Compiler CLI

[julian-hartl]

Detailed title

Motivation

To make it easier to compile a fusion program, we should think about building a cli that interacts with our compiler.
Possibly included features:

• Compile a fusion program from a file
• Transpile to C

Necessary Steps

• Move compiler to a crate and polish public interface
• Implement reading from a file instead of hardcoding input in compiler binary
• Create cli that transforms input into calls to the compiler api and outputs results

Possible Challenges

• Exposing the correct functionality in the compiler api
