ocaml

How to use as a script language like bash and python? It will be good that I can write a script in OCaml and directly invoke it.

如何使用作为bash和python等脚本语言？ 我可以在OCaml中编写脚本并直接调用它会很好。

For example, I write a script named “script.ml” and then I can invoke it directly by

例如，我编写了一个名为“ script.ml”的脚本，然后可以通过直接调用它

$ ./script.ml

Thanks!

谢谢！

Three helloworld scripts:

三个helloworld脚本：

script3.ml

script3.ml

#! /usr/bin/env ocamlprint_string "Hello world!n";;

script1.ml:

script1.ml：

#! /bin/ocamlprint_string "Hello world!n";;

script2.ml

script2.ml

#! /bin/sh# (*exec ocaml "$0" "$@"*) use "topfind";;print_string "Hello world!n";;

Remember to make the executable by

记得通过以下方式使可执行文件

chmod 755 script.ml

I prefer script3.ml. The script1.ml is straightforward, but it is bounded to /bin/ocaml for the ocaml command. The script2.ml is more complex, but use your environmental configuration for the location of the ocaml command.

我更喜欢script3.ml。 script1.ml很简单，但是对于ocaml命令，它已绑定到/bin/ocaml 。 script2.ml较为复杂，但是请使用您的环境配置作为ocaml命令的位置。

Also be aware that the overall source code is compiled in total first and then is executed. Hence, no execution happens if there is some , such as failures to compile the script. This is different from a bash script that will be executed by the interpreter until there is an error happens.

还应注意，总体源代码将首先全部编译，然后再执行。 因此，如果存在某些 （例如无法编译脚本），则不会执行任何操作。 这与解释器将在错误发生之前执行的bash脚本不同。
