问题描述
我是OCaml的新手，我想知道如何将ocaml代码写入文件，然后编译该文件以在需要时运行它.现在，我通过在Mac或Linux终端中键入ocaml并编写代码来使用OCaml，但是当我完成并关闭软件时，我将丢失所有工作.
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.
推荐答案
有很多选择，但最简单的选择(我认为)是使用.如果您的代码位于文件program.ml中，则
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
会将您的程序编译为本地二进制文件，以便您可以像以下那样简单地运行它:
will compile your program into a native binary, so that you can run it as simple as:
./program.native
还有一个快捷方式，使您可以作为一个动作来编译和运行程序:
There is also a shortcut that allows you to compile and run a program as one action:
ocamlbuild program.native --
您可以在--符号后将参数传递给您的程序.
You can pass arguments to your program after the -- sign.
如果您的程序包含多个文件，这不是问题，因为ocamlbuild将对其进行扫描，并以正确的顺序自动构建所有依赖项.
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.
如果程序需要外部库，则可以使用-pkg或-pkgs选项指定它们.像这样:
If your program requires external libraries, then you can specify them with a -pkg or -pkgs option. Like this:
ocamlbuild -pkg lwt program.native
