New Feature

Moe Counter Sidebar

在components的widget里面新建一个.astro文件，调用原生的接口就可以了。这里是直接拿tags.astro改的，非常简单的开发。

对于一个纯静态的网页来说，拥有一个动态的内容显然不是很现实，所以用moe counter来解决了。

创建一个专属的name
把定制的tag直接添加到生成的链接里
链接直接就是一张图片可以嵌入到网页里

整个实现非常轻量化而且取巧，把图床和计数融合到了一块，可能我之后会把这个库拉到本地自己做一个服务吧，毕竟我也想要自定义图片。

Bug Fix

对于组件渲染，Fuwari这个项目为网页写了'main.css'，为Markdown渲染又额外写了'markdown.css'。而这其中是部分重复的，可以理解为互相引用，但是原demo并没有用到重复的组件，所以这个bug就成功的活了下来。我在开发Visitors功能的使用使用了'link'，就产生了编译错误的问题。解决方案是创建一个新的补丁把重复的整合到一块，避免了反复call导致的问题。
Catogories.astro存在嵌套渲染以及tag严格匹配问题

Expressive Code Example

Wed, 10 Apr 2024 00:00:00 GMT

Here, we'll explore how code blocks look using Expressive Code. The provided examples are based on the official documentation, which you can refer to for further details.

Expressive Code

Syntax Highlighting

Regular syntax highlighting

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

Rendering ANSI escape sequences

ANSI colors:
- Regular: [31mRed[0m [32mGreen[0m [33mYellow[0m [34mBlue[0m [35mMagenta[0m [36mCyan[0m
- Bold:    [1;31mRed[0m [1;32mGreen[0m [1;33mYellow[0m [1;34mBlue[0m [1;35mMagenta[0m [1;36mCyan[0m
- Dimmed:  [2;31mRed[0m [2;32mGreen[0m [2;33mYellow[0m [2;34mBlue[0m [2;35mMagenta[0m [2;36mCyan[0m

256 colors (showing colors 160-177):
[38;5;160m160 [38;5;161m161 [38;5;162m162 [38;5;163m163 [38;5;164m164 [38;5;165m165[0m
[38;5;166m166 [38;5;167m167 [38;5;168m168 [38;5;169m169 [38;5;170m170 [38;5;171m171[0m
[38;5;172m172 [38;5;173m173 [38;5;174m174 [38;5;175m175 [38;5;176m176 [38;5;177m177[0m

Full RGB colors:
[38;2;34;139;34mForestGreen - RGB(34, 139, 34)[0m

Text formatting: [1mBold[0m [2mDimmed[0m [3mItalic[0m [4mUnderline[0m

Editor & Terminal Frames

Code editor frames

console.log('Title attribute example')

<!-- src/content/index.html -->
<div>File name comment example</div>

Terminal frames

echo "This terminal frame has no title"

Write-Output "This one has a title!"

Overriding frame types

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

Text & Line Markers

Marking full lines & line ranges

// 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')

Markdown Example

An h1 header

Paragraphs are separated by a blank line.

2nd paragraph. Italic, bold, and monospace. Itemized lists look like:

this one
that one
the other one

Note that --- not considering the asterisk --- the actual text content starts at 4-columns in.

Block quotes are written like so.

They can span multiple paragraphs, if you like.

Use 3 dashes for an em-dash. Use 2 dashes for ranges (ex., "it's all in chapters 12--14"). Three dots ... will be converted to an ellipsis. Unicode is supported. ☺

An h2 header

Here's a numbered list:

first item
second item
third item

Note again how the actual text starts at 4 columns in (4 characters from the left side). Here's a code sample:

# Let me re-iterate ...
for i in 1 .. 10 { do-something(i) }

As you probably guessed, indented 4 spaces. By the way, instead of indenting the block, you can use delimited blocks, if you like:

define foobar() {
    print "Welcome to flavor country!";
}

(which makes copying & pasting easier). You can optionally mark the delimited block for Pandoc to syntax highlight it:

import time
# Quick, count to ten!
for i in range(10):
    # (but not *too* quick)
    time.sleep(0.5)
    print i

An h3 header

Now a nested list:

First, get these ingredients:
- carrots
- celery
- lentils
Boil some water.

Dump everything in the pot and follow this algorithm:

 find wooden spoon
 uncover pot
 stir
 cover pot
 balance wooden spoon precariously on pot handle
 wait 10 minutes
 goto first step (or shut off burner when done)

Do not bump wooden spoon or it will fall.

Notice again how text always lines up on 4-space indents (including that last line which continues item 3 above).

Here's a link to a website, to a local doc, and to a section heading in the current doc. Here's a footnote [^1].

[^1]: Footnote text goes here.

Tables can look like this:

size material color

9 leather brown 10 hemp canvas natural 11 glass transparent

Table: Shoes, their sizes, and what they're made of

(The above is the caption for the table.) Pandoc also supports multi-line tables:

keyword text

red Sunsets, apples, and other red or reddish things.

green Leaves, grass, frogs and other things it's not easy being.

A horizontal rule follows.

Here's a definition list:

apples : Good for making applesauce. oranges : Citrus! tomatoes : There's no "e" in tomatoe.

Again, text is indented 4 spaces. (Put a blank line between each term/definition pair to spread things out more.)

Here's a "line block":

| Line one | Line too | Line tree

and images can be specified like so:

Inline math equations go in like so: $\omega = d\phi / dt$. Display math should get its own line and be put in in double-dollarsigns:

$$I = \int \rho R^{2} dV$$

$$ \begin{equation*} \pi =3.1415926535 ;8979323846;2643383279;5028841971;6939937510;5820974944 ;5923078164;0628620899;8628034825;3421170679;\ldots \end{equation*} $$

And note that you can backslash-escape any punctuation characters which you wish to be displayed literally, ex.: `foo`, *bar*, etc.
