Construct a custom pillar object — new

new_pillar() is the low-level constructor for pillar objects. It supports arbitrary components. See pillar() for the high-level constructor with default components.

new_pillar(components, ..., width = NULL, class = NULL, extra = deprecated())

Arguments

components: A named list of components constructed with pillar_component().
...: These dots are for future extensions and must be empty.
width: Default width, optional.
class: Name of subclass.
extra: Deprecated.

Details

Arbitrary components are supported. If your tibble subclass needs more or different components in its pillars, override or extend ctl_new_pillar() and perhaps ctl_new_pillar_list().

Examples

lines <- function(char = "-") {
  stopifnot(nchar(char) == 1)
  structure(char, class = "lines")
}

format.lines <- function(x, width, ...) {
  paste(rep(x, width), collapse = "")
}

new_pillar(list(
  title = pillar_component(new_ornament(c("abc", "de"), align = "right")),
  lines = new_pillar_component(list(lines("=")), width = 1)
))
#> <pillar>
#> abc
#>  de
