How to restart the count of stanza (with reledpar)

Question

I am new to using Latex, and I hope my question is correct. In the context of a critical edition, I need to count the stanzas (if possible in Roman numeral), and the count must restarted at each section. Here is my code :

    \documentclass[12pt,onecolumn,twoside,a4paper]{memoir}
    \usepackage[utf8]{inputenc}
    \usepackage[T1]{fontenc}
    \usepackage[francais,latin]{babel}
    \usepackage{xspace}
    \usepackage{setspace}
    \usepackage{multicol}
    \usepackage{verse}
    %%%%%%%%%%%%%%%%%
    \usepackage[ widthliketwocolumns,

        noeledsec,
        noend,
        nofamiliar,
        noledgroup,
        series={}
        ]{reledmac}
    \usepackage{reledpar}
    %%%%%%%
    \setcounter{stanzaindentsrepetition}{1}
    \setstanzaindents{0,0,0}
    \AtEveryStopStanza{\vspace{1\baselineskip}}
    \numberstanzatrue

    \Columns
    \end{document}

I would also like to know how to include comments in the margin, for each stanza.

Thank you very much for your help

Answer 1

\renewcommand{\thestanzaL}{\textbf{\roman{stanzaL}}} will change the stanza counter for the left column to roman numerals, use \Roman if you want capital letters. You can reset the left column stanza counter with \setcounter{stanzaL}{0} at any point, e.g. at the beginning of every section or subsection. There may be more elegant or automatic ways to do that though that I am not aware of.

The documentations for reledmac (p. 68) and reledpar (p. 22) explain about marginal notes, although I'd suspect your page would become very crowded when setting two columns in parallel and adding notes in either the columns or page margins.
