![TeXstudio 无法识别“widetext”](https://linux22.com/image/335543/TeXstudio%20%E6%97%A0%E6%B3%95%E8%AF%86%E5%88%AB%E2%80%9Cwidetext%E2%80%9D.png)
我在 TeXstudio 中使用“revtex4-1”文档类。但我发现,即使我在配置的“完成”中选中了术语“revtex4-1.cwl”前的复选框,环境“widetext”仍被标记为“命令无法识别”。
问题是:如何让 TeXstudio 识别“widetext”?
答案1
从常见问题解答:为什么 TeXstudio 将命令标记为无法识别:
TXS 检查文档中的所有 LaTeX 命令是否有效。这可以帮助您在输入时识别错误(拼写错误和未加载的包)。如果命令被标记为无法识别,则 TXS 未找到该命令的定义。请参阅TXS 如何知道有效命令?更多细节。

答案2
widetext.sty 的用法:
\usepackage{widetext}
\setlength\stripsep{3pt plus 1pt minus 1pt}
将以下内容保存为widetext.sty,并将其放在与.tex文件同一目录中
%%---------------------------------------------------
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{widetext}
%% Mimics the widetext environment of revtex4 for any other class package
%% Eg: article.cls
%%
%% Compiled by: Anjishnu Sarkar
%%
%% Advantages:
%% *) Supports float (eg: figure) in two column format (Advantage over
%% multicol package)
%% *) One and twocolumn exist on the same page
%% *) Flow of text shown via rule
%% *) Equal height of text when in two column format
%%
%% Acknowledgment(s):
%% 1. Instead of re-inventing the wheel, two packages (flushend, cuted) of
%% the sttools bundle are used. The sttools bundle is available from CTAN.
%% Lisence of these packages rests with their corresponding author.
%% Any bug/problem with flushend and cuted should be forwarded to their
%% corresponding package authors.
%% 2. The idea of the rule came from the following latex community website
%% http://www.latex-community.org/forum/viewtopic.php?f=5&t=2770
%%
%% This package just defines the widetext environment and the rules.
%%
%% Usage:
%% \documentclass[a4paper,12pt,twocolumn]{article}
%% \usepackage{widetext}
%%
%% \begin{document}
%%
%% Some text in twocolumn
%%
%% \begin{widetext}
%% Text in onecolumn format.
%% \end{widetext}
%%
%% Some more text in twocolumn
%%
%% \end{document}
