$runtime is not defined

[ghost]

Opal example works fine for me but if I try precompile ruby code (browser.rb) I get this error:
$runtime is not defined (in precompiled browrser.rb, I called browser.js)

I use HTML code like this:

<script src="../../extras/opal.js"></script>
<script src="../../extras/opal.dev.js"></script>    
<script type="text/javascript" src="browser.js"></script>

I've tried removing opal.dev.js, I've tried rquery.js (from homepage) but I always get the same error.

Any help? Thank you in advance.

Hey. How are you compiling the code (ruby tools? altjs.org?)? Also, can you paste the code that it is generating?

[ghost]

I compile browser.rb with this command:
opal compile browser.rb > browser.js

I've updated my browser.js file: https://gist.github.com/1020856

Of course, I use opal edge version (git clone).

Thank you again. Great piece of work!

Ooooops! I closed this issue by mistake!

Ahhhhh, it seems that the compile command misses out a little piece of code. Basically that outputted code should be inside a function which defines the $runtime variable. I'll go fix that and update you here once its all working again.

So I've just committed a fix for this at 102a979. You need to pull the latest changes, regenerate opal.js or opal.dev.js (either will do) and recompile your file with that same command you used before. The generated code is now properly wrapped and will be run directly. Let me know if this solves the issue.

Great!
Now it works OK.

Opal rocks! Thank you!

Glad Its working. Just as a follow up, I've just pushed b1f5a1f to master which adds some more build options to the compile command. In your use case, it has the same effect except that the generated code will now be written directly to the output file which it assumes from your input filename, so the following should work for you:

bin/opal compile browser.rb

Which outputs the code to browser.js.
