default_style: Default 'prettycode' syntax highlighting style

In prettycode: Pretty Print R Code in the Terminal

Description

A style function must return a named list of functions. Possible entries:

• reserved: reserved words

• number: numeric literals

• null: the NULL constant

• operator: operators, including assignment

• call: function calls

• string: character literals

• comment: comments

• bracket: brackets: (){}[]

Usage

default_style()

Details

Each entry in a list must be a function that takes a character scalar, and returns a character scalar with the exception of bracket which should be a list of functions defining a color sequence. The default style adds ANSI formatting to the code.

Note that you can also change the code if you like, e.g. to include a unicode arrow character instead of the two-character assignment operator.

Examples

highlight(deparse(get), style = default_style())
