Introduction

Running the examples

All the examples in this guide can be found in the example/ directory in the Luv repo. You can run them locally by cloning the repo:

git clone https://github.com/aantron/luv.git --recursive
cd luv

and then running make examples. Note the examples require OCaml 4.08 or higher.

To run a specific example, say, delay.ml, run:

dune exec example/delay.exe

You can also pass arguments to examples with this syntax:

dune exec example/http_get.exe -- google.com /

Using the repo for experiments

You can quickly experiment with Luv by writing your own code in example/. Let’s say you add a file, example/test.ml. Add it to the names list in example/dune:

(executables
 (names
  hello_world
  ; ...
  sigint
  test)     ; <-- here!
 (libraries luv))

…and then run it like any other example:

dune exec example/my_test.exe

If you have utop installed, you can also run:

dune utop

inside the Luv repo, to access the Luv API in a REPL. For example, try dune utop, and, when you get the REPL prompt, run Luv.Env.environ ();;
