This is basically the standard pattern to define a method on the association proxies in rails so it's a relatively useful feature to support, hope this helps to diagnose, and if needed I can do more tests and provide more details

Rails?

If I run this on, for instance, a model file in a Rails 3.0 project on 1.9.2 I get a stacktrace. Is this expected behavior?

"simulate_require" breaks when requiring standard libraries

laser is failing for me when my files require standard libraries, such as ostruct and pathname. It appears to assume that these libraries are part of my application. The error originates in Laser::Analysis::ControlFlow::Simulation#simulate_require:
`simulate_require': No such file: ostruct (LoadError)

I'm running MRI 1.9.3. I ran $ gem install laser -v 0.7.0.pre1 --pre then $ laser --help and get:

I then $ gem install treetop, then $ laser and still get the same LoadError.

Doesn't compile on cygwin / windows

If I try to install this gem on cygwin / windows, I get a compile error (see below).
All other gems install fine on my machine.

$ gem install laser --prerelease

A ruby file with begin rescue statement seem to break this

try laser with this:

def tryAndRescue
begin
rescue
end
end

"rake build" gives Syck error

Maybe just me?

Security coverage

Hi,
I was looking for any Ruby static analysis tools that focussed on security. Laser came up as a static analysis tool, but it's not clear how much the tool focusses on security-testing. What's there level of security-scanning that it does?
Thanks,
Andrew

Simulate_require fails to require if extension is given

Using the test case:

a.rb:

class A
end

b.rb:

require './a.rb'
class B
end

Then running:
laser b.rb

I get the following stack trace:

Whereas if I remove the ".rb" from the require line this works. I've tracked the problem down to /lib/laser/analysis/control_flow/simulation.rb:357 where you assume the trailing ".rb" is never present.

Getting stacktrace for anything I do

Hi, I'm on Mac OSX Lion, using Ruby 1.9.2 (tried on p180 and p290)

When I try to do anything (ie laser -h) I wind up with a stack trace.

I want to recommend it to someone on the ML who is wanting static arity analysis in their tests, but I'm not comfortable recommending it if breaks for me.

Here is an example:

$ laser -h

Ripper problems on 1.8

Laser 0.7.0.pre2 has problems with regards to Ripper on Ruby 1.8.

With a fresh install:

agrimm@proline:$ ruby --version
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
agrimm@proline:$ ruby -S laser --version
/usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:in gem_original_require': no such file to load -- ripper (LoadError) from /usr/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:36:inrequire'

from /usr/local/bin/laser:19:in `load'
from /usr/local/bin/laser:19

Then once ripper is installed:

agrimm@proline:~$ ruby -S laser --version
/var/lib/gems/1.8/gems/ripper-plus-1.3.0/lib/ripper-plus.rb:2: ripper-plus requires Ruby 1.9+ (RuntimeError)

from /usr/local/bin/laser:19

Don't know if this is the case on trunk.

Move or get rid of metric_fu requirement on Rakefile line 58?

I'd like to build the gem without installing all of the developer dependencies. Does

require 'metric_fu'

need to be on line 58?
