Ah, you probably want `declared` instead of `declaredInScope`. The latter only
works for the immediately enclosing scope and not the ones above it. The
documentation may not be very clear on that
[https://nim-lang.org/docs/system.html#declared%2Cuntyped](https://nim-lang.org/docs/system.html#declared%2Cuntyped).
import macros
template foo(body: untyped) =
block:
let inFoo {. inject, used .} = true
body
template bar(body: untyped) =
block:
let inBar {. inject, used .} = true
body
proc callApiFromFoo =
echo "Calling API with foo scope"
proc callApiFromBar =
echo "Calling API with bar scope"
template callApi =
when declared(inFoo):
callApiFromFoo()
elif declared(inBar):
callApiFromBar()
else:
echo "You can call API only in foo or bar scopes!"
proc foobar =
foo:
block:
callApi()
bar:
block:
callApi()
foobar()
Run
