Either about:
- Targeting a specific platform (Clojure JVM, Clojurescript dev, or Clojurescript release)
- Transcending those platforms
See README for examples.

cljs?clj/s
(cljs? target)Is the target referring to Clojurescript? (Either :cljs/dev or :cljs/release).
Is the [[target]] referring to Clojurescript? (Either `:cljs/dev` or `:cljs/release`).
clojure?clj/s
(clojure? target)Is the target referring to :clojure?
Is the [[target]] referring to `:clojure`?
expand*clj/smacro
(expand* & clojure-form+)Also known as an "anonymous macro".
Whether in Clojure JVM or during Clojurescript compilation, the given forms are executed as Clojure JVM and the returned value is expanded just like when using a macro.
See README for a full example.

not-cljs-release*clj/smacro
(not-cljs-release*)Must be used within a macro.
Given a macro's &env and &form, throws if the target is :cljs/release.
Useful for forbidding specific features outside of development.
Thrown exception is an ex-info with a data map containing:
| Keyword | Meaning |
|---|---|
| :medium/forbidden | The first symbol extracted from the given form |
| :medium/form | The given form |
**Must be used within a macro.** Given a macro's `&env` and `&form`, throws if the [[target]] is `:cljs/release`. Useful for forbidding specific features outside of development.

targetclj
(target env)Passing a macro's &env, determines the target:
:clojure:cljs/dev:cljs/release
Passing a macro's `&env`, determines the target: - `:clojure` - `:cljs/dev` - `:cljs/release`
target*clj/smacro
(target*)Calls target. Meant to be used at the REPL, from Clojure/script.
Calls [[target]]. Meant to be used at the REPL, from Clojure/script.
when-compiling*clj/smacro
(when-compiling* & clojure-form+)Similar to expand* but any returned value is discarded.
Solely useful for any kind of side effect on the JVM regardless of the target platform.
Similar to [[expand*]] but any returned value is discarded. Solely useful for any kind of side effect on the JVM regardless of the target platform.
when-target*clj/smacro
(when-target* target-request & form+)Akin to the standard when macro, executes the given forms when the target matches
target-request (either a target or a collection of them for matching any).
Akin to the standard `when` macro, executes the given forms when the [[target]] matches `target-request` (either a [[target]] or a collection of them for matching any).
