#   r2964 (Tyler):
#   * Started from http://svn.pluginaweek.org/trunk/plugins/ruby/module/module_creation_helper/ (Last Changed Rev: 320)
#   * Renamed :parent option to :namespace. (:parent is still allowed for backwards compatibility)
#   * Changed examples and tests to pass in the name as a symbol instead of a string.
#   * Made it so you can pass in the namespace as part of the name if you want: Module.create(:'Foo::Bar') instead of Module.create(:Foo, :parent => Bar)
#   * Added to the documentation
#   * Added new tests
#     * test_with_block_2
#     * test_nested_class_with_superclass_with_same_name
#     * test_referencing_a_namespace_that_isnt_defined
#     * test_creating_a_class_more_than_once
#     * test_using_return_value_of_one_create_within_another_create
#   * Added __FILE__, __LINE__ to class_eval so that error messages would be more helpful.

 breakpoint
 breakpoint 'Person#name'           # Identify it when it happens.
 breakpoint { @name }               # Default return value. 

• Access a no-config logfile for debugging.

 debug 'Database connection established'   # Look in ./debug.log 

• Trace expressions in that logfile.

 trace 'x + y'
 trace 'Process.pid'
 trace 'names', :pp                 # Pretty-print.
 trace 'page_structure', :yaml      # YAML representation.

[edit] Hoe

http://seattlerb.rubyforge.org/hoe/

Hoe is a simple rake/rubygems helper for project Rakefiles. It generates all the usual tasks for projects including rdoc generation, testing, packaging, and deployment.

• announce - Generate email announcement file and post to rubyforge.
• audit - Run ZenTest against the package
• docs - Build the docs HTML Files
• email - Generate email announcement file.
• install - Install the package. Uses PREFIX and RUBYLIB
• install_gem - Install the package as a gem
• multi - Run the test suite using multiruby
• package - Build all the packages
• post_blog - Post announcement to blog.
• post_news - Post announcement to rubyforge.
• publish_docs - Publish RDoc to RubyForge
• release - Package and upload the release to rubyforge.
• test - Run the test suite. Use FILTER to add to the command line.
• test_deps - Show which test files fail when run alone.
• ...

http://seattlerb.rubyforge.org/hoedown.html

Hoe is used in 6.96% of all gems!

Looks comparable in scope to Ratchets.

That's it exactly, well put.

[edit] Ratchets / Exacto

ProjectInfo

  The ruby extract runner can extract specific comments, in particular
  ==begin {label} ... ==end comments from a ruby script and run them
  as a stand-alone code that depends on the original script. By default
  it looks for comments labeled 'test'. So it is very good for running
  tests embedded directly into source, but can also be used for other
  code snippets.

setup.rb is the generic installer for ruby scripts/extentions. You can automate configuration and installation of your program package.

[edit] Dr. Nic's New Gem Generator

http://newgem.rubyforge.org/

http://drnicwilliams.com/2006/10/11/generating-new-gems/

The New Gem Generator is like the rails command for rails applications, but it creates the folders and starting files for a new gem. It’s called newgem.

Similar to hoe's 'sow' command?

[edit] debugprint

http://rubyforge.org/projects/debugprint/

[edit] Plugin systems

[edit] GemPlugin: Gem-Based Plugin System

http://mongrel.rubyforge.org/gem_plugin_rdoc/index.html

GemPlugin is a system that lets your users install gems and lets you load them as additional features to use in your software.

GemPlugin works by listing the gems installed, and doing a require_gem on any that have the right dependencies. For example, if a gem depends on "gem_plugin" and "mongrel" then it‘ll load as a Mongrel plugin. This makes it so that users of the plugins only need to gem install (and maybe config a bit), and plugin authors only need to make gems.

String manipulation / comparison / searching=

Example [2]:

 m = Sellers.new("pattern")

 m.match(["pattren","parent"])
 # => [2.0, 4.0]

 m.search("abcpattrendef")
 # => 2.0

[edit] Data structures: Trie

http://en.wikipedia.org/wiki/Trie

In computer science, a trie, or prefix tree, is an ordered tree data structure that is used to store an associative array where the keys are strings. [...] All the descendants of any one node have a common prefix of the string associated with that node, and the root is associated with the empty string.

The following are the main advantages of tries over binary search trees (BSTs):

• Looking up keys is faster. Looking up a key of length m takes worst case O(m) time. A BST takes O(log n) time, where n is the number of elements in the tree, because lookups depend on the depth of the tree, which is logarithmic in the number of keys.
• ...
