COBOL language compiler to Javascript. Work in Progress
Via npm using (Node.js)[http://nodejs.org]:
npm install cobolscript
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);
