g" is a debugging tool similar to "p" but outputs object information to "growl" instead of STDOUT. It can be more useful than "p" in cases where rails outputs too much text to STDOUT, making it hard to find output from "p". The presentation demonstrates the usage of "g", how to install it with "gem install g", and concludes that "g" is a very useful debugging method.

- 5. This is my ?rst presentation in english.
- 6. I talk about a very useful method ＾g￣
- 7. You know ＾沿￣
- 8. It shows information of objects
- 9. ＾沿￣ is useful for debugging
- 10. But,
- 11. in some case ＾沿￣ is not useful.
- 12. For example,
- 13. rails
- 14. Rails outputs many texts to STDOUT.
- 15. like this
- 16. I use ＾沿￣ to output information of an object

- 19. In such case,
- 20. I use ＾g￣
- 21. What is ＾g￣?
- 22. ＾g￣ is like ＾沿￣
- 23. ＾g￣ outputs information of an object to ＾growl￣
- 24. like this
- 25. Usage
- 26. require ＾g￣ a = [1, 2, 3] ga
- 27. require ＾g￣ require ＾g￣ library a = [1, 2, 3] ga
- 28. require ＾g￣ require ＾g￣ library a = [1, 2, 3] ga and call ＾g￣
- 29. Demo
- 30. How useful it is!
- 31. How to install
- 32. It¨s very easy to install ＾g￣
