In this section I describe in which situation you should use every option of the compiler.

Build and run program, Build program and Run program are meant to be used when you are just testing the compiler, or creating your own project. It uses the default entry_point and output specified by the code conventions of your current filetype.

Build solution is the option you use to tell Compiler.nvim the entry_point and output of your program (or many programs). You can do it by creating a .solution.toml file in your working directory. See here.

Instead of using a .solution.toml file, you can use make, cmake, gradle or any other build automation utility to compile and run your code. See here.
