flay 2.14.3

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.

  • Uses path_expander, so you can use:

    • dir_arg – expand a directory automatically

    • @file_of_args – persist arguments in a file

    • -path_to_subtract – ignore intersecting subsets of files/directories

  • Skips files matched via patterns in .flayignore (subset format of .gitignore).

  • Totally rad.
