trans / reflect.rb
Created February 2, 2014 17:08
Very simply implementation of object reflection.
# NOTE: This code was part of Ruby Facets standard library, but
# it has been deprecated in favor of more sophisticated
# implementations, such as the `instance` and `mirror` gems.
module ObjectSpace
# Reflection ensures that information about an object
# is actual according to Ruby's Kernel definitions, just
# in case such methods have been overridden.

trans / binbahn.sh
Created February 18, 2013 15:38
Add paths in ./bin to $PATH. Seemed like a neat idea --but not so much.
export ROOTPATH="$PATH"
function cd() {
builtin cd "$@"
for f in ./bin/*
do
export PATH="$f:$ROOTPATH"
done
}

trans / nilcomparable.rb
Created May 2, 2012 06:04
Make NilClass comparable
# This tiny framework simply makes nil comparable, such that
# all things (except itself) are greater than it.
#
# The main effect is this:
#
# nil <=> any_object #=> -1
#
# To enable a class to compare against nil (reverse of the above),
# simply prepend a nil comparsion into the #<=> method of that class.
# For example:
