shiny 0.6.0

Breaking Changes

• shiny.run only allows positional arguments for app, host, and port, all other arguments must be specified with keywords.

New features

• shiny run now takes reload-includes and reload-excludes to allow you to define which files trigger a reload (#780).

• shiny.run now passes keyword arguments to uvicorn.run (#780).

• The @output decorator is no longer required for rendering functions; @render.xxx decorators now register themselves automatically. You can still use @output explicitly if you need to set specific output options (#747).

• Added support for integration with Quarto (#746).

• Added shiny.render.renderer_components decorator to help create new output renderers (#621).

• Added shiny.experimental.ui.popover(), update_popover(), and toggle_popover() for easy creation (and server-side updating) of Bootstrap popovers. Popovers are similar to tooltips, but are more persistent, and should primarily be used with button-like UI elements (e.g. input_action_button() or icons) (#680).

• Added CSS classes to UI input methods (#680) .

• Session objects can now accept an asynchronous (or synchronous) function for .on_flush(fn=), .on_flushed(fn=), and .on_ended(fn=) (#686).

• App() now allows static_assets to represent multiple paths. To do this, pass in a dictionary instead of a string (#763).

• The showcase_layout argument of value_box() now accepts one of three character values: "left center", "top right", "bottom". (#772)

• value_box() now supports many new themes and styles, or fully customizable themes using the new value_box_theme() function. To reflect the new capabilities, we've replaced theme_color with a new theme argument. The previous argument will continue work as expected, but with a deprecation warning. (#772)

  In addition to the Bootstrap theme names (primary ,secondary, etc.), you can now use the main Boostrap colors (purple, blue, red, etc.). You can also choose to apply the color to the background or foreground by prepending a bg- or text- prefix to the theme or color name. Finally, we've also added new gradient themes allowing you to pair any two color names as bg-gradient-{from}-{to} (e.g., bg-gradient-purple-blue).

  These named color themes aren't limited to value boxes: because they're powered by small utility classes, you can use them anywhere within your bslib-powered UI.

• Added shiny.ui.showcase_bottom(), a new shiny.ui.value_box() layout that places the showcase below the value box title and value, perfect for a full-bleed plot. (#772)

Bug fixes

• shiny run now respects the user provided reload-dir argument (#765).
• Fixed #646: Wrap bare value box value in <p /> tags. (#668)
• Fixed #676: The render.data_frame selection feature was underdocumented and buggy (sometimes returning None as a row identifier if the pandas data frame's index had gaps in it). With this release, the selection is consistently a tuple of the 0-based row numbers of the selected rows--or None if no rows are selected. (#677)
• Added tests to verify that ui input methods, ui labels, ui update (value) methods, and ui output methods work within modules (#696).
• Adjusted the @render.plot input type to be object to allow for any object (if any) to be returned (#712).
• In layout_column_wrap(), when width is a CSS unit -- e.g. width = "400px" or width = "25%" -- and fixed_width = FALSE, layout_column_wrap() will ensure that the columns are at least width wide, unless the parent container is narrower than width. (#772)

Other changes

• input_action_button() now defaults to having whitespace around it. (#758)
• layout_sidebar() now uses an <aside> element for the sidebar's container and a <header> element for the sidebar title. The classes of each element remain the same, but the semantic meaning of the elements is now better reflected in the HTML markup. (#772)
• layout_sidebar() no longer gives the sidebar main content area the role="main" attribute. (#772)
• Improved the style and appearance of the button to enter full screen in card()s and value_box()es to better adapt to Bootstrap's dark mode. (#772)

API changes

• Added shiny.ui.navset_underline() and shiny.ui.navset_card_underline() whose navigation container is similar to shiny.ui.navset_tab() and shiny.ui.navset_card_tab() respectively, but its active/focused navigation links are styled with an underline. (#772)
• shiny.ui.layout_column_wrap(width, *args) was rearranged to shiny.ui.layout_column_wrap(*args, width). Now, width will default to 200px is no value is provided. (#772)
• shiny.ui.showcase_left_center() and shiny.ui.showcase_top_right() no longer take two values for the width argument. Instead, they now take a single value (e.g., width = "30%") representing the width of the showcase are in the value box. Furthermore, they've both gained width_full_screen arguments that determine the width of the showcase area when the value box is expanded to fill the screen. (#772)
• shiny.ui.panel_main() and shiny.ui.panel_sidebar() are deprecated in favor of new API for shiny.ui.layout_sidebar(). Please use shiny.ui.sidebar() to construct a sidebar= and supply it to shiny.ui.layout_sidebar(sidebar, *args, **kwargs). (#788)
• shiny.experimental.ui.toggle_sidebar() has been renamed to shiny.ui.update_sidebar(). It's open value now only supports bool values. (#788)

API relocations

• shiny.ui's navset_pill_card() and navset_tab_card() have been renamed to navset_card_pill() and navset_card_tab() respectively (#492).
