`melange.emit` is attached to the package `mel-foo`, so it shouldn't be built
|
||
|
|
when building the other library
|
||
|
|
|
||
|
|
$ dune build -p my-ppx
|
||
|
|
|
||
|
|
It still builds everything normally with the alias
|
||
|
|
|
||
|
|
$ dune build @melange
|
||
|
|
$ ls _build/default/test/js-out/test/
|
||
|
|
test_entry.js
|
||
|
|
|
||
|
|
Now define a 3rd lib that we'll use to preprocess the melange.emit entries:
|
||
|
|
|
||
|
|
$ dune clean
|
||
|
|
$ cat > dune-project <<EOF
|
||
|
|
> (lang dune 3.8)
|
||
|
|
> (package (name my-ppx))
|
||
|
|
> (package (name mel-foo))
|
||
|
|
> (package (name my-ppx2))
|
||
|
|
> (using melange 0.1)
|
||
|
|
> EOF
|
||
|
|
$ mkdir ppx2
|
||
|
|
$ cat > ppx2/dune <<EOF
|
||
|
|
> (library
|
||
|
|
> (name my_ppx2)
|
||
|
|
> (kind ppx_rewriter) (libraries ppxlib)
|
||
|
|
> (public_name my-ppx2))
|
||
|
|
> EOF
|
||
|
|
$ touch ppx2/my_ppx2.ml
|
||
|
|
$ cat > test/dune <<EOF
|
||
|
|
> (melange.emit
|
||
|
|
> (package mel-foo)
|
||
|
|
> (target js-out)
|
||
|
|
> (preprocess (pps my-ppx2))
|
||
|
|
> (emit_stdlib false)
|
||
|
|
> (libraries mel-foo))
|
||
|
|
> EOF
|
||
|
|
|
||
|
|
we can still build my-ppx independently
|
||
|
|
|
||
|
|
$ dune build -p my-ppx
|
||
|
|
|
||
|
|
and fails if it can't resolve libraries to build the alias
|
||
|
|
|
||
|
|
$ dune build @melange -p my-ppx
|
||
|
|
