Container elements may contain other elements. Currently the following commands create container elements: cli_div(), cli_par(), the list elements: cli_ul(), cli_ol(), cli_dl(), and list items are containers as well: cli_li().

Themes

A container can add a new theme, which is removed when the container exits.

d <- cli_div(theme = list(h1 = list(color = "blue",
                                    "font-weight" = "bold")))
cli_h1("Custom title")
cli_end(d)

#>                                                                                 
#> Custom title                                                                    

Auto-closing

Container elements are closed with cli_end(). For convenience, by default they are closed automatically when the function that created them terminated (either regularly or with an error). The default behavior can be changed with the .auto_close argument.

div <- function() {
  cli_div(class = "tmp", theme = list(.tmp = list(color = "yellow")))
  cli_text("This is yellow")
}
div()
cli_text("This is not yellow any more")

#> This is yellow                                                                  
#> This is not yellow any more                                                     

Debugging

You can use the internal cli:::cli_debug_doc() function to see the currently open containers.

fun <- function() {
  cli_div(id = "mydiv")
  cli_par(class = "myclass")
  cli:::cli_debug_doc()
}
fun()

#>                                                                                 
#> <cli document>                                                                  
#> <body id="body">                                                                
#> <div id="mydiv"> +theme                                                         
#> <par id="cli-82040-226" class="myclass">
