# Automatically creating footnotes when referencing Multimarkdown glossary entries

Multimarkdown has a feature to add glossary entries when compiling to LaTeX, and it looks like this:

[^glossaryentry]: glossary: term
The actual definition belongs on a new line, and can continue on
just as other footnotes.

And to reference a glossary entry created that way, you can use:

This is some text. [^glossaryentry]

Which, in LaTeX, renders to

Unfortunately, `\glsadd` does not add any indication in the text where it is invoked, and there is not (easy) way to change the Multimarkdown behavior to use, `\gls` instead of `\glsadd`, for example.

The workaround I devised for this problem is that I overwrote the `\glsadd` command.

# First: Caveats

1. In my case the created footnote markers (the small numbers added inline) linked to the first page of the document instead of linking to the actual footnote, and I wasn’t able to find out why. I “fixed” this problem by disabling links for footnotes entirely by using the `hyperfootnotes=false` for the `hyperref` package, as explained here.

2. If you want to use LaTeX commands or math mode in your glossary entries you will need to specify the following option for the “glossaries” package:

\usepackage[
...,
sanitize={description=false}
]{glossaries
}

# The Code

% Rewrite glsadd so that it also creates a footnote
% We do this so that the glossary references created by Multimarkdown
% (which uses \glsadd) also generate a footnote (didn’t want to hack mmd)

% This copies the old \glsadd command to \Oldglsadd, so that we can invoke it in our new command
