hyperref - \autoref：小空格作为分隔符

Question

\autoref{eq:speed}类似输出的命令Equation~1。即，公式和数字之间有一个空格（我猜是受保护的空格）。如何将其更改为例如小空格？

Answer 1

~（或\nobreakspace）用于将“\autoref名称”与其编号联系起来。如果您希望全局更改 以\autoref始终使用（例如）\space，则可以添加

\usepackage{letltxmacro}
\let\oldautoref\autoref
\DeclareRobustCommand{\autoref}[1]{{\let\nobreakspace\space\oldautoref{#1}}}

到你的序言。这将更新\nobreakspace为\space仅供使用\autoref。

\documentclass{article}

\usepackage{hyperref}
\usepackage{letltxmacro}% https://tex.stackexchange.com/q/88001/5764

Here is an equation:
\begin{equation}
  f(x) = ax^2 + bx + c \label{eq:eqn}
\end{equation}
