mruby-require causing issues with other mrbgems

[rjst]

Hi,

I'm using mruby-require, and although it appears to work fine, when using it, other mrbgems such as mruby-onig-regexp or mruby-eval stop working, just as if they weren't being included.

Am I doing something wrong or could this be a bug ?

regards,
Ricardo

Could you please show me your build_config.rb ? Probably, you specify mruby-onig-regexp after mruby-require in order. mruby-require should be last in order.

I tried, and it happens even if mruby-require is the last in the file.

Probably, you are using mruby-require. So try following on your mirb.

C:\temp\github\mruby>mirb
mirb - Embeddable Interactive Ruby Shell

This is a very early version, please test and report errors.
Thanks :)

Ok, I understand now. When using mruby-require additional mrbgems have to be required, which isn't the case when you aren't including it. Can I suggest that this is added to the documentation ? (I can do it if you'd like)

[mattn]

Cool, thank you. I'm not native speaker, so I think you are eligible than me.
