Current directory (and also current env) can affect an expander,
|
||
|
|
and expander is in turn used to expand things in env.
|
||
|
|
|
||
|
|
Given that we only have a few string_with_vars in env, a reasonable
|
||
|
|
example is hard to come up with, but here is a contrived one.
|
||
|
|
|
||
|
|
$ echo '(lang dune 2.0)' > dune-project
|
||
|
|
$ cat > dune <<EOF
|
||
|
|
> (env
|
||
|
|
> (_
|
||
|
|
> (ocamlc_flags "%{inline_tests}")))
|
||
|
|
> EOF
|
||
|
|
|
||
|
|
$ dune printenv --root . . --field ocamlc_flags
|
||
|
|
(ocamlc_flags (enabled))
|
||
|
|
|
||
|

|

$ echo '(lang dune 2.0)' > dune-project
|
||
|
|
$ cat > dune <<EOF
|
||
|
|
> (env
|
||
|
|
> (_
|
||
|
|
> (ocamlc_flags "%{inline_tests}")
|
||
|
|
> (inline_tests ignored)))
|
||
|
|
> EOF
|
||
|
|
|
||
|
|
$ dune printenv --root . . --field ocamlc_flags
|
||
|
|
(ocamlc_flags (ignored))
