_str is a chainable library which aims to simplify string manipulation and handling.
_str will also keep an history of all the modifications made so it is easy to rollback or access the all history. It is also possible to store manipulation state which can later be retrieve individually or as a all (useful if you can have one chain for all your changes but need multiple formatted version of the original strings)
_str was started only few days ago and is not ready for release yet but you can follow it’s development and/or use it as it is if you wish (a fair amount of tests are done using Qunit already)
