invalid guardfile - no block given

[ElijahLynn]

Everything appears to be running fine but I am getting an annoying error (https://gist.github.com/3661622).

Any ideas?

Guardfile is this - https://gist.github.com/3661100#file_gistfile1.rb

This has nothing to to with Guard, the problem is (as the error message says), that with Ruby 1.8.7 the Find.find method must take a block. Only newer Rubies returns an enumerator:

$ rvm use ruby-1.9.3-p194
$ pry 
[1] pry(main)> require 'find'
=> true
[2] pry(main)> Find.find(Dir.pwd)
=> #<Enumerator: ...>
[3] pry(main)> ^D

$ rvm use ruby-1.8.7-p358
$ pry
[1] pry(main)> require 'find'
=> true
[2] pry(main)> Find.find(Dir.pwd)
LocalJumpError: no block given
from /Users/michi/.rvm/rubies/ruby-1.8.7-p358/lib/ruby/1.8/find.rb:39:in `find'
[3] pry(main)> ^D

So either use to a newer Ruby version or rewrite the Guard condition.

Even though this wasn't anything to do with Guard I want to let you know I very much appreciate your explanation and example, it is very helpful.

Thank you

You're welcome. Solving little puzzles like this is relaxing and it makes me a better Ruby programmer with every issue :P
