 # shiny (development version)

-## New features
-
-* `textInput()`, `textAreaInput()`, `numericInput()` and `passwordInput()` all gain an `updateOn` option. `updateOn = "change"` is the default and previous behavior, where the input value updates immediately whenever the value changes. With `updateOn = "blur"`, the input value will update only when the text input loses focus or when the user presses Enter (or Cmd/Ctrl + Enter for `textAreaInput()`). (#4183)
-
-* `textAreaInput()` gains a `autoresize` option, which automatically resizes the text area to fit its content.
-
-* The `callback` argument of Shiny.js' `InputBinding.subscribe()` method gains support for a value of `"event"`. This makes it possible for an input binding to use event priority when updating the value (i.e., send immediately and always resend, even if the value hasn't changed).
-
-## Changes
-
-* Shiny no longer suspends input changes when _any_ `<input type="submit">` or `<button type="submit">` is on the page. Instead, it now only suspends when a `submitButton()` is present. If you have reason for creating a submit button from custom HTML, add a CSS class of `shiny-submit-button` to the button.
-
-## Improvements
-
-* When auto-reload is enabled, Shiny now reloads the entire app when support files, like Shiny modules, additional script files, or web assets, change. To enable auto-reload, call `devmode(TRUE)` to enable Shiny's developer mode, or set `options(shiny.autoreload = TRUE)` to specifically enable auto-reload. You can choose which files are watched for changes with the `shiny.autoreload.pattern` option. (#4184)
-
-* When busy indicators are enabled (i.e., `useBusyIndicators()`), Shiny now:
-    * Shows a spinner on recalculating htmlwidgets that have previously rendered an error (including `req()` and `validate()`). (#4172)
-    * Shows a spinner on `tableOutput()`. (#4172)
-    * Places a minimum height on recalculating outputs so that the spinner is always visible. (#4172)
-
-* Shiny now uses `{cli}` instead of `{crayon}` for rich log messages. (@olivroy #4170)
-
-* Shiny's Typescript assets are now compiled to ES2021 instead of ES5. (#4066)
-
-## Bug fixes
-
-* Fixed a bug with modals where calling `removeModal()` too quickly after `showModal()` would fail to remove the modal if the remove modal message was received while the modal was in the process of being revealed. (#4173)
-
-* The Shiny Client Console (enabled with `shiny::devmode()`) no longer displays duplicate warning or error message. (#4177)
-
-* Updated the JavaScript used when inserting a tab to avoid rendering dynamic UI elements twice when adding the new tab via `insertTab()` or `bslib::nav_insert()`. (#4179)
-
-# shiny 1.10.0
-
 ## New features and improvements

-* When busy indicators are enabled (i.e., `useBusyIndicators()` is in the UI), Shiny now:
-    * Shows the pulse indicator when dynamic UI elements are recalculating and no other spinners are visible in the app. (#4137)
-    * Makes the pulse indicator slightly smaller by default and improves its appearance to better blend with any background. (#4122)
-
-* Improve collection of deep stack traces (stack traces that are tracked across steps in an async promise chain) with `{coro}` async generators such as `{elmer}` chat streams. Previously, Shiny treated each iteration of an async generator as a distinct deep stack, leading to pathologically long stack traces; now, Shiny only keeps/prints unique deep stack trace, discarding duplicates. (#4156)
-
-* Added an example to the `ExtendedTask` documentation. (@daattali #4087)
-
-## Bug fixes
-
-* Fixed a bug in `conditionalPanel()` that would cause the panel to repeatedly show/hide itself when the provided condition was not boolean. (@kamilzyla, #4127)
-
-* Fixed a bug with `sliderInput()` when used as a range slider that made it impossible to change the slider value when both handles were at the maximum value. (#4131)
-
-* `dateInput()` and `dateRangeInput()` no longer send immediate updates to the server when the user is typing a date input. Instead, it waits until the user presses Enter or clicks out of the field to send the update, avoiding spurious and incorrect date values. Note that an update is still sent immediately when the field is cleared. (#3664)
-
-* Fixed a bug in `onBookmark()` hook that caused elements to not be excluded from URL bookmarking. (#3762)
-
-* Fixed a bug with stack trace capturing that caused reactives with very long async promise chains (hundreds/thousands of steps) to become extremely slow. Chains this long are unlikely to be written by hand, but `{coro}` async generators and `{elmer}` async streaming were easily creating problematically long chains. (#4155)
-
-* Duplicate input and output IDs -- e.g. using `"debug"` for two inputs or two outputs -- or shared IDs -- e.g. using `"debug"` as the `inputId` for an input and an output -- now result in a console warning message, but not an error. When `devmode()` is enabled, an informative message is shown in the Shiny Client Console. We recommend all Shiny devs enable `devmode()` when developing Shiny apps locally. (#4101)
-
-* Updating the choices of a `selectizeInput()` via `updateSelectizeInput()` with `server = TRUE` no longer retains the selected choice as a deselected option if the current value is not part of the new choices. (@dvg-p4 #4142)
-
-* Fixed a bug where stack traces from `observeEvent()` were being stripped of stack frames too aggressively. (#4163)
-
-# shiny 1.9.1
-
-## Bug fixes
-
-* Fixed a bug introduced in v1.9.0 where the boundaries of hover/click/brush regions on plots were being incorrectly scaled when browser zoom was used. (#4111)
-
-# shiny 1.9.0
-
-## New busy indication feature
-
-Add the new `useBusyIndicators()` function to any UI definition to:
-  1. Add a spinner overlay on calculating/recalculating outputs.
-  2. Show a page-level pulsing banner when Shiny is busy calculating something (e.g., a download, side-effect, etc), but no calculating/recalculating outputs are visible.
-
-In a future version of Shiny, busy indication will be enabled by default, so we encourage you to try it out now, provide feedback, and report any issues.
-
-In addition, various properties of the spinners and pulse can be customized with `busyIndicatorOptions()`. For more details, see `?busyIndicatorOptions`. (#4040, #4104)
-
-## New features and improvements
-
-* The client-side TypeScript code for Shiny has been refactored so that the `Shiny` object is now an instance of class `ShinyClass`. (#4063)
-
-* In TypeScript, the `Shiny` object has a new property `initializedPromise`, which is a Promise-like object that can be `await`ed or chained with `.then()`. This Promise-like object corresponds to the `shiny:sessioninitialized` JavaScript event, but is easier to use because it can be used both before and after the events have occurred. (#4063)
-
+* Added new functions, `useBusyIndicators()` and `busyIndicatorOptions()`, for enabling and customizing busy indication. Busy indicators provide a visual cue to users when the server is busy calculating outputs or otherwise serving requests to the client. When enabled, a spinner is shown on each calculating/recalculating output, and a pulsing banner is shown at the top of the page when the app is otherwise busy. (#4040)
 * Output bindings now include the `.recalculating` CSS class when they are first bound, up until the first render. This makes it possible/easier to show progress indication when the output is calculating for the first time. (#4039)

-* A new `shiny.client_devmode` option controls client-side devmode features, in particular the client-side error console introduced in shiny 1.8.1, independently of the R-side features of `shiny::devmode()`. This usage is primarily intended for automatic use in Shinylive. (#4073)
-
-* Added function `reactlogAddMark()` to programmatically add _mark_ed locations in the reactlog log without the requirement of keyboard bindings during an idle reactive moment. (#4103)
-
 ## Bug fixes

 * `downloadButton()` and `downloadLink()` are now disabled up until they are fully initialized. This prevents the user from clicking the button/link before the download is ready. (#4041)
-
 * Output bindings that are removed, invalidated, then inserted again (while invalidated) now correctly include the `.recalculating` CSS class. (#4039)
-
 * Fixed a recent issue with `uiOutput()` and `conditionalPanel()` not properly lower opacity when recalculation (in a Bootstrap 5 context). (#4027)

-* Image outputs that were scaled by CSS had certain regions that were unresponsive to hover/click/brush handlers. (#3234)
-
 # shiny 1.8.1.1

 * In v1.8.1, shiny.js starting throwing an error when input/output bindings have duplicate IDs. This error is now only thrown when `shiny::devmode(TRUE)` is enabled, so the issue is still made discoverable through the JS error console, but avoids unnecessarily breaking apps that happen to work with duplicate IDs.

 * Added a JavaScript error dialog, reporting errors that previously were only discoverable by opening the browser's devtools open. Since this dialog is mainly useful for debugging and development, it must be enabled with `shiny::devmode()`. (#3931)

-* `runExample()` now uses the `{bslib}` package to generate a better looking result. It also gains a `package` argument so that other packages can leverage this same function to run Shiny app examples. For more, see `?runExample`. (#3963, #4005)

 #' Customize busy indicator options

-#' @description
-#' Shiny automatically includes busy indicators, which more specifically means:
-#'   1. Calculating/recalculating outputs have a spinner overlay.
-#'   2. Outputs fade out/in when recalculating.
-#'   3. When no outputs are calculating/recalculating, but Shiny is busy

-#'     pulsing banner is shown.
-#'
-#' This function allows you to customize the appearance of these busy indicators
-#' by including the result of this function inside the app's UI. Note that,
-#' unless `spinner_selector` (or `fade_selector`) is specified, the spinner/fade
-#' customization applies to the parent element. If the customization should
-#' instead apply to the entire page, set `spinner_selector = 'html'` and
-#' `fade_selector = 'html'`.
+#' When busy indicators are enabled (see [useBusyIndicators()]), a spinner is

-\item Calculating/recalculating outputs have a spinner overlay.
-\item Outputs fade out/in when recalculating.
-\item When no outputs are calculating/recalculating, but Shiny is busy
-doing something else (e.g., a download, side-effect, etc), a page-level
-pulsing banner is shown.
-}
-
-This function allows you to customize the appearance of these busy indicators
-by including the result of this function inside the app's UI. Note that,
-unless \code{spinner_selector} (or \code{fade_selector}) is specified, the spinner/fade
-customization applies to the parent element. If the customization should
-instead apply to the entire page, set \code{spinner_selector = 'html'} and
-\code{fade_selector = 'html'}.
+When busy indicators are enabled (see \code{\link[=useBusyIndicators]{useBusyIndicators()}}), a spinner is
+shown on each calculating/recalculating output, and a pulsing banner is shown
+at the top of the page when the app is otherwise busy. This function allows
+you to customize the appearance of those busy indicators. To apply the
+customization, include the result of this function inside the app's UI.

+# Development Rules
+* Put Imports at top
+* Put Exports at bottom
+* File / Folder structure
+  * Lean towards using more many files / folder vs larger files
+  * Nest folders inside larger _ideas_
+  * Each folder should generally have an `**/index.ts` to export most everything for the folder
+    * Exception: `./src/window` folder. Must call methods directly.
+* Any `window.***` calls are done in `./src/window` folder only.
+  * Add exported values / function if necessary.
+  * This helps keep each file self contained. Trying not to have random inputs from anywhere
+* jQuery
+  * Always import `./src/jquery` instead of `"jquery"`
+    * Exeption: Test files. There, you can import `"jquery"` directly as the browser is not available to already have jQuery loaded.
+  * Prevents from installing local jquery in addition to global jquery
+    * WAY to many packages exist on the assumption that jquery is available at run time. Therefore, it can not be removed globally. :-(
+* Anything that needs to be initialized on start **must** exist in the `./src/initialize` folder.
+  * No file should produce any side effects.
+  * To capture initializations, export a `setFoo(foo_)` method that updates a locally defined `foo` variable.
+
+
+# TODO
+
+* √ Move everything into a single ts file. This will allow for the functions to find themselves
+  * √ Except the utils.js already converted
+* √ es6 shiny.js
+  * √ Pass in version using esbuild
+  * √ Move all shiny files in order to main.ts
+  * √ validate polyfills are working by finding them in the code
+* √ Produce minified shiny js
+* √ Disable $ from being found without an import
+  * √ Using a patch with yarn v2
+* √ Document `./package.json` scripts
+* √ Verify that `babel` is configurable
+  * √ Use targeting browsers
+  * √ Verify it works on phantomjs / shinytest
+* √ Set up initial jest tests
+* √ Use a global shim to avoid importing jquery directly, but make testing easy to test
+* Update the /tools/update*.R scripts to produce a version and install node dependencies
+  * √ jquery
+  * √ ion range slider
+  * √ selectize
+  * √ strftime
+  * √ bootstrap date picker
+  * font awesome?
+  * bootstrap accessibility plugin?
+
+# Round #2
+* Convert registered bindings
+  * √ Input bindings
+  * √ Output bindings
+* Add default value to `subscribe(callback)` callback function of `false`. B/c if the value was not provided, it was not truthy, therefore equivalent to `false`.
+  * √ radio
+  * √ checkboxgroup
+  * √ daterange
+  * √ actionbutton
+  * √ bootstraptabinput
+* √ snake_case to camelCase conversions.
+* √ globally import strftime from `window.strftime`
+* Remove `evt` from jQuery.on callbacks where `evt` was not used.
+  * √ checkbox.subscribe
+  * √ checkboxgroup.subscribe
+  * √ radio.subscribe
+  * √ slider.subscribe

+  * √ bootstraptabinput.subscribe
+* Convert usage of `+x` to `Number(x)`
+  * https://stackoverflow.com/a/15872631/591574
+  * √ slider.getValue()
+  * √ number.getValue()
+* √ Adjust tabinput.ts `setValue()` to return either `false | void`, not `false | true`.
+  * What matters is that `false` is returned, or nothing is returned. Replaced `return true;` with `return;`
+* Questions
+  * Why does `receiveMessage(data)` sometimes have a `label`?
+  * Should we have a update datatables script?
+
+
+# Later TODO
+
+* Use --strictNullChecks in tsconfig.json
+
+* Make `_*()` methods `private *()`
+* √ Each _file_ will be pulled out as possible into smaller files in separate PRs
+* √ Convert `FileProcessor` to a true class definition
+* Break up `./utils` into many files
+  * √ Remove any `: any` types
+* √ Make `@typescript-eslint/explicit-module-boundary-types` an error
+* √ Fix all `// eslint-disable-next-line no-prototype-builtins` lines
+* TypeScript other shiny files (ex: showcasemode)
+* √ Completely remove `parcel` from `./package.json` and only use `esbuild`
+* √ Delete 'shiny-es5' files
+* Delete 'old' folder
+* _Uglify_ js files (like in previous Gruntfile.js)
+  * datepicker
+  * ionrangeslider
+  * selectize

This generates a warning during `R CMD check`. The `captureStackTraces` function is removed from `hybrid_chain`. Instead stack traces are captured and annotated by a `captureStackTraces` invoked by `runApp` higher up the call stack.	2024-05-30 21:33:00 -04:00

George Stagg	78f3f1180e	Reduce amount of call stack used in hybrid_chain Replaces `tryCatch` in `hybrid_chain` with `withCallingHandlers`. This improves Shiny on webR on Safari < 16.4 by reducing the amount of call stack used during deep nested calls to `hybrid_chain`. A `delayedAssign` is used so that if the error condition handler is invoked, the condition is handled or re-thrown in the context of `hybrid_chain`, rather than the context of the inner function deeper in the stack. The `finally` argument is reimplemented with an `on.exit()`.	2024-05-30 21:32:56 -04:00
