rdoc :: http://docs.seattlerb.org/flay/
== DESCRIPTION:
Flay analyzes code for structural similarities. Differences in literal
values, variable, class, method names, whitespace, programming style,
braces vs do/end, etc are all ignored. Making this totally rad.
== FEATURES/PROBLEMS:
* Reports differences at any level of code.
* Adds a score multiplier to identical nodes.
* Differences in literal values, variable, class, and method names are ignored.
* Differences in whitespace, programming style, braces vs do/end, etc are ignored.
* Works across files.
* Add the flay-persistent plugin to work across large/many projects.
* Run --diff to see an N-way diff of the code.
* Provides conservative (default) and --liberal pruning options.
* Provides --fuzzy duplication detection.
* Language independent: Plugin system allows other languages to be flayed.
* Ships with .rb and .erb.
* javascript and others will be available separately.
* Includes FlayTask for Rakefiles.
* Skips files matched via patterns in .flayignore (subset format of .gitignore).
* Totally rad.
== KNOWN EXTENSIONS:
* flay-actionpack :: Use Rails ERB handler.
* flay-js :: Process JavaScript files.
* flay-haml :: Flay your HAML source.
* flay-persistence :: Persist results across runs. Great for multi-project analysis.
== TODO:
* Editor integration (emacs, textmate, other contributions welcome).
* Vim integration started (https://github.com/prophittcorey/vim-flay)
- Flays the current file on save, load, or on command
