teal.code is an R library providing tools to store code and an execution environment associated with it. The features include:

• an object qenv for storing code and an execution environment which integrates well with shiny reactives for use in shiny applications whose outputs require reproducibility (i.e. the code used to generate them)
• ability to chain and join qenv objects together to provide fine-grained control over executed code
• automatic error and warning handling for executed code

teal.code also ships a shiny module that helps inspect the stored code as well as messages, warnings and error messages resulting from evaluation via shiny web application.
