Exporting error and empty .js file

Hello!

I'm trying to export an application from Pharo to Amber, and everything works find except when it has to write the .js file. It give me the following error + and empty .js file:

String>>streamContents:
a BlockClosure>>value:
a Exporter>>exportPackageDefinitionOf:on:
nil does not understand #name

node.js:134
throw e; // process.nextTick error, or 'error' event on first tick
^
Error: First argument needs to be a number, array or string.
at new Buffer (buffer.js:156:15)
at Object.writeFileSync (fs.js:485:12)
at /home/projects/Amber/Amber/mySrc/amberc.0ZLAPg/compiler.js:18557:8
at Array.forEach (native)
at Object.<anonymous> (/home/projects/Amber/Amber/mySrc/amberc.0ZLAPg/compiler.js:18549:11)
at Module._compile (module.js:402:26)
at Object..js (module.js:408:10)
at Module.load (module.js:334:31)
at Function._load (module.js:293:12)
at Array.<anonymous> (module.js:421:10)
Done.

Any idea?

Thanks,
Vanessa.

Re: Exporting error and empty .js file

Hello.

You have no package: in class definitions, probably; and exporter fails
for non-packaged classes.

You should work around this... one possibility is to patch
Class>>subclass:instanceVariableNames: to use some string like 'Sandbox'
instead of nil and restart the export/import.

Or patch the Class>>package to return something meaningful.

Thanks for your reply, Herby.
Finally my problem was that my category name had a "-" in its name, so it wasn't recognized. Everything works now.

Nops, sorry, my mistake. It was because the name of the category has different name than the . st file. I missed that instruction.

Thanks.
