TOML 表的 blogdown 缩进 - 特别是默认的“config.toml”文件

Question

[params]
    description = "A website built through Hugo and blogdown."

    # options for highlight.js (version, additional languages, and theme)
    highlightjsVersion = "9.12.0"
    highlightjsCDN = "//cdnjs.cloudflare.com/ajax/libs"
    highlightjsLang = ["r", "yaml"]
    highlightjsTheme = "github"

    MathJaxCDN = "//cdnjs.cloudflare.com/ajax/libs"
    MathJaxVersion = "2.7.5"

    [params.logo]  # why is this indented?
    url = "logo.png"
    width = 50
    height = 50
    alt = "Logo"

默认 hugo-lithium 主题的 blogdown 默认 config.toml 文件的结尾如上所示。我对 [params.logo] table 文件末尾五行的缩进感到困惑。

这个 [params.logo] table 不应该是非缩进的吗？为什么我要缩进 [params.logo] table？是不是因为它是子集，属于 [params] table?

我在blogdown的书中找不到解释，尽管它可能在那里但我错过了。我无法想象默认文件是错误的。

    MathJaxCDN = "//cdnjs.cloudflare.com/ajax/libs"

[params.logo]  # shouldn't it be non-indented?
    url = "logo.png"
    width = 50
    height = 50
    alt = "Logo"

Answer 1

缩进无关紧要 - 请参阅 the toml spec

在这种情况下，它作为 reader 的视觉线索是有意义的。 params.logo 是 "under" 参数 - 键 logo 被分配了 table 作为值。
