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

• storing character literals as code,
• storing an execution environment,
• swapping the execution environment of the stored code,
• evaluating only parts of the stored code,
• means to execute code with a no-throw guarantee (errors demoted to warnings and messages stored for retrieval).

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.
