How to keep both emails in the footer on the same line?

Question

When I increase the scales to left=4cm, right=3cm, the second email in the footer goes to the next line. So, with the same scales as in the following letter template, how can I keep both emails in the footer on the same line, that is, how to prevent the second email from going the next line.

\documentclass[11pt,a4paper,sans]{moderncv}      
\moderncvstyle{casual}  
\moderncvcolor{blue}                               
\usepackage[utf8]{inputenc}                      
\usepackage[scale=0.95, top=1cm, bottom=2cm, left=4cm, right=3cm]{geometry}
\renewcommand*{\addressfont}{\small\mdseries}

\title{Resumé title}                             
\address{36 Mauniour, Valybir, Alcansa}{}{United States}
\phone[mobile]{+19193433283}

Answer 1

Well, one possibility is to change the defined width for the footer (0.8\textwidth) to be a little bit longer.

In moderncvfooti.sty you will find the definition

% lengths
\@initializelength{\footwidth}%
\renewcommand*{\recomputefootlengths}{%
  \setlength{\footwidth}{0.8\textwidth}} 

Add the following code to your preambel with a changed width:

\renewcommand*{\recomputefootlengths}{%
  \setlength{\footwidth}{0.85\textwidth}} % original: 0.8\textwidth

With the following MWE

\documentclass[11pt,a4paper,sans]{moderncv}

% moderncv themes
\moderncvstyle{casual}
\moderncvcolor{blue}

% character encoding
\usepackage[utf8]{inputenc}

% adjust the page margins
\usepackage[scale=0.95, top=1cm, bottom=2cm, left=4cm, right=3cm,showframe]{geometry} % left=4cm, right=3cm  left=2cm, right=1cm

\usepackage{blindtext} % to generate dummy text <===========================

%\setlength{\hintscolumnwidth}{3cm}
%\setlength{\makecvtitlenamewidth}{10cm}

% lengths
%\@initializelength{\footwidth}%
\renewcommand*{\recomputefootlengths}{% <======================================
  \setlength{\footwidth}{0.85\textwidth}} % original: 0.8\textwidth <==========


\renewcommand*{\addressfont}{\small\mdseries}
% personal data
\name{John}{Templeton}
\title{Resumé title}                               % optional, remove / comment the line if not wanted
\address{36 Mauniour, Valybir, Alcansa}{}{United States}% optional, remove / comment the line if not wanted; the "postcode city" and and "country" arguments can be omitted or provided empty
\phone[mobile]{+19193433283}                   % optional, remove / comment the line if not wanted
\email{[email protected]}    
\extrainfo{\emailsymbol\emaillink{r\[email protected]}}

\newlength{\currentparskip}

\opening{To whom it may concern,}
\closing{Yours sincerely,\vspace{-0.5cm}}
\makelettertitle
\setlength{\currentparskip}{\parskip}% save the value of paragraph spacing

    \setlength{\parskip}{\currentparskip}% restore the value    


The body of the letter

\blindtext

\vspace{0.5cm}

\enclosure [\upshape Attached]{\upshape resume, writing sample.}


\makeletterclosing

\clearpage

\end{document}

you get the result:

In version 1.3.0 of moderncvare the footer for cv (command \makecvfooter) and letter (\makeletterfooter) defined in file moderncvstylecasual.sty.

To change command \makeletterfooter you can use the following code:

\patchcmd{\makeletterfooter}{\setlength{\footerwidth}{0.8\textwidth}}{\setlength{\footerwidth}{0.85\textwidth}}{}{} % <==========

((And if you need it to change command \makecvfooter:

\patchcmd{\makecvfooter}{\setlength{\footerwidth}{0.8\textwidth}}{\setlength{\footerwidth}{0.85\textwidth}}{}{} % <==========

With the following MWE only for the usage with version 1.3.0
