如何在 vscode 片段中使用双反斜杠 `\\`

Question

我想让这段代码起作用：

"General matrix": {
    "prefix": "general-matrix-n-n-with-a-elements",
    "body": [
        "\begin{equation}",
        "\t \begin{bmatrix}",
        "\t\t a_{11} & a_{12} & a_{13} & \dots  & a_{1n} \\ ",
        "\t\t a_{21} & a_{22} & a_{23} & \dots  & a_{2n} \\ ",
        "\t\t \vdots & \vdots & \vdots & \ddots & \vdots \\ ",
        "\t\t a_{n1} & a_{n2} & a_{n3} & \dots  & a_{nn}",
        "\t \end{bmatrix}",
        "\end{equation}",
    ],
    "description": "General n by n matrix"

以便它格式化为这个

    \begin{equation}
    \begin{bmatrix}
            a_{11} & a_{12} & a_{13} & \dots  & a_{1n} \
            a_{21} & a_{22} & a_{23} & \dots  & a_{2n} \
            \vdots & \vdots & \vdots & \ddots & \vdots \
            a_{n1} & a_{n2} & a_{n3} & \dots  & a_{nn}
    \end{bmatrix}
    \end{equation}

但是反斜杠的格式是这样的

    \begin{equation}
    \begin{bmatrix}
            a_{11} & a_{12} & a_{13} & \dots  & a_{1n} \ 
            a_{21} & a_{22} & a_{23} & \dots  & a_{2n} \ 
            \vdots & \vdots & \vdots & \ddots & \vdots \ 
            a_{n1} & a_{n2} & a_{n3} & \dots  & a_{nn}
    \end{bmatrix}
    \end{equation}

请注意，行尾没有双 \，而是一个 \

只需再添加两个反斜杠，如：

"General matrix": {
    "prefix": "general-matrix-n-n-with-a-elements",
    "body": [
        "\begin{equation}",
        "\t \begin{bmatrix}",
        "\t\t a_{11} & a_{12} & a_{13} & \dots  & a_{1n} \\\ ",
        "\t\t a_{21} & a_{22} & a_{23} & \dots  & a_{2n} \\\ ",
        "\t\t \vdots & \vdots & \vdots & \ddots & \vdots \\\ ",
        "\t\t a_{n1} & a_{n2} & a_{n3} & \dots  & a_{nn}",
        "\t \end{bmatrix}",
        "\end{equation}",
    ],
    "description": "General n by n matrix"
  }

您要打印的片段中的每个反斜杠都需要 双重转义，因此如果您想要输出 2 个，则每个反斜杠多 2 个，总共 6 个。
