This is the first installment of HashiCode, a blog post series where I go through the source code of HashiCorp tools to learn more about what happens behind the scenes when you interact with tools as a user. Disclaimer: this episode is referencing code from the Terraform codebase as of commit 43a7548. Becuase Terraform is a constanly evolving open source tool, the code is subject to change. However, the ideas expressed will largely remain the same.
