ansi_strwrap: Wrap an ANSI styled string to a certain width
In RonMobile/cli: Helpers for Developing Command Line Interfaces

Description Usage Arguments Value See Also Examples

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

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

`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 charcter vector, or wrap each element of `x` independently and return a list.

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

Other ANSI string operations: ansi_align(), ansi_columns(), ansi_nchar(), ansi_strsplit(), ansi_strtrim(), ansi_substring(), ansi_substr(), ansi_toupper(), ansi_trimws()

text <- cli:::lorem_ipsum()
# Highlight some words, that start with 's'
rexp <- gregexpr("\\b([sS][a-zA-Z]+)\\b", text)
regmatches(text, rexp) <- lapply(regmatches(text, rexp), col_red)
cat(text)

wrp <- ansi_strwrap(text, width = 40)
cat(wrp, sep = "\n")
