My fascination with how things works in computers pushed me to build a simple interpreted "programming" language in form of a command line calculator. I based the project on flex/bison gnu tools - pretty archaic for modern standards, but as a C lang aficionado I felt comfortable while using them. Main functionalities of it included all math operations with operator precedence, defining variables, functions, control flow and loops. What I want to do next is to add capability to handle operations on strings. As usual you can find this project on my Github
