Résumé/CV templates are abundantly available in many varieties of themes and layouts. The vitae package provides a few of the more popular templates that are suitable for most resumes. The included templates are far from comprehensive - your favourite template may not be included, or perhaps you have created your own template. This vignette explains how your LaTeX CV can be used within the package using custom templates.

Creating a vitae template

Extending vitae to support new templates involves a similar process to creating new rmarkdown document templates. An extended explanation for creating rmarkdown templates can be found in the Document Templates chapter in “R Markdown: The Definitive Guide”.

Creating a template for vitae can be broken into three parts: - Converting a CV into a Pandoc template - Adding LaTeX macros for displaying CV entries - Using the template with rmarkdown

Converting a CV into a Pandoc template

Most elements that are included in the YAML header of an rmarkdown document are passed to your template via Pandoc variables. Pandoc variables can be included in your template file by surrounding the variable with $. These can be used to fill in basic CV details such as your name, occupation, and social links.

For example, suppose your document contains this YAML header:

name: "Mitchell O'Hara-Wild"
position: "vitae maintainer"
output: vitae::awesomecv

The $name$ variable in the template would be substituted with Mitchell O'Hara-Wild and similarly, $position$ would become vitae maintainer. Many templates won’t follow this same structure exactly (some may split the name into first and last names), but most of the time there is a reasonable place for these variables. It is recommended that a consistent set of variables are used to make switching between templates easy.

The current list of variables used in the vitae templates are:

  • name
  • position
  • address
  • date
  • profilepic
  • www
  • email
  • twitter
  • github
  • linkedin
  • aboutme
  • headcolor

In the moderncv template, the position of ‘vitae maintainer’ is specified using \position{vitae maintainer}. Using Pandoc variables, this would be replaced with \position{$position$}, which allows the position to be defined in the rmarkdown document’s YAML header.

However if a position has not been provided in the YAML header, this would leave us with \position{} (which might be okay for some templates, but is undesirable for most templates). To resolve this, we can use Pandoc to conditionally include this section with $if(position)$\position{$position$}$endif$.

The main content from an rmarkdown document is also included using Pandoc variables. The results from the main section of the document is stored in $body$. So in a typical LaTeX CV template, where there is usually pre-filled details about experience and employment, this can be completely replaced with $body$. There are a few other common variables to place within the template, which are typically placed in the same location as other templates. These variables include:

  • body
  • header-includes
  • fontfamily
  • fontfamilyoptions
  • fontsize
  • lang
  • papersize
  • classoption
  • linestretch
  • include-before
  • include-after
  • highlighting-macros

Placement of these variables can be found by looking at other template files provided in the package. The conversion of the moderncv template into a Pandoc template for vitae can be found on GitHub.

Adding LaTeX macros for displaying CV entries

The interface for producing entries in a CV varies greatly between templates. To support these various formats, LaTeX macros are used to transfer the format provided by vitae into a format suitable for each template.

The moderncv template provides many different layouts, of which I have selected the two that best suit brief_entries and detailed_entries.

brief_entries

The moderncv template \cvitem command generates an appropriate layout for brief entries. It expects inputs in this format:

\cvitem{Title}{Description}

The vitae package returns brief_entries in this format:

\briefsection{
  \briefitem{what}{when}{with}
}

So in our Pandoc template’s header, we need to define macros for \briefsection and \briefitem that produce an appropriately structured \cvitem. The \briefitem provides 3 inputs, and \cventry expects 2, so we will need to combine two of the \briefitem inputs. A suitable LaTeX macro could be defined as:

% Templates for brief entries
% Arguments: what when with
\def\briefitem#1#2#3{\cvitem{#2}{#1. #3}}
\def\briefsection#1{\nopagebreak#1}

Here the \briefsection macro is essentially doing nothing (other than ensuring there will be no page break). Other CV templates use special environments for entries, where this macro is more useful (such as twentyseconds). The \briefitem macro is mapping when to the Title of the item (as this is more consistently formatted with detailed_items), and combining what and with to form the item’s Description.

detailed_entries

For detailed CV entries, the moderncv \cventry command is reasonable. It expects inputs in this format:

\cventry{Year}{Degree}{Institution}{City}{Grade}{Description}

The vitae package returns detailed_entries in this format:

\detailedsection{
  \detaileditem{what}{when}{with}{where}{\item{why1}\item{why2}...}
}

The \detaileditem provides 5 inputs, and \cventry expects 6, so we will leave the Grade section blank, as it is better suited in the “why” argument for the vitae package. The code below shows how the order of inputs to \detaileditem can be mapped onto the inputs of \cventry. To appropriately format the list of why items, we are conditionally wrapping this input in an itemize environment.

% Templates for detailed entries
% Arguments: what when with where why
\usepackage{etoolbox}
\def\detaileditem#1#2#3#4#5{
    \cventry{#2}{#1}{#3}{#4}{}{{\ifx#5\empty\else{\begin{itemize}#5\end{itemize}}\fi}}}
\def\detailedsection#1{\nopagebreak#1}

Using the template with rmarkdown

Once the Pandoc variables and LaTeX CV entry macros are set in the template, it is ready for use with the vitae package. The package provides the cv_document output format, which is suitable for use with custom templates. To use the custom template, your rmarkdown document’s YAML header would look like this:

output:
  vitae::cv_document:
    template: my_custom_template.tex

You will also need to copy all of the LaTeX class (.cls) and style (.sty) files provided with the template into the same folder as your rmarkdown document. Once that is done, your new template should be ready to use with the vitae package.

Contributing to the vitae package

If you’ve gone to the effort of successfully creating a new template with the vitae package, you may be interested in making it available for others to use. You can contribute to this package by submitting a pull request that adds your template to the package.

Adding your template to the package can be done with:

Then by navigating to the package’s inst/rmarkdown/templates/my_template folder, you can add your Pandoc template to the resources folder, and your .cls and .sty files to the skeleton folder.

Once that is done, we can create a new rmarkdown output format that uses your template. These are added to the “R/formats.R” file, and will usually follow the same structure as other templates. The template argument to cv_document is a link to your Pandoc template in the package (accessed using system.file), and it is recommended that the supporting .cls and .sty files are copied using copy_supporting_files.

#' @rdname cv_formats
#' @export
moderncv <- function(...) {
  template <- system.file("rmarkdown", "templates", "my_template",
                          "resources", "moderncv.tex", package="vitae")
  copy_supporting_files("my_template")
  cv_document(..., template = template, citation_package="biblatex", latex_engine="xelatex")
}

The automatically generated skeleton.Rmd document in the skeleton folder should be modified to be a basic example of using your template. Examples of this file can be found in other templates, and this template file can act as a useful test for your template!

All done! You should now be able to install your new version of the package with devtools::install(), and test out your new output format with:

output:
  vitae::my_template
