简介
OCaml，最早称为 Objective Caml，是 Caml 编程语言的主要实现，由 Xavier Leroy，Jérôme Vouillon，Damien Doligez，Didier Rémy 及其他人于1996年创立，OCaml 是开放源代码项目（LGPLv2.1）。
OCaml 一般用于编译器、程序分析、金融交易、虚拟机等方面。它是 Jane Street 的核心语言，重点是用它写实时交易系统会很赚钱。
F#，Microsoft .NET平台上 OCaml 风格的编程语言。
ML 家族的两个主要的方言是 Standard ML 和 OCaml。

OCamlverse Documenting everything about OCaml
完成第一个OCaml程序，Hello World!，创建test.ml文件，包含：
let _=print_endline "hello world!"
编译 test.ml
ocamlc test.ml -o test // Byte-code编译 或 ocamlopt test.ml -o test // Native-code编译 ./test
REPL
$ ocmal 或 $ utop // eval $(opam config env) utop # let () = print_endline "Hello OCaml World!";; Hello OCaml World!
类型
utop # (1, "str1", 2.);; // 元组tuple
- : int * string * float = (1, "str1", 2.)
utop # [1; 2; 3];; // 列表list
- : int list = [1; 2; 3]
utop # [|1; 2; 3|];; 数组array
- : int array = [|1; 2; 3|]
utop # type vec2 = { x : float; y : float };; //记录record
type vec2 = { x : float; y : float; }
常见问题
Error: Unbound module Core
vim ~/.ocamlinit 加入以下内容，并重新运行utop
#use "topfind" #camlp4o #thread #require "core.top" #require "core.syntax"
-bash: ocamlfind: command not found
eval $(opam config env)
