converterclj/smultimethod
Platform specific converters.
Takes the env (from &env or platform keyword) and returns a converter function.
The converter function takes a symbol and returns the platform specific version of that symbol.
Platform specific converters. Takes the `env` (from `&env` or platform keyword) and returns a converter function. The converter function takes a symbol and returns the platform specific version of that symbol.
platformsclj/s
An atom containing the platform specific predicates. Is an map of predicates,
and their platform keyword value. The predicate should take a macro &env and return a
boolean. See https://clojure.org/guides/reader_conditionals for platform keywords.

symbolclj/s
(symbol env sym)Takes the target env (from &env or platform keyword), and a quoted symbol.
Transforms the symbol to platform specific symbol.
(symbol :cljs 'clojure.core.async) => cljs.core.async
Takes the target `env` (from `&env` or platform keyword), and a quoted symbol. Transforms the symbol to platform specific symbol. `(symbol :cljs 'clojure.core.async)` => `cljs.core.async`
transformclj/smacro
(transform quoted-form)Transforms the symbols in a quoted form to platform specific symbols.
Takes a quoted-form to be transformed. Use this in macros.
e.g. (defmacro go [& body](env/transform (async/go ~@body)))`
WARNING: Will throw StackOverflowError for deeply nested forms.
