Development

Development environment

The development environment has several dependencies:

To set up the environment:

1. Install each of these dependencies:

   • node.js
   • bower
   • pegjs

2. Clone this repository

3. Run bower install to install the remaining dependencies

Modifying the parser

1. Modify the grammar in the file assets/lambda.pegjs
2. Generate a new parser, by running the following command in the top-level directory:

```
pegjs assets/lambda.pegjs js/lambda-parser.js
```

1. pegjs assumes we're using node on the server, but wer' not. So, we need to modify the generated parser. a. Uncomment the first line, which looks something like:

   module.exports = (function() {
   

   b. Uncomment the last few lines, which look something like:

     return {
      SyntaxError: SyntaxError,
      parse:       parse
     };
   })();
