Very simple module. Sets the, usually immutable, name
property of Function
objects. This functionality is exposed internally to V8, but not exposed to
JavaScript, so this native module is required.
Note that unfortunately only String values are allowed.
Install with npm
:
$ npm install function-name
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)
// at Object.<anonymous> (/Users/nrajlich/node-function-name/t.js:23:1)
// at Module._compile (module.js:449:26)

That's it!
