Demonstrate what happens if a user attempts to add to modify the PATH variable
using the withenv action.
$ . ./helpers.sh
This path is system-specific so we need to be able to remove it from the output.
$ DUNE_PATH=$(dirname $(which dune))
$ make_lockdir
Make some packages so that the test package can have dependencies:
$ cat >dune.lock/hello1.pkg <<'EOF'
> (version 0.0.1)
> EOF
$ cat >dune.lock/hello2.pkg <<'EOF'
> (version 0.0.1)
> EOF
Printing out PATH without setting it:
$ cat >dune.lock/test.pkg <<'EOF'
> (version 0.0.1)
> (build
> (system "echo PATH=$PATH"))
> EOF
$ dune clean
$ PATH=$DUNE_PATH:/bin build_pkg test 2>&1 | sed -e "s#$DUNE_PATH#DUNE_PATH#"
PATH=DUNE_PATH:/bin
Setting PATH to a specific value:
$ cat >dune.lock/test.pkg <<'EOF'
> (version 0.0.1)
> (build
> (withenv
> ((= PATH /tmp/bin))
> (system "echo PATH=$PATH")))
> EOF
$ dune clean
$ PATH=$DUNE_PATH:/bin build_pkg test 2>&1 | sed -e "s#$DUNE_PATH#DUNE_PATH#"
PATH=/tmp/bin
Attempting to add a path to PATH replaces the entire PATH:
$ cat >dune.lock/test.pkg <<'EOF'
> (version 0.0.1)
> (build
> (withenv
> ((+= PATH /tmp/bin))
> (system "echo PATH=$PATH")))
> EOF
$ dune clean
$ PATH=$DUNE_PATH:/bin build_pkg test 2>&1 | sed -e "s#$DUNE_PATH#DUNE_PATH#"
PATH=/tmp/bin:DUNE_PATH:/bin
Try adding multiple paths to PATH:
$ cat >dune.lock/test.pkg <<'EOF'
> (version 0.0.1)
> (build
> (withenv
> ((+= PATH /tmp/bin)
> (+= PATH /foo/bin)
> (+= PATH /bar/bin))
> (system "echo PATH=$PATH")))
> EOF
$ dune clean
$ PATH=$DUNE_PATH:/bin build_pkg test 2>&1 | sed -e "s#$DUNE_PATH#DUNE_PATH#"
PATH=/bar/bin:/foo/bin:/tmp/bin:DUNE_PATH:/bin
Printing out PATH without setting it when the package has a dependency:
$ cat >dune.lock/test.pkg <<'EOF'
> (version 0.0.1)
> (depends hello1 hello2)
> (build
> (system "echo PATH=$PATH"))
> EOF
$ dune clean
$ OCAMLRUNPARAM=b PATH=$DUNE_PATH:/bin build_pkg test 2>&1 | sed -e "s#$DUNE_PATH#DUNE_PATH#"
