File-find 0.1.0

Ruby
1

Hi all,

I’m happy to announce the first release of file-find. This package is
meant as a replacement for the current ‘find’ module in the Ruby
standard library. It provides many more options for controlling the
behavior of your find operations.

It is modelled on the ‘find’ command typically found on Unix systems.

Example1:

Look for all .rb files changed in the last 24 hours

rule = File::Find.new(:name => “*.rb”, :ctime => 0)
rule.find{ |file| puts file }

Look for all text files owned by user id 23, don’t follow symlinks

rule = File::Find.new(:name => “*.txt”, :user => 23, :follow => false)
rule.find{ |file| puts file }

You can find install the file-find package as a gem, or grab the file
from the project page at http://rubyforge.org/projects/shards/. You
can also find it on the RAA.

Enjoy!

Dan

Woo! Thanks!
One question: what happens when you iterate over a directory you do
not have permission to read? Rio throws an exception and exits,
meaning the remaining files are skipped, which is not cool. I tried to
provide an option to skip forbidden directories, but Rio is a bit
convoluted.

It skips them. :slight_smile:

Can you find directories with this?

#!/usr/local/bin/ruby

require ‘rubygems’
require ‘yaml’
require ‘file/find’

finder = File::Find.new(:name => ‘*’, :path => ‘/etc’, :ftype =>
‘directory’)
finder.find{|d| p d}

–gives me nothing.

That would be a bug. Please file it on the RubyForge project page so I
don’t forget.

Nevermind about the bug report. It’s fixed in CVS. :slight_smile:

I just put out 0.2.0 today. This version adds “prune” and “perm”, as
well as fixes a bug where subdirectories weren’t being traversed.

Strange. I just tried a remote install and it worked fine. Try again
later. Perhaps you’ll need to delete your gem cache.

Rio does raise an exception when trying to read the contents of a
directory that one does not have permission to read. This behaviour is
due to the fact that Rio is a facade for the builtin class Dir – and
Dir raises an exception. Personally I think this behavior is
appropriate. Silently skipping unreadable directories is not always
desired

I tried to
provide an option to skip forbidden directories, but Rio is a bit
convoluted.

No additional option is required to get the desired behavior. Rio
allows control of which directories will be recursed into.

rio(‘adir’).recurse(:readable?).files(‘*.txt’) { … }

This will silently skip unreadable directories.
