manage_stacks: Plugin module for managing board stacks

In blockr.core: Graphical Web-Framework for Data Manipulation and Visualization

Plugin module for managing board stacks

Description

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

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).

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.
