Pending new version of glossaries (v4.47) will be changing the format of the .glsdefs file

[nlct]

As part of a bug fix, the next version of glossaries (v4.47) will have a slightly different syntax in the .glsdefs file. This will affect atom-autocomplete-glossaries.

Example documents:

\documentclass{article}
\usepackage{glossaries}

\begin{document}
\newglossaryentry{test}{name={test},description={sample}}
\gls{test}.
\end{document} 

or with glossaries-extra:

\documentclass{article}
\usepackage[docdef=atom]{glossaries-extra}

\newglossaryentry{test}{name={test},description={sample}}

\begin{document}
\gls{test}.
\end{document} 

Currently (v4.46 and below) this will write the data for each entry in the .glsdefs file as:

\ifglsentryexists{<label>}{}%
{%
\gls@defglossaryentry{<label>}%
{%
<key value list>
}%
}%

The new format will be:

\glsdefs@newdocentry{<label>}%
{%
<key value list>
}% 

This new internal command means that any future modifications will hopefully not require any further changes in the file format.

It will be possible to rollback to v4.46 to retain the old format:

\usepackage{glossaries}[=v4.46]

(but you won't get the benefit of the bug fixes).
