Usage
list_border_styles()

boxx( label, border_style = "single", padding = 1, margin = 0, float = c("left", "center", "right"), col = NULL, background_col = NULL, border_col = col, align = c("left", "center", "right"), width = console_width() )

Arguments
label

Label to show, a character vector. Each element will be in a new line. You can color it using the col_*, bg_* and style_* functions, see ansi-styles and the examples below.

border_style

String that specifies the border style. list_border_styles lists all current styles.

padding

Padding within the box. Either an integer vector of four numbers (bottom, left, top, right), or a single number x, which is interpreted as c(x, 3*x, x, 3*x).

margin

Margin around the box. Either an integer vector of four numbers (bottom, left, top, right), or a single number x, which is interpreted as c(x, 3*x, x, 3*x).

float

Whether to display the box on the "left", "center", or the "right" of the screen.

col

Color of text, and default border color. Either a style function (see ansi-styles) or a color name that is passed to make_ansi_style().

background_col

Background color of the inside of the box. Either a style function (see ansi-styles), or a color name which will be used in make_ansi_style() to create a background style (i.e. bg = TRUE is used).

border_col

Color of the border. Either a style function (see ansi-styles) or a color name that is passed to make_ansi_style().

align

Alignment of the label within the box: "left", "center", or "right".

width

Width of the screen, defaults to getOption("width").

About fonts and terminal settings

The boxes might or might not look great in your terminal, depending on the box style you use and the font the terminal uses. We found that the Menlo font looks nice in most terminals an also in Emacs.

RStudio currently has a line height greater than one for console output, which makes the boxes ugly.

boxx("Hello there!", margin = c(1, 5, 1, 5))
boxx("Hello there!", padding = 1, margin = c(1, 5, 1, 5))

## Floating
boxx("Hello there!", padding = 1, float = "center")
