Re: [EP-underground] enabling latex features

Thanks very much for your reply.  I had a hard time getting convert to work properly but I now get proper mathematical output when I go to 
http://--archiveurl--/perl/latex2png?latex={\pi}r^2

However, I cannot find the file ArchiveMetadataConfig.pm.  Where is it supposed to be?  I did a 
     find . - name ArchiveMetadataConfig.pm 
in the highest eprints directory but nothing shows up.

I did find a file ArchiveMetadataFieldsConfig.pm.  Is that the one?  But I could not figure out where to put the line 
  render_single_value => \&EPrints::Latex::render_string 

Any help will be appreciated.  Thank you.

First you should check it's working... try

http://--archiveurl--/perl/latex2png?latex={\pi}r^2

Which should return the image of an equation.

The most likely problem you'll have is it not knowing where latex/convert etc.
are, in which case edit /opt/eprints2/perl_lib/EPrints/SystemSettings.pm

THEN:

In ArchiveMetadataConfig.pm add the following property to the text or
longtext field(s):

render_single_value => \&EPrints::Latex::render_string 

This overrides the default field renderer with the latex aware one.
