如何在 vscode 片段中使用双反斜杠`\\`

Question

我想让这个片段工作：

"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

    \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}

但是反斜杠正在格式化为此

    \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，\\行尾不是双数，而是单数\

Answer 1

只需添加两个反斜杠，如下所示：

"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"
  }

您想要打印的片段中的每个反斜杠都需要进行双重转义，因此如果您想要输出 2 个，则每个反斜杠额外增加 2 个，总共 6 个。
