print_color {insight}

Coloured console output

Description

Convenient function that allows coloured output in the console. Mainly implemented to reduce package dependencies.

Usage

print_color(text, color)

print_colour(text, colour)

color_text(text, color)

colour_text(text, colour)

color_theme()

Arguments

text

The text to print.

color, colour

Character vector, indicating the colour for printing. May be one of "white", "black", "red", "yellow", "green", "blue", "violet", "cyan" or "grey". Bright variants of colors are available by adding the prefix "b" (or "br_" or "bright_"), e.g. "bred" (or "br_red" resp. "bright_red"). Background colors can be set by adding the prefix "bg_" (e.g. "bg_red"). Formatting is also possible with "bold" or "italic".

Details

This function prints text directly to the console using cat(), so no string is returned. color_text(), however, returns only the formatted string, without using cat(). color_theme() either returns "dark" when RStudio is used with dark color scheme, "light" when it's used with light theme, and NULL if the theme could not be detected.

Value

Nothing.

Examples

print_color("I'm blue dabedi dabedei", "blue")
