While I love Node.js, I've found myself missing some functions. Things like recursively deleting/chmodding a directory (or even deep copying a directory), or even a basic line reader, shouldn't need to be re-invented time and time again.
That said, here's my attempt at a re-usable solution, at least until something more formalized gets integrated into Node.js (hint hint). wrench.js is fairly simple to use - check out the documentation/examples below:
npm install wrench
var wrench = require('./wrench'),
util = require('util');
// Recursively delete the entire sub-tree of a directory, then kill the directory
wrench.rmdirSyncRecursive('my_directory_name');
// Recursively chmod the entire sub-tree of a directory
wrench.chmodSyncRecursive('my_directory_name', 0755);
// Deep-copy an existing directory
wrench.copyDirSyncRecursive('directory_to_copy', 'location_where_copy_should_end_up');
// Read lines in from a file until you hit the end
var f = new wrench.LineReader('x.txt');
while(f.hasNextLine()) {
util.puts(x.getNextLine());
}
It should be noted that these are all currently synchronous operations.
