regular expression is too big

[QuBiT]

Hi,

I am getting the following error:

regular expression is too big .... [a console window full of
expressions]

caused by

./features/step_definitions/pickle_steps.rb:64
--> Then(/^#{capture_model} should (?:be|have) (?:an? )?
#{capture_predicate}$/) do |name, predicate|

and (when removing (documenting out) that step on line 64)

./features/step_definitions/pickle_steps.rb:73
--> Then(/^#{capture_model} should not (?:be|have) (?:an? )?
#{capture_predicate}$/) do |name, predicate|

tested with pickle 0.3.0, 0.3.3, 0.3.4 on rails3.0.0.rc with cucumber
0.8.5 upgraded from rails2.3.5

The error is caused by "capture_predicate" which produces the regexp
(simple having to many different predicates for too many models ?!)

When I remove both steps everything is fine again.

How can I change this, so that I am able to use those steps?

additional info to the message above:

with rails2.3.5 this steps work without error on the same application.
(using factory_girl 1.2.4, pickle 0.3.0)

Hi there,

This is a problem that I'm working on with pickle.

The reason why the code constructs such an expression is to stop ambiguous step collisions for the should be <predicate> steps.

Until I come up with a general solution, you can try the following:

You can try replacing the #{capture_predicate} with something like (\w[\w ]+\w), but that is likely to cause ambiguous step problems.

If you do have this problem, there are two other things to try.

In Pickle.configure, try restricting the predicates to those you need:

Pickle.configure do |config|
config.predicates = %w(small? large? green?)
end

Or, if this is not appealing, replace #{capture_predicate} with "(\w[\w ]+\w)" (adding quotes around the above one)

This means you;ll have to rewrite these steps with quotes. ie.

Then the 2nd user should be activated

becomes

Then the 2nd user should be "activated"

The quotes should remove any ambiguous step clashes.

Let me know how you get on.

Cheers,
Ian

Thanks for your fast reply.

Currently I am not needing those steps (but as they are defined and
loaded, they caused that error) so I documented them out.

If I need them I will try your suggested workarounds.

Thanks and Cheers
