color_brackets: Colored brackets

In prettycode: Pretty Print R Code in the Terminal

Description

Add color to brackets. Brackets will be coloured consecutively with the colors provided in color_seq by scope.

Usage

color_brackets(x, color_seq = list(yellow, blue, cyan))

Arguments

x	a character vector of brackets consisting of a valid sequence of any of the following: '[[', '[', ']', '(', ')', '{', '}'
color_seq	a list of functions that take and return a character scalar

Details

Meant for coloring brackets encountered within highlight. Note that occurrences of 'orphan' brackets are not taken into account mainly due to the fact that cases such as

foo <- function(x){ `[`(x, 1) }

will either be converted to

foo <- function(x){ x[1]}

before the brackets are coloured if passed in as highlight(deparse(foo)) or will be identified as a 'SYMBOL_FUNCTION_CALL' token instead of 'LBB' if passed in as

highlight("foo <- function(x){ `[`(x, 1) }")

Similarly, invalid code that would lead to orphaned brackets is not taken into account as this would be caught before hand in highlight.
