Functions Used for Styling Diff Components

Except for container every function specified here should be vectorized and apply formatting to each element in a character vectors. The functions must accept at least one argument and require no more than one argument. The text to be formatted will be passed as a character vector as the first argument to each function.

Usage

StyleFuns(...)

Arguments

...

named values for the slots described in the “Constructor Arguments” section below; all are optional

Value

a StyleFuns S4 object

Details

These functions are applied in post processing steps. The diff* methods do not do any of the formatting. Instead, the formatting is done only if the user requests to show the object. Internally, show first converts the object to a character vector using as.character, which applies every formatting function defined here except for container. Then show applies container before forwarding the result to the screen or pager.

Note

the slots are set to class “ANY” to allow classed functions such as those defined in the crayon package. Despite this seemingly permissive slot definition, only functions are allowed in the slots by the validation functions.
