表达式代码示例
在这里,我们将探讨代码块的外观如何,使用表达代码.提供的示例基于官方文档,您可以参考相关文档了解更多细节。
表达代码
语法高亮
常规语法高亮
console.log('This code is syntax highlighted!')
渲染ANSI转义序列
ANSI colors:
- Regular: Red Green Yellow Blue Magenta Cyan
- Bold: Red Green Yellow Blue Magenta Cyan
- Dimmed: Red Green Yellow Blue Magenta Cyan
256 colors (showing colors 160-177):
160 161 162 163 164 165
166 167 168 169 170 171
172 173 174 175 176 177
Full RGB colors:
ForestGreen - RGB(34, 139, 34)
Text formatting: Bold Dimmed Italic Underline
编辑器与终端帧
代码编辑器帧
console.log('Title attribute example')
<!-- src/content/index.html -->
<div>File name comment example</div>
终端帧
echo "This terminal frame has no title"
Write-Output "This one has a title!"
覆盖框架类型
echo "Look ma, no frame!"
# Without overriding, this would be a terminal frame
function Watch-Tail { Get-Content -Tail 20 -Wait $args }
New-Alias tail Watch-Tail
文本与行标记
标记全线和线范围
// Line 1 - targeted by line number
// Line 2
// Line 3
// Line 4 - targeted by line number
// Line 5
// Line 6
// Line 7 - targeted by range "7-8"
// Line 8 - targeted by range "7-8"
Selecting line marker types (mark, ins, del)
function demo() {
console.log('this line is marked as deleted')
// This line and the next one are marked as inserted
console.log('this is the second inserted line')
return 'this line uses the neutral default marker type'
}
Adding labels to line markers
// labeled-line-markers.jsx
<button
role="button"
{...props}
value={value}
className={buttonClassName}
disabled={disabled}
active={active}
>
{children &&
!active &&
(typeof children === 'string' ? <span>{children}</span> : children)}
</button>
Adding long labels on their own lines
// labeled-line-markers.jsx
<button
role="button"
{...props}
value={value}
className={buttonClassName}
disabled={disabled}
active={active}
>
{children &&
!active &&
(typeof children === 'string' ? <span>{children}</span> : children)}
</button>
Using diff-like syntax
+this line will be marked as inserted
-this line will be marked as deleted
this is a regular line
--- a/README.md
+++ b/README.md
@@ -1,3 +1,4 @@
+this is an actual diff file
-all contents will remain unmodified
no whitespace will be removed either
Combining syntax highlighting with diff-like syntax
function thisIsJavaScript() {
// This entire block gets highlighted as JavaScript,
// and we can still add diff markers to it!
- console.log('Old code to be removed')
+ console.log('New and shiny code!')
}
Marking individual text inside lines
function demo() {
// Mark any given text inside lines
return 'Multiple matches of the given text are supported';
}
Regular expressions
console.log('The words yes and yep will be marked.')
Escaping forward slashes
echo "Test" > /home/test.txt
Selecting inline marker types (mark, ins, del)
function demo() {
console.log('These are inserted and deleted marker types');
// The return statement uses the default marker type
return true;
}
Word Wrap
Configuring word wrap per block
// Example with wrap
function getLongString() {
return 'This is a very long string that will most probably not fit into the available space unless the container is extremely wide'
}
// Example with wrap=false
function getLongString() {
return 'This is a very long string that will most probably not fit into the available space unless the container is extremely wide'
}
Configuring indentation of wrapped lines
// Example with preserveIndent (enabled by default)
function getLongString() {
return 'This is a very long string that will most probably not fit into the available space unless the container is extremely wide'
}
// Example with preserveIndent=false
function getLongString() {
return 'This is a very long string that will most probably not fit into the available space unless the container is extremely wide'
}
Collapsible Sections
// All this boilerplate setup code will be collapsed
import { someBoilerplateEngine } from '@example/some-boilerplate'
import { evenMoreBoilerplate } from '@example/even-more-boilerplate'
const engine = someBoilerplateEngine(evenMoreBoilerplate())
// This part of the code will be visible by default
engine.doSomething(1, 2, 3, calcFn)
function calcFn() {
// You can have multiple collapsed sections
const a = 1
const b = 2
const c = a + b
// This will remain visible
console.log(`Calculation result: ${a} + ${b} = ${c}`)
return c
}
// All this code until the end of the block will be collapsed again
engine.closeConnection()
engine.freeMemory()
engine.shutdown({ reason: 'End of example boilerplate code' })
Line Numbers
Displaying line numbers per block
// This code block will show line numbers
console.log('Greetings from line 2!')
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?')
Changing the starting line number
console.log('Greetings from line 5!')
console.log('I am on line 6')
