move_episode: Move an episode in the schedule

In zkamvar/sandpaper: Create and Curate Carpentries Lessons

Move an episode in the schedule

Description

If you need to move a single episode, this function gives you a programmatic or interactive interface to accomplishing this task, whether you need to add and episode, draft, or remove an episode from the schedule.

Usage

move_episode(ep = NULL, position = NULL, write = FALSE, path = ".")

Arguments

ep	the name of a draft episode or the name/number of a published episode to move.
position	the position in the schedule to move the episode. Valid positions are from 0 to the number of episodes (+1 for drafts). A value of 0 indicates that the episode should be removed from the schedule.
write	defaults to FALSE, which will show the potential changes. If TRUE, the schedule will be modified and written to config.yaml
path	the path to the lesson (defaults to the current working directory)

Examples

if (interactive() || Sys.getenv("CI") != "") {
  tmp <- tempfile()
  create_lesson(tmp)
  create_episode_md("getting-started", path = tmp, open = FALSE)
  create_episode_rmd("plotting", path = tmp, open = FALSE)
  create_episode_md("experimental", path = tmp, add = FALSE, open = FALSE)
  set_episodes(tmp, c("getting-started.md", "introduction.Rmd", "plotting.Rmd"),
    write = TRUE)

  # Default episode order is alphabetical, we can use this to nudge episodes
  get_episodes(tmp)
  move_episode("introduction.Rmd", 1L, path = tmp) # by default, it shows you the change
  move_episode("introduction.Rmd", 1L, write = TRUE, path = tmp) # write the results
  get_episodes(tmp)

  # Add episodes from the drafts
  get_drafts(tmp)
  move_episode("experimental.md", 2L, path = tmp) # view where it will live
  move_episode("experimental.md", 2L, write = TRUE, path = tmp)
  get_episodes(tmp)

  # Unpublish episodes by setting position to zero
  move_episode("experimental.md", 0L, path = tmp) # view the results
  move_episode("experimental.md", 0L, write = TRUE, path = tmp)
  get_episodes(tmp)

  # Interactively select the position where the episode should go by omitting
  # the position argument
  if (interactive()) {
    move_episode("experimental.md", path = tmp)
  }
}
