obsidian最强数学公式插件：latex suite文档翻译

对于日常使用markdown做笔记涉及数学公式来说，latex suite这个插件不要太方便。只要输入几个关键字（触发器）就能出来完整的latex公式。下面把官方文档和默认的触发器功能翻译一下。

Snippets 代码片段

Snippets are formatted as follows: 代码片段格式如下：

{trigger: string, replacement: string, options: string, description?: string, priority?: number}

• trigger : The text that triggers this snippet.
• 触发器:触发代码的文字
• replacement : The text to replace the trigger with.
• 替换内容:替换触发器的文本
• options : See below.
• 选项:看下面的解释
• priority (optional): This snippet’s priority. Snippets with higher priority are run first. Can be negative. Defaults to 0.
• 优先级:可选。代码片段优先级。高优先级的代码片段先运行。可以是负数，默认是0.
• description (optional): A description for this snippet.
• 描述:可选。代码片段的注释。

Options选项

• m : Math mode. Only run this snippet inside math
• m：数学模式，这个片段只在数学公式内有效。($$代码段)
• t : Text mode. Only run this snippet outside math
• t:文本模式。这个片段只在数学公式外有效。
• A : Auto. Expand this snippet as soon as the trigger is typed. If omitted, the Tab key must be pressed to expand the snippet
• A:自动。一旦输入触发器文字，就自动替换为代码段。如果没有此参数，必须要按下Tab键才会触发替换。
• r : Regex. The trigger will be treated as a regular expression
• r:正则表达式。触发器会被当做公式表达式。
• w : Word boundary. Only run this snippet when the trigger is preceded by (and followed by) a word delimiter, such as ., ,, or -.
• w:符号边界。这个代码段只有被指定的字符如,,.,-前后包围时才有效。
  Multiple options can be used at once.多个选项可以同时使用。如rm,ma。

Tabstops定位点

• Insert tabstops for the cursor to jump to using $X, where X is a number starting from 0.
  使用$X作为定位点，其中X从0开始。
• Pressing Tab will move the cursor to the next tabstop.
  按下Tab键指针将会移动到下一个定位点
• Tabstops can have placeholders. Use the format ${X:text}, where text is the text that will be selected by the cursor on moving to this tabstop.
  定位点可以有占位符，格式是${X:text}。指针移动到当前定位点时会选中text内容。
• Tabstops with the same number, X, will all be selected at the same time.
  如果多个定位点有相同的编号X，那么将会同时被选中。

Examples

{trigger: "//", replacement: "\\frac{$0}{$1}$2", options: "mA"}
输入'//' ，替换为除法公式。
{trigger: "dint", replacement: "\\int_{${0:0}}^{${1:\\infty}} $2 d${3:x}", options: "mA"}

{trigger: "outp", replacement: "\\ket{${0:\\psi}} \\bra{${0:\\psi}} $1", options: "mA"}

Regex公式

• Use the r option to create a regex snippet.
  使用r选项创建公式代码段
• In the trigger, surround an expression with brackets () to create a capturing group.
  在触发器中，使用括号包住表达式创建一个输入组。
• Inside the replacement string, strings of the form [[X]] will be replaced by matches in increasing order of X, starting from 0.
  在replacement字符串中，格式为[[X]]的字符串将会被触发器输入组中对应顺序的字符替代。

❗ Warnings警告

• Some characters, such as \, +, and ., are special characters in regex. If you want to use these literally, remember to escape them by inserting two backslashes (\\) before them!
  某些字符如 \, +, and .,在公式中是特殊字符。如果要使用这些字符，需要在前面加上转义符\\

Example例子

The snippet代码段

{trigger: "([A-Za-z])(\\d)", replacement: "[[0]]_{[[1]]}", options: "rA"}

详细解释：
触发器中，第一个括号内表明可以输入任何字母，第二个括号表明输入数字。
替换内容表示用第一个字母加_加第二个数字作为替换文本。
这个触发器表示将形如x2的输入变为x_{2},也就是$x_2$

Variables变量

The following variables are available for use in a trigger or replacement:
在触发器和替换内容中可以使用以下变量

• ${VISUAL} : Can be inserted in a replacement. When the snippet is expanded, "$VISUAL"isreplacedwiththecurrentselection.‘${VISUAL} :可以插入替换内容，当代码段展开时，${VISUAL}` 被替换为当前选择内容。
• Visual snippets will not expand unless text is selected.

一些有用的代码段定义

title:进入数学模式

{trigger: "mk", replacement:"$$0$", options: "tA"}

文本模式下输入"mk"进入单行数学模式

{trigger: "dm", replacement: "\$\$\n$0\n\$\$", options: "tAw"},

文本模式下输入"dm"进入多行数学模式

{trigger: "beg", replacement: "\\begin{$0}\n$1\n\\end{$0}", options: "mA"}

文本模式下输入"beg"进入多行数学模式并加入begin和end块

title:罗马字符后面加其他字符
    {trigger: "\\\\(${GREEK}|${SYMBOL})([A-Za-z])", replacement: "\\[[0]] [[1]]", options: "rmA"},
    默认情况下罗马字符后面不加空格就加其他字符会出错,以上代码段自动在罗马字符后加空格。
    {trigger: "\\\\(${GREEK}|${SYMBOL}) sr", replacement: "\\[[0]]^{2}", options: "rmA"},
    罗马字符的平方
    {trigger: "\\\\(${GREEK}|${SYMBOL}) cb", replacement: "\\[[0]]^{3}", options: "rmA"},
    罗马字符的立方
    {trigger: "\\\\(${GREEK}|${SYMBOL}) rd", replacement: "\\[[0]]^{$0}$1", options: "rmA"},
    罗马字符后自动加上n次方括号并把光标移动到括号内
    {trigger: "\\\\(${GREEK}|${SYMBOL}) hat", replacement: "\\hat{\\[[0]]}", options: "rmA"},
    罗马字符上面加戴帽符号
    {trigger: "\\\\(${GREEK}|${SYMBOL}) dot", replacement: "\\dot{\\[[0]]}", options: "rmA"},
    罗马字符上面加点符号
    {trigger: "\\\\(${GREEK}|${SYMBOL}) bar", replacement: "\\bar{\\[[0]]}", options: "rmA"},
    罗马字符上面加平均符号
