在 PdfLatex 中使用 \newcommand 添加分类颜色

在 PdfLatex 中使用 \newcommand 添加分类颜色

我希望有一个预定义的 HTML 颜色代码列表，并将它们转换为可重复使用的编号变量，以便以后引用。当您有一定数量的变量或类别希望内联着色而不必记住定义名称或创建大量定义并\textcolour{colname}{text}每次都输入时，这很有用。

定义：

cols = ['#222','#ffc','#123']

用法：

\c1 {text in firstcolour} and then \c2{text in secondcolour}

答案1

我们可以将计数器与新命令宏结合使用，以便将来生成可以为文本着色的新命令。下面给出了一个简单的示例：

%define colours pre document 

\newcounter{cnt}
\newcommand{\cdef}[1]{%
 \stepcounter{cnt}%
\xglobal \definecolor{#1}{HTML}{#1}
\expandafter\newcommand\csname c\Roman{cnt}\endcsname{\textcolor{#1}}%
}


%start the main body
\begin{document}



% Define list of colours to run here, reference with \cI \cII \cIII etc... 
\cdef{00CCFF}
\cdef{99CC99}


%write away within the document
\cI {test c1} and then \cII{test c2}

这将产生以下内容：

答案2

您可以建立一个以数字为参考的列表：

\documentclass{article}
\usepackage{xparse}
\usepackage{xcolor}

\ExplSyntaxOn
\NewDocumentCommand{\colorlist}{m}
 {
  \clist_map_inline:nn {#1}
   {
    \seq_gput_right:Nn \g_colorlist_list_seq { ##1 }
   }
 }

\NewDocumentCommand{\usecolor}{mm}
 {
  \textcolor[HTML]{ \seq_item:Nn \g_colorlist_list_seq { #1 } } { #2 }
 }

\seq_new:N \g_colorlist_list_seq

\ExplSyntaxOff

\colorlist{828282,FF0000,00FF00}

\begin{document}

\usecolor{1}{text in first color}

\usecolor{2}{text in second color}

\usecolor{3}{text in third color}

\end{document}

注意，xcolor要求 HTML 颜色以字符串形式给出六十六进制数字，大写或小写。

答案3

您请求命令\c。
\cLaTeX 2e 内核已将其定义为传递带有变音符的字母。
因此，在下面的示例中，\ColorNumber改为定义命令。

以下是您自己提供的答案的变体：

\documentclass{article}
\usepackage{xcolor}

\makeatletter

% define colours pre document 

\newcommand\MYNAMESPACEDefinedColorTotal{0}%
\newcommand\cdef[1]{%
 \@bsphack
 \begingroup
 \@tempcnta=\MYNAMESPACEDefinedColorTotal\relax
 \advance\@tempcnta by 1\relax
 \xdef\MYNAMESPACEDefinedColorTotal{\number\@tempcnta}%
 \endgroup
 \xglobal\definecolor{%
   MYNAMESPACEDefinedColor\MYNAMESPACEDefinedColorTotal%
 }{HTML}{#1}%
 \@esphack
}

\newcommand\ColorNumber[1]{\textcolor{MYNAMESPACEDefinedColor#1}}%

\makeatother

%start the main body
\begin{document}

\cdef{00CCFF}
\cdef{99CC99}

%write away within the document
\ColorNumber{1}{test c1} and then \ColorNumber{2}{test c2}


\end{document}

enter image description here

下面是您自己提供的答案的另一种变体，这里\ColorNumber的第一个参数通过参数文本中的 -notation 用花括号分隔#1#- 这更接近您在问题中要求的符号：

\documentclass{article}
\usepackage{xcolor}

\makeatletter

% define colours pre document 

\newcommand\MYNAMESPACEDefinedColorTotal{0}%
\newcommand\cdef[1]{%
 \@bsphack
 \begingroup
 \@tempcnta=\MYNAMESPACEDefinedColorTotal\relax
 \advance\@tempcnta by 1\relax
 \xdef\MYNAMESPACEDefinedColorTotal{\number\@tempcnta}%
 \endgroup
 \xglobal\definecolor{%
   MYNAMESPACEDefinedColor\MYNAMESPACEDefinedColorTotal%
 }{HTML}{#1}%
 \@esphack
}

\newcommand\ColorNumber{}%
\def\ColorNumber#1#{\textcolor{MYNAMESPACEDefinedColor#1}}%

\makeatother

%start the main body
\begin{document}

\cdef{00CCFF}
\cdef{99CC99}

%write away within the document
\ColorNumber1{test c1} and then \ColorNumber2{test c2}


\end{document}

还有另一种变化，其中数字尾部的空格被删除：

\definecolor{xYellow}{HTML}{F7B538} %[0.97 0.71 0.22]
\definecolor{xOrange}{HTML}{EC6D00} %[0.93 0.43 0.00]

\definecolor{xPink}{HTML}{D30580}   %[0.83 0.02 0.51]

然后像这样使用：

\textcolor{xCyan}{cyan}

哦，顺便说一下，给文本上色时，通常以粗体显示效果会更好：

\textcolor{xCyan}{\textbf{cyan}}
