In salim-b/pkgpurl: Facilitate Authoring R Packages in the R Markdown File Format

NOTES

This file is not included in the source package because of the .nopurl suffix in its filename.
The chunks below have to be manually executed in order to regenerate the package data.
asciicasts are only regenerated manually because their generation takes a considerable amount of time. To regenerate an asciicast, manually run its code chunk, rebuild the package and finally re-build the vignette(s) where it's included.
After asciicasts are regenerated (and stored as JSON files under inst/asciicasts/), the package must be rebuilt in order to actually include the updated JSON files.
The asciicast player width of 116 chars (cols = 116L) is optimized for the current pkgdown layout of rpkg.dev.

Record and write asciicasts

`SOME_ASCIICAST`

fs::dir_create("inst/asciicasts")
tmp_file <- fs::file_temp(ext = "R")

c('SOME_R_CODE_TO_CAST() %>%
  readr::write_lines(file = tmp_file)

asciicast::record(script = tmp_file,
                  title = "SOME TITLE",
                  startup = quote(options(cli.width = 115L)),
                  timeout = 180L,
                  typing_speed = 0L,
                  rows = 50L,
                  cols = 116L,
                  speed = 1.0) %>%
  asciicast::write_json(path = "inst/asciicasts/SOME_ASCIICAST.json")

fs::file_delete(tmp_file)
