TooTallNatenode-function-name
Set the "name" property of Function objects
Very simple module. Sets the non-writable name property of Function
objects. In older versions of node, this functionality is exposed internally to
V8, but not exposed to JavaScript, so a native module is required. In newer
versions of node, function names can be redefined with Object.defineProperty,
which this module uses.
Note that unfortunately only String values are allowed.
NOTE: For users of node prior to
iojs@3.0.0, you'll need to use an earlier version of this module,function-name@1, which provides a C++ implementation.
Installation
Install with npm:
$ npm install function-name
Example
var set = require('function-name');
function test () {
throw new Error('blah');
}
console.log(test.name);
// "test"
// change the "name" property to 'foo'
set(test, 'foo');
console.log(test.name);
// "foo"
// spaces, and even usually illegal UTF8 chars, are allowed
set(test, ' ☃ ');
console.log(test.name);
// " ☃ "
// the newly set "name" also appears in stack traces!
test();
// Error: blah
// at ☃ (/Users/nrajlich/node-function-name/t.js:4:9)
