R: Update the status bar (superseded)

cli_status {cli}

R Documentation

Update the status bar (superseded)

Description

The ⁠cli_status_*()⁠ functions are superseded by the cli_progress_message() and cli_progress_step() functions, because they have a better default behavior.

The status bar is the last line of the terminal. cli apps can use this to show status information, progress bars, etc. The status bar is kept intact by all semantic cli output.

Usage

cli_status(
  msg,
  msg_done = paste(msg, "... done"),
  msg_failed = paste(msg, "... failed"),
  .keep = FALSE,
  .auto_close = TRUE,
  .envir = parent.frame(),
  .auto_result = c("clear", "done", "failed", "auto")
)

Arguments

`msg`	The text to show, a character vector. It will be collapsed into a single string, and the first line is kept and cut to `console_width()`. The message is often associated with the start of a calculation.
`msg_done`	The message to use when the message is cleared, when the calculation finishes successfully. If `.auto_close` is `TRUE` and `.auto_result` is `"done"`, then this is printed automatically when the calling function (or `.envir`) finishes.
`msg_failed`	The message to use when the message is cleared, when the calculation finishes unsuccessfully. If `.auto_close` is `TRUE` and `.auto_result` is `"failed"`, then this is printed automatically when the calling function (or `.envir`) finishes.
`.keep`	What to do when this status bar is cleared. If `TRUE` then the content of this status bar is kept, as regular cli output (the screen is scrolled up if needed). If `FALSE`, then this status bar is deleted.
`.auto_close`	Whether to clear the status bar when the calling function finishes (or `.envir` is removed from the stack, if specified).
`.envir`	Environment to evaluate the glue expressions in. It is also used to auto-clear the status bar if `.auto_close` is `TRUE`.
`.auto_result`	What to do when auto-closing the status bar.

Details

Use cli_status_clear() to clear the status bar.

Often status messages are associated with processes. E.g. the app starts downloading a large file, so it sets the status bar accordingly. Once the download is done (or has failed), the app typically updates the status bar again. cli automates much of this, via the msg_done, msg_failed, and .auto_result arguments. See examples below.
