mdframed theorem environments + \listoftheorems

[andrew-hill]

I'm using mdframed + theorems as per Example 5 in mdframed-example-default.pdf but can't figure out how to generate a list of theorems.

I define my environment as follows

\mdfdefinestyle{examplestyle}{linewidth=2pt,innermargin=1em,outermargin=1em,%
                       skipabove=1em,skipbelow=1em,backgroundcolor=examplebackground,%
                       needspace=8cm%
}
\mdtheorem[style=examplestyle]{example}{Example}[chapter]

Then use it as

\begin{example}[Some trivial example]
        \dots
\end{example}

Previously I had been using the thmtools package and defining my theorem with \newtheoremstyle & \declaretheorem (and making my own environment that called mdframed around the theorem env), which seems to handle some of the registration for \listoftheorems, but when I use the method suggested in the mdframed example document, I get an empty \listoftheorems.

Is there some trick to having mdframed theorems registered in the \listoftheorems?

On a side note, for what it's worth, I'm really impressed by how far mdframed has come since I last used it (over a year ago) when you sent me v0.5 for testing. It's definitely easier to use with theorems, and I really like the look of some of your more advanced examples; I'll definitely be trying those out (:

Hi,

mdframed uses the command \newtheorem to create a theorem environment. If you use the package thmtools or ntheorem you can use \listtheorems.

mdframed seems to call \newtheorem for \newmdtheoremenv, but does not for \mdtheorem — so the list only seems to work for \newmdtheoremenv environments, not \mdtheorem environments — is that intentional?

Hi,

sorry I complety missed this. I uploaded a new version (github). With the new version the following example should work well. Note I didn't support the unnumbered star-version.

\documentclass{article}
\usepackage{xcolor}
\usepackage{amsmath}
\usepackage{ntheorem}
\usepackage{mdframed}
\mdtheorem{lemma}{Lemma}
\newrobustcmd\ExampleText{%
An \textit{inhomogeneous linear} differential equation has the form
\begin{align}
L[v ] = f,
\end{align}
where $L$ is a linear differential operator, $v$ is
the dependent variable, and $f$ is a given non−zero
function of the independent variables alone.
}
\begin{document}
\listtheorems{lemma}
\section{foo}
\begin{lemma}[inhomogeneous linear]
\ExampleText
\end{lemma}
\begin{lemma}[inhomogeneous linear]
\ExampleText
\end{lemma}
\end{document}

I have the impression that including mdtheorems in a \listoftheorems still does not work. I cross-posted this to TeX.SE, but I repeat the code and output here for convenience:

\documentclass{article}
\usepackage{amsthm,thmtools}
\usepackage{mdframed}
\usepackage{xcolor}

\usepackage{mdframed}
\mdfdefinestyle{guidelinestyle}{% 
  linecolor=black,
  linewidth=1pt,
  frametitlerule=true,
  frametitlefont=\sffamily\bfseries,
  frametitlebackgroundcolor=gray!20,
  innertopmargin=\topskip,
} 
% \newmdenv[style=guidelinestyle]{asEnv}{asEnv}[section]
\newmdtheoremenv[style=guidelinestyle]{asTheoremEnv}{asTheoremEnv}[section]
\mdtheorem[style=guidelinestyle]{asTheorem}{asTheorem}[section]

\begin{document}
\expandafter\csname ver@mdframed.sty\endcsname

%\listoftheorems[ignoreall,show=xxx]  % this is how I actually display it in my document
\listoftheorems

\section{My section}

% \begin{asEnv}[As environment, it appears in ToTh]
%   But it doesn't look like what I want.
% \end{asEnv}

\begin{asTheoremEnv}[As theoremEnv, it appears in ToTh]
  But it doesn't look like what I want.
\end{asTheoremEnv}

\begin{asTheorem}[As theorem, it does not appear in ToTh]
 But it looks a lot better!
\end{asTheorem}

\end{document}

As you see, the version included in TeX Live (MacTeX 2015), this issue still exists: the mdtheorem is not included in the table of theorems, the other one is (but doesn't look the same).
