Expose cljs.core/Cons in SCI config (#142 )

This allows (instance? cljs.core/Cons x) to work in Scittle code. The Cons type exists in the compiled ClojureScript runtime but was not exposed by name in SCI's symbol table. Libraries like Trove need this for type checking in their const-form? function.
Enable customizing the nrepl websocket port (#141 )

 # Loading JS libraries
 Since `v0.7.28` scittle allows to load libraries from the global enviroment.
 This means you can load a library in a `<script>` tag and use it via `:require` in scittle.
 An example:
 ``` html
 <html>
  <head>
    <script src="https://cdn.jsdelivr.net/npm/scittle@0.7.28/dist/scittle.js" type="application/javascript"></script>
    <script src="https://cdn.jsdelivr.net/npm/js-confetti@latest/dist/js-confetti.browser.js"></script>
    <script type="application/x-scittle">
      (require '["JSConfetti" :as confetti])
      (.addConfetti (confetti.))
    </script>
  </head>
  <body>
  </body>
 </html>
 ```
 ## ES modules
 The async nature of ES modules makes them a litte bit more difficult to work
 with in scittle. You need to disable automatic evaluation of script tags first
 using `scittle.core.disable_auto_eval()`.  In a `module` type `<script>` tag you
 can then load ES modules, attach them to the global object and manually invoke
 `scittle.core.eval_script_tags();` when setup is completed.
 ``` html
 <html>
  <head>
    <script src="https://cdn.jsdelivr.net/npm/scittle@0.7.28/dist/scittle.js" type="application/javascript"></script>
    <script>scittle.core.disable_auto_eval()</script>
    <script type="module">
      import confetti from "https://esm.sh/canvas-confetti@1.6.0"
      globalThis.JSConfetti = confetti;
      scittle.core.eval_script_tags();
    </script>
    <script type="application/x-scittle">
      (require '["JSConfetti" :as confetti])
      (confetti)
    </script>

 Note that the nREPL server connection stays alive even after the browser window

 ### Custom host address
 By default, the browser will connect to a websocket on the same host as it is loaded
 from, using `window.location.hostname`. If you need something else you can specify
 that setting the window variable `SCITTLE_NREPL_WEBSOCKET_HOST` like so:
 ``` html

FrankS	f72c1c163a	Expose cljs.core/Cons in SCI config (#142 ) This allows (instance? cljs.core/Cons x) to work in Scittle code. The Cons type exists in the compiled ClojureScript runtime but was not exposed by name in SCI's symbol table. Libraries like Trove need this for type checking in their const-form? function.	2025-12-09 22:11:25 +01:00
