How do I see the Reach compiler's intermediate outputs?

Question

I run my programs with reach run and it creates build/index.main.mjs, which contains compiled bytecode, but I want to see (for example) the intermediate solidity file that it generates before compiling it all the way into bytecode.

Answer 1

You can use reach compile to perform only the compilation step, and to access compiler-specific options such as the --intermediate-files flag, which will dump a bunch of intermediate files including build/index.main.sol.

reach compile --help has more instructions. Technically the compiler is a program called reachc but reach compile runs a docker container for you containing the compiler. So you should translate any usage messages saying reachc to mean reach compile.
