Testing the empty alias

|
|
$ cat > dune-project <<EOF
|
|
> (lang dune 3.17)
|
|
> EOF

Building the empty alias does nothing
|
|
$ dune build @empty
|
|
|
|
We should check that a user has not added anything to an empty alias:
|
|
$ cat > dune <<EOF
|
|
> (rule
|
|
> (alias empty)
|
|
> (action
|
|
> (echo "I should not be added!")))
|
|
> EOF
|
|
|
|
For versions prior to 3.20 this does not fail:
|
|
$ dune build @empty
|
|
I should not be added!
|
|
|
|
Also creating an alias called empty is allowed prior to 3.20:
|
|
$ cat > dune <<EOF
|
|
> (alias
|
|
> (name empty)
|
|
> (deps foo))
|
|
> EOF
|
|
$ cat > foo
|
|
|
|
$ dune build @empty
|
|
|
|
For versions 3.20 and after these should fail:
|
|
|
|
$ cat > dune-project <<EOF
|
|
> (lang dune 3.20)
|
|
> EOF
|
|
|
|
$ cat > dune <<EOF
|
|
> (rule
|
|
> (alias empty)
|
|
> (action
|
|
> (echo "I should not be added!")))
|
|
> EOF
|
|
|
|
$ dune build @empty
