[Tex/LaTex] Adding sections such as Linkedin and Github to a Moderncv footer

Question

How do I add extra links to the footer of a moderncv document that are not covered by the default commands?

Answer 1

Here's one way to do it adding to new fields \github and \linkedin; the information will be automatically added to the footer, with hyperlinks and some logos (for the logos I used the images obtained with the code at the end of this answer):

\documentclass[11pt,a4paper,sans]{moderncv}
\moderncvstyle{casual}
\usepackage[scale=0.75]{geometry}

\makeatletter

\newcommand*{\linkedin}[1]{\def\@linkedin{#1}}
\newcommand*{\github}[1]{\def\@github{#1}}
\newcommand*{\externallink}[2][]{%
  \ifthenelse{\equal{#1}{}}%
    {\href{#2}{#2}}%
    {\href{#2}{#1}}}
\newcommand\githublogo{\raisebox{-1pt}{\includegraphics[height=9pt]{github}}\ }
\newcommand\linkedinlogo{\raisebox{-1pt}{\includegraphics[height=9pt]{linkedin}}\ }

\renewcommand*{\makecvfooter}{%
  \setlength{\footerwidth}{0.8\textwidth}%
  \fancypagestyle{plain}{%
    \fancyfoot[c]{%
      \parbox{\footerwidth}{%
        \centering%
        \color{color2}\addressfont%
        \ifthenelse{\isundefined{\@addressstreet}}{}{\addtofooter[]{\addresssymbol\@addressstreet}%
          \ifthenelse{\equal{\@addresscity}{}}{}{\addtofooter[~--~]{\@addresscity}}\flushfooter\@firstfooterelementtrue\\}% if \addresstreet is defined, \addresscity will always be defined but could be empty
        \ifthenelse{\isundefined{\@addressstreettwo}}{}{\addtofooter[]{\addresssymbol\@addressstreettwo}%
          \ifthenelse{\equal{\@addresscitytwo}{}}{}{\addtofooter[~--~]{\@addresscitytwo}}\flushfooter\@firstfooterelementtrue\\}% if \addresstreet is defined, \addresscity will always be defined but could be empty
        \ifthenelse{\isundefined{\@mobile}}{}{\addtofooter{\mobilesymbol\@mobile}}%
        \ifthenelse{\isundefined{\@phone}}{}{\addtofooter{\phonesymbol\@phone}}%
        \ifthenelse{\isundefined{\@fax}}{}{\addtofooter{\faxsymbol\@fax}}%
        \ifthenelse{\isundefined{\@email}}{}{\addtofooter{\emailsymbol\emaillink{\@email}}}%
        \ifthenelse{\isundefined{\@homepage}}{}{\addtofooter{\homepagesymbol\httplink{\@homepage}}}%
        \ifthenelse{\isundefined{\@extrainfo}}{}{\addtofooter{\@extrainfo}}%
        \ifthenelse{\isundefined{\@linkedin}}{}{\addtofooter{\linkedinlogo\externallink{\@linkedin}}}%
        \ifthenelse{\isundefined{\@github}}{}{\addtofooter{\githublogo\externallink{\@github}}}%
        \flushfooter}}}%

  \pagestyle{plain}}


\moderncvcolor{blue}
