Yes, any single pipes, though that particular case I did not account for! It does indeed work here though it adds new lines (which is a separate general issue I’m dealing with).
These were my test cases so far (not super thorough):
defp run(string, func) do
result =
string
|> Sourceror.parse_string!()
|> func.()
|> Sourceror.to_string()
result <> "\n"
end
describe "unpipe" do
test "changes single pipes into inline calls" do
source = ~S"""
socket
|> assign(:foo, "foo")
"""
result = run(source, &unpipe/1)
assert result == ~S"""
assign(socket, :foo, "foo")
"""
end
test "leaves longer pipelines alone" do
source = ~S"""
socket
|> assign(:foo, "foo")
|> assign(:bar, "bar")
"""
result = run(source, &unpipe/1)
assert result == ~S"""
socket
|> assign(:foo, "foo")
|> assign(:bar, "bar")
"""
end
test "handles nested pipes" do
source = ~S"""
foo
|> bar()
|> baz(fn n ->
n
|> bar()
|> baz(fn m ->
m
|> foo()
end)
end)
"""
result = run(source, &unpipe/1)
assert result == ~S"""
foo
|> bar()
|> baz(fn n ->
n
|> bar()
|> baz(fn m ->
foo(m)
end)
end)
"""
end
