Conditional content in moderncv

Question

I am using the package moderncv. I implemented already a conditional statement in the preamble:

\usepackage{ifthen}
\newif\ifresume
\resumetrue %true for RESUME, false for CV

This allows me to set up different designs for either generation of a resume or a cv based on the same data. What I would like to do now, is to also to implement this condition in the

\cventry{year--year}{Degree}{Institution}{City}{Grade}{Description}

data fields in the following sense:

\cventry{year--year}{Degree}{Institution}{City}{Grade}{(short) Description for resume}{(long) Description for CV}

I already tried various ideas to implement this, but none succeeded. The obvious solution would be

\cventry{year--year}{Degree}{Institution}{City}{Grade}{\ifresume
%Text for RESUME
\else
%Text for CV
\fi}

but that does not appear very pracicable.#

Any ideas how to solve this smoothly?

Cheers, Mil

Consider using a combination of expl3 and xparse:

Note that, since it's keyval-based markup, you can explicitly set resume-mode for any single item (or group of items, if you do { \ResumeMode[true] \CVEntry{…} \CVEntry{…} … }).

\documentclass{moderncv}
\usepackage{expl3,xparse}
\ExplSyntaxOn
\keys_define:nn { mil / resume } { % from `expl3`
  start        .tl_set:N   = \l_mil_resume_start_tl,
  end          .tl_set:N   = \l_mil_resume_end_tl,
  degree       .tl_set:N   = \l_mil_resume_degree_tl,
  institution  .tl_set:N   = \l_mil_resume_institution_tl,
  city         .tl_set:N   = \l_mil_resume_city_tl,
  grade        .tl_set:N   = \l_mil_resume_grade_tl,
  resume-text  .tl_set:N   = \l_mil_resume_resumetext_tl,
  cv-text      .tl_set:N   = \l_mil_resume_cvtext_tl,
  resume-mode  .bool_set:N = \l_mil_resume_mode_bool
}
\NewDocumentCommand \ResumeMode { O{true} } { % from `xparse`
  \keys_set:nn { mil / resume } { resume-mode = #1 }
}
\NewDocumentCommand \CVEntry { m } {
  \group_begin:
  \keys_set:nn { mil / resume } { #1 }
  \cventry{\l_mil_resume_start_tl--\l_mil_resume_end_tl}
          {\l_mil_resume_degree_tl}
          {\l_mil_resume_institution_tl}
          {\l_mil_resume_city_tl}
          {\l_mil_resume_grade_tl}
          {
            \bool_if:NTF \l_mil_resume_mode_bool {
              \l_mil_resume_resumetext_tl
            } {
              \l_mil_resume_cvtext_tl
            }
          }
  \group_end:
}
\ExplSyntaxOff

\moderncvstyle{oldstyle}
\name{John}{Doe}

\ResumeMode[false]

\begin{document}
\CVEntry{
  start=1993,
  end=2005,
  degree=B.\,S.,
  institution=\TeX\ StackExchange,
  city=Internet,
  grade=Grade,
  resume-text=resume text,
  cv-text=cv text,
}
\CVEntry{
  start=1993,
  end=2005,
  degree=B.\,S.,
  institution=\TeX\ StackExchange,
  city=Internet,
  grade=Grade,
  resume-text=resume text,
  cv-text=cv text,
  resume-mode=true,
}
\end{document}

The following code gives me a solution. But it is still not very nice:

\newcommand{\Cventry}[7]{\ifresume \cventry{#1}{#2}{#3}{#4}{#5}{#6} \else \cventry{#1}{#2}{#3}{#4}{#5}{#7} \fi}
