Motivation for this change
Given a
nix-shell
withocamlPackages.core
onOCAMLPATH
,utop
is unable to load Core.Std. The error was:This is because the wrapper script inserts a literal
$OCAMLPATH
into the$OCAMLPATH
environment variable, rather than expanding the existing value.This has not received extensive testing, but does solve my immediate problem. I'd like to get feedback from @vbgl or @FlorentBecker. Would also like to test on Linux at least, possibly NixOS.
