quib-console.js v0.1

This is a javascript HTML5 canvas console based on the excellent qb.js (http://stevehanov.ca/blog/index.php?id=92).

It translates the original QBasic console commands into methods of a class, and adds additional methods.

This version has HiDPI support. By using 2x-scaled images, it avoids HTML5 canvas fuzziness that otherwise occurs when scaling up bitmap images.

It supports all characters from code page 437. See also: https://en.wikipedia.org/wiki/Code_page_437. In particular, qb.js does not include smile characters, this does!

jQuery is a dependency.

Example

   const cons = new Console(2);    // 2 for 2x scaling (for HiDPI displays)
   document.getElementById('content').appendChild(cons.canvas);
   cons.print("Hello World");
