您好，我想比較兩個逗號分隔的清單。
\documentclass[a4paper]{article}
\usepackage{comment}
\usepackage{ifthen}
\usepackage{xargs}
\usepackage{xkeyval}
\usepackage{xfor}
\begin{document}
\dosomething{\compilation} % compilation is comma separated text coming from the terminal (pdflatex "\def\compilation{cat,vat,rat,sat} \input{myfile.tex}")
%arguments of the new command is another comma separated list I can Print this with #1
\newcommand{\chapterInput}[4][all]{%
%code to compare starts here
\newtoks\myValue
\myValue={#1}
begin{comment}
I wanted to do somthing like this
for(every elemnet in compilation)
{for(every element in myValue)
{\ifthenelse{\equal{elemnet in compilation}{every element in myValue}}
{
\chapter{#3\label{#4}}
\input{#2}
}
{\relax}
}}
end{comment}
%My approach is
\makeatletter
\@for\@myarg:=\myValue\do
{
\@for\@myVar:=\compilation\do
{
\ifthenelse
{
\equal{\@myarg}{\@myVar}
{
\chapter{#3\label{#4}} \input{#2}
}
{\relax}
}
}
}
\newcommand{\sectionInput}[4][all]{%
\section{#3\label{#4}}
\input{#2}
}
\newcommand{\subsectionInput}[4][all]{%
}
\chapterInput[rat,cat]{testChapter}{Test Chapter}{chap:testChapter}
\sectionInput[mat,sat]{testSection}{Test Section}{sect:testSection}
\subsectionInput[bat]{testSection}{A subsection on best}{subsect:testSubsection}
\subsectionInput[vat]{testSection}{This ia a subsection on grain}{subsect:testSubsection}
\end{document}
我的方法行不通。我的做法有問題嗎？任何其他解決方案也將不勝感激。
答案1
每次我閱讀逗號分隔的清單時，我都會得到關聯l3clist。下面的建議使用l3clist.我對程式碼進行了評論，看看會發生什麼。
基本思想是命令的定義\LevelInput，其語法如下：
\LevelInput*{level}[comma list]{file name}{level title}{label}
星號和逗號清單是可選的。如果您使用星號，則使用該關卡的星號版本。基於這個主要功能我定義了\sectionInput。\chapterInput被評論是因為它不適用於article.:
\NewDocumentCommand \sectionInput { s }
{
\IfBooleanTF { #1 }
{
\LevelInput*{section}
}
{
\LevelInput{section}
}
}
主代碼中也應提供預先定義的逗號清單。因此該命令\ProvideDocumentCommand是合適的。僅當命令未定義時它才定義該命令。
經過這個小介紹之後，mwe。
