Missing something simple?

[Scott Hall]

Been working on this all day. Figure I must be missing something simple.

Basically I have three labels set in rules but inside the called ruby code I hookup it only has two of them set, ignoring the other. Here is the relevant rules:

  rule document

    contents:(dialog < RPGCode::DialogNode> / npc_dialog < RPGCode::DialogNode> / paragraph < RPGCode::ParagraphNode>)* break_ws* <RPGCode::DocumentNode>

  end

  rule npc_toon

    toon:([\w\s])+ ':' [ \t]*

  end

  

  rule npc_dialog

    (break_ws 2..)

    npc_toon 

    quote?

    dialog:(  

      !(break_ws 2.. / break_quote)

      paragraph_contents

    )+ 

    quote?

  end

But in RPGCode::DialogNode

dialog is set

contents is set

toon is NULL

I've tried changing things around many different ways. The idea is to capture a format like this:

Character: "Some Dialog Goes Here"

Where the quotes are optional. Getting character in one variable and the dialog inside the optional quotes as another. The last part works right now. 

contents label is used only for ParagraphNode but in DialogNode it is set as well (just doesn't do me any good).

I could resort to ruby code inside DialogNode but then that defeats the point of a tree parser. I'm sure I'm just missing something silly as this was the first time I worked with Treetop.

Any help is appreciated.

Scott,

Since no-one else has answered you, I'll try.

I would break these up differently - especially by moving each class out to a new rule.
It's quite hard to see what you intend when you do too much in one rule.

Did you intend both the "dialog" and the "npc_dialog" nodes to use RPG::DialogNode?
Even though npc_dialog includes one or more "dialog" nodes inside it?
You didn't share your "dialog" rule, so I can't tell.

npc_toon is a sequence, consistent of the toon sequence, a :, and zero-or-more space-or-tab.
As such the node returned has the "toon" accessor method defined.

However, in DialogNode, npc_toon will be set. You want to access "npc_toon.toon"
