From 74e9234a87f6fac98900201a481696b31df2bdab Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Gustavsson?= Date: Thu, 2 Mar 2017 15:03:34 +0100 Subject: dialyzer, observer: Use portable lookup of home directory Use init:get_argument(home) to find the location of the home directory. That will work on all platforms (including Windows). Note that the run-time system will fail to start if HOME (or the equivalent on Windows) is not set. Therefore, it can be assumed that init:get_argument(home) will not fail.
