I would like to write an OCaml function which takes a URL and returns a string made up of the contents of the HTML file at that location. Any ideas? Thanks a lot! Best, Surikator. I've done both of those things using ocurl and nethtml ocurl to read the contents of the URL (tons of properties here; this is the minimum), let string_of_uri uri = try let connection = Curl.init () and write_buff = Buffer.create 1763 in Curl.set_writefunction connection (fun x -> Buffer.add_string write_buff x; String.length x); Curl.set_url connection uri; Curl.perform connection; Curl.global_cleanup (); Buffer

Question, topic of discussion I am very interested in generation of command line shell scripting source code from code written in a more robustness-promoting, well-performant and platform-independent compiled language (OCaml, for instance). Basically, you would program in a compiled language to perform any interactions with the OS that you want (I would propose: the more complex interactions or ones that are not easy to do in a platform-independent way), and finally you would compile it to a native binary executable (preferably), which would generate a shell script that effects in the shell

I'm trying to learn OCaml through the Real World OCaml book. They have a guide by which I am supposed to install the Core package and utop. However, while I seem to be successfully installing both of these using Opam, neither of them works when I try to use them. I know that they're installed, because when I try to install them again, I get this message: $ opam install utop core [NOTE] Package utop is already installed (current version is 1.10). [NOTE] Package core is already installed (current version is 109.55.02). However, when I try to enter "utop" to start utop, it doesn't work. $ utop

Ocaml's standard library contains various modules: List , Map , Nativeint , etc. I know that interfaces for these modules are provided (e.g. for the List module ), but I am interested in the algorithms and their implementations used in modules' functions. Where can I find that? On your system: /usr/lib/ocaml/list.ml and other .ml files On the web: https://github.com/ocaml/ocaml/blob/trunk/stdlib/list.ml and other .ml files in https://github.com/ocaml/ocaml/tree/trunk/stdlib The List implementation is interesting to study. For example, the map function could be implemented like this: let rec

It seems as if there is no function in the standard library of type char -> string -> string , which insert a char in front of (or at the end of) a string . There are workarounds, e.g. by using String.make or String.blit . Is there an elegant way to do this? String.make and String.blit is a good way to do so, but they seem to be imperative. Personally I prefer to make infix functions using Char.escaped and string concatenation: let (^$) c s = s ^ Char.escaped c (* append *) let ($^) c s = Char.escaped c ^ s (* prepend *) The code from @pad is what I would use, because I like to treat strings

A period of intense googling provided me with some examples where people use both types of operators in one code, but generally they look just like two ways of doing one thing, they even have the same name tl;dr: The defining difference is that -> pipes to the first argument while |> pipes to the last. That is: x -> f(y, z) <=> f(x, y, z) x |> f(y, z) <=> f(y, z, x) Unfortunately there are some subtleties and implications that makes this a bit more complicated and confusing in practice. Please bear with me as I try to explain the history behind it. Before the age of pipe Before there were any
