This function is similar to base::strwrap(), but works on ANSI styled strings, and leaves the styling intact.

Usage

ansi_strwrap(
  x,
  width = console_width(),
  indent = 0,
  exdent = 0,
  simplify = TRUE
)

Arguments

x

ANSI string.

width

Width to wrap to.

indent

Indentation of the first line of each paragraph.

exdent

Indentation of the subsequent lines of each paragraph.

simplify

Whether to return all wrapped strings in a single character vector, or wrap each element of x independently and return a list.

Value

If simplify is FALSE, then a list of character vectors, each an ANSI string. Otherwise a single ANSI string vector.
