Compiling and running in OCaml

I'm new to OCaml and I would like to know how can I write an ocaml code into a file and then compile it to run it whenever I want. Now I'm using OCaml by typing ocaml in the mac or linux terminal and writing the code, but when I'm done and I close the software I lose all the work.

If you are using Jane Street's Core, you should consider using the command corebuild to compile, which includes a bunch of defaults after ocamlbuild:

ocamlbuild \ -use-ocamlfind \ -pkg core \ -tag "ppx(ppx-jane -as-ppx)" \ -tag thread \ -tag debug \ -tag bin_annot \ -tag short_paths \ -cflags "-w A-4-33-40-41-42-43-34-44" \ -cflags -strict-sequence \ "$@"

I got this here.

I'm thinking this tutorial - Compiling OCaml projects might help. It describes the basics of compiling OCaml. It discusses ocamlc and ocamlopt compilers in depth and other compiler tools.

There're plenty of options, but the easiest one (to my opinion) is to use ocamlbuild. If you have your code in file program.ml, then 

ocamlbuild program.native

will compile your program into a native binary, so that you can run it as simple as:

./program.native

There is also a shortcut that allows you to compile and run a program as one action:

ocamlbuild program.native --

You can pass arguments to your program after the -- sign.

If your program consists of more than one file, that's not a problem, as ocamlbuild will scan it, and automatically build all dependencies in a correct order.

If your program requires external libraries, then you can specify them with a -pkg or -pkgs option. Like this:

ocamlbuild -pkg lwt program.native
