Provide options that let the user set independently the spaces between upper and lower text, respectively, to the separation line

[dbitouze]

Currently, middle sets the same space between upper and lower text to the separation line. It would be useful to provide options such as:

• upper middle,
• lower middle,

that let the user set independently the spaces between upper and lower text, respectively, to the separation line.

I will put this on my ToDo list, but I cannot promise to implement it (soon), because I think it provokes changes at possibly many places (with possible new side effects).

Thanks!

but I cannot promise to implement it (soon), because I think it provokes changes at possibly many places (with possible new side effects).

I don't understand why: if upper middle and lower middle are by default both equal to middle, no change should be provoked, isn't it?

BTW, let me provide a use case. In the following MCE, if the options top and middle are not set (equal to the minimum height of the nodes), the content of the upper and lower part of the tcblisting is likely to overlap these nodes. But the vertical space at the bottom of the upper part would be better not so big.

\documentclass{article}
\usepackage{tcolorbox}

\tcbuselibrary{listings,skins}

\begin{document}
\begin{tcblisting}{%
    sharp corners,
    skin=bicolor,
    top=0.5cm,
    middle=0.5cm,
    overlay={
      \node[minimum width=1cm,minimum height=0.5cm,outer sep=auto,
      anchor=north east,fill=white] at (interior.north east)
      {\itshape\small code};
      \node[minimum width=1cm,minimum height=0.5cm,outer sep=auto,
      anchor=north east,fill=white] at ([yshift=.1mm]segmentation.east)
      {\itshape\small result};
    }
  }
Foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foooo
foo foo foo foo foo foo foo foo foo foo foo foo foo foo foo foooo
\end{tcblisting}
\end{document}

(BTW, the [yshift=.1mm] is the above code (thanks @muzimuzhi!), is discussed in this question.)

Finally a new issue is opened, see #166. Sorry I was a bit lazy for the past 1-2 weeks.

You're very welcome 😄 I hesitated to open an issue myself, not being sure of the status of this phenomenon (and that's why I first asked on TeX.SE).
