Usage

The recommended way to use Standard is with a top level open at the beginning of a file.

This will ensure all of the built-in modules are replaced.

open Standard;
String.toList("somestring")
->List.filterMap(~f=character => 
  Char.toCode(character)->Int.add(1)->Char.ofCode
)
->String.ofList

Automatic opening

To avoid having to write open Standard at the top of every file, you can pass a compiler flag to do this automatically for you. How this is configured depends on your build system.

With Bucklescript

In bsconfig.json edit the bsc-flags array to look like the following:

"bsc-flags": [
  "-open", 
  "Standard",
  // ...
]

With Esy

In package.json / esy.json edit the esy.flags array to look like the following:

"esy": {
  "flags": [
    "-open",
    "Standard"
  ],
}
