如何制作或添加包或功能的选项

我现在正在使用钢琴套餐。这个包有点受限，所以我想改变一些东西。圆点的标准颜色是橙色。我想在不同情况下改变这一点。但我不想sty每次都编辑文件。我想更改

\keyboard[color = … ]…

或者

\usepackage[color = … ]{piano}

我该如何改变这一点？第一个选项是我的首选选项，但标准代码是“ \keyboard[Dso][Fso][Aso][Dst]”，所以我必须将其更改为\keyboard{Dso}{Fso}{Aso}{Dst}，但我不知道这是否可行……有人能帮我吗？谢谢

通过以下重新定义，\keyboard现在您有一个由括号分隔的可选第一个参数，允许您随意更改颜色：

例如，现在你可以说：

\keyboard[Co][Eo][Gso][Ct][Et]

\keyboard(cyan)[Co][Eo][Gso][Ct][Et]

\keyboard(olive)[Co][Eo][Gso][Ct][Et]

代码：

\documentclass[11pts]{article}
\usepackage{xcolor}
\usepackage{piano}
\usepackage{xparse}

\makeatletter
\RenewDocumentCommand{\keyboard}{D(){orange}O{0}O{0}O{0}O{0}O{0}O{0}O{0}}{

不建议改变参数的输入方式，方括号表示法更好，因为七个参数是可选的。

要改变颜色，最简单的方法是加载xcolor并改变定义orange：

\documentclass{article}
\usepackage{piano}
\usepackage{xcolor}
\colorlet{orange}{red!20}
\begin{document}
  \keyboard[Co][Eo][Gso][Ct][Et]
\end{document}

该\colorlet命令在本地起作用，因此您可以在某些环境或组中更改颜色，以免破坏默认颜色。

现在您可以使用键值语法输入键盘：

\documentclass{article}
\usepackage{xpiano}
\begin{document}
\keyboard{
  color=red!20,
  one=Co,
  two=Eo,
  three=Gso,
  four=Ct,
  five=Et
}

\bigskip

\keyboard{
  one=Cso,
  two=Fso,
}

\end{document}

允许的键color用于设置颜色和one two three four five six seven标记键；值color必须是语法中的颜色名称xcolor，可以是预定义的，也可以是像示例中那样给定的色调。

您还可以通过重新定义来全局更改默认颜色pianodefault，例如

\definecolor{pianodefault}{RGB}{255,0,0}

或者

\colorlet{pianodefault}{red}

将红色作为默认颜色。

答案3

该piano.sty包定义了所有点的颜色orange。如果您重新定义颜色orange，则可以更改插入的每个键盘的外观。不过，我不确定如何更改每个点的颜色……

\documentclass{minimal}
\usepackage{piano}

\begin{document}

% red dots
\definecolor{orange}{RGB}{255,0,0}
\keyboard[Co][Eo][Gso][Ct][Et]

% green dots
\definecolor{orange}{RGB}{0,127,0}
\keyboard[Co][Eo][Gso][Ct][Et]

% blue dots
\definecolor{orange}{RGB}{0,0,255}
\keyboard[Co][Eo][Gso][Ct][Et]

\end{document}
