Exsheets: how do I print the 'solutions' on the same line?

Question

I want to print (dump) the solutions to questions at the end of the book. If I just use \printsolutions I get every solution on a new line (as a new paragraph).

I need to have them on the same line (only numbers, no names), Something like this:

1) Sol one. 2) Sol two. 3) ... etc.

Is there a way/workaround to accomplish this?

If yes, is there a way to automatically include the section/subsection name in the list (on the same line)? Like: ¨

Section 1. Subsection one. 1) Sol one. 2) Sol two. Subsection two. 1) Sol one. 2) Sol two. Section 2. Subsection 1. 1) Sol one ...

Edit:

Following cgnieder Edit I'm trying to find a way to avoid manual labeling and '\nameref'. I came up with something but it's not working as it should - 'printsolutions' gives the same name for sections. Please see the inline text and comments as well. Help!

\documentclass{scrartcl}
\usepackage{exsheets}
\setlength{\parindent}{0pt}

\DeclareQuestionProperty{section-title}
\SetupExSheets{counter-within=section ,
         headings=inline-nr ,
         counter-format=qu)}

\newcommand{\lsection}[1]{
\def\secName{#1}
\section{#1}
}
\SetupExSheets{section-hook = \noindent\bfseries
Section \GetQuestionProperty{section-title}{\CurrentQuestionID}
\space}


\begin{document}

\lsection{One}
\begin{question}
\SetQuestionProperties{section-title= \secName } 
foo
\end{question}
\begin{solution}
foo
\end{solution}

\begin{question}
\SetQuestionProperties{section-title= \secName }
bar
\end{question}
\begin{solution}
bar
\end{solution}

Solutions for section "\secName" are: \printsolutions[section]\\ % OK
ALL the solutions until here are: \printsolutions % OK

\lsection{Two}

\begin{question}
\SetQuestionProperties{section-title= \secName }
baz
\end{question}
\begin{solution}
 baz
\end{solution}

\begin{question}
\SetQuestionProperties{section-title= \secName }
foobar
\end{question}
\begin{solution}
foobar
\end{solution}

Solutions for section "\secName" are: \printsolutions[section]\\ % OK
ALL the solutions at this point are wrong, the 1st section name is "Two" instead of "One": \printsolutions % WRONG!!

\lsection{Answers} %changing '\lsection' to '\section' makes all the section names as "Two" 
This is the output of 'printsolutions' wrongly showing the same section name throuhout (the last name used):
\printsolutions

\end{document}

Answer 1

The list you want is possible using the inline-nr headings instance and with setting \exsheets_par: equal to \scan_stop:. The second point prevents exsheets from a) inserting a \par after its environments and b) inserting vertical space after the \par. This is an undocumented feature but built-in extra for this purpose. I'll add an official user interface for it.

Unfortunately there is currently no way to get the complete list automatically with section titles inserted at the appropriate places. But you can use exsheets' \exlabel mechanism maybe together with nameref for a semi-automatic solution:

\documentclass{scrartcl}
\usepackage[load-headings]{exsheets}
\SetupExSheets{counter-within=section}

\usepackage{nameref}

% place \label and \exlabel simultaneously:
\newcommand*\mylabel[1]{\label{#1}\exlabel{#1}}

\begin{document}

\section{One}\mylabel{sec:foo}
\begin{question}
  foo
\end{question}
\begin{solution}
  foo
\end{solution}

\begin{question}
  bar
\end{question}
\begin{solution}
  bar
\end{solution}

\section{Two}\mylabel{sec:bar}
\begin{question}
  baz
\end{question}
\begin{solution}
  baz
\end{solution}

\begin{question}
  foobar
\end{question}
\begin{solution}
  foobar
\end{solution}

\section{Solutions}
\ExplSyntaxOn
\cs_set_eq:NN \exsheets_par: \scan_stop:
\ExplSyntaxOff
\SetupExSheets{headings=inline-nr,counter-format=qu)}

\textbf{Section \nameref{sec:foo}} \printsolutions[section={\S{sec:foo}}]
\textbf{Section \nameref{sec:bar}} \printsolutions[section={\S{sec:bar}}]

\end{document}

Edit

With version 0.13 (2014/05/11) exsheets provides the option section-hook. In a combination with nameref and question properties it can be used in the following way to achieve the same layout with only one call of \printsolutions:

\documentclass{scrartcl}
\usepackage[load-headings]{exsheets}[2014/05/11]
\SetupExSheets{counter-within=section}
\DeclareQuestionProperty{section-title}
\usepackage{nameref}

\begin{document}

\section{One}\label{sec:foo}
\begin{question}
  \SetQuestionProperties{section-title=\nameref{sec:foo}}
  foo
\end{question}
\begin{solution}
  foo
\end{solution}

\begin{question}
  \SetQuestionProperties{section-title=\nameref{sec:foo}}
  bar
\end{question}
\begin{solution}
  bar
\end{solution}

\section{Two}\label{sec:bar}
\begin{question}
  \SetQuestionProperties{section-title=\nameref{sec:bar}}
  baz
\end{question}
\begin{solution}
  baz
\end{solution}

\begin{question}
  \SetQuestionProperties{section-title=\nameref{sec:bar}}
  foobar
\end{question}
\begin{solution}
  foobar
\end{solution}

\section{Solutions}

\SetupExSheets{
  headings = inline-nr , % numbered and inline
  counter-format = qu) , % numbers 1) 2) ... 
  section-hook =         % code to be added before solutions of a new section
                         % are printed
    % \par begin a new paragraph for a new section
    \noindent\bfseries
    Section \GetQuestionProperty{section-title}{\CurrentQuestionID}%
    \space
}

\printsolutions

\end{document}
