Simple path join and dirname functions for generic javascript
View path.js
// Joins path segments. Preserves initial "/" and resolves ".." and "."
// Does not support using ".." to go above/outside the root.
// This means that join("foo", "../../bar") will not resolve to "../bar"
function join(/* path segments */) {
// Split the inputs into a list of path commands.
var parts = [];
for (var i = 0, l = arguments.length; i < l; i++) {
parts = parts.concat(arguments[i].split("/"));
}
// Interpret the path commands to get the new resolved path.
