textMarkupInput: Create a Text Markup Input Control

In stefanieschneider/shinyhighlightr: Create Text Markup Input Controls with 'Shiny'

Description

Create a text markup input control to highlight patterns in text values. Two input fields are created: one to specify the expression to be marked; another where this expression is marked in unstructured text values, e.g., test cases for a regular expression.

Usage

textMarkupInput(inputId, labels, values = list("", ""), width = NULL,
  height = NULL, placeholders = NULL)

Arguments

inputId	The input slot that will be used to access the values.
labels	Display labels for the control, or NULL for no labels.
values	A list of vectors of initial values.
width	The width of the input, e.g., '100%'; see validateCssUnit.
height	The height of the input, e.g., '400px'; see validateCssUnit.
placeholders	A vector of character strings giving the user a hint as to what can be entered into the control. Internet Explorer 8 and 9 do not support this option.

Value

A text markup input control that can be added to a UI definition.
