CobolScript

COBOL language compiler to Javascript. Work in Progress

Installation

Via npm using (Node.js)[http://nodejs.org]:

npm install basicscript

Usage

Reference in your program:

var cobolscript = require('cobolscript');

To compile a source code:

var program = cobolscript.compileProgram('display "Hello, world".');

To compile a file:

var program = cobolscript.compileProgramFile('./hello.cob');

To run a compiled program:

program.run(cobolscript.getRuntime());

Some programs need a runtime object that provides helper functions, i.e. display implementation. In the above example, a console-oriented runtime object is obtained.

In web samples, a runtime that uses request, response is used:

http.createServer(function(req, res) {
    program.run(cobs.getRuntime({ request: req, response: res }));
}).listen(8000);

Development

git clone git://github.com/ajlopez/CobolScript.git
cd CobolScript
npm install
npm test

Samples
