my development in ruby using editor that not have auto complete or intelisense, so when i need to know some of the methods is little bit difficult, I am not bother with it but after I have read discussion in our ruby mailling-list, Iam sure not only me have trouble like this , so after digging the ruby quiz, i got simple browser to check methods object of the core / lib / module.
this is html file and it contains 415 files, pretty big huh, this file can be browse using index / content and iframe. or pick the html file with classname on it.
anyway this not ready but for my need it ok.
*Update
