You can modify enviroment variables from vimscript using
let $VARIABLE="value"
. You cannot export enviroment enviroment changes made by child process into
parent process neither in vimscript nor in other language: it is kernel level
restriction. If you see that something like
function SetVar() {
A="test"
}
A="test0"
echo $A
SetVar
echo $A
echoes `test0' and then `test' it only means that `SetVar' function is executed
inside the same shell process. Parsing text that script outputs to stdout is the
only way to modify vim enviroment.
