# Hanging indents with a Pandoc bibliography

I'm using Pandoc / Markdown / LaTeX to write lab reports.

I've opted to not deal with multiple intermediate files for my bibliography. So I have to use this to generate my documents:

pandoc --csl=apa.csl lab02.md --bibliography=bibtex.bib -o lab02.pdf


This works alright. The issue is that hanging indent does not work. It's easy to solve this through this code block:

\begingroup
# References
\setlength{\parindent}{-0.2in}
\setlength{\leftskip}{0.2in}
\setlength{\parskip}{8pt}

<div id="refs"></div>
\endgroup


Which is how I am citing references. I have to do this because I have a required section after references, otherwise I could simply do # References and have it automatically put everything in, and just do that setlength stuff once right at the end of the doc.

My question is concerning how to create a custom command to do this faster, because I like hanging indent in some other sections too. I want do do this both for ease of use and to learn how to make commands. I am having trouble doing this on my own.

Ideally it'd be something like: \starthang which maps to

\begingroup
# References
\setlength{\parindent}{-0.2in}
\setlength{\leftskip}{0.2in}
\setlength{\parskip}{8pt}


And

\endhang which just is an alias for \endgroup

The best I have come up with is this, which doesn't seem to work:

\newenvironment{hang}
{   {\begingroup
\setlength{\parindent}{-0.2in}
\setlength{\leftskip}{0.2in}
\setlength{\parskip}{8pt}
}
{
\endgroup
}
}


Any ideas greatly appreciated.

One easy solution is to use the hangparas environment from the hanging package:
