Does anyone know if it's possible to access Linux environment variables from within Pd? ie, in a message object? ...or would I have to write an external for this?
You could do it with pyext:
you can also do it in Ruby:
GridFlow::FObject.subclass("env",1,1) { def _0_bang; ENV.each {|k,v| send_out 0, [k,v.intern] } end def _0_get k v = ENV[k.to_s] if v then send_out 0, [k,v.intern] else post "No such environment var: %s ", k end end }
Try "get PWD" on Unix.
Or for that special purpose, one can also use this external instead (which just needs a bang):
GridFlow::FObject.subclass("pwd",1,1) {def _0_bang; send_out 0,Dir.pwd.intern; end}
note that the latter uses a systemcall whereas the former uses the environment-variables. cross fingers that both are synched. ;-)
