PureScript Quickstart

gistfile1.sh

## This is a quickstart tutorial for PureScript. Unlike with other tutorials, you don't need
## any build-manager (Grunt etc.) installed globally. We will use locally-installed Gulp.
##
## Prerequisites:
## - cabal (Haskell package manager)
## - npm (Node package manager)
## You will find both of them in your OS' repository.


## install PureScript compiller

$ cabal update
$ cabal install purescript

## create a project directory

$ mkdir /some/where/hello
$ cd /some/where/hello

## create "Makefiles"

$ cat >package.json <<EOF
{
  "name": "hello-purescript",
  "version": "0.0.1",
  "description": "Hello PureScript!",
  "license": "MIT",
  "devDependencies": {
      "gulp": "3.5.2",
      "gulp-purescript": "0.4.2"
  },
  "scripts": {
      "build": "gulp ps-build"
  }
}
EOF

$ cat >gulpfile.js <<EOF
var gulp = require('gulp');

var purescript = require('gulp-purescript');

gulp.task('ps-build', function(){
  return gulp.src('src/**/*.purs').
         pipe(purescript.psc({main: "Main", module: ["Main"]})).
         pipe(gulp.dest('build'));
});
EOF

## source file(s)

$ mkdir src
$ cat >src/Main.purs <<EOF
module Main where

import Debug.Trace

main = do
  trace "Hello sailor!"
EOF

## install dependencies (gulp, gulp-purescript) into node_modules directory

$ npm install

## build .js file in build/ directory

$ npm run build

## run generated .js file

$ node build/psc.js
Hello sailor!
