monadic.js

Parser and Plugin for babel that provides haskell-like do-notation into javascript.

Should work with babel6

Setup

• Install monadic.js:

npm install --save-dev monadic.js

• Add plugin to babel's plugins list, and set monadic.js parser as babel's parser:

Part of webpack config (as an example):

//...
        loaders: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loader: "babel-loader",
                query: {
                    presets: [ "es2015", "stage-0" ],
                    plugins: [ "monadic.js/dist/plugin.js" ],
                    parserOpts: {
                        parser: "monadic.js/dist/parser.js"
                    }
                }
            }
        ]
//...
