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().
Details
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">
