vscode-arcadia

Getting Started

The quickest way to get going is to install the latest *.vsix file from the releases: v0.0.1 into VSCode: code vscode-arcadia-0.0.1.vsix

To run from source, clone the repo somewhere & open the root folder in VSCode. Run the extension in an Extension Development Host by pressing F5, or clicking Debug > Start. This runs the compiled extension.js file in the root folder.

Ensure Unity is up & an Arcadia project is loaded. Then in VSCode ⌘-shift-p and run Arcadia: REPL - Start.

Once the REPL is active, you can

• Arcadia: REPL - Send Line (ctrl+, l)
• Arcadia: REPL - Send Selection (ctrl+, s) or
• Arcadia: REPL - Send File (ctrl+, f) to send the current line, selection or file to the REPL respectively. Note that the extension automatically activates when VSCode detects current language as Clojure. So if you have a Clojure file open but no REPL yet, you can simply send the line/selection/file and the REPL will be started for you.

There is currently no in-REPL editing available, but you can open an empty file & use it as a scratch buffer. The REPL doesn't care what syntax the file is set to, but you would need to set it Clojure to get syntax highlighting obviously.

Development

To make changes or just build fresh from source, run lein cljsbuild once (or auto for continuous compilation);

NOTE: it took some fiddling to get a ClojureScript working in a VSCode extension.

I mostly followed the non-Figwheel parts of this, but I found that the Google Closure library didn't load properly (specifically, provided namespaces got attached to goog.global but not attached to the global goog var).

The trick to get it working was :optimizations :simple combined with :output-wrapper true. The other requirements are specifying :main and calling (set! *main-cli-fn* -main) from that namespace as documented on the ClojureScript NodeJS wiki page.
