Expressive Code#

语法高亮#

常规语法高亮#

1
console.log('This code is syntax highlighted!')

渲染 ANSI 转义序列#

1
ANSI colors:
2
- Regular: Red Green Yellow Blue Magenta Cyan
3
- Bold:    Red Green Yellow Blue Magenta Cyan
4
- Dimmed:  Red Green Yellow Blue Magenta Cyan
5

Text formatting: Bold Dimmed Italic Underline

编辑器与终端边框#

编辑器与终端边框

代码编辑器边框#

1
console.log('Title attribute example')

1
<div>File name comment example</div>

终端边框#

1
echo "This terminal frame has no title"

1
Write-Output "This one has a title!"

覆盖默认边框类型#

1
echo "Look ma, no frame!"

1
# Without overriding, this would be a terminal frame
2
function Watch-Tail { Get-Content -Tail 20 -Wait $args }
3
New-Alias tail Watch-Tail

文本与行标记#

文本与行标记

标记整行与行范围#

1
// Line 1 - targeted by line number
2
// Line 2
3
// Line 3
4
// Line 4 - targeted by line number
5
// Line 5
6
// Line 6
7
// Line 7 - targeted by range "7-8"
8
// Line 8 - targeted by range "7-8"

选择行标记类型（mark、ins、del）#

1
function demo() {
2
  console.log('this line is marked as deleted')
3
  // This line and the next one are marked as inserted
4
  console.log('this is the second inserted line')
5

6
  return 'this line uses the neutral default marker type'
7
}

为行标记添加标签#

1
<button
2
  role="button"
3
  {...props}
4
  value={value}
5
  className={buttonClassName}
6
  disabled={disabled}
7
  active={active}
8
>
9
  {children &&
10
    !active &&
11
    (typeof children === 'string' ? <span>{children}</span> : children)}
12
</button>

在独立行中添加长标签#

1
<button
2
  role="button"
3
  {...props}
4

5
  value={value}
6
  className={buttonClassName}
7

8
  disabled={disabled}
9
  active={active}
10
>
11

12
  {children &&
13
    !active &&
14
    (typeof children === 'string' ? <span>{children}</span> : children)}
15
</button>

使用类似 diff 的语法#

1
this line will be marked as inserted
2
this line will be marked as deleted
3
this is a regular line

1
--- a/README.md
2
+++ b/README.md
3
@@ -1,3 +1,4 @@
4
+this is an actual diff file
5
-all contents will remain unmodified
6
 no whitespace will be removed either

结合语法高亮与 diff 风格语法#

1
function thisIsJavaScript() {
2
  // This entire block gets highlighted as JavaScript,
3
  // and we can still add diff markers to it!
4
  console.log('Old code to be removed')
5
  console.log('New and shiny code!')
6
}

标记行内的特定文本#

1
function demo() {
2
  // Mark any given text inside lines
3
  return 'Multiple matches of the given text are supported';
4
}

正则表达式#

1
console.log('The words yes and yep will be marked.')

转义正斜杠#

1
echo "Test" > /home/test.txt

选择行内标记类型（mark、ins、del）#

1
function demo() {
2
  console.log('These are inserted and deleted marker types');
3
  // The return statement uses the default marker type
4
  return true;
5
}

自动换行#

自动换行

为单个代码块配置自动换行#

1
// Example with wrap
2
function getLongString() {
3
  return 'This is a very long string that will most probably not fit into the available space unless the container is extremely wide'
4
}

1
// Example with wrap=false
2
function getLongString() {
3
  return 'This is a very long string that will most probably not fit into the available space unless the container is extremely wide'
4
}

配置换行内容的缩进#

1
// Example with preserveIndent (enabled by default)
2
function getLongString() {
3
  return 'This is a very long string that will most probably not fit into the available space unless the container is extremely wide'
4
}

1
// Example with preserveIndent=false
2
function getLongString() {
3
  return 'This is a very long string that will most probably not fit into the available space unless the container is extremely wide'
4
}

可折叠区域#

可折叠区域


5 collapsed lines
1
// All this boilerplate setup code will be collapsed
2
import { someBoilerplateEngine } from '@example/some-boilerplate'
3
import { evenMoreBoilerplate } from '@example/even-more-boilerplate'
4

5
const engine = someBoilerplateEngine(evenMoreBoilerplate())
6

7
// This part of the code will be visible by default
8
engine.doSomething(1, 2, 3, calcFn)
9

10
function calcFn() {
11
  // You can have multiple collapsed sections
3 collapsed lines
12
  const a = 1
13
  const b = 2
14
  const c = a + b
15

16
  // This will remain visible
17
  console.log(`Calculation result: ${a} + ${b} = ${c}`)
18
  return c
19
}
20

4 collapsed lines
21
// All this code until the end of the block will be collapsed again
22
engine.closeConnection()
23
engine.freeMemory()
24
engine.shutdown({ reason: 'End of example boilerplate code' })

行号#

行号

为单个代码块显示行号#

1
// This code block will show line numbers
2
console.log('Greetings from line 2!')
3
console.log('I am on line 3')

// Line numbers are disabled for this block
console.log('Hello?')
console.log('Sorry, do you know what line I am on?')

修改起始行号#

5
console.log('Greetings from line 5!')
6
console.log('I am on line 6')
