In this test we test the translation of a package with a build-env field into a dune lock
file.
$ . ./helpers.sh
$ mkrepo
Make a package with a build-env field
$ mkpkg with-build-env <<'EOF'
> build-env: [ [ MY_ENV_VAR = "Hello from env var!" ] ]
> build: ["sh" "-c" "echo $MY_ENV_VAR"]
> install: ["sh" "-c" "echo $MY_ENV_VAR"]
> EOF
$ solve with-build-env
Solution for dune.lock:
- with-build-env.0.0.1
The lockfile should contain a setenv action.
$ cat dune.lock/with-build-env.pkg
(version 0.0.1)
(install
(withenv
((= MY_ENV_VAR "Hello from env var!"))
(run sh -c "echo $MY_ENV_VAR")))
(build
(withenv
((= MY_ENV_VAR "Hello from env var!"))
(run sh -c "echo $MY_ENV_VAR")))
This should print the value given in the build-env field.
$ MY_ENV_VAR="invisible" build_pkg with-build-env
Hello from env var!
Hello from env var!
