Atoms, prefixed with dot don't work as macros parameters
svetlyak40wt opened this issue · 5 comments
I wanted to create a macros:
(mac http_call method url ...body
`(do $http
(,method ,url) (.success (fn data (do ,...body)))))
To be used like:
(http_call .get "/api/items/"
(= $scope.items data))
which should produce code like this:
(do $http
(.get "/api/items/")
(.success (fn data
(do (= $scope.items data)))))
But compiler says:
Error: unexpected .get in possible modes: emptyhash | hash | list | quote | unquote | spread | spread | atom
Tested against: ( : ) ( isKey : ( ` , ... … isAtomString
Tokens: .get, "/api/permissions/", (, =, $scope.perms, data, ), ), (, http_get ...

If i remove dot from get
, then compilation succeed, but result is incorrect:
$http;
["/api/items/"]
.success((function(data) {
return ($scope.items = data);
}));
Thanks for noting. Right now, the only place where the compiler expects a free-floating .dot or [bracket] notation is in the beginning of a list in a do
:
(do str
(.trim))
You can work around this by using (get get)
instead of .get
. I suppose the compiler needs to be more liberal in where it allows property notation. Yet another ToDo.
Thank you, (get $http get)
works.
Think, nobody will work on this ever.
At some point, I'd like to write a blog post why. My opinion of Lisps was already low and went lower after some professional experience with Clojure.
It would be nice to read such post.
