Hi,

To which section would you add this project?

Thx!

Given the following scenario:

    Scenario: Constructing the PPM header
        Given c ← canvas(5, 3)
        When ppm ← canvas_to_ppm(c)
        Then lines 1-3 of ppm are
            """
            P3
            5 3
            255
            """

With a regexp of:

   -- @then ^lines (\d+)-(\d+) of ppm are$
   procedure Test (Start_Line, End_Line : Positive; Str : String);

Fails to generate with the following error:

Too many parameters (or not enough parenthesis groups) for step
   ^lines (\d+)-(\d+) of ppm are$

Remove the String parameter and it generates, but incorrectly. The multiline string is parsed by gnatbdd, but not passed as an extra parameter at the end of the function.

Using https://github.com/Lucretia/raytracer_challenge/blob/no-match/src/features/steps/tuples-steps.ads#L47 and #2

There are some issues I don't know how to work out.

1. gnatbdd copies the in out specification to the generated source. See below, I would put in String normally.

2. How do you handle return values? 'a' below?

   -- @given ^a ← tuple((\d+.\d+), (\d+.\d+), (\d+.\d+), (\d+.\d+))$
   procedure Given_A_Tuple (A : out Tuple; X, Y, Z, W : String);

Please add these to complete the project, gnatbdd-codegen.adb: 51
