# htmlwidgets 1.6.4

This release reverts the change made in v1.6.3 (to no longer recurse
into list-like objects when searching for JavaScript strings wrapped
in `JS()`). Although that change helped prevent infinite recursion in
some cases, it ultimately broke too many existing widgets that relied
on the previous behavior. If you encounter infinite recursion errors
("C stack usage is too close to the limit"), the best strategy is to
coerce the offending items to a character string. (#478)

# htmlwidgets 1.6.3

### Potentially breaking changes

* Closed #466: htmlwidgets no longer recurses into list-like objects
  when searching for JavaScript strings wrapped in `JS()`, unless the
  object has the class `"list"` or `"data.frame"`. This stops
  htmlwidgets from (possibly infinitely) recursively searching objects
  that are not actually recursive. Widget authors who relied on the
  previous behavior should ensure that their widget's `JS()` calls are
  wrapped in objects that have the class `"list"` or
  `"data.frame"`. (#467)

htmlwidgets 1.6.2
------------------------------------------------------

* Closed #452: `as.tag.htmlwidget()` now includes `...` in it's
  function signature (for compatibility with the `htmltools::as.tags`
  generic).

Log message:
(www/R-htmlwidgets) Updated 1.5.4 to 1.6.1

htmlwidgets 1.6.1
------------------------------------------------------

### Bug fixes

* Closed #456: Fixed an issue where widgets were no longer being
  resized properly when rendered in a standalone fashion. (#458)

htmlwidgets 1.6.0
-------------------------------------------------------

### Potentially breaking changes

* `shinyWidgetOutput()` and `sizingPolicy()` both gain a new `fill`
  parameter. When `TRUE` (the default), the widget's container element
  is allowed to grow/shrink to fit it's parent container so long as
  that parent is opinionated about its height and has been marked with
  `htmltools::bindFillRole(x, container = TRUE)`. (#442)

  * The primary motivation for this is to allow widgets to grow/shrink
    by default [inside
    \ 
`bslib::card_body_fill()`](https://rstudio.github.io/bslib/articles/cards.html#responsive-sizing)

  * Widgets that aren't designed to fill their container in this way
    should consider setting `sizingPolicy(fill =
    FALSE)`/`shinyWidgetOutput(fill = FALSE)` and/or allowing users to
    customize these settings (i.e., add a `fill` argument to the
    `customWidgetOutput()` function signature).

* `shinyWidgetOutput()`'s `reportSize` argument now defaults to
  `TRUE`. This way, calling `shiny::getCurrentOutputInfo()` inside a
  `shinyRenderWidget()` context will report the current height and
  width of the widget.

### Improvements

* Closed #433 and #440: `saveWidget(selfcontained=TRUE)` now uses the
  `{rmarkdown}` package to discover and call pandoc, which fixes a
  couple existing issues and helps "future proof" this code path from
  future changes to pandoc.

* Closed #257 and #358: `saveWidget(selfcontained=TRUE)` now correctly
  prevents HTML from being interpreted as markdown. (#401)

-------------------------------------------------------

* Closed #320: `getDependency()` no longer includes an absolute src path in its \

Log message:
(www/R-htmlwidgets) Updated 1.3 to 1.5.3

htmlwidgets 1.5.3
-------------------------------------------------------

### New features

* Added a `reportTheme` argument to `shinyWidgetOutput()`. If `TRUE`,
  CSS styles of the widget's output container are made available to
  `shiny::getCurrentOutputInfo()`, making it possible to provide
  'smart' styling defaults in a `renderWidget()` context. (#361)

* `shinyRenderWidget()` now has a `cacheHint` parameter, for use with
  Shiny's new `bindCache()` function. (#391)

* Support a new `PACKAGE::widget_html.WIDGETNAME` convention for
  defining custom widget HTML. This replaces the earlier
  `PACKAGE::WIDGETNAME_html` convention, which continues to work but
  may be deprecated at some point in the future. The goal for the new
  convention is to prevent accidentally matching functions that were
  never intended for this purpose. (Thanks, @thebioengineer!) (#376)

* Export the `JSEvals` function, allowing other packages to support
  `JS()` in non-widget contexts.

### Bug fixes

* `saveWidget()` now `file` argument now properly handles relative
  paths. (#299)

* Fixed an issue with passing named function declarations to `JS()`
  and `onRender()` (introduced by v1.4). (#356)

htmlwidgets 1.5.2
-------------------------------------------------------

* Emergency patch release to fix an issue with rendering htmlwidgets
  in flexdashboard. More generally, this change implies that any
  htmlwidget is printed via a knitr code chunk with multiple values
  for fig.width/fig.height, only the first value is used for the
  widget's sizing policy. (#387)

htmlwidgets 1.5.1
-------------------------------------------------------

* Fixed an issue with dynamically rendered widgets (i.e., using
  `shiny::uiOutput()` to render a widget) with any version of shiny
  prior to 1.4. This issue was introduced by htmlwidgets 1.5. (#351)

htmlwidgets 1.5
-----------------------------------------------------------------------

* Fixed an incompatibility with Shiny v1.4.0: due to Shiny upgrading
  from jQuery 1.x to 3.x, the timing of some initialization routines
  has changed. This caused some widget `renderValue` calls to occur at
  an earlier point in Shiny's initialization process than with earlier
  versions of Shiny. (#345)

htmlwidgets 1.4 (unreleased)
-----------------------------------------------------------------------

* JavaScript statements can now be passed along to `onRender()` and
  `JS()` (#329).

Log message:
Update all R packages to canonical form.

The canonical form [1] of an R package Makefile includes the
following:

- The first stanza includes R_PKGNAME, R_PKGVER, PKGREVISION (as
  needed), and CATEGORIES.

- HOMEPAGE is not present but defined in math/R/Makefile.extension to
  refer to the CRAN web page describing the package.  Other relevant
  web pages are often linked from there via the URL field.

This updates all current R packages to this form, which will make
regular updates _much_ easier, especially using pkgtools/R2pkg.
