combine_ansi_styles: Combine two or more ANSI styles

Description

Combine two or more styles or style functions into a new style function that can be called on strings to style them.

Usage

combine_ansi_styles(...)

Value

The combined style function.

Arguments

...

The styles to combine. For character strings, the make_ansi_style() function is used to create a style first. They will be applied from right to left.

Details

It does not usually make sense to combine two foreground colors (or two background colors), because only the first one applied will be used.

It does make sense to combine different kind of styles, e.g. background color, foreground color, bold font.

Other ANSI styling: ansi-styles, make_ansi_style(), num_ansi_colors()

Examples

## Use style names
alert <- combine_ansi_styles("bold", "red4")
cat(alert("Warning!"), "\n")

## Or style functions
alert <- combine_ansi_styles(style_bold, col_red, bg_cyan)
cat(alert("Warning!"), "\n")

## Combine a composite style
alert <- combine_ansi_styles(
  "bold",
  combine_ansi_styles("red", bg_cyan))
cat(alert("Warning!"), "\n")
