Transients in Ruby. Transients are a way to mutate an immutable object for a limited scope of changes and then make it immutable again.
class Object
def transient(&block)
dup.tap(&block).freeze
end
end
str = "hey".freeze
new_str = str.transient do |mutable_str|
mutable_str.upcase!

A pre-commit Git hook for preventing commits containing focus: true, debugger, binding.pry etc Based on a blog post I wrote http://jamie.ideasasylum.com/2013/02/preventing-the-stupid-mistakes-like-committing-focustrue/ (which in turn was based on someone else's script). This version allows you to easily setup new rules at the head of the script
#!/usr/bin/env ruby
spec_hits = []
checks = {
'_spec\.rb$' => ['focus:[:space:]*true'],
'\.rb$' => ['binding\.pry', 'debugger']
}
# Find the names of all the filenames that have been (A)dded (C)opied or (M)odified
filenames = `git diff --cached --name-only --diff-filter=ACM`.split("\n")
