I have the same requirement to have a clojurescript-form in my
clojure-environment that I want to evaluate in the browser…
To make the following code-snippet work, you're supposed to have a browser-repl
session running, and start a new repl-session on that same JVM from where you
invoke the following forms to execute either javascript-code or
clojurescript-forms in the browser.
---
user=> (require 'cljs.repl)
nil
user=> (require 'cljs.repl.browser)
nil
user=> (cljs.repl.browser/browser-eval "alert('No Way!')")
{:status :success, :value ""}
user=> (def my-repl-env {:port 9000, :optimizations :simple, :working-dir
".lein-cljsbuild-repl", :serve-static true, :static-dir ["." "out/"],
:preloaded-libs []})
#'user/my-repl-env
user=> (def my-env {:context :statement :locals {}})
#'user/my-env
user=> (#'cljs.repl/eval-and-print my-repl-env my-env '(js/alert "Yes Way!"))
nil
nil
user=>
---
The public function "cljs.repl.browser/browser-eval" seems to allow you to send
javascript code as a string to the browser to execute over the existing
browser-repl connection.
The private function "cljs.repl/eval-and-print" will take a clojurescript form,
compile it to javascript and send it to the browser for execution. The
"my-repl-env" and "my-env" values are artifacts needed that are normally only
available within the context of the function.
My apology for this huge&ugly hack… please see it as a proof of principle.
There may be much more elegant solutions available… I've only scratch the
surface of understanding how this clojurescript repl works in detail.
-Enjoy, FrankS
