Is there a static analysis tool for Python, Ruby,

问题:

I am looking for a static analysis tool for Python, Ruby, Sql, Cobol, Perl, PL/SQL, SQL similar to find bugs and check style. I am looking for calculating the line count, identify bugs during the development, and enforcing coding standard.

回答1:

Perl has Perl::Critic (and perlcritic.com)

回答2:

I use PyChecker and pylint as Python code checkers. However it seems that they get buggy when you use some modules (e.g., socket or pygame, IIRC).

回答3:

For Ruby, you're probably best served looking at this previous SO question:

https://stackoverflow.com/questions/286564/can-anyone-recommend-a-ruby-source-code-analyzer-something-like-pylint

which seems pretty thorough.

回答4:

Sonar has a PL/SQL plugin that is based on Toad CodeXpert code analyzer.

回答5:

See various static analysis tools from Semantic Designs.

These cover standard metrics for Java, C# and COBOL. There are also tools to detect duplicate code (clones) for many languages, including Python, Java, PL/SQL (from your list).

Finally, there is a style checker (coding standards checks) for COBOL (with optional Eclipse plugin) that offers refactoring support to fix some of the style errors.

I use Pylint for Python which was nicely integrated into Komodo by Brandon Corfman (if ActiveState's Komodo is your thing).
