I had seen that link before I posted but I could not to digest. That's why I posted here. It is not about setting the PATH. It is about getting the PATH. We are not going to ask every theide user to set "sudo launchctl config user path", aren't we? Moreover, the PATH is set. I can get it on terminal with 'echo $PATH' without problems. The questions is - how to get it programatically with upp the right way. getenv used inside ide is the wrong way.
P.S. for some reasons this doesn't work:

Sys("sh -c \'echo $PATH\'");
