xaringan 0.10

NEW FEATURES

• Added the ability to specify an institute in the YAML header that is automatically added to the title slide (@paullemmens, #200).

BUG FIXES

• The Infinite Moon Reader (xaringan::inf_mr()) didn't take slide properties layout: true and exclude: true into consideration (thanks, @fmmattioni, #198).

xaringan 0.9

NEW FEATURES

• The Infinite Moon Reader (xaringan::inf_mr()) has been significantly enhanced for a much smoother user experience of authoring slides with the xaringan::moon_reader format in RStudio. The preview of the current slide will be instant (as you type in the RStudio editor), and the navigation in the source editor will be linked to the navigation of slides output. See https://yihui.name/en/2019/02/ultimate-inf-mr/ for details.

• When printing slides to PDF, only the last slide of a series of incremental slides will be printed (thanks, @sebpardo @@benjie, #192).

• Added a function decktape() to export slides to PDF via the DeckTape library (thanks, @pat-s, #177).

• Added a CSS theme uol (University of Leicester) (thanks, @ellessenne, #183).

• Added a CSS theme fc (thanks, @Yue-Jiang, #189).

• xaringan::inf_mr() can detect changes in CSS/JS and common images now. When any of these files are changed, it will rebuild the Rmd document and reload the output in the browser (thanks, @mrchypark @tcgriffith, #185).

• External links (URLs starting with http:// or https://) on slides will be opened in new browser tabs/windows.

BUG FIXES

• Fixed several long-lasting issues related to MathJax fonts and printing to PDF (#62, #73, #143, #148, #168).

xaringan 0.8

• Added a CSS theme chocolate. See here for an example slide (thanks, @liao961120, #171).

• Added a set of CSS theme kunoichi, shinobi and ninjutsu - see here for example (thanks, @emitanaka, #165).

• Added a CSS theme lucy (thanks, @LucyMcGowan, #163).

xaringan 0.7

• Added a CSS theme middlebury (Middlebury College) (thanks, @jvcasillas, #150).

• Added a CSS theme tamu (Texas A&M) (thanks, @nanhung, #115).

• Added a CSS theme rutgers (Rutgers University) (#121).

• Added a CSS theme duke-blue and corresponding hygge-duke (Duke University) (thanks, @libjohn, #133).

• In the metropolis theme, updated weights and margins of all headers, and added a new CSS class clear that disables the colored box at the top of each slide (#107).

• It is possible to customize the CSS classes of the title slide using the option titleSlideClass under the nature option of xaringan::moon_reader() now (thanks, @gadenbuie, #139, #136).

BUG FIXES

• An informative error message is now returned when trying to use an invalid or misspelled CSS theme name (thanks, @gadenbuie, #129).

• LaTeX math expressions will no longer be rendered inside the <code></code> tags (thanks, @garthtarr, #137).

• The default CSS style for tables should not be applied to the help page of the slides (thanks, @KevCaz, #138).

xaringan 0.6

NEW FEATURES

• Added CSS hygge - some template-independent CSS code for general formatting. Add as argument to xaringan::moon_reader (thanks, @ekstroem, #113).

xaringan v0.5

NEW FEATURES

• The default CSS file was split into two files default.css and default-fonts.css to make it easier to define custom font styles without copying all base CSS definitions. For example, the css argument of xaringan::moon_reader can take a vector of default and extra.css, and you define your custom font styles in extra.css.

• For the css argument, if a value does not end with .css, it is assumed to be a built-in CSS file in this package. Currently all available CSS files can be found at https://github.com/yihui/xaringan/tree/master/inst/rmarkdown/templates/xaringan/resources. See ?xaringan::moon_reader for more details. This change was to make it easier for users to contribute custom themes (https://yihui.name/en/2017/10/xaringan-themes/).

• Added a new sub-option beforeInit under the nature option, which can be used to specify JavaScript files to be executed before the instantiation of slides (i.e., before remark.create()). One application of this new feature is to define custom remark.js macros; see the slide "Macros" at https://slides.yihui.name/xaringan/ for more info (thanks, @gavinsimpson, #80).

• Line highlighting can also be turned on using a special comment #<< at the end of a line of code now (thanks, @gadenbuie, #103).

CHANGES IN xaringan VERSION 0.4

NEW FEATURES

• The PDF printed from the slides in browser looks much nicer now (no extra margins) (thanks, @cboettig and @ekstroem, #65).

BUG FIXES

• Line highlighting using {{}} does not work with multiple lines (thanks, @HeidiSeibold #53 and @aj2duncan #54).

• The option mathjax: null does not work for moon_reader(), i.e., it was not possible to exclude MathJax.

CHANGES IN xaringan VERSION 0.3

NEW FEATURES

• A new option countdown in the nature option of moon_reader() can be set so that a countdown timer is added to each page of slides. See ?xaringan::moon_reader and https://slides.yihui.name/xaringan/ for more information (thanks, @slopp, #43).

CHANGES IN xaringan VERSION 0.2

NEW FEATURES

• A class title-slide was added to the automatically generated title slide (moon_reader(seal = TRUE)) so that you can customize the this slide using CSS (thanks, @ekstroem, #7).
• Added an argument cast_from to infinite_moon_reader() to specify the root directory of the server. Previously the root directory is the directory of the Rmd input file, which makes it impossible for the Rmd document to use resources in upper-level directories (e.g. ![](../gif/cute-kittens.gif)). Now you can set the working directory to the upper-level directory and call inf_mr('relative/path/to/input.Rmd'), so that input.Rmd can use any files under the current working directory ./ (thanks, @pat-s, #29).
• Added a Wiki on Github thanks to @pat-s for those who are new to CSS: https://github.com/yihui/xaringan/wiki

BUG FIXES

• A local copy of MathJax should work with moon_reader() (thanks, @bnicenboim, #13).
• Skip fenced code blocks when detecting LaTeX math expressions, e.g. $api$ in R code session$api$plot <- ... should not be treated as a math expression (thanks, @jcheng5).
• Unicode characters can be rendered correctly on Windows now (thanks, @Lchiffon, #20).

Initial CRAN release

This is the initial CRAN release. It contains an R Markdown output format xaringan::moon_reader(), and a few helper functions, e.g. xaringan::infinite_moon_reader() and summon_remark().
