Locate an OSRM Lua profile (e.g. car.lua) in a host installation

By default OSRM ships profiles for "car", "bike" and "foot" in a profiles/ directory alongside the binaries. This function will try to locate osrm-routed on the PATH, resolve symlinks, and look first for a profiles/ directory next to the binary (as placed there by osrm_install()). If that fails, it looks for sibling directories share/osrm/profiles and share/osrm-backend/profiles. IF that fails, it will try to fall back on /usr/local/share/osrm/profiles,/usr/local/share/osrm-backend/profiles, /usr/share/osrm/profiles, and /usr/share/osrm-backend/profiles.

Usage

osrm_find_profile(profile = "car.lua")

Arguments

profile

A single string, the name of the Lua profile file (e.g. "car.lua"). Defaults to "car.lua".

Value

The normalized filesystem path to the profile.
