This function can be used directly, or via the {.val ...} inline style. {.val {expr}} calls cli_format() automatically on the value of expr, before styling and collapsing it.

cli_format(x, style = NULL, ...)

# S3 method for default
cli_format(x, style = NULL, ...)

# S3 method for character
cli_format(x, style = NULL, ...)

# S3 method for numeric
cli_format(x, style = NULL, ...)

Arguments

x

The object to format.

style

List of formatting options, see the individual methods for the style options they support.

...

Additional arguments for methods.

Details

Default style

months <- month.name[1:3]
cli_text("{.val {months}}")

nums <- 1:5 / 7
cli_text("{.val {nums}}")

Styling with themes

nums <- 1:5 / 7
divid <- cli_div(theme = list(.val = list(digits = 3)))
cli_text("{.val {nums}}")
cli_end(divid)

It is possible to define new S3 methods for cli_format and then these will be used automatically for {.val ...} expressions.

cli_format.month <- function(x, style = NULL, ...) {
  x <- encodeString(substr(x, 1, 3), quote = "\"")
  NextMethod("cli_format")
}
registerS3method("cli_format", "month", cli_format.month)
months <- structure(month.name[1:3], class = "month")
cli_text("{.val {months}}")
