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

enter image description here

Can anyone help me please?


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


\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}},
  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}}}




enter image description here

  • Actually, its definition in the file tcolorbox.doc.s_main.sty of the package files (downloaded from CTAN), at line 243. I've been searching it too, thanks for the answer !

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


            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},
            minimum height=16pt}
        \node[lib] (var){
        \node[text=white,font=\sffamily\bfseries\tiny,rotate=90] at ([xshift=6pt]var.west) {LIB};

enter image description here

  • Nice solution. A minor detail: In the original, there is no green line between LIB and the library name.

  • To erase line between LIB and library name you just need to add option rectangle split draw splits=false to lib/. style.
