revealjs (development version)

REVEAL JS LIBRARY UPDATE

This version of the package comes with reveal.js v4 which is a major update from previous reveal.js v3. Built-in plugins (zoom, search and notes) have been updated, as well as third party plugin included in this package (menu and chalkboard). A lot of bugfixes and improvements have been made in the upstream library and now the R package can benefit from it. However, this cause also some breaking changes for revealjs R package that we described below.

You can see reveal.js releases notes since 3.3 (which was the previous version used in this package) inside their repo: https://github.com/hakimel/reveal.js/tags

Known breaking / visible changes

  • Order of menu icons have been changed.

  • When search: true is set to activate Search plugin, CTRL+SHIFT+F needs to be press to show the search box. Previously, search box was shown by default on slides.

  • For chalkboard plugin, pen and color configurations are no more supported. If you were using those, it will have no effect. chalkboard now includes several colors by default and this can't be customized easily. Available colors can be easily selected when Note or Chalboard activated. See documentation of the plugin for more information.

OTHER CHANGES

  • Add toc and toc_depth argument in revealjs_presentation() as with rmarkdown::html_document(). Set toc = TRUE to create a slide after the title slide containing a Table Of Content. toc_depth = 3 by default (as Pandoc) - its value must be adjusted with slide_level is you do not get the desired result, depending if you are using 2D slides or not.

  • smart argument has been removed from revealjs_presentation() has no more used by rmarkdown. smart = TRUE is still the default. If you need to deactivate, use md_extensions = "-smart".

  • Add title-slide id on the auto generated title slide to ease the styling using CSS.

  • Support more Pandoc's variable in revealjs_presentation() as documented in Pandoc for HTML slides:

  • background-image to customize the option parallaxBackgroundImage. This duplicates the variable parallaxBackgroundImage which still get precedence.
  • institute to provide another line in title slide between author and date
  • toc-title to provide a Title above the toc when toc = TRUE

  • Fix template to add the necessary CSS to format columns layout and other Pandoc's features (thanks, @atusy, #82).

  • Fix an issue with some configurations keys for chalkboard plugin - multiple value are now correctly passed to Pandoc's template (thanks, @grayknight2, @atusy, #62, #88).

  • Fix issues with quoting of options when passed as variables to Pandoc. This was caused by a change in Pandoc 2.14.0.3 which now sets some default value for reveal.js options (thanks, @iain-palmer, #72).

  • Update included Document template with several examples of available feature.

  • Add md_extensions argument in revealjs_presentation() (thanks, @atusy, #75).
