Multiquine: final (4)

Context
Previous post  already presented the CS code template.
Now, here is the JS one

/*BOOTSTRAP*/
(function(language){
 var quote = String.fromCharCode(34), backslash = String.fromCharCode(92), newline = backslash + String.fromCharCode(114) + backslash + String.fromCharCode(110);
 var data =
 {
/*DATA*/
  cs: "CS_CODE_PLACEHOLDER",
  js: "JS_CODE_PLACEHOLDER",
  bf: "BF_CODE_PLACEHOLDER",
/*CODE*/
 };

 if(!language) language = 'js';
 var code = data[language];
 var bootstraps =
 {
   js: 'JS_BOOTSTRAP_PLACEHOLDER',
   cs: 'CS_BOOTSTRAP_PLACEHOLDER',
   bf: 'BF_BOOTSTRAP_PLACEHOLDER',
 }
 var res = bootstraps[language]
 switch(language)
 {
  case 'js':
   for(var i in data) res += ' ' + i + ': ' + quote + data[i].replace(new RegExp('\\\\', 'g'), backslash + backslash).replace(new RegExp(quote, 'g'), backslash + quote).replace(new RegExp(newline, 'g'), backslash + 'r' + backslash + 'n') + quote + ',\r\n';
   break;
  case 'cs':
   for(var i in data) res += ' data.Add(' + quote + i + quote + ', ' + quote + data[i].replace(new RegExp('\\\\', 'g'), backslash + backslash).replace(new RegExp(quote, 'g'), backslash + quote).replace(new RegExp(newline, 'g'), backslash + 'r' + backslash + 'n') + quote + ');\r\n';
   break;
  case 'bf':
   for(var i in data)
   {
     for (var j = 0; j < i.length; j++) { if (i.charCodeAt(j) == 13) continue; res += "+".repeat(i.charCodeAt(j)); res += '>'; }
res += '>';
for (var j = 0; j < data[i].length; j++) { if (data[i].charCodeAt(j) == 13) continue; res += "+".repeat(data[i].charCodeAt(j)); res += '>'; }
res += '>';
   }
   res += '\r\n';
 }
 res += code;
 console.log(res);
})()

Not really different from the C# version... Now, here is the BF one:

Hum. Hum. Sigh...
Ok. Let's analyze.

• Bootstrap: leave some free space.
• Data: write "cs", leave a cell, write CS DATA (placeholder), then write "js", leave a cell, write JS DATA (placeholder), and finally write "bf", leave a cell, write BF DATA (... ?)
• Code: read input
• No entry : that's BF. Write BF bootstrap (>>>>), then go the the first data cell, copy data declaration (leave a cell when needed), go to BF part of the data and print as text
• Input = "c" : that's CS. Write CS bootstrap, then go the first data cell, write '      data.Add("', then language name, then '", "', then language code (from data), by replacing " by \", \ by \\ and line breaks by \r\n. Finally, go to CS part of the data and print as text (change line breaks to real line breaks)
• Otherwise: that's JS (and globally same as CS...)

The final part to our quine implementation would be to create a generation tool (that read templates, and inject bootstraps / code into each template to create final codes).

That's what I did, but it's clearly out of scope for this post.

Code - BF

This one is really long... So, please generate it from either JS or CS code :)

Note

I strongly suggest NOT TO USE the online interpreter (nor any interpreter actually) to try the BF code. I yo're using Ubuntu, you can use the BF package (if you're on any other Linux distribution, you can use the same package by building the source - it even works on Mac OSX).

And if you're using Windows, then you can download Cydia, and compile the BF sources as well
