The Grain Compiler
Grain is a strongly-typed functional programming language built for the modern web by leveraging the brilliant work done by the WebAssembly project.
This language is still a work in progress, but be sure to stay tuned, or even contribute!
For more information about the language, visit grain-lang.org.
Building
Compiler
To build the compiler, have ocaml
(version >= 4.02.3), opam
, and jbuilder
installed
and on your PATH
.
Then, running make
will install any needed OCaml dependencies and build the
compiler.
Running make install
will symlink grainc
onto your PATH.
You can run the tests with make tests
.
Runtime
To build the runtime, have node
(version >= 9) and npm
(version >= 5) installed. Then,
cd runtime
npm install
npm run build
CLI
To make the CLI available on your path, have node
(version >= 9) and npm
(version >= 5) installed. Then,
cd cli
npm install
npm link --global
Running
To create a .wasm
file, run the following:
grainc /path/to/file.gr -o /path/to/output.wasm
For an example of how to run the file in JavaScript, look at the
files under script
.
You'll need to create a symlink from script/public/javascripts/grain-runtime.js
to the built file in runtime/dist/grain-runtime.js
, or you'll have to just copy it over to run the example.
Alternatively, you can use the CLI to run your program on Node:
grain test.gr
