LintFu

Lint-Fu uses some very basic static analysis tricks to find bugs in your Rails app. It produces a report (HTML format by default) explaining what it found.

Although Lint-Fu was built for Rails applications, it is modular and extensible and rules can be developed for any framework or toolkit, or even for Ruby code in general.

Lint-Fu’s capabilities are limited to semantic and structural analysis of the code; it does model data or control flow. This means it spots a *very small* subset of all potential bugs that it knows how to look for. Furthermore, it will sometimes report false positives.

Example

$ gem install lint_fu $ cd ~/my_project $ lint_fu
