Ordered CLI list

Description

An ordered list is a container, see containers.

Usage

cli_ol(
  items = NULL,
  id = NULL,
  class = NULL,
  .close = TRUE,
  .auto_close = TRUE,
  .envir = parent.frame()
)

Arguments

`items`	If not `NULL`, then a character vector. Each element of the vector will be one list item, and the list container will be closed by default (see the `.close` argument).
`id`	Id of the list container. Can be used for closing it with `cli_end()` or in themes. If `NULL`, then an id is generated and returned invisibly.
`class`	Class of the list container. Can be used in themes.
`.close`	Whether to close the list container if the `items` were specified. If `FALSE` then new items can be added to the list.
`.auto_close`	Whether to close the container, when the calling function finishes (or `.envir` is removed, if specified).
`.envir`	Environment to evaluate the glue expressions in. It is also used to auto-close the container if `.auto_close` is `TRUE`.

Details

Adding all items at once

fun <- function() {
  cli_ol(c("one", "two", "three"))
}
fun()

#> 1. one                                                                          
#> 2. two                                                                          
#> 3. three

Adding items one by one

## Adding items one by one
fun <- function() {
  cli_ol()
  cli_li("{.emph one}")
  cli_li("{.emph two}")
  cli_li("{.emph three}")
  cli_end()
}
fun()

#> 1. one                                                                          
#> 2. two                                                                          
#> 3. three

Nested lists

fun <- function() {
  cli_div(theme = list(ol = list("margin-left" = 2)))
  cli_ul()
  cli_li("one")
  cli_ol(c("foo", "bar", "foobar"))
  cli_li("two")
  cli_end()
  cli_end()
}
fun()

#> • one                                                                           
#>     1. foo                                                                      
#>     2. bar                                                                      
#>     3. foobar                                                                   
#> • two

The id of the new container element, invisibly.
