Editable

Description

Editable gives you a way to write directly inside your slides. Make any element of your slides editable by using the .can-edit[...] class. Editable fields are reset when the slides are reloaded, but it is possible for edits to persist across sessions (in the same browser) by giving the editable element a ⁠.key-<NAME>⁠ class, where ⁠<NAME>⁠ is a unique identifier (and valid CSS class).

Usage

use_editable(id = NULL, expires = 14)

html_dependency_editable(expires = 14, id = NULL)

Arguments

id

Optional. By default, when id is NULL, each re-generation of your slides creates a new document ID. This way, values that were previously stored in the browser for an older version of your slides will not be loaded into a new version. If you are confident that the editable fields in your slides are not changing between versions, you can set the document ID so that newer versions of your slides will continue to load edited values from previous versions in the browser.

expires

Editable values that also have a .key-KEYNAME class are stored in the browser and automatically loaded when the slides are reloaded. These values are stored using cookies so that they can eventually expire and expires provides the number of days that those values should be stored before being released.

Value

An htmltools::tagList() with the editable dependencies, or an htmltools::htmlDependency.

Functions

• use_editable(): Adds editable to your xaringan slides.

• html_dependency_editable(): Returns an htmltools::htmlDependency with the tile view dependencies. Most users will want to use use_editable().

Usage

To make your xaringan presentations editable, add the following code chunk to your slides' R Markdown file.

```{r xaringan-editable, echo=FALSE}
# Setup editable fields and only store values in the browser for one day
# (by default values expire in 2 weeks).
xaringanExtra::use_editable(expires = 1)
```

Then, to make a component of your slides editable, use the .can-edit[] class.

## .can-edit[You can edit this slide title]

Editable fields that only have the .can-edit class are reset whenever the slides are re-loaded in your browser. If you want to store the edited values and have them persist across browser sessions, give each editable field a ⁠.key-<NAME>⁠ class. Be sure to make each key unique and note that the key name must be a valid CSS class, i.e. it cannot contain spaces.

## .can-edit.key-firstSlideTitle[Change this title and then reload the page]

Warning Editable fields may not work well with slide continuations. If your full slide builds up over several slides, you can only edit the currently visible slide. If the field has a key, however, all editable elements with the same key class are updated when the slides are loaded. In other words, you can edit the title on the first slide of a multi-part slide and reload the page to have the title applied to subsequent slides.
