This release focuses entirely on improving the
panelset feature, especially in Quarto web pages and
slides. Panelset is also now a Quarto extension that can be installed
with quarto add gadenbuie/xaringanExtra and can be used
with any computation engine.
panelset now works even better in Quarto documents, using the same syntax as used for panelsets in R Markdown documents (#190).
panelset now supports a fenced
div syntax where ::: {.panelset} is used to start a
panelset and each panel is defined by a new heading within the fenced
div. When used in this way, the heading level of the subsections is
ignored, the highest level subsection heading within the fenced div
determines the section level that creates a new panel (#191).
panelset CSS was revamped for better ergonomics,
in particular to improve how the border bottom separating the tabs from
the content and the bottom border of the active tab are handled.
style_panelset_tabs() gains a new
separator_color argument to replace
tabs_border_bottom (#192).
panelset now fully supports panelset chunks in
Quarto, either with #| panelset: true for chunk options or
the alternative syntax specifying the panel names for the source and
output panels (#193):
```{r}
#| panelset:
#| - source: The Code
#| - output: The Result
rnorm(10)
```Unlike in R Markdown, where you always need to place panelset chunks
in a ::: {.panelset} div, in Quarto, panelset code chunks
automatically create their own panelsets with two tabs (code and
output). Use the ::: {.panelset} syntax to add more than
one panelset code chunk to the same panelset (#196).
Nested panelsets are now supported (#194)! In xaringan slides and when using the hand-rolled panelset syntax, you can now nest panelsets within panelsets. In R Markdown or Quarto documents, panelsets chunks can be nested within panelset sections. Nesting panelset sections requires the fenced div syntax:
# Nested fenced divs
::: {.panelset #outer}
## One
Outer panel One.
::: {.panelset #inner}
### One A
Inner panel One A.
### One B
Inner panel One B.
:::
## Two
Outer panel Two.
:::panelset fully supports Quarto Revealjs Presentations. All of panelset’s features in xaringan are fully supported in Quarto slides, including automatically stepping through the panels on a slides (#195).
panelset now supports synchronized panels
(#195)! Give each panelset a group attribute with a unique
name, e.g. {.panelset group="language"}, and the selected
tab will be synchronized across all other panelsets with the same group
name. The tab selection is synchronized by tab name, so if the user
switches from the “R” tab to the “Python” tab, all panelsets with
group="language" will have their “Python” tab activated (if
they have one).
The chosen panel tab is stored in the user’s browser, which means that the user’s choice is reflected across all pages on your domain. It’s also remembered when they return to your page later (in the same browser). Technically, this feature uses the browser’s localStorage API and no user data is transmitted anywhere.
panelset is now also a Quarto extension that can be installed and used without requiring R (#195). To install the extension, run the following in your terminal.
quarto add gadenbuie/xaringanExtraThen, in your Quarto document, add the following to the YAML front matter:
filters:
- panelsetpanelset now forces the chunk options
echo = TRUE and eval = TRUE, when
panelset = TRUE is used. Without these options, panelset’s
knitr hooks can’t correctly convert the chunk source and output into two
separate panels.
When these options are disabled via a chunk option on the panelset
chunk, panelset will give an error to help you spot this issue early.
But if echo and eval are globally set to
FALSE, panelset will now automatically set them to
TRUE. This is especially helpful in Quarto revealjs
presentations where Quarto defaults to echo = FALSE
(#196).
BREAKING CHANGE: All arguments to use_banner() must
be named. use_banner() now takes ... earlier
since you may want to include style_banner() style
arguments without having to specify all the other arguments
(#169).
scribble can now be disabled on an individual
slide by adding class: no-scribble to the slide (@mattwarkentin
#166).
Embedding slides via embed_xaringan() no longer
requires that you set self_contained: false in the R
Markdown document. embed_xaringan() now automatically sets
the data-external="1" attribute on the element embedding
the xaringan slides (thanks @jhelvy, @drfurtado, #177).
editable now hides remark’s “Paused” overlay when editing slides in presenter mode (#178).
use_banner(). Banners
are text (or other HTML) that appear on every slide, for example the
title of your talk or a link to your slides online. (thanks @mattwarkentin and
@dataning,
#161)Sideways panelsets collapse to standard panelsets with tabs above the content on small devices (max-width 480px). (#122)
Keep sideways panelset tabs on screen with long-scrolling content. (#123)
The panelset=TRUE chunk option now automatically
sets results="hold" unless over-ridden by a local chunk
option.
share again no longer shows when viewing slides in the RStudio viewer pane. (#128)
use_xaringan_extras("panelset") is now equivalent to
use_panelset(). Previously the first would not install the
knitr chunk hooks.
panelset now uses the xaringan knitr source hooks, restoring line highlighting in the source panel of panelset chunks. (#138)
Hide scribble controls when printing slides (thanks @yyzeng, #136).
text_poster() has been removed.
Added color presets to scribble: press
0 through 9 while drawing to quickly toggle
through a preset color palette, customizable using the
palette argument of use_palette() (thanks
@kim-soo-hwan,
#112, #117).
New feature: animated progress bars that don’t interfere with the
slide number. Simply add use_progress_bar() to your slides!
(#109, #118)
use_freezeframe() (#102)rgb() syntax by
calling the rgb() function in R: instead of
"rgb(61, 255, 232)", you can write
rgb(61, 255, 232, maxColorValue = 255).use_scribble() you can
draw on your slides using your mouse or a tablet with stylus. Drawings
stay with each slide and scale when the slides are resized. You can
erase individual lines, undo or redo with keyboard shortcuts, or clear
the drawings on the current slide easily with the provided toolbox.
Thanks also to @LauraRK and @rpruim for suggestions and feedback. (@mattwarkentin
#87)New addin: search! Easily search through the text in your slides. (thanks @statnmap, #82)
All extensions now use version numbers that are independent of the xaringanExtra package version. This will reduce the number of copies of an extension that are added to a blogdown site’s dependencies by ensuring that unrelated package updates don’t change the extension version number.
Added panelset chunks that output code chunks source and results in separate panel tabs (#59)
Added broadcast, a new experimental extension that allows viewers to follow the presenter’s slides in their own browsers (thanks @spcanelon, #51, #58)
Changing a panelset tab now emits a window resize event in hopes that any HTMLwidgets contained in the panel will resize to fit the panel container (thanks @mfherman #64)
.tabset feature in R Markdown
documents! See the
panelset documentation for more information and examples (#41).style_share_again(): fixed
default arguments, the buttons now correctly inherit the foreground
color, and slides without an author or title are handled correctly
(thanks @mattwarkentin, #48).<iframe> in another page. Another
function embed_xaringan() is provided to embed slides in
blogdown and R Markdown HTML sites in a responsive container.Various updates do use_logo() documentation. The
class to hide the logo is .hide_logo and the logo CSS and
JavaScript are embedded directly for xaringan >= 0.16 (thanks @chainsawriot, #22,
#24, #25, #30)
Updated cookie settings when storing editable fields (#42)
Disabled spell check and auto complete in editable areas (#16)
The CSS variables for panelset have been renamed and the
arguments of style_panelset_tabs() haven been updated for
ease of use. Unfortunately, this change is not backwards compatible;
using the previous argument names will result in an informative warning
without throwing an error. The panelset also does a better job of
handling many tabs, which are now wrapped into multiple lines of tabs.
(thanks @realauggieheschmeyer, #37,
#38, #39).
In conjunction with the item above, the
style_panelset() has been renamed
style_panelset_tabs(). This more clearly describes the part
of the panelset that is styled, and it helps clarify the meaning of the
more concise function argument names.
Increased specificity of CSS rules for the panelset.
Added --panel-tab-background-color with additional
-active and -hover custom properties to style
the background color of tabs. Similarly, two CSS variables for border
color were added: --panel-tab-border-color-active and
--panel-tab-border-color-hover.
Updated Tachyons to 4.12.0 (#27)
Added clipboard extra with
use_clipboard(). Adds a “Copy Code” button to code chunks
(<pre><code>...</code></pre>) and
works in both xaringan slides and R Markdown documents (thanks @mattwarkentin #20,
#36).
Improved accessibility of panelset so that it now works with touch devices. The currently selected tab is written into the URL query to ensure that URLs resolve to currently open tab. The tab ID isn’t written into the URL hash because this is used by remarkjs to jump to the current slide. (#34, #33, #18)
Added a NEWS.md file to track changes to the
package.
text_poster() has been deprecated and will be
removed eventually.
