Exclude or include inputs by pattern

snap_exclude() adds regular expressions; inputs whose fully namespaced id matches any of them are left out of snapshots and ignored on restore. snap_include() adds patterns that an id must match to be captured at all. Both accumulate over calls within a session and complement the exclude/include arguments of snap_enable() and snap_take().

Usage

snap_exclude(patterns, session = shiny::getDefaultReactiveDomain())

snap_include(patterns, session = shiny::getDefaultReactiveDomain())

Arguments

patterns

A character vector of regular expressions, matched against fully namespaced input ids (for example "^mod-btn_").

session

The Shiny session. Defaults to the current session.

Value

The complete vector of patterns registered so far, invisibly.

Details

Ids excluded with shiny's setBookmarkExclude() are always honoured too, and action buttons, password inputs, and file inputs are never captured as input values.

Examples

if (interactive()) {
  library(shiny)

  server <- function(input, output, session) {
    snap_exclude(c("^btn_", "^nav_"))
    snap_include(c("^model_", "^prefs_"))
  }
}
