Re^2: rel2abs of a path with env

Thanks. I wrote the following regex:

sub resolve_env_in_path {
    my ($path) = @_;
    $path =~ s/\$\{(\w+)\}/$ENV{$1}/g;
    $path =~ s/\$(\w+)/$ENV{$1}/g;
    return $path;
}

What do you think?

One thing your version silently strips out any undefined variables; using the `/e` modifier lets you have an expression rather than just a quoted string so you can do a bit of logic on the RHS of the substitution `...{ $ENV{$1} // qq{MISSING:$1} }e` (so you get an indication what's missing).
