Cyclone has a similar architecture to other modern compilers:
TODO: this is hard to read. let's revisit original diagram and make that less wide so the exported PNG is not as wide either
<img src="images/compiler.png" alt="flowchart of cyclone compiler">
First, an input file containing Scheme code is received on the command line and loaded into an abstract syntax tree (AST) by Cyclone's parser. From there a series of source-to-source transformations are performed on the AST to expand macros, perform optimizations, and make the code easier to compile to C. These intermediate representations (IR) can be printed out in a readable format to aid debugging. The final AST is then output as a `.c` file and the C compiler is invoked to create the final executable or object file.
