erlang - Escript: setting code path relative to script directory -


when try set relative code path in escript -pz this

#!/usr/bin/env escript %% -*- erlang -*- %%! -pz ../dir-of-some-beams

the path interpreted relative directory run escript from, renders useless setting path relative script location.

my current "workaround" using absolute path annoying since part of repository , don't want location dependent.

so how can set code path relative directory escript located in?

just found out myself:

at beginning of main add code this:

true = code:add_pathz(filename:dirname(escript:script_name())                         ++ "/../dir-of-some-beams"),

i recommend testing true whith these code functions, because easy type code:add_pathsz wants list of strings , returns ok, if pass string -- doesn't set code path single directory (which pretty annoying behaviour btw).
