global doesn't apply to import

desm commented 9 years ago

Hi, I get the following error when trying to run the sample LiteScript blog-example-dns.lite.md:

$ git clone git@github.com:luciotato/LiteScript.git

When I remove the 'global' keyword, then the error message becomes:

Using the 'lite -s' flag, code generation is successful:

Then, when I try to run it, I get the following error:

This is because the 'run' method is no longer used. So simply removing ".run" from that line of code does the trick. Note that one needs to use a version of node >= 0.11 and that the '--harmony' flag is required.

I'm sorry for that. The nice+parallel example got neglected while I was focusing on the compile-to-c feature.

_Now the example is fixed, please try it_

Thanks for the detailed report.

The problem was:

That example was for LiteScript v0.5 or less (now we are at v0.8)
To unify compile-to-c and compile-to-js, along v0.7 a new constraint was added: to import a pure-js library you need an .interface.md file describing the module interface. (It can be automatically generated)
There were no .interface file for node's module "dns"

The solution:

I've used the mkInterface utility, to automatically create an .interface.md file from require('dns')

cd ~/LiteScript/devel/source/v0.8/utility 
lite -run mkInterface dns >dns.interface.md

After some tweaking, the interface for dns is now included in LiteScript/lib/interfaces

By fixing the import problem, also the correct "nicegen" is now imported.

Hi @luciotato , I'm sorry I never saw your reply until now. I have practically no recollection of this discussion. You can close the issue if you'd like.
