Plugin module for managing board stacks

Source: R/plugin-stacks.R
manage_stacks.Rd

Logic and user experience for adding new, removing and modifying existing stacks to/from the board can be customized or enhanced by providing an alternate version of this plugin. The default implementation provides a table-based UI, presented in a modal.

Usage

manage_stacks(server = manage_stacks_server, ui = manage_stacks_ui)

manage_stacks_server(id, board, update, ...)

manage_stacks_ui(id, board)

Arguments

server, ui

Server/UI for the plugin module

id

Namespace ID

board

The initial board object

update

Reactive value object to initiate board updates

...

Extra arguments passed from parent scope

Value

A plugin container inheriting from manage_stacks is returned by manage_stacks(), while the UI component (e.g. manage_stacks_ui()) is expected to return shiny UI (i.e. shiny::tagList()) and the server component (i.e. manage_stacks_server()) is expected to return NULL.

Details

Updates are mediated via the shiny::reactiveVal() object passed as update, where stack updates are communicated as list entry stacks with components add, rm or mod, where

  • add is either NULL or a stacks object (stack IDs may not already exists),

  • rm is either NULL or a character vector of (existing) stack IDs,

  • mod is either NULL or a stacks object (where stack IDs must already exist).
