osrm.backend (version 0.2.0)

osrm_which: Locate the OSRM Installation Used by osrm.backend

Description

Resolves the osrm-routed executable available on the current PATH (or the override provided via options(osrm.routed.exec)). Runs osrm-routed --version to verify availability, then prints the directory containing the executable together with the backend version reported by osrm-routed so you know what will be used in the current session.

Usage

osrm_which(quiet = FALSE)

Value

A list with components executable (full path to osrm-routed), directory (its parent folder), osrm_version (character vector of non-empty lines emitted by osrm-routed --version), and the raw processx::run result in logs.

Arguments

quiet

Logical; if FALSE (default), prints information about the located installation. If TRUE, suppresses printed output and only returns the information as a list.

Examples

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

  # check which OSRM installation will be used
  osrm_which()

  osrm_uninstall(
    dest_dir = install_dir,
    clear_path = TRUE,
    force = TRUE,
    quiet = TRUE
  )
}
# }
