![algorithmicx 软件包因行号问题而堵塞](https://linux22.com/image/299204/algorithmicx%20%E8%BD%AF%E4%BB%B6%E5%8C%85%E5%9B%A0%E8%A1%8C%E5%8F%B7%E9%97%AE%E9%A2%98%E8%80%8C%E5%A0%B5%E5%A1%9E.png)
我正在尝试根据这个答案编译代码:https://tex.stackexchange.com/a/1376/35161
我不断收到以下错误:
! Undefined control sequence.
\ALG@cmd@2@alglinenumber ...size \addfontfeatures
{Colour=888888,Numbers=Mon...
l.22 \Function
{Distance}{$x, y$}
?
当我删除行号(更改\begin{algorithmic}[1]
为\begin{algorithmic}
)时,它会编译。有什么线索可以解决这个问题吗?
以下是 MWE:
\documentclass[11pt]{article}
\usepackage{algorithm}
\usepackage{algorithmicx}
\usepackage[noend]{algpseudocode}
\newcommand*\DNA{\textsc{dna}~}
\newcommand*\Let[2]{\State #1 $\gets$ #2}
\algrenewcommand\alglinenumber[1]{
{\sf\footnotesize\addfontfeatures{Colour=888888,Numbers=Monospaced}#1}}
\algrenewcommand\algorithmicrequire{\textbf{Precondition:}}
\algrenewcommand\algorithmicensure{\textbf{Postcondition:}}
\begin{document}
\begin{algorithm}
\caption{Counting mismatches between two packed \DNA strings
\label{alg:packed-dna-hamming}}
\begin{algorithmic}[1]
\Require{$x$ and $y$ are packed DNA strings of equal length $n$}
\Statex
\Function{Distance}{$x, y$}
\Let{$z$}{$x \oplus y$} \Comment{$\oplus$: bitwise exclusive-or}
\Let{$\delta$}{$0$}
\For{$i \gets 1 \textrm{ to } n$}
\If{$z_i \neq 0$}
\Let{$\delta$}{$\delta + 1$}
\EndIf
\EndFor
\State \Return{$\delta$}
\EndFunction
\end{algorithmic}
\end{algorithm}
\end{document}
如果有人发现相关内容,我在 Windows 7 上使用 MikTeX。
答案1
您错过了\usepackage{fontspec} \setmainfont{Hoefler Text}
该链接的前言部分。虽然我的系统上没有该字体,但如果我用已有的字体替换,则在 Windows 7 上使用 TL2014 时不会出现任何错误。这需要 XeLaTeX 或 LuaLaTeX 进行编译。
