# The Fasto Compiler (v1.0, 2022-04-27) This is the compiler for the Fasto programming language. The source code resides in the `Fasto` directory. Note that you need the .NET 6.0 SDK (*not* a Mono-based F#) installed on your machine, with the `dotnet` executable in your search path. Additionally, you should have `bash` to execute the various test scripts, and the Java Runtime Environment (full SDK not needed) to run the MARS simulator. To build the compiler, run `make` (or just `dotnet build Fasto`). To interpret, compile, or optimize a Fasto program, run `bin/fasto.sh`. To execute a compiled program (in MIPS assembly), run `bin/mars.sh`. To compile and immediately execute a Fasto program, run `bin/compilerun.sh`. To run all tests from the `tests` directory (or some other), run `bin/runtests.sh`. Use `-i` to run in interpreted mode, and `-o` to turn on the optimizations in the compiler.
