cat() helpers

These helpers provide useful wrappers around cat(): most importantly they all set sep = "", and cat_line() automatically adds a newline.

Usage

cat_line(..., col = NULL, background_col = NULL, file = stdout())

cat_bullet(
  ...,
  col = NULL,
  background_col = NULL,
  bullet = "bullet",
  bullet_col = NULL,
  file = stdout()
)

cat_boxx(..., file = stdout())

cat_rule(..., file = stdout())

cat_print(x, file = "")

Arguments

...

For cat_line() and cat_bullet(), pasted together with collapse = "\n". For cat_rule() and cat_boxx() passed on to rule() and boxx() respectively.

col, background_col, bullet_col

Colors for text, background, and bullets respectively.

file

Output destination. Defaults to standard output.

bullet

Name of bullet character. Indexes into symbol

x

An object to print.

Examples

cat_line("This is ", "a ", "line of text.", col = "red")
#> This is a line of text.
cat_bullet(letters[1:5])
#> • a
#> • b
#> • c
#> • d
#> • e
cat_bullet(letters[1:5], bullet = "tick", bullet_col = "green")
