A Scannerless GLR parser/parser generator. Note that GLR standing for "generalized LR", where L stands for "left-to-right" and
R stands for "rightmost (derivation)". For more information see <https://en.wikipedia.org/wiki/GLR_parser>. This parser is based on the Tomita
(1987) algorithm. (Paper can be found at <https://aclanthology.org/P84-1073.pdf>).
The original 'dparser' package documentation can be found at <https://dparser.sourceforge.net/>. This allows you to add mini-languages to R (like
rxode2's ODE mini-language Wang, Hallow, and James 2015 <DOI:10.1002/psp4.12052>) or to parse other languages like 'NONMEM' to automatically translate
them to R code. To use this in your code, add a LinkingTo dparser in your DESCRIPTION file and instead of using #include <dparse.h> use
#include <dparser.h>. This also provides a R-based port of the make_dparser <https://dparser.sourceforge.net/d/make_dparser.cat> command called
mkdparser(). Additionally you can parse an arbitrary grammar within R using the dparse() function, which works on most OSes and is mainly for grammar
testing. The fastest parsing, of course, occurs at the C level, and is suggested.

dpGetFile function

<dl><dt>file</dt>
<dd>- File to handle. This file can be:<ul>
<li>an actual file.</li>
<li>a character string. In this case, a temporary file is
created with the character string.</li>
<li>A bracket <code><a href="/link/%7B%7D?package=dparser&version=1.3.1-12" data-mini-rdoc="dparser::{}">{}</a></code> enclosed R expression. In this case
the contents of the expressions is put into a temporary file.</li>
<li>A function. In this case the contents of the function body are put into the temporary file.</li>
</ul></dd>
<dt>fileext</dt>
<dd>file extension of temporary file to create</dd>
