TROLL syntax suport

TROLL a dice programming language

TROLL is a "language for specifying dice-roll mechanisms" {@see http://hjemmesider.diku.dk/~torbenm/Troll/}.

Leveraging the syntax, or a subset of it, would allow the dice roller to conditionally handle D&D Critical Hits or Kids on Bikes' Explosions

While you can download TROLL as a command-line binary, you need to have Moscow ML installed (:-1:) & run it in a terminal. Besides, we want to eventually VISUALIZE the dice rolls, we only want to borrow the syntax feature-set, and run the program in browser.

Challenges

The language design for TROLL to produce an executable and a dice-rolling web-app's needs differ.

• Using a TROLL binary, you pass in a dice-roll mechanic and it will roll it for you.
• Using the web-app, we would want to SHOW the dice-roll, and if needed pass the result back (to handle conditions/loops).
• TROLL doesn't have syntax for Damage Type annotations
• TROLL doesn't have annotations for dice-color/-id.

I'm looking into how to write your own programming language parser. I'll just post links here that seem like they might be helpful.

Peggy seems to satisfy the parsing needs, the hard part is just porting the syntax manually.
