Re: [EP-tech] EPScript - Author Limit


Hi David,

I'm very jealous; that's exactly what I'm going for, even the clickable "et al" (I thought I might have had an original idea up until I saw that).

Any guidance you can give me would be brilliant. I may hold off jumping in and editing that file for the time being and do some more investigating.

Thanks,
James

Hi James,

This is what I did for one of the repository I help maintain: 

http://researchonline.ljmu.ac.uk/7570/

I should be able to share the code if I can extract it from the rest of
the codebase, as it requires edits to 3-4 files, if I remember
correctly.  Also, if you have other features like people_with_orcids
that modifies the list of authors in the citation in some way (i.e. in
this case add little ORCID buttons to click), then it may require a bit
more of an effort to merge.

Regards

David Newman
