||||
author: 'R. Galbraith'
|
||||
}
|
||||
```
|
||||
|
||||
支持匹配数组和对象。
|
||||
请参阅:[解构](https://babeljs.io/learn-es2015/#destructuring)
|
||||
|
||||
### 默认值
|
||||
|
||||
```js
|
||||
const scores = [22, 33]
|
||||
const [math = 50, sci = 50, arts = 50] = scores
|
||||
```
|
||||
----
|
||||
```js
|
||||
// Result:
|
||||
// math === 22, sci === 33, arts === 50
|
||||
```
|
||||
|
||||
可以在解构数组或对象时分配默认值
|
||||
|
||||
### 函数参数
|
||||
|
||||
```js {1}
|
||||
function greet({ name, greeting }) {
|
||||
console.log(`${greeting}, ${name}!`)
|
||||
}
|
||||
```
|
||||
----
|
||||
```js
|
||||
greet({ name: 'Larry', greeting: 'Ahoy' })
|
||||
```
|
||||
|
||||
对象和数组的解构也可以在函数参数中完成
|
||||
|
||||
### 默认值
|
||||
|
||||
```js {1}
|
||||
function greet({ name = 'Rauno' } = {}) {
|
||||
console.log(`Hi ${name}!`);
|
||||
}
|
||||
```
|
||||
----
|
||||
```js
|
||||
greet() // Hi Rauno!
|
||||
greet({ name: 'Larry' }) // Hi Larry!
|
||||
```
|
||||
|
||||
### 重新分配键
|
||||
|
||||
```js {1}
|
||||
function printCoordinates({ left: x, top: y }) {
|
||||
console.log(`x: ${x}, y: ${y}`)
|
||||
}
|
||||
```
|
||||
----
|
||||
```js
|
||||
printCoordinates({ left: 25, top: 90 })
|
||||
```
|
||||
|
||||
此示例将 `x` 分配给 `left` 键的值
|
||||
|
||||
### 循环
|
||||
|
||||
```js {1}
|
||||
for (let {title, artist} of songs) {
|
||||
···
|
||||
}
|
||||
```
|
||||
|
||||
赋值表达式也在循环中工作
|
||||
|
||||
### 对象解构
|
||||
|
||||
```js {1}
|
||||
const { id, ...detail } = song;
|
||||
```
|
||||
|
||||
使用 `rest(...)` 运算符单独提取一些键和对象中的剩余键
|
||||
|
||||
扩展运算符 Spread
|
||||
------
|
||||
|
||||
### 对象扩展
|
||||
|
||||
#### 与对象扩展
|
||||
|
||||
```js {2}
|
||||
const options = {
|
||||
...defaults,
|
||||
visible: true
|
||||
}
|
||||
```
|
||||
|
||||
#### 没有对象扩展
|
||||
|
||||
```js
|
||||
const options = Object.assign(
|
||||
{}, defaults,
|
||||
{ visible: true })
|
||||
```
|
||||
|
||||
对象扩展运算符允许您从其他对象构建新对象。
|
||||
请参阅:[对象传播](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator)
|
||||
|
||||
### 数组扩展
|
||||
|
||||
#### 具有数组扩展
|
||||
|
||||
```js {2,3}
|
||||
const users = [
|
||||
...admins,
|
||||
...editors,
|
||||
'rstacruz'
|
||||
]
|
||||
```
|
||||
|
||||
#### 没有数组扩展
|
||||
|
||||
```js
|
||||
const users = admins
|
||||
.concat(editors)
|
||||
.concat([ 'rstacruz' ])
|
||||
```
|
||||
|
||||
扩展运算符允许您以相同的方式构建新数组。
|
||||

#### 隐式返回
|
||||
|
||||
```js {1,4,5,6}
|
||||
arr.map(n => n*2)
|
||||
// 没有花括号 = 隐式返回
|
||||
// 同: arr.map(function (n) { return n*2 })
|
||||
arr.map(n => ({
|
||||
result: n*2
|
||||
}))
|
||||
// 隐式返回对象需要在对象周围加上括号
|
||||
```
|
||||
|
||||
类似函数,但保留了 `this`。
|
||||
请参阅:[箭头函数](https://babeljs.io/learn-es2015/#arrows-and-lexical-this)

import { indent } from 'helpers'
|
||||
// 又名: const indent = require('···').indent
|
||||
```
|
||||
---
|
||||
```js
|
||||
import * as Helpers from 'helpers'
|
||||
// 又名: const Helpers = require('···')
|
||||
```
|
||||
---
|

|
||||
`import` 是新的 `require()`。
|
||||
请参阅:[Module imports](https://babeljs.io/learn-es2015/#modules)
|
||||
|
||||
### Exports 导出
|
||||
|
||||
```js
|
||||
export default function () { ··· }
|
||||
// 又名: module.exports.default = ···
|
||||
```
|
||||
----
|
||||
```js
|
||||
export function mymethod () { ··· }
|
||||
// 又名: module.exports.mymethod = ···
|
||||
```
|
||||
----
|
||||
```js
|
||||
export const pi = 3.14159
|
||||
// 又名: module.exports.pi = ···
|
||||
```
|
||||
|
||||
----
|
||||
|
||||
```js
|
||||
const firstName = 'Michael';
|
||||
const lastName = 'Jackson';
|
||||
const year = 1958;
|
||||
export { firstName, lastName, year };
|
||||
```
|
||||
|
||||
----
|
||||
|
||||
```js
|
||||
export * from "lib/math";
|
||||
```
|
||||
|
||||
`export` 是新的`module.exports`。
|
||||
请参阅:[Module exports](https://babeljs.io/learn-es2015/#modules)
|
||||
|
||||
### `as` 关键字重命名
|
||||
|
||||
```js {2,8,12-14}
|
||||
import {
|
||||
lastName as surname // 导入重命名
|
||||
} from './profile.js';
|
||||
|
||||
function v1() { ... }
|
||||
function v2() { ... }
|
||||
|
||||
export { v1 as default };
|
||||
// 等同于 export default v1;
|
||||
|
||||
export {
|
||||
v1 as streamV1, // 导出重命名
|
||||
v2 as streamV2, // 导出重命名
|
||||
v2 as streamLatestVersion // 导出重命名
|
||||
};
|
||||
```
|
||||
|
||||
### 动态加载模块
|
||||
|
||||
```js
|
||||
button.addEventListener('click', event => {
|
||||
import('./dialogBox.js')
|
||||
.then(dialogBox => {
|
||||
dialogBox.open();
|
||||
})
|
||||
.catch(error => {
|
||||
/* Error handling */
|
||||
})
|
||||
});
|
||||
```
|
||||
|
||||
[ES2020提案](https://github.com/tc39/proposal-dynamic-import) 引入 `import()` 函数
|
||||
|
||||
### import() 允许模块路径动态生成
|
||||
|
||||
```js
|
||||
const main = document.querySelector('main')
|
||||
|
||||
import(`./modules/${someVariable}.js`)
|
||||
.then(module => {
|
||||
module.loadPageInto(main);
|
||||
})
|
||||
.catch(err => {
|
||||
main.textContent = err.message;
|
||||
});
|
||||
```
|
||||
|
||||
### import.meta
|
||||
|
||||
[ES2020](https://github.com/tc39/proposal-import-meta) 为 `import` 命令添加了一个元属性 `import.meta`,返回当前模块的元信息
|
||||
|
||||
```js
|
||||
new URL('data.txt', import.meta.url)
|
||||
```
|
||||
|
||||
Node.js 环境中,`import.meta.url`返回的总是本地路径,即 `file:URL` 协议的字符串,比如 `file:///home/user/foo.js`
|
||||
|
||||
|
||||
Generators
|
||||
----------
|
||||
|
||||
### Generator 函数
|
||||
|
||||
```js
|
||||
function* idMaker () {
|
||||
let id = 0
|
||||
while (true) { yield id++ }
|
||||
}
|
||||
```
|
||||
---
|
||||
```js
|
||||
let gen = idMaker()
|
||||
gen.next().value // → 0
|
||||
gen.next().value // → 1
|
||||
gen.next().value // → 2
|
||||
```
|
||||
|
||||
情况很复杂。
|
||||
请参阅:[Generators](https://babeljs.io/learn-es2015/#generators)
|
||||
|
||||
### For..of + 迭代器(iterator)
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```js
|
||||
let fibonacci = {
|
||||
[Symbol.iterator]() {
|
||||
let pre = 0, cur = 1;
|
||||
return {
|
||||
next() {
|
||||
[pre, cur] = [cur, pre + cur];
|
||||
return { done: false, value: cur }
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
for (var n of fibonacci) {
|
||||
// 在 1000 处截断序列
|
||||
if (n > 1000) break;
|
||||
console.log(n);
|
||||
}
|
||||
```
|
||||
|
||||
用于迭代生成器和数组。
|
||||
请参阅:[For..of iteration](https://babeljs.io/learn-es2015/#iterators--forof)
|
||||
|
||||
### 与 Iterator 接口的关系
|
||||
|
||||
```js
|
||||
var gen = {};
|
||||
gen[Symbol.iterator] = function* () {
|
||||
yield 1;
|
||||
yield 2;
|
||||
yield 3;
|
||||
};
|
||||
|
||||
[...gen] // => [1, 2, 3]
|
||||
```
|
||||
|
||||
`Generator` 函数赋值给 `Symbol.iterator` 属性,从而使得 `gen` 对象具有了 `Iterator` 接口,可以被 `...` 运算符遍历了
|
||||
|
||||
|
||||
### Symbol.iterator 属性
|
||||
|
||||
```js
|
||||
function* gen() { /* some code */ }
|
||||
var g = gen();
|
||||
|
||||
g[Symbol.iterator]() === g // true
|
||||
```
|
||||
|
||||
`gen` 是一个 `Generator` 函数,调用它会生成一个遍历器对象`g`。它的 `Symbol.iterator` 属性,也是一个遍历器对象生成函数,执行后返回它自己

||||
|
||||
```js
|
||||
app.get('/user/:id', (req, res) => {
|
||||
res.send('user ' + req.params.id)
|
||||
})
|
||||
```
|
||||
|
||||
### Request
|
||||
|
||||
`req` 对象表示 `HTTP` 请求,并具有请求查询字符串、参数、正文、HTTP 标头等的属性
|
||||
|
||||
```js
|
||||
app.get('/user/:id', (req, res) => {
|
||||
res.send('user ' + req.params.id)
|
||||
})
|
||||
```
|
||||
|
||||
### res.end()
|
||||
|
||||
```js
|
||||
res.end()
|
||||
res.status(404).end()
|
||||
```
|
||||
|
||||
结束响应过程。这个方法其实来自 Node 核心,具体是 `http.ServerResponse` 的 `response.end()` 方法
|
||||
|
||||
### res.json([body])
|
||||
|
||||
```js
|
||||
res.json(null)
|
||||
res.json({ user: 'tobi' })
|
||||
res.status(500).json({ error: 'message' })
|
||||
```
|
||||
|
||||
### app.all
|
||||
|
||||
```js
|
||||
app.all('/secret', function (req, res, next) {
|
||||
console.log('访问秘密部分...')
|
||||
next() // 将控制权传递给下一个处理程序
|
||||
})
|
||||
```
|
||||
|
||||
### app.delete
|
||||
|
||||
```js
|
||||
app.delete('/', function (req, res) {
|
||||
res.send('DELETE request to homepage')
|
||||
})
|
||||
```
|
||||
|
||||
### app.disable(name)
|
||||
|
||||
```js
|
||||
app.disable('trust proxy')
|
||||
app.get('trust proxy')
|
||||
// => false
|
||||
```
|
||||
|
||||
### app.disabled(name)
|
||||
|
||||
```js
|
||||
app.disabled('trust proxy')
|
||||
// => true
|
||||
|
||||
app.enable('trust proxy')
|
||||
app.disabled('trust proxy')
|
||||
// => false
|
||||
```
|
||||
|
||||
### app.engine(ext, callback)
|
||||
|
||||
```js
|
||||
var engines = require('consolidate')
|
||||
|
||||
app.engine('haml', engines.haml)
|
||||
app.engine('html', engines.hogan)
|
||||
```
|
||||
|
||||
### app.listen([port[, host[, backlog]]][, callback])
|
||||
|
||||
```js
|
||||
var express = require('express')
|
||||
|
||||
var app = express()
|
||||
app.listen(3000)
|
||||
```
|
||||
|
||||
### 路由
|
||||
|
||||
```js
|
||||
const express = require('express')
|
||||
const app = express()
|
||||
|
||||
// 向主页发出 GET 请求时响应“hello world”
|
||||
app.get('/', (req, res) => {
|
||||
res.send('hello world')
|
||||
})
|
||||
```
|
||||
|
||||
```js
|
||||
// GET 方法路由
|
||||
app.get('/', (req, res) => {
|
||||
res.send('GET request to the homepage')
|
||||
})
|
||||
|
||||
// POST 方法路由
|
||||
app.post('/', (req, res) => {
|
||||
res.send('POST request to the homepage')
|
||||
})
|
||||
```
|
||||
|
||||
### 中间件
|
||||
|
||||
```js
|
||||
function logOriginalUrl (req, res, next) {
|
||||
console.log('ReqURL:', req.originalUrl)
|
||||
next()
|
||||
}
|
||||
|
||||
function logMethod (req, res, next) {
|
||||
console.log('Request Type:', req.method)
|
||||
next()
|
||||
}
|
||||
|
||||
const log = [logOriginalUrl, logMethod]
|
||||
|
||||
app.get('/user/:id', log,
|
||||
(req, res, next)=>{
|
||||
res.send('User Info')
|
||||
}
|
||||
)
|
||||
```
|
||||
|
||||
### 使用模版
|
||||
|
||||
```js
|
||||
app.set('view engine', 'pug')
|
||||
```
|
||||
|
||||
在 `views` 目录下创建一个名为 `index.pug` 的 `Pug` 模板文件,内容如下
|
||||
|
||||
```pug
|
||||
html
|
||||
head
|
||||
title= title
|
||||
body
|
||||
h1= message
|
||||
```
|
||||
|
||||
创建一个路由来渲染 `index.pug` 文件。如果未设置视图引擎属性,则必须指定视图文件的扩展名
|
||||
|
||||
```js
|
||||
app.get('/', (req, res) => {
|
||||
res.render('index', {
|
||||
title: 'Hey', message: 'Hello there!'
|
||||
})
|
||||
})
|
||||
```

|
||||
```
|
||||
|
||||
### 示例
|
||||
|
||||
mp4 转 avi:
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i input.mp4 output.avi
|
||||
```
|
||||
|
||||
webm 转 mp4:

|
||||
```
|
||||
|
||||
### 常用开关
|
||||
|
||||
```bash
|
||||
-codecs # 列出编解码器
|
||||
-c:v # 视频编解码器(-vcodec)-'copy'复制流
|
||||
-c:a # 音频编解码器(-acodec)
|
||||
-fs SIZE # 限制文件大小(字节)
|
||||
```
|
||||
|
||||
### 音频
|
||||
|
||||
```bash
|
||||
-aq QUALITY # 音频质量(特定于编解码器)
|
||||
-ar 44100 # 音频采样率 (Hz)
|
||||
-ac 1 # 音频通道(1=单声道,2=立体声)
|
||||
-an # 没有音频
|
||||
-vol N # 音量(256=正常)
|
||||
```
|
||||
|
||||
### 比特率
|
||||
|
||||
```bash
|
||||
-b:v 1M # 视频比特率(1M = 1Mbit/s)

||||
|
||||
```bash
|
||||
-aspect RATIO # 纵横比(4:3、16:9 或 1.25)
|
||||
-r RATE # 每秒帧率
|
||||
-s WIDTHxHEIGHT # 帧大小
|
||||
-vn # 没有视频
|

```
|
||||
|
||||
视频编辑
|
||||
---
|
||||
<!--rehype:body-class=cols-2-->
|
||||
|
||||
### 裁剪
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <input> -filter:v "crop=640:480:100:25" <output>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
通过从输入视频中复制偏移 `x=100px` `y=25px` 的相应窗口来创建 `640x480` 大小的输出视频
|
||||
|
||||
```bash
|
||||
# 裁剪到宽度 360,高度 640
|
||||
$ ffmpeg -i input.mov -filter:v 'crop=360:640:0:0' -codec:a copy output.mov
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
裁剪到宽度 360,高度 640,从坐标 (10, 20) 开始
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i input.mov -filter:v 'crop=360:640:10:20' -codec:a copy output.mov
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 缩放
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <输入> -vf scale=640:480 <输出>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 视频帧速率
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i input.avi -r 24 output.avi
|
||||
```
|
||||
|
||||
将输出文件的帧速率强制为 24 fps
|
||||
|
||||
```bash
|
||||
$ ffmpeg -r 1 -i input.m2v -r 24 output.avi
|
||||
```
|
||||
|
||||
将输入文件的帧速率(仅对原始格式有效)强制为 1 fps,将输出文件的帧速率强制为 24 fps
|
||||
|
||||
### 剪切视频部分
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <input> -ss 00:01:45 -t 00:02:35 -vcodec copy -acodec copy <output>
|
||||
$ ffmpeg -ss 00:00:30 -i orginalfile.mpg -t 00:00:05 -vcodec copy -acodec copy newfile.mpg
|
||||
# 从 4.5 秒开始的 5 秒长的视频
|
||||
$ ffmpeg -i in.mp4 -ss 4.5 -t 5 out.mp4
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### H265 2-pass 编码
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```bash
|
||||
$ ffmpeg -y -i <input> -c:v libx265 -b:v 2600k \
|
||||
-x265-params pass=1 \
|
||||
-an -f mp4 /dev/null && \
|
||||
ffmpeg -i <input> \
|
||||
-c:v libx265 -b:v 2600k \
|
||||
-x265-params pass=2 \
|
||||
-c:a aac -b:a 128k output.mp4
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
对于 `H265 2-pass` 编码,您需要组合 `2` 个 `ffmpeg` 调用
|
||||
|
||||
### 视频比特率设置
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i input.avi -b:v 64k -bufsize 64k output.avi
|
||||
```
|
||||
|
||||
将输出文件的视频比特率设置为 64 kbit/s
|
||||
|
||||
### 固定旋转
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <input> -c copy -metadata:s:v:0 rotate=90 <output>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
不要为旋转重新编码,而是简单地为旋转角度添加一个视频元数据字段
|
||||
|
||||
### 放慢视频速度
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i in.mp4 -filter:v "setpts=4.0*PTS" out.mp4
|
||||
```
|
||||
|
||||
使用过滤器减慢视频。 此示例将视频减慢四倍
|
||||
|
||||
### 缩放到特定宽度
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i in.mp4 -filter:v scale="538:trunc(ow/a/2)*2" -c:a copy out.mp4
|
||||
```
|
||||
|
||||
给定所需的视频宽度,例如 538 像素,您可以使用以下方法将视频调整为该宽度,同时保持宽高比
|
||||
|
||||
重新包装
|
||||
---
|
||||
|
||||
### 提取音频流
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i file.mp4 -vn -acodec copy output.aac
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
将`-vn`(无视频)与 `-acodec copy` 结合起来。请注意,输出文件扩展名必须与输入文件中的音频编解码器匹配,`-acodec copy` 才能工作。
|
||||
|
||||
### 创建缩略图
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
在 10 秒时创建一个缩略图
|
||||
|
||||
```bash
|
||||
$ ffmpeg -ss 10 -i <input file> -vframes 1 -vcodec png -an thumb.png
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
例如,要每 `n` 秒创建一次缩略图,请使用 `-vf fps=1/n`
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i <input file> -vf fps=1/60 thumbnails/thumb%03d.png
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 处理 id3 标签
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
提取
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i file.mp3 -f ffmetadata metadata.txt
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
设置
|
||||
|
||||
```bash
|
||||
$ ffmpeg -i file.mp3 -acodec copy -metadata title="<title>" -metadata artist="<artist>" -metadata album="<album>" out.mp3
|
||||
```
|
||||
<!--rehype:className=wrap-text -->

|
||||
|
||||
```bash
|
||||
$ ffmpeg -i file.aac -acodec mp3 -ar 44100 -ab 128000 output.mp3
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 切换容器(转换类型)
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
将容器从 `MKV` 更改为 `MP4`
|

```bash
|
||||
$ ffmpeg -i file.mkv -acodec copy -vcodec copy file.mp4
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
要将视频从 `.mov` 更改为 `.mp4`

```
|
||||
|
||||
把所有的改动都重新放回工作区,并**清空所有的 commit**,这样就可以重新提交第一个 `commit` 了

|
||||
$ git branch --merged master | grep -v '^\*\| master' | xargs -n 1 git branch -d
|
||||
```
|
||||
<!--rehype:className=wrap-text-->
|
||||
|
||||
### 关联远程分支
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```bash
|
||||
$ git branch -u origin/mybranch
|
||||
```
|
||||
|
||||
或者在 `push` 时加上 `-u` 参数
|
||||
|
||||
```bash
|
||||
git push origin/mybranch -u
|
||||
```
|
||||
|
||||
关联之后,`git branch -vv` 就可以展示关联的远程分支名了, 同时推送到远程仓库直接:`git push`,不需要指定远程仓库
|
||||
|
||||
### 查看远程分支和本地分支的对应关系
|
||||
|
||||
```bash
|
||||
$ git remote show origin
|
||||
```
|
||||
|
||||
### 展示当前分支的最近的 tag

|
||||
```
|
||||
<!--rehype:className=wrap-text-->
|
||||
|
||||
新建一个分支,分支内容就是上面 `git bundle create` 命令导出的内容
|
||||
|
||||
### 执行 rebase 之前自动 stash
|
||||
|
||||
```bash
|
||||
$ git rebase --autostash
|
||||

|
||||
|
||||
```bash
|
||||
$ git log --show-signature
|
||||
```
|
||||
|
||||
### 新建并切换到新分支上,同时这个分支没有任何 commit
|
||||
|
||||
```bash
|
||||
$ git checkout --orphan <branch-name>
|
||||
```
|
||||
|
||||
相当于保存修改,但是重写 commit 历史
|
||||
|
||||
### 展示任意分支某一文件的内容
|
||||
|
||||
```bash
|
||||
$ git show <branch-name>:<file-name>

### 配置 http 和 socks 代理
|
||||
<!--rehype:wrap-class=row-span-4-->
|
||||
|
||||
```bash
|
||||
# 查看代理
|
||||
$ git config --global http.proxy
|
||||
$ git config --global https.proxy
|
||||
$ git config --global socks.proxy
|
||||
|
||||
# 设置代理
|
||||
# 适用于 privoxy 将 socks 协议转为 http 协议的 http 端口
|
||||
$ git config --global http.proxy http://127.0.0.1:1080
|
||||
$ git config --global https.proxy http://127.0.0.1:1080
|
||||
$ git config --global socks.proxy 127.0.0.1:1080
|
||||
|
||||
# 取消代理
|
||||
$ git config --global --unset http.proxy
|
||||
$ git config --global --unset https.proxy
|
||||
$ git config --global --unset socks.proxy
|
||||
|
||||
# 只对 github.com 设置代理
|
||||
$ git config --global http.https://github.com.proxy socks5://127.0.0.1:1080
|
||||
$ git config --global https.https://github.com.proxy socks5://127.0.0.1:1080
|
||||
|
||||
# 取消 github.com 代理
|
||||
$ git config --global --unset http.https://github.com.proxy
|
||||
$ git config --global --unset https.https://github.com.proxy
|
||||
```
|
||||
|
||||
|
||||
### clone 最新一次提交
|
||||
|
||||
```bash
|
||||
$ git clone --depth=1 https://github.com/user/repo.git
|
||||
```
|
||||
|
||||
只会 `clone` 最近一次提交,将减少 `clone` 时间
|
||||
|
||||
### 忽略某个文件的改动
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
关闭 track 指定文件的改动,也就是 Git 将不会在记录这个文件的改动
|
||||
|
||||
```bash
|
||||
git update-index --assume-unchanged path/to/file
|
||||
```
|
||||
<!--rehype:className=wrap-text-->
|
||||
|
||||
恢复 track 指定文件的改动
|
||||
|
||||
```bash
|
||||
git update-index --no-assume-unchanged path/to/file
|
||||
```
|
||||
<!--rehype:className=wrap-text-->
|
||||
|
||||
### 以最后提交的顺序列出所有 Git 分支
|
||||
|
||||
```bash
|
||||
git for-each-ref --sort=-committerdate --format='%(refname:short)' refs/heads
|
||||
```
|
||||
|
||||
最新的放在最上面
|
||||
|
||||
### 在 commit log 中查找相关内容
|
||||
|
||||
```bash
|
||||
git log --all --grep='<given-text>'
|
||||
```
|
||||
|
||||
通过 grep 查找,given-text: 所需要查找的字段
|
||||
|
||||
### 把暂存区的指定 file 放到工作区中
|
||||
|
||||
```bash
|
||||
git reset <file-name>
|
||||
```
|
||||
|
||||
不添加参数,默认是 `-mixed`
|
||||
|
||||
### 配置 SSH 协议代理
|
||||
|
||||
```shell
|
||||
# 对于使用 git@ 协议的,可以配置 socks5 代理
|
||||
# macOS 系统编辑 ~/.ssh/config 文件,添加这几行,设置 github 代理
|
||||
Host github.com
|
||||
ProxyCommand nc -X 5 -x 127.0.0.1:1080 %h %p
|
||||
```

Github Actions 备忘清单
|
||||
====
|
||||
|
||||
本备忘单总结了 [Github Actions](https://github.com/actions) 常用的配置说明,以供快速参考。
|
||||
|
||||
入门
|
||||
---
|
||||
|
||||
### 介绍
|
||||
|
||||
GitHub [Actions](https://github.com/actions) 的仓库中自动化、自定义和执行软件开发工作流程,有四个基本的概念,如下:
|
||||
|
||||
:- | :-
|
||||
:- | :-
|
||||
`workflow` _(工作流程)_ | 持续集成一次运行的过程,就是一个 `workflow`
|
||||
`job` _(任务)_ | 一个 `workflow` 由一个或多个 `jobs` 构成,含义是一次持续集成的运行,可以完成多个任务
|
||||
`step` _(步骤)_ | 每个 `job` 由多个 `step` 构成,一步步完成
|
||||
`action` _(动作)_ | 每个 `step` 可以依次执行一个或多个命令(`action`)
|
||||
<!--rehype:className=style-list-arrow-->
|
||||
|
||||
---
|
||||
|
||||
- 采用 [YAML](./yaml.md) 格式定义配置文件
|
||||
- 存放在代码仓库的 `.github/workflows` 目录中
|
||||
- 后缀名统一为 `.yml`,比如 `ci.yml`
|
||||
- 一个库可以有多个 `workflow` 文件
|
||||
- 根据配置事件自动运行配置文件
|
||||
<!--rehype:className=style-round-->

||||
- uses: actions/checkout@v3
|
||||
- uses: actions/setup-node@v3
|
||||
with:
|
||||
node-version: 16
|
||||
|
||||
- run: npm install
|
||||
- run: npm run build
|
||||
```
|
||||
|
||||
存放到 `.github/workflows` 目录中,命名为 `ci.yml`,当 `push` 代码到仓库 `main` 分支中,该配置自动运行配置。
|
||||
|
||||
### 指定触发
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
`push` 事件触发 `workflow`
|
||||
|
||||
```yaml
|
||||
on: push
|
||||
```
|
||||
|
||||
`push` 事件或 `pull_request` 事件都可以触发 `workflow`
|
||||
|
||||
```yaml
|
||||
on: [push, pull_request]
|
||||
```
|
||||
|
||||
只有在 `main` 分支 `push` 事件触发 `workflow`
|
||||
|
||||
```yaml {2}
|
||||
on:
|
||||
push:
|
||||
branches:
|
||||
- main
|
||||
```
|
||||
|
||||
`push` 事件触发 `workflow`,`docs` 目录下的更改 `push` 事件不触发 `workflow`
|
||||
|
||||
```yaml {2,4}
|
||||
on:
|
||||
push:
|
||||
paths-ignore:
|
||||
- 'docs/**'
|
||||
```
|
||||
|
||||
push 事件触发 workflow,包括 sub-project 目录或其子目录中的文件触发 workflow,除非该文件在 sub-project/docs 目录中,不触发 workflow
|
||||
|
||||
```yaml
|
||||
on:
|
||||
push:
|
||||
paths:
|
||||
- 'sub-project/**'
|
||||
- '!sub-project/docs/**'
|
||||
```
|
||||
|
||||
版本发布为 `published` 时运行工作流程。
|
||||
|
||||
```yml
|
||||
on:
|
||||
release:
|
||||
types: [published]
|
||||
```
|
||||
|
||||
### 多项任务
|
||||
|
||||
```yml
|
||||
jobs:
|
||||
my_first_job: # 第一个任务
|
||||
name: My first job
|
||||
|
||||
my_second_job: # 第二个任务
|
||||
name: My second job
|
||||
```
|
||||
|
||||
通过 jobs `(jobs.<job_id>.name)`字段,配置一项或多项需要执行的任务
|
||||
|
||||
### 多项任务依赖关系
|
||||
|
||||
通过 needs `(jobs.<job_id>.needs)`字段,指定当前任务的依赖关系
|
||||
|
||||
```yml
|
||||
jobs:
|
||||
job1:
|
||||
job2:
|
||||
needs: job1
|
||||
job3:
|
||||
needs: [job1, job2]
|
||||
```
|
||||
|
||||
上面配置中,`job1` 必须先于 `job2` 完成,而 `job3` 等待 `job1` 和 `job2` 的完成才能运行。因此,这个 `workflow` 的运行顺序依次为:`job1`、`job2`、`job3`
|
||||
|
||||
### 多项任务传递参数
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
```yml {2,5,9,11,15}
|
||||
jobs:
|
||||
job1:
|
||||
runs-on: ubuntu-latest
|
||||
# 将步骤输出映射到作业输出
|
||||
outputs:
|
||||
output1: ${{ steps.step1.outputs.test }}
|
||||
output2: ${{ steps.step2.outputs.test }}
|
||||
steps:
|
||||
- id: step1
|
||||
run: echo "::set-output name=test::hello"
|
||||
- id: step2
|
||||
run: echo "::set-output name=test::world"
|
||||
job2:
|
||||
runs-on: ubuntu-latest
|
||||
needs: job1
|
||||
steps:
|
||||
- run: echo ${{needs.job1.outputs.output1}} ${{needs.job1.outputs.output2}}
|
||||
```
|
||||
|
||||
### 指定每项任务的虚拟机环境
|
||||
|
||||
```yml
|
||||
runs-on: ubuntu-latest
|
||||
```
|
||||
|
||||
指定运行所需要的虚拟机环境,⚠️ 它是必填字段
|
||||
|
||||
```yml {3}
|
||||
jobs:
|
||||
build: # 任务名称
|
||||
runs-on: ubuntu-latest # 虚拟机环境配置
|
||||
```
|
||||
|
||||

另见: [选择 GitHub 托管的运行器](https://docs.github.com/cn/actions/using-workflows/workflow-syntax-for-github-actions#选择-github-托管的运行器)
|
||||
|
||||
### 指定每项任务的步骤
|
||||
|
||||
每个步骤都可以指定以下三个字段
|
||||
|
||||
```shell
|
||||
jobs.<job_id>.steps.name # 步骤名称
|
||||
# 该步骤运行的命令或者 action
|
||||
jobs.<job_id>.steps.run
|
||||
# 该步骤所需的环境变量
|
||||
jobs.<job_id>.steps.env
|
||||
```
|
||||
|
||||
`steps` 字段指定每个 `Job` 的运行步骤,可以包含一个或多个步骤(`steps`)
|
||||
|
||||
```yml {4}
|
||||
jobs:
|
||||
build:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
- uses: actions/checkout@v3
|
||||
- uses: actions/setup-node@v3
|
||||
with:
|
||||
node-version: 16
|
||||
|
||||
- run: npm install
|
||||
- run: npm run build
|
||||
```
|
||||
|
||||
### 环境变量
|
||||
|
||||
```shell
|
||||
jobs.<job_id>.environment
|
||||
```
|
||||
使用单一环境名称的示例
|
||||
|
||||
```yml
|
||||
environment: staging_environment
|
||||
```
|
||||
|
||||
使用环境名称和 URL 的示例
|
||||
|
||||
```yml
|
||||
environment:
|
||||
name: production_environment
|
||||
url: https://github.com
|
||||
```
|
||||
|
||||
#### 自定义环境变量
|
||||
|
||||
`GitHub` 会保留 `GITHUB_` 环境变量前缀供 `GitHub` 内部使用。设置有 `GITHUB_` 前缀的环境变量或密码将导致错误。
|
||||
|
||||
```yml
|
||||
- name: 测试 nodejs 获取环境变量
|
||||
env:
|
||||
API_TOKEN: ${{ secrets.API_TOKEN }}
|
||||
```
|
||||
|
||||
在 `https://github.com/<用户名>/<项目名称>/settings/secrets` 中添加 `secrets` `API_TOKEN`,在工作流中设置环境变量 [`API_TOKEN`](https://github.com/jaywcjlove/github-actions/blob/799b232fca3d9df0272eaa12610f9ebfca51b288/.github/workflows/ci.yml#L46)
|
||||
|
||||
### 表达式
|
||||
|
||||
在 `if` 条件下使用表达式时,可以省略表达式语法 (`${{ }}`),因为 GitHub 会自动将 `if` 条件作为表达式求值
|
||||
|
||||
```yml {3}
|
||||
steps:
|
||||
- uses: actions/hello-world-action@v1.1
|
||||
if: github.repository == 'uiw/uiw-repo'
|
||||
# if: ${{ <expression> }}
|
||||
```
|
||||
|
||||
设置环境变量的示例
|
||||
|
||||
|
||||
```yml
|
||||
env:
|
||||
MY_ENV_VAR: ${{ <expression> }}
|
||||
```
|
||||
|
||||
#### 操作符
|
||||
|
||||
- `( )` _(逻辑分组)_
|
||||
- `[ ]` _(指数)_
|
||||
- `.` _(属性取消引用)_
|
||||
- `!` _(不是)_
|
||||
- `<` _(少于)_
|
||||
- `<=` _(小于或等于)_
|
||||
- `>` _(比...更棒)_
|
||||
- `>=` _(大于或等于)_
|
||||
- `==` _(平等的)_
|
||||
- `!=` _(不相等)_
|
||||
- `&&` _(和)_
|
||||
- `||` _(或者)_

# git -c "http.extraheader=$auth_header" -c protocol.version=2 submodule update --init --remote --force --recursive --checkout ant.design
|
||||
```
|
||||
|
||||
### 步骤依赖作业
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
使用 `jobs.<job_id>.needs` 识别在此作业运行之前必须成功完成的任何作业。它可以是一个字符串,也可以是字符串数组。 如果某个作业失败,则所有需要它的作业都会被跳过,除非这些作业使用让该作业继续的条件表达式。
|
||||
|
||||
```yml
|
||||
jobs:
|
||||
job1:
|
||||
job2:
|
||||
needs: job1
|
||||
job3:
|
||||
needs: [job1, job2]
|
||||
```
|
||||
|
||||
在此示例中,`job1` 必须在 `job2` 开始之前成功完成,而 `job3` 要等待 `job1` 和 `job2` 完成。此示例中的作业按顺序运行:
|
||||
|
||||
```
|
||||
❶ job1
|
||||
❷ job2
|
||||
❸ job3
|
||||
```
|
||||
|
||||
配置如下
|
||||
|
||||
```yml
|
||||
jobs:
|
||||
job1:
|
||||
job2:
|
||||
needs: job1
|
||||
job3:
|
||||
if: ${{ always() }}
|
||||
needs: [job1, job2]
|
||||
```
|
||||
|
||||
在此示例中,`job3` 使用 `always()` 条件表达式,因此它始终在 `job1` 和 `job2` 完成后运行,不管它们是否成功。
|
||||
|
||||
### 同步 Gitee
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
```yml
|
||||
- name: Sync to Gitee
|
||||
run: |
|
||||
mirror() {
|
||||
git clone "https://github.com/$1/$2"
|
||||
cd "$2"
|
||||
git remote add gitee "https://jaywcjlove:${{ secrets.GITEE_TOKEN }}@gitee.com/uiw/$2"
|
||||
git remote set-head origin -d
|
||||
git push gitee --prune +refs/remotes/origin/*:refs/heads/* +refs/tags/*:refs/tags/*
|
||||
cd ..
|
||||
}
|
||||
mirror uiwjs uiw
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 提交 NPM 包
|
||||
|
||||
```yml
|
||||
- run: npm publish --access public
|
||||
env:
|
||||
NODE_AUTH_TOKEN: ${{secrets.NPM_TOKEN}}
|
||||
```
|
||||
|
||||
获取 `NPM_TOKEN`,可以通过 [npm](https://www.npmjs.com/settings/wcjiang/tokens) 账号创建 `token`
|
||||
|
||||
```shell
|
||||
npm token list [--json|--parseable] # 查看
|
||||
npm token create [--read-only] [--cidr=1.1.1.1/24,2.2.2.2/16] # 创建
|
||||
npm token revoke <id|token> # 撤销
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
可以使用 [JS-DevTools/npm-publish](https://github.com/JS-DevTools/npm-publish) 提交
|
||||
|
||||
```yml
|
||||
- name: 📦 @province-city-china/data
|
||||
uses: JS-DevTools/npm-publish@v1
|
||||
with:
|
||||
token: ${{ secrets.NPM_TOKEN }}
|
||||
package: packages/data/package.json
|
||||
```
|
||||
|
||||
它有个好处,检测 `package.json` 中版本号是否发生变更,来决定是否提交版本,不会引发流程错误。
|
||||
|
||||
### 步骤作业文件共享
|
||||
|
||||
Artifacts 是 GitHub Actions 为您提供持久文件并在运行完成后使用它们或在作业(文档)之间共享的一种方式。
|
||||
|
||||
要创建工件并使用它,您将需要不同的操作:上传和下载。
|
||||
要上传文件或目录,您只需像这样使用它:
|
||||
|
||||
```yml
|
||||
steps:
|
||||
- uses: actions/checkout@v2
|
||||
- run: mkdir -p path/to/artifact
|
||||
- run: echo hello > path/to/artifact/a.txt
|
||||
- uses: actions/upload-artifact@v2
|
||||
with:
|
||||
name: my-artifact
|
||||
path: path/to/artifact/a.txt
|
||||
```
|
||||
|
||||
然后下载 `artifact` 以使用它:
|
||||
|
||||
```yml
|
||||
steps:
|
||||
- uses: actions/checkout@v2
|
||||
- uses: actions/download-artifact@v2
|
||||
with:
|
||||
name: my-artifact
|
||||
```
|
||||
|
||||
### Node.js
|
||||
|
||||
```yml
|
||||
- name: Setup Node
|
||||
uses: actions/setup-node@v2
|
||||
with:
|
||||
node-version: 14
|
||||
```
|
||||
|
||||
使用[矩阵策略](https://docs.github.com/cn/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstrategy) 在 nodejs 不同版本中运行
|
||||
|
||||
```yml
|
||||
strategy:
|
||||
matrix:
|
||||
node-version: [10.x, 12.x, 14.x]
|
||||
|
||||
steps:
|
||||
- uses: actions/checkout@v2
|
||||
- name: 使用 Node ${{ matrix.node-version }}
|
||||
uses: actions/setup-node@v1
|
||||
with:
|
||||
node-version: ${{ matrix.node-version }}
|
||||
- run: npm ci
|
||||
- run: npm run build --if-present
|
||||
- run: npm test
|
||||
```
|
||||
|
||||
### 提交 docker 镜像
|
||||
<!--rehype:wrap-class=col-span-2 row-span-2-->
|
||||
|
||||
```yml
|
||||
# https://www.basefactor.com/github-actions-docker
|
||||
- name: Docker login
|
||||
run: docker login -u ${{ secrets.DOCKER_USER }} -p ${{ secrets.DOCKER_PASSWORD }}
|
||||
|
||||
- name: Build ant.design image
|
||||
run: |
|
||||
cd ./ant\.design
|
||||
docker build -t ant.design .
|
||||
- name: Tags & Push docs
|
||||
run: |
|
||||
# Strip git ref prefix from version
|
||||
VERSION=$(echo "${{ github.ref }}" | sed -e 's,.*/\(.*\),\1,')
|
||||
|
||||
# Strip "v" prefix from tag name
|
||||
[[ "${{ github.ref }}" == "refs/tags/"* ]] && VERSION=$(echo $VERSION | sed -e 's/^v//')
|
||||
|
||||
docker tag ant.design ${{ secrets.DOCKER_USER }}/ant.design:$VERSION
|
||||
docker tag ant.design ${{ secrets.DOCKER_USER }}/ant.design:latest
|
||||
docker push ${{ secrets.DOCKER_USER }}/ant.design:$VERSION
|
||||
docker push ${{ secrets.DOCKER_USER }}/ant.design:latest
|
||||
```
|
||||
|
||||
### 创建一个 tag
|
||||
|
||||
```yml
|
||||
- name: Create Tag
|
||||
id: create_tag
|
||||
uses: jaywcjlove/create-tag-action@main
|
||||
with:
|
||||
package-path: ./package.json
|
||||
```
|
||||
|
||||
根据 `package-path` 指定的 `package.json` 检测 `version` 是否发生变化来创建 `tag`
|
||||
|
||||
### 生成 git 提交日志
|
||||
|
||||
```yml
|
||||
- name: Generate Changelog
|
||||
id: changelog
|
||||
uses: jaywcjlove/changelog-generator@main
|
||||
with:
|
||||
filter-author: (小弟调调™)
|
||||
|
||||
- name: Get the changelog
|
||||
run: echo "${{ steps.changelog.outputs.changelog }}"
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 提交到 GitHub docker 镜像仓库
|
||||
<!--rehype:wrap-class=col-span-3-->
|
||||
|
||||
```yml
|
||||
- name: '登录到 GitHub 注册表'
|
||||
run: echo ${{ github.token }} | docker login ghcr.io -u ${{ github.actor }} --password-stdin
|
||||
|
||||
- name: '编译 docker image'
|
||||
run: docker build -t ghcr.io/jaywcjlove/reference:latest .
|
||||
|
||||
- name: '推送到 GitHub 注册表中'
|
||||
run: docker push ghcr.io/jaywcjlove/reference:latest
|
||||
|
||||
- name: '标记 docker 镜像并发布到 GitHub 注册表'
|
||||
if: steps.create_tag.outputs.successful
|
||||
run: |
|
||||
echo "version: v${{ steps.changelog.outputs.version }}"
|
||||
docker tag ghcr.io/jaywcjlove/reference:latest ghcr.io/jaywcjlove/reference:${{steps.changelog.outputs.version}}
|
||||
docker push ghcr.io/jaywcjlove/reference:${{steps.changelog.outputs.version}}
|
||||
```
|
||||
|
||||
### 提交 commit 到 master 分支
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
```yml
|
||||
- name: 生成一个文件,并将它提交到 master 分支
|
||||
run: |
|
||||
# Strip git ref prefix from version
|
||||
VERSION=$(echo "${{ github.ref }}" | sed -e 's,.*/\(.*\),\1,')
|
||||
COMMIT=released-${VERSION}
|
||||
# Strip "v" prefix from tag name
|
||||
[[ "${{ github.ref }}" == "refs/tags/"* ]] && VERSION=$(echo $VERSION | sed -e 's/^v//')
|
||||
echo "输出版本号:$VERSION"
|
||||
# 将版本输出到当前 VERSION 文件中
|
||||
echo "$VERSION" > VERSION
|
||||
echo "1. 输出Commit:$commit"
|
||||
echo "2. Released $VERSION"
|
||||
git fetch
|
||||
git config --local user.email "action@github.com"
|
||||
git config --local user.name "GitHub Action"
|
||||
git add .
|
||||
git commit -am $COMMIT
|
||||
git branch -av
|
||||
git pull origin master
|
||||
|
||||
- name: 将上面的提交 push 到 master 分支
|
||||
uses: ad-m/github-push-action@master
|
||||
with:
|
||||
github_token: ${{ secrets.GITHUB_TOKEN }}
|
||||
```
|
||||
|
||||
### 作业之间共享数据
|
||||
|
||||
创建一个文件,然后将其作为构件上传
|
||||
|
||||
```yml {11}
|
||||
jobs:
|
||||
example-job:
|
||||
name: Save output
|
||||
steps:
|
||||
- shell: bash
|
||||
run: |
|
||||
expr 1 + 1 > output.log
|
||||
- name: Upload output file
|
||||
uses: actions/upload-artifact@v3
|
||||
with:
|
||||
name: output-log-file
|
||||
path: output.log
|
||||
```
|
||||
|
||||
可以下载名为 `output-log-file` 的工件
|
||||
|
||||
```yml {7}
|
||||
jobs:
|
||||
example-job:
|
||||
steps:
|
||||
- name: Download a single artifact
|
||||
uses: actions/download-artifact@v3
|
||||
with:
|
||||
name: output-log-file
|
||||
```
|
||||
|
||||
### 指定运行命令的工作目录
|
||||
|
||||
```yml {3}
|
||||
- name: Clean temp directory
|
||||
run: rm -rf *
|
||||
working-directory: ./temp
|
||||
```
|
||||
|
||||
使用 `working-directory` 关键字,您可以指定运行命令的工作目录(`./temp`)
|
||||
|
||||
#### defaults.run
|
||||
|
||||
```yml {4,5,7}
|
||||
jobs:
|
||||
job1:
|
||||
runs-on: ubuntu-latest
|
||||
defaults:
|
||||
run:
|
||||
shell: bash
|
||||
working-directory: scripts
|
||||
```
|
||||
|
||||
作业中的所有 `run` 步骤提供默认的 `shell` 和 `working-directory`
|
||||
|
||||
### jobs.<job_id>.steps[*].shell
|
||||
|
||||
使用 `bash` 运行脚本
|
||||
|
||||
```yml {4}
|
||||
steps:
|
||||
- name: Display the path
|
||||
run: echo $PATH
|
||||
shell: bash
|
||||
```
|
||||
|
||||
运行 `python` 脚本
|
||||
|
||||
```yml {6}
|
||||
steps:
|
||||
- name: Display the path
|
||||
run: |
|
||||
import os
|
||||
print(os.environ['PATH'])
|
||||
shell: python
|
||||
```
|
||||
|
||||
您可以使用 `shell` 关键字覆盖运行器操作系统中的默认 `shell` 设置
|
||||
|
||||

||||
|
||||
该备忘单提供了帮助您使用 [Golang](https://golang.org) 的基本语法和方法。
|
||||
|
||||
入门
|
||||
--------
|
||||
|
||||
### hello.go
|
||||
|
||||
```go
|
||||
package main
|
||||
import "fmt"
|
||||
func main() {
|
||||
fmt.Println("Hello, world!")
|
||||
}
|
||||
```
|
||||
|
||||
直接运行
|
||||
|
||||
```shell
|
||||
$ go run hello.go
|
||||
Hello, world!
|
||||
```

### 常量(Constants)
|
||||
|
||||
```go
|

const s string = "constant"
|
||||
const Phi = 1.618
|
||||
const n = 500000000
|

const d = 3e20 / n
|
||||
fmt.Println(d)
|
||||
```
|
||||
|
||||
### 类型转换
|
||||
|
||||
```go
|
||||
i := 90
|
||||
f := float64(i)
|
||||
u := uint(i)
|
||||
// 将等于字符Z
|
||||
s := string(i)
|
||||
```
|
||||
|
||||
#### 如何获取int字符串?
|
||||
|
||||
```go
|
||||
i := 90
|
||||
// 需要导入“strconv”
|
||||
s := strconv.Itoa(i)
|
||||
fmt.Println(s) // Outputs: 90

Golang 结构和映射
|
||||
--------
|
||||
|
||||
### 定义
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```go
|
||||
package main
|
||||
import (
|
||||
"fmt"
|
||||
)
|
||||
type Vertex struct {
|
||||
X int
|
||||
Y int
|
||||
}
|
||||
func main() {
|
||||
v := Vertex{1, 2}
|
||||
v.X = 4
|
||||
fmt.Println(v.X, v.Y) // => 4 2
|
||||
}
|
||||
```
|
||||
|
||||
参见:[结构(Structs)](https://tour.golang.org/moretypes/2)
|
||||
|
||||
### 字面量
|
||||
|
||||
```go
|
||||
v := Vertex{X: 1, Y: 2}
|
||||
// Field names can be omitted
|
||||
v := Vertex{1, 2}
|
||||
// Y is implicit
|
||||
v := Vertex{X: 1}
|
||||
```
|
||||
|
||||
您还可以输入字段名
|
||||
|
||||
### 映射
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```go
|
||||
m := make(map[string]int)
|
||||
m["k1"] = 7
|
||||
m["k2"] = 13
|
||||
fmt.Println(m) // => map[k1:7 k2:13]
|
||||
v1 := m["k1"]
|
||||
fmt.Println(v1) // => 7
|
||||
fmt.Println(len(m)) // => 2
|
||||
delete(m, "k2")
|
||||
fmt.Println(m) // => map[k1:7]
|
||||
_, prs := m["k2"]
|
||||
fmt.Println(prs) // => false
|
||||
n := map[string]int{"foo": 1, "bar": 2}
|
||||
fmt.Println(n) // => map[bar:2 foo:1]
|
||||
```
|
||||
|
||||
### 指向结构的指针
|
||||
|
||||
```go
|
||||
v := &Vertex{1, 2}
|
||||
v.X = 2
|
||||
```
|
||||
|
||||
Doing `v.X` is the same as doing `(*v).X`, when `v` is a pointer.

||||
|
||||
```go
|
||||
func main() {
|
||||
var d = int64(0)
|
||||
defer func(d *int64) {
|
||||
fmt.Printf("& %v Unix Sec\n", *d)
|
||||
}(&d)
|
||||
fmt.Print("Done ")
|
||||
d = time.Now().Unix()
|
||||
}
|
||||
```
|
||||
|
||||
`defer` 函数使用当前值`d`,除非我们使用指针在 `main` 末尾获取最终值
|
||||
|
||||
### Defer
|
||||
|
||||
```go
|
||||
func main() {
|
||||
defer fmt.Println("Done")
|
||||
fmt.Println("Working...")
|
||||
}
|
||||
```

}
|
||||
func (r Rectangle) Perimeter() float64 {
|
||||
return 2 * (r.Length + r.Width)
|
||||
}
|

`F1`, `h`, `?` | 转到帮助屏幕
|
||||
`F10`, `q` | 退出
|
||||
`Space` | 标记或取消标记进程
|
||||
`U` | 取消标记所有进程(删除所有使用 Space 键添加的标记)
|
||||
`s` | 跟踪进程系统调用:如果安装了 `strace(1)`,按下此键会将其附加到当前选定的进程,呈现进程发出的系统调用的实时更新
|
||||
`l` | 显示进程打开的文件:如果安装了 `lsof(1)`,按下该键将显示进程打开的文件描述符列表
|
||||
`F2`, `S` | 转到设置屏幕,您可以在其中配置屏幕顶部显示的仪表,设置各种显示选项,在配色方案中进行选择,并选择显示的列,以何种顺序显示
|
||||
`F3`, `/` | 逐步搜索所有显示进程的命令行。当前选定(突出显示)的命令将在您键入时更新。在搜索模式下,按 `F3` 将循环匹配出现的事件
|
||||
`F4`, `\` | 增量进程过滤:输入部分进程命令行,仅显示名称匹配的进程。要取消过滤,请再次输入过滤选项并按 `Esc`
|
||||
`F5`, `t` | 树视图:按父级组织进程,并将它们之间的关系布局为树。切换键将在树和您之前选择的排序视图之间切换。选择排序视图将退出树视图
|
||||
`F6` | 在排序视图上,选择一个字段进行排序,也可以通过 < 和 > 访问。当前排序字段由标题中的突出显示。在树视图中,展开或折叠当前子树。树节点中的“+”指示符表示它已折叠
|
||||

|
||||
`F8`, `[` | 降低选定进程的优先级(添加到“nice”值)
|
||||
`F9`, `k` | “杀死”进程:向一个或一组进程发送一个在菜单中选择的信号。如果进程被标记,则将信号发送到所有标记的进程。如果没有标记,则发送到当前选定的进程
|
||||
`+`, `-` | 在树视图模式下,展开或折叠子树。
|
||||
`a` | (在多 CPU 机器上)设置 CPU 亲和性:标记允许进程使用的 CPU
|
||||
`u` | 仅显示指定用户拥有的进程
|
||||
`F` | “跟随”进程:如果排序顺序导致当前选定的进程在列表中移动,则使选择栏跟随它。这对于监控进程很有用:这样,您可以使进程始终在屏幕上可见。使用移动键时,“跟随”失效。
|
||||
`p` | 在适用的情况下显示运行程序的完整路径(这是一个切换键)
|
||||
`Ctrl-L` | 刷新:重绘屏幕并重新计算数值
|
||||
`Numbers` | PID搜索:输入进程ID,选择突出显示将移至它

INI 备忘清单
|
||||
====
|
||||
|
||||
这是理解和编写 INI 格式配置文件的快速参考备忘单,此清单包含配置的内容,结构和语法等内容。
|
||||
|
||||
入门
|
||||
------
|
||||
|
||||
### 介绍
|
||||
|
||||
INI 是一种固定标准格式的配置文件,INI配置方法来自 MS-DOS 操作系统
|
||||
|
||||
```ini
|
||||
; 这里是注释
|
||||
[owner]
|
||||
name=John Doe
|
||||
organization=Acme Products
|
||||
|
||||
[database]
|
||||
; 这里是注释
|
||||
server=192.0.2.42
|
||||
port=143
|
||||
file="acme payroll.dat"
|
||||
```
|
||||
|
||||
现在已成为许多配置的非正式标准,其它操作系统可能使用 `.conf` 或 `.cfg` 作为后缀
|
||||
|
||||
### 稳定的特性
|
||||
|
||||
- 基本元素是键或属性
|
||||
- 每个键由`名称`和`值`构成,等号 (=) 分隔
|
||||
- `键名称`显示在等号的`左侧`
|
||||
- `等号`和`分号`是`保留`字符
|
||||
<!--rehype:className=style-round-->
|
||||
|
||||
```ini
|
||||
name = value
|
||||
```
|
||||
|
||||
与下面👇 JSON 大致相同
|
||||
|
||||
```js
|
||||
{
|
||||
"name": "value"
|
||||
}
|
||||
```
|
||||
|
||||
### 注释
|
||||
|
||||
注释 (`;`)
|
||||
|
||||
```ini
|
||||
; 这里是注释文本,将被忽略
|
||||
```
|
||||
|
||||
注释 (`#`)
|
||||
|
||||
```ini
|
||||
# 这里是注释文本,⚠️ 部分编译器支持
|
||||
```
|
||||
|
||||
一行之后的注释 (`;`,`#`) _(不标准)_
|
||||
|
||||
```ini
|
||||
var = a ; 这是一个内联注释
|
||||
foo = bar # 这是另一个内联注释
|
||||
```
|
||||
|
||||
在某些情况下注释必须单独出现在行上
|
||||
|
||||
### 部分(Sections)
|
||||
|
||||
- 名称单独出现在一行中
|
||||
- 名称在方括号 `[` 和 `]` 中
|
||||
- 没有明确的 `section 结束` 分隔符
|
||||
- 在下一个 `section` 声明处或文件末尾处结束
|
||||
- 部分和属性名称不区分大小写
|
||||
<!--rehype:className=style-round-->
|
||||
|
||||
```ini
|
||||
[section]
|
||||
key1 = a
|
||||
key2 = b
|
||||
```
|
||||
|
||||
与下面👇 `JSON` 大致相同
|
||||
|
||||
```json
|
||||
{
|
||||
"section": {
|
||||
"key1": "a",
|
||||
"key2": "b"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 嵌套(部分解析器支持)
|
||||
|
||||
```ini
|
||||
[section]
|
||||
domain = jaywcjlove.github.io
|
||||
|
||||
[section.subsection]
|
||||
foo = bar
|
||||
```
|
||||
|
||||
与下面👇 `JSON` 大致相同
|
||||
|
||||
```js
|
||||
{
|
||||
"section": {
|
||||
"domain": "jaywcjlove.github.io"
|
||||
"subsection": {
|
||||
"foo": "bar"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
嵌套到上一节(简写)
|
||||
|
||||
```ini
|
||||
[section]
|
||||
domain = jaywcjlove.github.io
|
||||
[.subsection]
|
||||
foo = bar
|
||||
```
|
||||

### Type Casting
|
||||
|
||||
```java
|
||||
// Widening
|
||||
// byte<short<int<long<float<double
|
||||
int i = 10;
|
||||
long l = i; // 10
|
||||
// Narrowing
|
||||
double d = 10.02;
|
||||
long l = (long)d; // 10
|
||||
String.valueOf(10); // "10"
|
||||
Integer.parseInt("10"); // 10
|
||||
Double.parseDouble("10"); // 10.0
|
||||
```
|
||||
|
||||
### 条件语句 Conditionals
|
||||
|
||||
```java
|
||||
int j = 10;
|
||||
if (j == 10) {
|
||||
System.out.println("I get printed");
|
||||
} else if (j > 10) {
|
||||
System.out.println("I don't");
|
||||
} else {
|

Java 字符串
|
||||
-------
|
||||
|
||||
### 基本的
|
||||
|
||||
```java
|
||||
String str1 = "value";
|
||||
String str2 = new String("value");
|
||||
String str3 = String.valueOf(123);
|
||||
```
|
||||
|
||||
### 字符串连接
|
||||
|
||||
```java
|
||||
String s = 3 + "str" + 3; // 3str3
|
||||
String s = 3 + 3 + "str"; // 6str
|
||||
String s = "3" + 3 + "str"; // 33str
|
||||
String s = "3" + "3" + "23"; // 3323
|
||||
String s = "" + 3 + 3 + "23"; // 3323
|
||||
String s = 3 + 3 + 23; // 29
|
||||
```
|
||||
|
||||

### 操纵
|
||||
|
||||
```java
|
||||
String str = "Abcd";
|
||||
str.toUpperCase(); // ABCD
|
||||
str.toLowerCase(); // abcd
|
||||
str.concat("#"); // Abcd#

"ab".toCharArray(); // {'a', 'b'}
|
||||
```
|
||||
|
||||
### 信息
|
||||
|
||||
```java
|
||||
String str = "abcd";
|
||||
str.charAt(2); // c
|
||||
str.indexOf("a") // 0
|
||||
str.indexOf("z") // -1
|
||||
str.length(); // 4

||||
```js
|
||||
app.on('error', (err, ctx) => {
|
||||
log.error('server error', err, ctx)
|
||||
});
|
||||
```
|
||||
|
||||
默认情况下 `Koa` 会将所有错误信息输出到 `stderr`, 除非 `app.silent` 是 `true`。当 `err.status` 是 `404` 或者 `err.expose` 时,默认错误处理程序也不会输出错误
|
||||
|
||||
### Context 示例
|
||||
|
||||
```js
|
||||
app.use(async ctx => {
|
||||
ctx; // 这是上下文 Context
|
||||
ctx.request; // 这是 koa Request
|
||||
ctx.response; // 这是 koa Response
|
||||
});
|
||||
```
|
||||
|
||||
### app.listen(...)
|
||||
<!--rehype:wrap-class=col-span-2 row-span-2-->
|
||||
|
||||
```js
|
||||
const Koa = require('koa');
|
||||
const app = new Koa();
|
||||
app.listen(3000);
|
||||
```
|
||||
|
||||
`app.listen(...)` 实际上是以下代码的语法糖:
|
||||
|
||||
```js
|
||||
const http = require('http');
|
||||
const Koa = require('koa');
|
||||
const app = new Koa();
|
||||
http.createServer(app.callback()).listen(3000);
|
||||
```
|
||||
|
||||
这意味着您可以同时支持 `HTTPS` 和 `HTTPS`,或者在 `多个端口` 监听同一个应用
|
||||
|
||||
```js
|
||||
const http = require('http');
|
||||
const https = require('https');
|
||||
const Koa = require('koa');
|
||||
const app = new Koa();
|
||||
http.createServer(app.callback()).listen(3000);
|
||||
https.createServer(app.callback()).listen(3001);
|
||||
```
|
||||
|
||||
### ctx.throw 示例
|
||||
|
||||
```js
|
||||
ctx.throw(400);
|
||||
ctx.throw(400, 'name required');
|
||||
ctx.throw(400, 'name required', { user: user });
|
||||
```
|
||||
|
||||
`this.throw('name required', 400)` 等价于
|
||||
|
||||
```js
|
||||
const err = new Error('name required');
|
||||
err.status = 400;
|
||||
err.expose = true;
|
||||
throw err;
|
||||
```
|
||||
|
||||
### ctx.assert 示例
|
||||
|
||||
```js
|
||||
ctx.assert(
|
||||
ctx.state.user,
|
||||
401,
|
||||
'User not found. Please login!'
|
||||
);
|
||||
```
|
||||
|
||||

Lerna 备忘清单
|
||||
===
|
||||
|
||||
本备忘单旨在快速理解 [Lerna v6](https://github.com/lerna/lerna) 所涉及的主要概念,显示了它的常用命令使用清单。
|
||||
|
||||
入门

||||
----
|
||||
|
||||
### 介绍
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
现代构建系统,用于管理和发布来自同一存储库的多个 JavaScript/TypeScript 包。
|
||||
|
||||
```bash
|
||||
$ npx lerna@latest init
|
||||
```
|
||||
|
||||
下面是示例目录结构
|
||||
|
||||
```shell {15}
|
||||
├── README.md
|
||||
├── remixapp # web 应用 (remixapp)

|
||||
### 引导程序 (Bootstrap)
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
它在 `package.json` 中依赖于它们,如下所示:
|
||||
|
||||
```json {3,4}
|
||||
"dependencies": {
|
||||
// ....
|
||||
"@remixapp/header": "*",
|
||||
"@remixapp/footer": "*"
|
||||
}
|
||||
```
|
||||
|
||||
`remixapp` 应用程序导入`页眉`和`页脚`库,如下所示:
|
||||
|
||||
```jsx
|
||||
import { Header } from "header";
|
||||
import { Footer } from "footer";
|
||||
|
||||
export default function Home() {
|
||||
return (
|
||||
<>
|
||||
<Header />
|
||||
<div>Content!</div>
|
||||
<Footer />
|
||||
</>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### useWorkspaces
|
||||
|
||||
```json {3}
|
||||
{
|
||||
"$schema": "node_modules/lerna/schemas/lerna-schema.json",
|
||||
"useWorkspaces": true,
|
||||
"version": "0.0.0"
|
||||
}
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
在 `lerna.json` 中配置 `useWorkspaces` 告诉 `Lerna` 将包链接过程委托给你的包管理器 (此功能由 npm、yarn 和 pnpm 支持)。
|
||||
|
||||
### 任务运行
|
||||
|
||||
```bash
|
||||
npx lerna run test --scope=header # 单个
|
||||
```
|
||||
|
||||
多个任务运行
|
||||
|
||||
```bash
|
||||
npx lerna run test --scope=header,footer
|
||||
```
|
||||
|
||||
忽略 `header`,`footer` 其它包中运行任务运行
|
||||
|
||||
```bash
|
||||
npx lerna run build --ignore=header,footer
|
||||
```
|
||||
|
||||

|
||||
|
||||
### run/exec 运行命令
|
||||
|
||||
```bash
|
||||
# 在所有包含它的包中运行 npm run my-script
|
||||
$ lerna run <script> -- [..args]
|
||||
$ lerna run test
|
||||
$ lerna run build
|
||||
|
||||
# 观看所有包并在更改时转换,流式前缀输出
|
||||
$ lerna run --parallel watch
|
||||
|
||||
# 在所有包中运行命令
|
||||
$ lerna exec -- <command> [..args]
|
||||
$ lerna exec -- rm -rf ./node_modules
|
||||
$ lerna exec -- protractor conf.js
|
||||
```

:- | :-
|
||||
:- | :-
|
||||
`--npm-client <client>` [#](https://github.com/lerna/lerna/tree/main/commands/run#--npm-client-client) | 必须是知道如何运行 npm 生命周期脚本的可执行文件,默认值是 `npm`
|
||||
`--stream` [#](https://github.com/lerna/lerna/tree/main/commands/run#--stream) | 立即从子进程流式输出,以原始包名称为前缀
|
||||
`--parallel` [#](https://github.com/lerna/lerna/tree/main/commands/run#--parallel) | 类似于 `--stream` 但完全忽略并发和拓扑排序,立即在所有匹配的包中运行给定的命令或脚本,并带有前缀流输出
|
||||
`--no-bail` [#](https://github.com/lerna/lerna/tree/main/commands/run#--no-bail) | 默认情况下,如果任何脚本运行返回非零退出代码,`lerna run` 将退出并出现错误。传递 `--no-bail` 以禁用此行为
|

|
||||
$ lerna add mod-1 packages/prefix-*
|
||||
# 将 mod-1 安装到mod-2
|
||||
$ lerna add mod-1 --scope=mod-2
|
||||
# 在 devDependencies 中安装 mod-1 到 mod-2
|
||||
$ lerna add mod-1 --scope=mod-2 --dev
|
||||
# 在 peerDependencies 中安装 mod-1 到 mod-2
|
||||
$ lerna add mod-1 --scope=mod-2 --peer
|
||||
# 在除 mod-1 之外的所有模块中安装 mod-1
|
||||
$ lerna add mod-1
|
||||
# 在所有模块中安装 babel-core
|
||||
$ lerna add babel-core
|
||||
```
|
||||
|
||||
### diff
|
||||
|
||||
比较自上次发布以来的所有包或单个包
|
||||
|
||||
```bash
|
||||
$ lerna diff [package]
|
||||
$ lerna diff
|
||||
$ lerna diff package-name # 区分一个特定的包
|
||||
```
|
||||
|
||||
类似于 `lerna changed`,此命令运行 `git diff`
|
||||
|
||||
|
||||
### clean
|
||||
|
||||
从所有包中删除 `node_modules` 目录
|
||||
|
||||
```bash
|
||||
$ lerna clean
|
||||
```
|
||||
|
||||
接受所有[过滤选项](#过滤选项)。`lerna clean` 不会从根 `node_modules` 目录中删除模块,即使您启用了 `--hoist` 选项
|
||||
|
||||
### add-caching
|
||||
|
||||
运行设置基本缓存选项的向导
|
||||
|
||||
```bash
|
||||
$ lerna add-caching
|
||||
```
|
||||
|
||||
### link
|
||||
|
||||
将所有相互依赖的包符号链接在一起
|
||||
|
||||
```bash
|
||||
$ lerna link
|
||||
```
|
||||
|
||||
[`--force-local`](https://github.com/lerna/lerna/tree/main/commands/link#--force-local) 设置会导致链接命令始终对本地依赖项进行符号链接
|
||||
|
||||
### repair
|
||||
|
||||
更新配置文件以匹配当前安装的 lerna 版本
|
||||
|
||||
```bash
|
||||
$ npm i lerna@latest
|
||||
$ lerna repair
|
||||
```
|
||||
|
||||
[`lerna repair`](https://github.com/lerna/lerna/tree/main/core/lerna/commands/repair#usage) 在升级后最有用,可确保应用新版本 lerna 的任何配置文件更改

|
||||
入门
|
||||
---
|
||||
|
||||
### 介绍
|
||||
|
||||
Less(Leaner Style Sheets 的缩写)是一门向后兼容的 [`CSS`](./css.md) 扩展语言
|
||||
|
||||
- [CSS 备忘清单](./css.md) _(jaywcjlove.github.io)_

|
||||
|
||||
在 Node.js 环境中使用 `Less`
|
||||
|
||||
```bash
|
||||
$ npm install -g less
|
||||
$ lessc styles.less styles.css
|
||||
```
|
||||
|
||||
在浏览器环境中使用 `Less`
|
||||
|
||||
```html
|
||||
<link rel="stylesheet/less" type="text/css" href="styles.less" />
|
||||
<script src="https://cdn.jsdelivr.net/npm/less@4" ></script>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 变量(Variables)
|
||||
|
||||
```less
|
||||
@width: 10px;
|
||||
@height: @width + 10px;
|
||||
|
||||
#header {
|
||||
width: @width;
|
||||
height: @height;
|
||||
}
|
||||
```
|
||||
|
||||
编译 css 为:
|
||||
|
||||
```css
|
||||
#header {
|
||||
width: 10px;
|
||||
height: 20px;
|
||||
}
|
||||
```

||||
### 混合(Mixins)
|
||||
|
||||
```less {1,8,13}
|
||||
.bordered {
|
||||
border-top: dotted 1px black;
|
||||
border-bottom: solid 2px black;
|
||||
}
|
||||
|
||||
#menu a {

||||
### 嵌套(Nesting)
|
||||
|
||||
```css
|
||||
#header {
|
||||
color: black;
|
||||
}
|
||||
#header .navigation {
|
||||
font-size: 12px;
|
||||
}
|
||||
#header .logo {
|
||||
width: 300px;
|
||||
}
|
||||
```
|
||||
|
||||
👇👇 更改为 less 的写法 ✅ 👇👇
|
||||
|
||||
```less
|
||||
#header {
|
||||
color: black;
|
||||
.navigation {
|
||||
font-size: 12px;
|
||||
}
|
||||
.logo {
|
||||
width: 300px;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 父选择器 &
|
||||
|
||||
```less
|
||||
.button {
|
||||
color: blue;
|
||||
&-ok {
|
||||
background-image: url("ok.png");
|
||||
}
|
||||
&:hover {
|
||||
color: green;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
编译 css 为:
|
||||
|
||||
```css
|
||||
.button {
|
||||
color: blue;
|
||||
}
|
||||
.button-ok {
|
||||
background-image: url("ok.png");
|
||||
}
|
||||
.button:hover {
|
||||
color: green;
|
||||
}
|
||||
```
|
||||
|
||||
### @规则嵌套和冒泡
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```less
|
||||
.component {
|
||||
width: 300px;
|
||||
@media (min-width: 768px) {
|
||||
width: 600px;
|
||||
@media (min-resolution: 192dpi) {
|
||||
background-image: url(/img/icon2x.png);
|
||||
}
|
||||
}
|
||||
@media (min-width: 1280px) {
|
||||
width: 800px;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
编译 css 为:
|
||||
|
||||
```css
|
||||
.component {
|
||||
width: 300px;
|
||||
}
|
||||
@media (min-width: 768px) {
|
||||
.component {
|
||||
width: 600px;
|
||||
}
|
||||
}
|
||||
@media (min-width: 768px) and (min-resolution: 192dpi) {
|
||||
.component {
|
||||
background-image: url(/img/icon2x.png);
|
||||
}
|
||||
}
|
||||
@media (min-width: 1280px) {
|
||||
.component {
|
||||
width: 800px;
|
||||
}
|
||||
}
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 运算(Operations)
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
算术运算符 `+`、`-`、`*`、`/` 对任何数字、颜色或变量进行运算
|
||||
|
||||
```less
|
||||
@conversion-1: 5cm + 10mm; // 结果是 6cm
|
||||
@conversion-2: 2 - 3cm - 5mm; // 结果 -1.5cm
|
||||
@incompatible-units: 2 + 5px - 3cm;
|
||||
// 结果是 4px
|
||||
@base: 5%;
|
||||
@filler: @base * 2; // 结果是 10%
|
||||
@other: @base + @filler; // 结果是 15%
|
||||
|
||||
@base: 2cm * 3mm; // 结果是 6cm
|
||||
@color: (#224488 / 2); // 结果是 #112244
|
||||
background-color: #112244 + #111;
|
||||
// 结果是 #223355
|
||||
@color: #222 / 2;
|
||||
// 结果是 `#222 / 2`, not #111
|
||||
background-color: (#FFFFFF / 16);
|
||||
// 结果是 #101010
|
||||
```
|
||||
|
||||
#### calc() 特例
|
||||
|
||||
为了与 `CSS` 保持兼容,`calc()` 并不对数学表达式进行计算,但是在嵌套函数中会计算变量和数学公式的值
|
||||
|
||||
```less
|
||||
@var: 50vh/2;
|
||||
width: calc(50% + (@var - 20px));
|
||||
// 结果是 calc(50% + (25vh - 20px))
|
||||
```
|
||||
|
||||
### 转义(Escaping)
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```less
|
||||
@min768: ~"(min-width: 768px)";
|
||||
.element {
|
||||
@media @min768 {
|
||||
font-size: 1.2rem;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
编译 css 为:
|
||||
|
||||
```css
|
||||
@media (min-width: 768px) {
|
||||
.element {
|
||||
font-size: 1.2rem;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
从 Less 3.5 开始,可以简写为
|
||||
|
||||
```less
|
||||
@min768: (min-width: 768px);
|
||||
.element {
|
||||
@media @min768 {
|
||||
font-size: 1.2rem;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
在 Less 3.5+ 版本中,许多以前需要“引号转义”的情况就不再需要了
|
||||
|
||||
### 函数(Functions)
|
||||
|
||||
```less
|
||||
@base: #f04615;
|
||||
@width: 0.5;
|
||||
|
||||
.class {
|
||||
width: percentage(@width); // 返回 `50%`
|
||||
color: saturate(@base, 5%);
|
||||
background-color:
|
||||
spin(lighten(@base, 25%), 8);
|
||||
}
|
||||
```
|
||||
|
||||
Less 内置了多种函数用于转换颜色、处理字符串、算术运算等
|
||||
|
||||
### 命名空间和访问符
|
||||
|
||||
```less
|
||||
#bundle() {
|
||||
.button {
|
||||
display: block;
|
||||
border: 1px solid black;
|
||||
background-color: grey;
|
||||
&:hover {
|
||||
background-color: white;
|
||||
}
|
||||
}
|
||||
.tab { ... }
|
||||
.citation { ... }
|
||||
}
|
||||
```
|
||||
|
||||
把 `.button` 类混合到 `#header a` 中,我们可以这样做
|
||||
|
||||
```less
|
||||
#header a {
|
||||
color: orange;
|
||||
#bundle.button();
|
||||
// 还可以书写为 #bundle > .button 形式
|
||||
}
|
||||
```
|
||||
|
||||
### 映射(Maps)
|
||||
|
||||
```less
|
||||
#colors() {
|
||||
primary: blue;
|
||||
secondary: green;
|
||||
}
|
||||
|
||||
.button {
|
||||
color: #colors[primary];
|
||||
border: 1px solid #colors[secondary];
|
||||
}
|
||||
```
|
||||
|
||||
输出符合预期(css):
|
||||
|
||||
```css
|
||||
.button {
|
||||
color: blue;
|
||||
border: 1px solid green;
|
||||
}
|
||||
```
|
||||
|
||||
另见:[映射(Maps)](https://lesscss.org/features/#maps-feature)
|
||||
|
||||
### 作用域(Scope)
|
||||
|
||||
```less
|
||||
@var: red;
|
||||
|
||||
#page {
|
||||
@var: white;
|
||||
#header {
|
||||
color: @var; // white
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
和上面实例代码相同
|
||||
|
||||
```less
|
||||
@var: red;
|
||||
|
||||
#page {
|
||||
#header {
|
||||
color: @var; // white
|
||||
}
|
||||
@var: white;
|
||||
}
|
||||
```
|
||||
|
||||
另见:[懒加载](https://lesscss.org/features/#variables-feature-lazy-loading)
|
||||
|
||||
### 注释(Comments)
|
||||
|
||||
```less
|
||||
/* 一个块注释
|
||||
* style comment! */
|
||||
@var: red;
|
||||
|
||||
// 这一行被注释掉了!
|
||||
@var: white;
|
||||
```
|
||||
|
||||
块注释和行注释都可以使用
|
||||
|
||||
### 导入(Importing)

Sass
|
||||
===
|
||||
|
||||
这是一份快速参考备忘单,列出了 [SASS](https://sass-lang.com) 最有用的功能。
|
||||
|
||||
Sass 基础
|
||||
--------
|
||||
|
||||
### 介绍
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
- [Sass 官方文档](https://sass-lang.com/documentation) _(sass-lang.com)_
|
||||
- [Sass 中文文档](https://www.sass.hk/docs/) _(sass.hk)_
|
||||
|
||||
Sass 是一种 CSS 的预编译语言
|
||||
|
||||
```bash
|
||||
$ npm install -g sass
|
||||
```
|
||||
|
||||
在 Node.js 环境中使用 Sass
|
||||
|
||||
```bash
|
||||
$ sass source/index.scss build/index.css
|
||||
$ sass --watch input.scss output.css
|
||||
$ sass --watch app/sass:public/css
|
||||
```
|
||||
|
||||
### 变量
|
||||
|
||||
```scss
|
||||
$defaultLinkColor: #46EAC2;
|
||||
a {
|
||||
color: $defaultLinkColor;
|
||||
}
|
||||
```
|
||||
|
||||
### 字符串插值
|
||||
|
||||
```scss
|
||||
$wk: -webkit-;
|
||||
.rounded-box {
|
||||
#{$wk}border-radius: 4px;
|
||||
}
|
||||
```
|
||||
|
||||
### 注释
|
||||
|
||||
```scss
|
||||
/*
|
||||
这是多行注释
|
||||
块注释
|
||||
块注释
|
||||
*/
|
||||
// 这是一条单行注释
|
||||
```
|
||||
|
||||
### Extend
|
||||
|
||||
```scss
|
||||
.button {
|
||||
···
|
||||
}
|
||||
.push-button {
|
||||
@extend .button;
|
||||
}
|
||||
```
|
||||
|
||||
### 嵌套(Nesting)
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```scss
|
||||
nav {
|
||||
ul {
|
||||
padding: 0;
|
||||
list-style: none;
|
||||
}
|
||||
li { display: inline-block; }
|
||||
a {
|
||||
display: block;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
编译 css 为:
|
||||
|
||||
```scss
|
||||
nav ul {
|
||||
padding: 0;
|
||||
list-style: none;
|
||||
}
|
||||
nav li {
|
||||
display: inline-block;
|
||||
}
|
||||
nav a {
|
||||
display: block;
|
||||
}
|
||||
```
|
||||
|
||||
### 模块(片段)
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```scss
|
||||
// _base.scss
|
||||
$font-stack: Helvetica, sans-serif;
|
||||
$primary-color: #333;
|
||||
```
|
||||
|
||||
注意以下划线开头的 Sass 文件
|
||||
|
||||
```scss
|
||||
// styles.scss
|
||||
@use 'base';
|
||||
|
||||
.inverse {
|
||||
background-color: base.$primary-color;
|
||||
color: white;
|
||||
}
|
||||
```
|
||||
|
||||
编译 css 为:
|
||||
|
||||
```css
|
||||
.inverse {
|
||||
background-color: #333;
|
||||
color: white;
|
||||
}
|
||||
```
|
||||
|
||||
### 混合(Mixins)
|
||||
|
||||
```scss
|
||||
@mixin heading-font {
|
||||
font-family: sans-serif;
|
||||
font-weight: bold;
|
||||
}
|
||||
h1 {
|
||||
@include heading-font;
|
||||
}
|
||||
```
|
||||
|
||||
查看: [混合(Mixins)](#sass-混合mixins)
|
||||
|
||||
### @import
|
||||
|
||||
```scss
|
||||
@import './other_sass_file';
|
||||
@import '/code', 'lists';
|
||||
// 纯 CSS @imports
|
||||
@import "theme.css";
|
||||
@import url(theme);
|
||||
```
|
||||
|
||||
`.sass` 或 `.sass` 扩展名是可选的。

||||
|
||||
```scss
|
||||
rgb(100, 120, 140)
|
||||
rgba(100, 120, 140, .5)
|
||||
rgba($color, .5)
|
||||
```
|
||||
|
||||
### Mixing
|
||||
|
||||
```scss
|
||||
mix($a, $b, 10%) // 10% a, 90% b
|
||||
```
|
||||
|
||||
### 修改 HSLA
|
||||
|
||||
```scss
|
||||
darken($color, 5%)

|
||||
```
|
||||
|
||||
```scss
|
||||
saturate($color, 5%)

|
||||
grayscale($color)
|
||||
```
|
||||
|
||||
```scss
|
||||
adjust-hue($color, 15deg)
|
||||
complement($color) // like adjust-hue(_, 180deg)
|
||||
invert($color)
|
||||
```
|
||||
|
||||
```scss
|
||||
fade-in($color, .5) // aka opacify()
|
||||
fade-out($color, .5) // aka transparentize()
|
||||
rgba($color, .5) // sets alpha to .5
|
||||
```
|
||||
|
||||
### 获取值
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
#### HSLA

||||
|
||||
```scss
|
||||
red($color) // 0..255

### Sass 内置了对颜色值的支持
|
||||
|
||||
```scss
|
||||
@debug rgb(204, 102, 153); // #c69
|
||||
@debug rgba(107, 113, 127, 0.8); // rgba(107, 113, 127, 0.8)
|
||||
@debug hsl(228, 7%, 86%); // #dadbdf
|
||||
@debug hsla(20, 20%, 85%, 0.7); // rgb(225, 215, 210, 0.7)
|
||||
```
|
||||
|
||||
### 调整
|
||||
|
||||
```scss
|
||||
// 固定金额变动
|
||||
adjust-color($color, $blue: 5)
|
||||
adjust-color($color, $lightness: -30%) // darken(_, 30%)
|
||||
adjust-color($color, $alpha: -0.4) // fade-out(_, .4)
|
||||
adjust-color($color, $hue: 30deg) // adjust-hue(_, 15deg)
|
||||
// 通过百分比变化
|
||||
scale-color($color, $lightness: 50%)
|
||||
// 完全改变一个属性
|
||||
change-color($color, $hue: 180deg)
|
||||
change-color($color, $blue: 250)
|
||||
```
|
||||
|
||||
支持的: `$red`, `$green`, `$blue`, `$hue`, `$saturation`, `$lightness`, `$alpha`

|
||||
===
|
||||
|
||||
本备忘单旨在快速理解 [stylus](https://github.com/stylus/stylus) 所涉及的主要概念,显示了它的常用方法使用清单。
|
||||
|
||||
入门
|
||||
---
|
||||
|
||||
### 介绍
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
为 Node.js 构建的富有表现力、健壮、功能丰富的 [CSS](./css.md) 语言
|
||||
|
||||
- [CSS 备忘清单](./css.md) _(jaywcjlove.github.io)_
|
||||
- [在线编译预览](https://stylus-lang.com/try.html) _(stylus-lang.com)_
|
||||
|
||||
```bash
|
||||
# npm
|
||||
$ npm install stylus -g
|
||||
# pnpm
|
||||
$ pnpm add -g stylus
|
||||
```
|
||||
|
||||
在 Node.js 环境中使用 `stylus`
|
||||
|
||||
```bash
|
||||
$ stylus one.styl two.styl
|
||||
# stylus 从标准输入读取并输出到标准输出
|
||||
$ stylus --compress < some.styl > some.css
|
||||
# 将 css 目录中的文件编译输出到 `public/css`
|
||||
$ stylus css --out public/css
|
||||
```
|
||||
|
||||
转换 CSS,输出 `*.styl` 文件
|
||||
|
||||
```
|
||||
$ stylus --css < test.css > test.styl
|
||||
$ stylus --css test.css /tmp/out.styl
|
||||
```
|
||||
|
||||
### 支持 CSS 嵌套语法
|
||||
|
||||
```stylus
|
||||
.box {
|
||||
color: blue;
|
||||
.button {
|
||||
color: red;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Stylus 是一个 CSS 预处理器。另见: [stylus-lang.com](http://stylus-lang.com/)
|
||||
|
||||
### 支持类 python 缩进语法
|
||||
|
||||
```stylus
|
||||
.box
|
||||
color: blue
|
||||
.button
|
||||
color: red
|
||||
```

Vue 3 备忘清单
|
||||
===
|
||||
|
||||
渐进式 JavaScript 框架 [Vue 3](https://cn.vuejs.org/) 备忘清单的快速参考列表,包含常用 API 和示例。
|
||||
|
||||
|
||||
入门
|
||||
---
|
||||
|
||||
### 介绍
|
||||
|
||||
Vue 是一套用于构建用户界面的渐进式框架
|
||||
|
||||
- [Vue 3.x 官方文档](https://cn.vuejs.org/)
|
||||
- [Vue Router 4.x 官方文档](https://router.vuejs.org/zh/)
|
||||
<!--rehype:className=style-round-->
|
||||
|
||||
注意:Vue 3.x 版本对应 Vue Router 4.x 路由版本
|
||||
|
||||
### 创建应用
|
||||
<!--rehype:wrap-class=row-span-3-->
|
||||
|
||||
已安装 `16.0` 或更高版本的 Node.js
|
||||
|
||||
```bash
|
||||
$ npm init vue@latest
|
||||
```
|
||||
|
||||
指令将会安装并执行 [create-vue](https://www.npmjs.com/package/create-vue),它是 Vue 官方的项目脚手架工具
|
||||
|
||||
```bash
|
||||
✔ Project name: … <your-project-name>
|
||||
✔ Add TypeScript? … No/Yes
|
||||
✔ Add JSX Support? … No/Yes
|
||||
✔ Add Vue Router for Single Page Application development? … No/Yes
|
||||
✔ Add Pinia for state management? … No/Yes
|
||||
✔ Add Vitest for Unit testing? … No/Yes
|
||||
✔ Add Cypress for both Unit and End-to-End testing? … No/Yes
|
||||
✔ Add ESLint for code quality? … No/Yes
|
||||
✔ Add Prettier for code formatting? … No/Yes
|
||||
|
||||
Scaffolding project in ./<your-project-name>...
|
||||
Done.
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
安装依赖并启动开发服务器
|
||||
|
||||
```bash
|
||||
$ cd <your-project-name>
|
||||
$ npm install
|
||||
$ npm run dev
|
||||
```
|
||||
|
||||
当你准备将应用发布到生产环境时,请运行:
|
||||
|
||||
```bash
|
||||
$ npm run build
|
||||
```
|
||||
|
||||
此命令会在 `./dist` 文件夹中为你的应用创建一个生产环境的构建版本
|
||||
|
||||
### 应用实例
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```js
|
||||
import { createApp } from 'vue'
|
||||
|
||||
const app = createApp({
|
||||
data() {
|
||||
return { count: 0 }
|
||||
}
|
||||
})
|
||||
app.mount('#app')
|
||||
```
|
||||
|
||||
挂载应用
|
||||
|
||||
```html
|
||||
<div id="app">
|
||||
<button @click="count++">
|
||||
{{ count }}
|
||||
</button>
|
||||
</div>
|
||||
```
|
||||
|
||||
### 通过 CDN 使用 Vue
|
||||
|
||||
```html
|
||||
<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>
|
||||
<div id="app">{{ message }}</div>
|
||||
<script>
|
||||
const { createApp } = Vue
|
||||
createApp({
|
||||
data() {
|
||||
return {
|
||||
message: 'Hello Vue!'
|
||||
}
|
||||
}
|
||||
}).mount('#app')
|
||||
</script>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 使用 ES 模块构建版本
|
||||
|
||||
```html
|
||||
<div id="app">{{ message }}</div>
|
||||
<script type="module">
|
||||
import { createApp } from 'https://unpkg.com/vue@3/dist/vue.esm-browser.js'
|
||||
createApp({
|
||||
data() {
|
||||
return {
|
||||
message: 'Hello Vue!'
|
||||
}
|
||||
}
|
||||
}).mount('#app')
|
||||
</script>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
模板语法
|
||||
---
|
||||
|
||||
### 文本插值
|
||||
|
||||
```html
|
||||
<span>Message: {{ msg }}</span>
|
||||
```
|
||||
|
||||
使用的是 `Mustache` 语法 (即双大括号),每次 `msg` 属性更改时它也会同步更新
|
||||
|
||||
### 原始 HTML
|
||||
<!--rehype:wrap-class=col-span-2-->
|
||||
|
||||
```html
|
||||
<p>Using text interpolation: {{ rawHtml }}</p>
|
||||
<p>Using v-html directive: <span v-html="rawHtml"></span></p>
|
||||
```
|
||||
|
||||
双大括号`{{}}`会将数据解释为纯文本,使用 `v-html` 指令,将插入 HTML
|
||||
|
||||
### Attribute 绑定
|
||||
|
||||
```html
|
||||
<div v-bind:id="dynamicId"></div>
|
||||
```
|
||||
|
||||
简写
|
||||
|
||||
```html
|
||||
<div :id="dynamicId"></div>
|
||||
```
|
||||
|
||||
### 布尔型 Attribute
|
||||
|
||||
```html
|
||||
<button :disabled="isButtonDisabled">
|
||||
Button
|
||||
</button>
|
||||
```
|
||||
<!--rehype:className=wrap-text -->
|
||||
|
||||
### 动态绑定多个值
|
||||
<!--rehype:wrap-class=row-span-2-->
|
||||
|
||||
```js
|
||||
data() {
|
||||
return {
|
||||
objectOfAttrs: {
|
||||
id: 'container',
|
||||
class: 'wrapper'
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
通过不带参数的 `v-bind`,你可以将它们绑定到单个元素上
|
||||
|
||||
```html
|
||||
<div v-bind="objectOfAttrs"></div>
|
||||
```
|
||||
|
||||
### 使用 JavaScript 表达式
|
||||
|
||||
```html
|
||||
{{ number + 1 }}
|
||||
{{ ok ? 'YES' : 'NO' }}
|
||||
{{ message.split('').reverse().join('') }}
|
||||
|
||||
<div :id="`list-${id}`"></div>
|
||||
```
|
||||
|
||||
### 仅支持表达式(例子都是无效)
|
||||
|
||||
```html
|
||||
<!-- 这是一个语句,而非表达式 -->
|
||||
{{ var a = 1 }}
|
||||
<!-- 条件控制也不支持,请使用三元表达式 -->
|
||||
{{ if (ok) { return message } }}
|
||||
```
|
||||
|
||||
### 调用函数
|
||||
|
||||
```html
|
||||
<span :title="toTitleDate(date)">
|
||||
{{ formatDate(date) }}
|
||||
</span>
|
||||
```
|
||||
|
||||
|
||||
### 指令 Directives
|
||||
|
||||
```html
|
||||
<p v-if="seen">Now you see me</p>
|
||||
```
|
||||
|
||||
### 参数 Arguments
|
||||
|
||||
```html
|
||||
<a v-bind:href="url"> ... </a>
|
||||
<!-- 简写 -->
|
||||
<a :href="url"> ... </a>
|
||||
```
|
||||
|
||||
### 绑定事件
|
||||
|
||||
```html
|
||||
<a v-on:click="doSomething"> ... </a>
|
||||
<!-- 简写 -->
|
||||
<a @click="doSomething"> ... </a>
|
||||
```
|
||||
|
||||
### 动态参数
|
||||
|
||||
```html
|
||||
<a v-bind:[attributeName]="url"> ... </a>
|
||||
<!-- 简写 -->
|
||||
<a :[attributeName]="url"> ... </a>
|
||||
```
|
||||
|
||||
这里的 `attributeName` 会作为一个 JS 表达式被动态执行
|
||||
|
||||
### 动态的事件名称
|
||||
|
||||
```html
|
||||
<a v-on:[eventName]="doSomething"> ... </a>
|
||||
<!-- 简写 -->
|
||||
<a @[eventName]="doSomething">
|
||||
```
|
||||
|
||||
### 修饰符 Modifiers
|
||||
|
||||
```html
|
||||
<form @submit.prevent="onSubmit">
|
||||
...
|
||||
</form>
|
||||
```
|
||||
|
||||
`.prevent` 修饰符会告知 `v-on` 指令对触发的事件调用 `event.preventDefault()`
|
||||
|
||||
### 指令语法
|
||||
|
||||
```bash
|
||||
v-on:submit.prevent="onSubmit"
|
||||
──┬─ ─┬──── ─┬───── ─┬──────
|
||||
