Generic CLI container — cli

See containers. A cli_div container is special, because it may add new themes, that are valid within the container.

Usage

cli_div(
  id = NULL,
  class = NULL,
  theme = NULL,
  .auto_close = TRUE,
  .envir = parent.frame()
)

Arguments

id: Element id, a string. If NULL, then a new id is generated and returned.
class: Class name, sting. Can be used in themes.
theme: A custom theme for the container. See themes.
.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.

Value

The id of the new container element, invisibly.

Details

Custom themes

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

#>
#> Custom title

Auto-closing

By default a cli_div() is closed automatically when the calling frame exits.

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
