Cannot generate feature file with Rule: keyword

[GuillaumeMorinQc]

I cannot generate rst file from a feature file containing Rule: keyword . i'm using version 6.1.3 of sphinx_gherkindoc. Here an example :

Feature: Gherkin v6 Example -- with Rules
  Feature description line 1.

  Background: Feature.Background
    Given feature background step_1

  Rule: R1 (with Rule.Background)
    Rule R1 description line 1.

    Scenario: R1.Scenario_1
      When rule R1 scenario_1 step_1
      Then rule R1 scenario_1 step_2

The following error happened:

Traceback (most recent call last):

Parser failure in state steps, at line 7: "Rule: R1 (with Rule.Background)"

Is it somethting specific to configure for it to work? I was assuming that since behave parser covers gherkin version 6 that this simple file should work

[GuillaumeMorinQc]

Fix the problem using a dev version(1.2.7.dev0) of behave parser. But now nothing is generated after i hit a rule in the gherkin.

Is some work has been done to convert rules in rst ?

I am not aware of any work to convert to support "Rule" at this time... A PR to does that would be happily reviewed and shepherded through to merge though!

Given the extra level of nesting, I don't have a feel for how much work this might be, but I'm not against supporting it.
