The **cli** package is used for progress reporting by several packages, notably tidyverse packages. For instance, in **purrr**, you can do: ```r y <- purrr::map(1:100, \(x) Sys.sleep(0.1), .progress = TRUE) ``` to report on progress via the **cli** package as `map()` is iterating over the elements. Now, instead of using the default, built-in **cli** progress bar, we can customize **cli** to report on progress via **[progressr]** instead. To do this, set R option `cli.progress_handlers` as: ```r options(cli.progress_handlers = "progressr") ``` With this option set, **cli** will now report on progress according to your `progressr::handlers()` settings. For example, with: ```r progressr::handlers(c("beepr", "rstudio")) ``` will report on progress using **beepr** and the RStudio Console progress panel. To make **cli** report via **progressr** in all your R session, set the above R option in your ~/.Rprofile startup file, e.g. ```r if (requireNamespace("progressr", quietly = TRUE)) { options(cli.progress_handlers = "progressr") } ``` _Note:_ A **cli** progress bar can have a "name", which can be specified in **purrr** function via argument `.progress`, e.g. `.progress = "processing"`. This name is then displayed in front of the progress bar. However, because the **progressr** framework does not have a concept of progress "name", this is silently ignored when using `options(cli.progress_handlers = "progressr")`.
