LaTex format to invalid style

[tc1989tc]

As I've shared below, the latex format is not correct.

Latex code

\author[1]{Kai \snm{Zhao}\corref{cor1}}
\author[1]{Haoxin \snm{Zheng}\fnref{fn1}}
\author[1]{Alex Ling-Yu \snm{Hung}}
\author[1]{Ran \snm{Yan}\fnref{fn1}}
\author[1]{Steven S \snm{Raman}}
\author[1]{Holden \snm{Wu}}
\author[1]{KyungHyun \snm{Sung}}

after formated, it display as(this not correct):

\author{[}
1]{Kai \snm{Zhao}\corref{cor1}}
\author{[}
1]{Haoxin \snm{Zheng}\fnref{fn1}}
\author{[}
1]{Alex Ling-Yu \snm{Hung}}
\author{[}
1]{Ran \snm{Yan}\fnref{fn1}}
\author{[}
1]{Steven S \snm{Raman}}
\author{[}
1]{Holden \snm{Wu}}
\author{[}
1]{KyungHyun \snm{Sung}}

What package are you using \author from? It appears that the default \author defined by LaTeX only takes one argument.

It's the \author command from the elsarticle document class.

I see. I will add a elsarticle to unified-latex-ctan/package when I am able. (Or, if you wanted to try, a PR is welcome :-). You can look at multicol for a simple example.

@siefkenj The amsart has included the \author source code link , why parse still as one argument?

[siefkenj]

Yes, but the amsart version of \author accepts only one argument, which is why we need to define another.

[tc1989tc]

Yes, but the amsart version of \author accepts only one argument, which is why we need to define another.

The amsart define \author as signature: "o m", this means an option argument and a mandatory argument. Shouldn't it be receiving two parameters? @siefkenj

[siefkenj]

Oh, I see. The change has already been made!

Yes, it should receive an optional argument. Are you using the git version or the release version? That change might not be released yet.

I use npm release version

@siefkenj The npm latest version did not include the change. Please release the new version to include the commits, thanks!

I just published v1.8.0. Please try it and see if the issue is resolved.

[tc1989tc]

I tested on v1.8.0, it fixes the issue. thanks!
