Examples

# \donttest{
if (identical(Sys.getenv("OSRM_EXAMPLES"), "true")) {
  install_dir <- osrm_install(
    version = "latest",
    path_action = "session",
    quiet = TRUE
  )

  # copy example OSM PBF into a temporary workspace to avoid polluting pkg data
  pbf_path <- system.file("extdata/cur.osm.pbf", package = "osrm.backend")
  osrm_dir <- file.path(tempdir(), paste0("osrm-", Sys.getpid()))
  dir.create(osrm_dir, recursive = TRUE)
  tmp_pbf <- file.path(osrm_dir, "cur.osm.pbf")
  file.copy(from = pbf_path, to = tmp_pbf, overwrite = TRUE)
  graph <- osrm_prepare_graph(tmp_pbf, overwrite = TRUE, threads = 1L)

  srv <- osrm_start_server(graph$osrm_job_artifact, port = 6000, threads = 1L)
  osrm_servers()
  osrm_stop(srv)
