funlinify

Inline javascript functions within a file (inline expansion).

How it works ?

The algorithm is pretty simple at this moment.

• Search all CallExpressions.
  • Search if the function body is reachable (same file/ast)
  • Prefix all variable arguments with a unique hash
  • Replace ReturnExpression in the function by an AssignamentExpression(=) and break till the end of the function body.
  • Replace the CallExpression with the given return variable.
  • Append argument conversion before the CallExpression
  • Append function before the CallExpression

It's pretty straight forward, don't do anything fancy. So is no error prone.

Gotchas

• Do not support nested CallExpressions (just one will be replaced)
• Do not inline functions outside given 'file/string/ast'
• Do not inline functions with expressions as arguments.

Usage

Browserify transform

 
output_stream = fs.createWriteStream('debug/js-2dmath-browser-debug.js');
 
require('browserify')('./index.js')
    .transform('funlinify')
    .bundle()
    .pipe(output_stream);
 

Direct

 
var file_contents = require("fs").fileReadSync("your-file.js");
require("funlinify")(file_contents, {}, callback(err, new_file_contents));
