Last active August 29, 2015 14:17
Converts a Ruby object into a hash. This is not intended for object serialization or mapping, but instead for saving the information contained in an object to a document database, JSON file, etc...
require 'yaml'
require 'json'
# The Ruby object called 'objie' contains information
# that need to be saved in a document database. 'objie'
# may or may not contain nested objects
yaml = objie.to_yaml
# Alternatively: yaml = YAML::load('objie.yml')
# Remove the Ruby object's YAML header

Compiles most of the useful information in a git log into a chronologically-ordered tab-delimited list using pretty formatting and a combination of shell commands.
# Requires GNU's implementation of sed, which is provided by default on Linux.
# If you are on a Mac try installing gnu-sed using Homebrew and replace
# all instances of `sed` with `gsed` in the script.
# Sets the date format to iso8601. Change it if you need to.
# Note that several fields may contain invalid characters and the script
# does not check for that. You may have to use an encoding detector to
# impose the right encoding on the concerned fields.

Compiles most of the useful information in a git log into a chronologically-ordered validated JSON array using pretty formatting and Ruby's JSON library.
# Requires Ruby's JSON gem, or any other gem with compatible interface.
# The JSON output, thus, is necessarily valid.
# Supports nested hashes (just one level of nesting).
# Tries to validate all ...date and ..time fields using Ruby time.
# The script removes all linefeeds=newlines from all the fields.
# Sets the date format to rfc2282 as it is easy to parse in Ruby.
# You can also use the git_log function programmatically to receive a Ruby hash.
