Once you understand ocaml, you will feel that it is a very magical language, but the first step is very difficult to learn it. I hope this small tutorial will make things easier.First, ocaml is not a structured language and belongs to the function language family. Pure function language does not provide a Loop Mechanism (you need to use recursion to complete the loop), variables cannot be changed, and other

Now we will spend some time looking at the actual OCaml program at a higher level. I want to teach
anonymous functionsIn a functional language, a function is a class citizen, and it should be able to support "literal" like other types (int,float,string, etc.), which is the anonymous function.1 );; int int = 17;; int 8As you can see, anonymous functions can be used instead of the function's location.Some functions require an argument that is another function, but can also be passed in with an anonymous function. Like what:Utop # List.map ~f: (Fun x->x+1) [1; 2; 3 ];; int list = [234]Don't wor
1. ocaml Overview
Starting with ocaml 3.05, there are no less than three portsObjective caml for MS windows available:-A Native WIN32 port, built with the Microsoft development tools;-A Native WIN32 port, built with the cygwin/mingw development tools;-A port consisting of the UNIX sources compiled under the cygwinUnix-like environment for Windows.
Here is a summary of the main differences between these port
If the OPAM is configured in the CentOS environment, OCaml, Core, utop are installed, then you can start learning OCaml.Follow the footsteps of Real world Ocaml to learn. The HTML version is available online.Let's take a look.Common numeric calculationsOCaml care about types, floating-point numbers and integer type operators cannot be mixed.3 4 ;; int 7 3.1 4.2 floatint3.1 4.2;; float 7.3 Integer dig
Assuming you have installed the Opam with SU permissions on the CENTOS7, return to normal permissions below. Use Opam to install something else.Opam installation of things, by default in the ~/.opam directory, it does not have permissions to change the system directory of things.If there is a problem with the configuration, it is simple. Delete ~/.opam directory, everything NEW!1. Opam InitInitialize the environment, go all the way yes.Test whether the criteria for success, see if the environmen
Mac OS X textmate running OCaml code prompt error uncaught exception:invalid_argument ("Fl_package_base.query")
Workaround, modify the ~/library/application\ support/textmate/managed/bundles/ocaml.tmbundle/support/ocamlmate/run_script.rb file
@ocamlc = argv[0] #修改为: @ocamlc = File.basename (argv[0])

Generally, you can use SQL to delete or stop a job.
Remove JOB: remove
Stop JOB: broken
First pass
Select * from user_jobs;
Find the job id, and then call
Dbms_job.broken or
Dbms_job.remove to remove and stop. The SQL statement is as follows.
Take removing a job as an example.
