The way Jai does compiler options, using the Compiler module instead of command line arguments to the compiler, is good for use inside a project. When you're only compiling individual files, however, it is pretty clunky: you have to include effectively the script presented below in each program you write. To get round this, and speed up learning the language and testing it out, I've set up vscode to compile and run the current script with my chosen build options as one action. This involves a jai script (I say script because it never compiles to an exe) and a batch file. The setup is very basic right now, it could easily be expanded to allow you to pass in the exe name, etc. It works like this:
This is effectively a wrapper jai script which is compiled in order to compile the target program.
