将缩进设置为 `0em`，使用换行符时，仍然会有一个空格大小的缩进

将缩进设置为 `0em`，使用换行符时，仍然会有一个空格大小的缩进

问题描述

我对 *TeX 还很陌生，但我将一些\newcommands 定义为某种段落样式（可能不是正确的方法，也许有人可以告诉我如何更好地做到这一点）。

我想要默认的段落样式，没有缩进，段后空格应为 0.08 英寸，段前空格应为 0 英寸。但是，任何段落样式都可以更改这些设置中的任何一个，甚至更多（例如字符样式，例如粗体、斜体、下划线等）。

现在，有时我想插入特定段落样式的段落没有段落后面留空。为此我使用换行符 ( \\)，这通常可以完成工作。但是，对于\paragraphStyle下面的代码，这却不适用。

似乎在第一段中，有一个空格大小的缩进，无论我做什么，都无法消除它。

我尝试过的

我尝试以多种不同的组合来使用\noindent和。\setlength{\parindent}{0em}

正如 Marcel 指出的那样，您的输入中有一个多余的空格。您可以按照 Marcel 的建议删除该空格，或者您可以添加\ignorespaces，在你的宏定义中，对于 的论证\textbf，在 之前#1。另外， 没有必要\textbf{}放在它自己的括号中，所以我把它删掉了。

注意：现在定义的那部分\textbf{\ignorespaces#1}也可以替换为{\bfseries#1}。这里，括号现在是限制范围所必需的，但\ignorespaces不再是必需的因为会将您置于垂直模式，因此会忽略\bfseries中的前导空格，而会将您置于水平模式，其中前导空格很重要#1\textbf{}。

此外，我重新组织了您的定义，\paragraphStyle使其更易于人们阅读。请注意%行尾分隔符的存在，以避免再次出现同样的问题。

“缩进一个空格的大小”实际上并不是缩进，而是行首的一个空格：

看着

    This is wrong:

    \paragraphStyle{
        First line\\
        Second line
    }

后面的换行符\paragraphStyle{被转换为空格，从而导致观察到的“缩进”。您可以通过添加注释%来注释换行符，从而抑制空格，从而避免这种情况：

    This is wrong:

    \paragraphStyle{%
        First line\\
        Second line
    }

您应该使用分组来隔离字体和行距的更改，这样您就不必事后恢复它们。但是，由于必须进行这些更改，因此您需要结束前一个段落（如果尚未完成），并且还要在特殊设置的末尾结束一个段落，以免影响后面的段落。
