The Prototype with the Split Personality
A tragedy in one act.
Sub-title: the case-insensitive file system strikes again.
Location: an OSX development machine.
Dramatis personae:
- Node.JS, a lightweight webserver
- HFS Plus, a file system that doesn't care if something's up or UP
- alpha.js, an innocent-looking file with a single prototype
- Developer, a simple monkey
Lights, camera, action.
Enter all.
alpha.js: exports.Class = function() {};
Developer:
js
var alpha = require('./alpha');
var AlPhA = require('./AlPhA');
HFS Plus: Hah, those both point to the same file!
Node.js: But they're still different modules. The names are not the same. 'a' != 'A'!
Developer (not having heard the previous two talking):
js
var obj = new alpha.Class();
console.log(obj instanceof alpha.Class);
console.log(obj instanceof AlPhA.Class);
Node.js: true, false
Developer: WTF? (commits suicide)
Curtain.
