我正在使用algorithmic包来显示代码。为了获得右对齐、左对齐的注释，我还使用了包eqparbox并重新定义\algorithmiccomment；请参见下面的最小示例。
从所附快照中可以看出，除第二条注释外，所有注释都按预期左对齐。我猜应该可以通过重新定义或修补一些命令来解决这个问题algorithmic.sty，但查看该文件后，我无法确定问题的根源。有什么想法吗？
\documentclass{article}
\usepackage{algorithmic}
\usepackage{eqparbox}
\renewcommand{\algorithmiccomment}[1]{\hfill\eqparbox{COMMENT}{\{#1\}}}
\begin{document}
\begin{algorithmic}
\STATE something \COMMENT{first comment}
\IF[second comment]{some condition}
\STATE some other thing \COMMENT{3rd comm}
\STATE final thing \COMMENT{some final thoughts}
\ENDIF
\end{algorithmic}
\end{document}
答案1
此问题已为人所知，请参阅算法包中注释的右对齐错误。
正确的方法是使用algorithmicx(特别是algpseudocode变体) 而不是。如果您想保持代码原样，algorithmic可以使用其选项。compatible
梅威瑟：
\documentclass{article}
\usepackage[compatible]{algpseudocode} % or \usepackage{algcompatible}
\usepackage{eqparbox}
\renewcommand{\algorithmiccomment}[1]{\hfill\eqparbox{COMMENT}{\{#1\}}}
\begin{document}
\begin{algorithmic}
\STATE something \COMMENT{first comment}
\IF[second comment]{some condition}
\STATE some other thing \COMMENT{3rd comm}
\STATE final thing \COMMENT{some final thoughts}
\ENDIF
\end{algorithmic}
\end{document}
输出：

这是修复后的版本algorithmic.sty，请将其保存为fixed-algorithm.sty

答案3
这是一个可能的解决方案，使用tikzpagenodes包和tikzmark库将注释放置在右边距：
\documentclass{article}
\usepackage{algorithmic}
\usepackage{showframe}
\usepackage{eqparbox}
\usepackage{tikzpagenodes}
\usetikzlibrary{tikzmark}
\newcounter{mycomm}
\renewcommand{\algorithmiccomment}[1]{%
\stepcounter{mycomm}%
\tikzmark{start-\themycomm}%
\tikz[remember picture,overlay]
\node[inner sep=0pt,outer sep=0pt,anchor=east]
at (current page text area.east|-{pic cs:start-\themycomm})
{\eqparbox{COMMENT}{\{#1\}}};
}
\begin{document}
\begin{algorithmic}
\STATE something \COMMENT{first comment}
\IF[second comment]{some condition}
\STATE some other thing \COMMENT{third comment}
\IF[fourth comment]{some condition}
\STATE final thing \COMMENT{some final thoughts}
\ENDIF
\ENDIF
\end{algorithmic}
\end{document}
