indexing with eledmac and eledpar

Question

Using eledmac and eledpar for typesetting a critical edition, I wanted to make a splitted index with the \edindex[]{} command. Although I think, that packages are loaded in the correct order and the syntax of \edindex is correct, latex returns the folowing error message:

./test2.tex:36: Undefined control sequence.`
<argument> \string \indexentry {\@index@txt 
                                            \@edindex@hyperref }{\thepageline }
l.36 ...iae Iovis\edindex[persons]{Manubiae Iovis}
                                                   tres creduntur esse, quar...

The following MWE produces this error. I'd be grateful for any hint on whats wrong with the source.

Answer 1

As @Andrew Swann said, it was a bug in eledmac. I have just published on CTAN a correction for these three bugs.

Thanks a lot @Andre Swann and @mxordn.

Answer 2

I think some bugs have crept in to the latest version of eledmac (eledmac 2014/08/15 v1.12.3). In any case, the error you found disappears if you load the hyperref package. However, one then gets a new error caused by index entries containing spaces. This is correctable by writing an extra pair of brackets

 \edindex[persons]{{Manubiae Iovis}}

but that is surely not the intended behaviour (the error comes from the xstring parsing used by the package). Finally even with these two points accounted for, makeindex will now reject three of the four entries in the persons index on the second run. I think you should be report this to the maintainers.
