[EP-tech] Re: Citation count plugin


I found the problem, the configuration files of the plugin don't enable 
it anywhere, so I had to add the relevant code manually. More 
specifically, I added:

$c->{plugins}{"Import::CitationService::Scopus"}{params}{disable} = 0;
$c->{plugins}{"Import::CitationService::WoS"}{params}{disable} = 0;
$c->{plugins}{"Import::CitationService::GScholar"}{params}{disable} = 0;

in file archives/myrepo/cfg/cfg.d/datasets_citation-count.pl, after the 
first "use" statement.

The problem now is that after enabling the plugins, I get a new error:

$ ~/lib/epm/citation-count/bin/import_citationdata --verbose myrepo scopus
"my" variable $mesg masks earlier declaration in same scope at (eval 
156) line 114, <DATA> line 751.
Possible attempt to put comments in qw() list at (eval 162) line 18, 
<DATA> line 751.
defined(@array) is deprecated at 
line 46.
     (Maybe you should just omit the defined()?)

I'll try to ask the plugin's maintainer about what to do with this 
error, but any advise is more than welcome!
