# How to reproduce this box in tcolorbox

I'm working with tcolorbox, I saw the pdf here and I want to reproduce the little green box in this image:

This is a \newtcbox called mylib and defined in tcolorbox.tex:

\documentclass{article}
\usepackage[many]{tcolorbox}

\newtcbox{\mylib}{enhanced,nobeforeafter,tcbox raise base,boxrule=0.4pt,top=0mm,bottom=0mm,
right=0mm,left=4mm,arc=1pt,boxsep=2pt,before upper={\vphantom{dlg}},
colframe=green!50!black,coltext=green!25!black,colback=green!10!white,
overlay={\begin{tcbclipinterior}\fill[green!75!blue!50!white] (frame.south west)
rectangle node[text=white,font=\sffamily\bfseries\tiny,rotate=90] {LIB} ([xshift=4mm]frame.north west);\end{tcbclipinterior}}}

\begin{document}

\mylib{test}

\end{document}


This pice of code also works with the \tikzexternalize flag.

\documentclass{standalone}
\usepackage[usenames,dvipsnames,svgnames,table]{xcolor}
\usepackage{tikz}
\usepackage{lipsum}

\newcommand{\mylib}[1]{
\tikz[baseline=-0.5ex]{
\tikzset{lib/.style={
rectangle split,
rectangle split parts=2,
rectangle split horizontal,
rectangle split part fill={green!75!blue!50!white,green!10!white},
rectangle split draw splits=false,
rounded corners=2pt,
rectangle split part align={right,right},
draw=green!50!black,
minimum height=16pt}
}
\node[lib] (var){
\nodepart[text=green!25!black]{two}#1};
\node[text=white,font=\sffamily\bfseries\tiny,rotate=90] at ([xshift=6pt]var.west) {LIB};
}
}
\begin{document}
\mylib{test}
\mylib{v}
\mylib{longvar}
\end{document}


• Nice solution. A minor detail: In the original, there is no green line between LIB and the library name. – jarauh Nov 13 '15 at 11:52
• To erase line between LIB and library name you just need to add option rectangle split draw splits=false to lib/. style. – Zarko Nov 13 '15 at 12:35
• @Zarko thank you for the hint. I've edited the post. – CDieck Nov 13 '15 at 13:38
