rewind 0.2.0

• rewind_disable() stops undo and redo for a session completely. It destroys each observer that rewind_enable() made. It also clears the buttons and the rail in the browser. Use rewind_pause() and rewind_resume() to stop capture for a short time. Use rewind_disable() to stop it for the rest of the session.
• rewind no longer captures fileInput(). Its value points to a temporary file on the server. Shiny deletes that file at the next upload. An old snapshot would thus point to a file that does not exist.
• Fixed: a call to rewind_pause() before the first reactive flush stopped capture for the rest of the session. A later rewind_resume() did not start it again. This occurred, for example, with a call to rewind_pause() immediately after rewind_enable(), before any input changed.
• rewind_buttons(undo_label = NULL, redo_label = NULL) now sets aria-label on the buttons. A button with an icon and no text thus has a correct accessible name.
• rewind_enable() inside a moduleServer() now has tests. The documents said “untested” before.

rewind 0.1.0

First release.

• rewind_enable() captures the session inputs into an undo and redo history. It groups the changes by time. One movement of a slider is thus one step, and not forty steps.
• rewind_track() adds the reactiveValues on the server to the history.
• rewind_step() puts several changes into one entry with a label.
• rewind_buttons() and rewind_ui() give ready-made undo and redo controls, and a scrubbable history rail.
• Keyboard shortcuts: Ctrl/Cmd + Z, Ctrl/Cmd + Shift + Z, and Ctrl + Y. They do nothing while the user types in a text field.
• A restore uses the Shiny binding of each input. It does not use a fixed update*Input() table. Inputs from other packages thus operate with no extra code.
