// ==/UserScript==
// dice_concise / Based on Marcel Kossin's 'dice' RP Dice Simulator
//
// What is this?
//
// -- Marcel Kossin's notes: --
//
// I (mkossin) often Dungeon Master on our Neverwinternights Servers called 'Bund der
// alten Reiche' (eng. 'Alliance of the old realms') at bundderaltenreiche.de
// (German Site) Often idling in our Channel I thought it might be Fun to have
// a script to dice. Since I found nothing for irssi I wrote this little piece
// of script. The script assumes, that if a 'd' for english dice is given it
// should print the output in English. On the other hand if a 'w' for German
// 'Würfel' is given it prints the output in German.
//
// Usage.
//
// Anyone on the Channel kann ask '!roll' to toss the dice for him. He just has
// to say what dice he want to use. The notation should be well known from
// RP :-) Thus
//
// Write: !roll <quantity of dice>d[or w for german users]<sides on dice>
//
// Here are some examples
//
// !roll 2d20
// !roll 3d6
//
// OK, I think you got it already :-)
//
// Write: !roll version
// For Version Information
//
// Write: !roll help
// For Information about how to use it
//
// -- Makaze's notes: --
//
// [Changes in dice_concise:]
//
// Features added:
//
// [ ] Can add bonuses to the roll. e.g. "!roll 3d6+10"
// [ ] Output changed to one line only. e.g. "Makaze rolls the 3d6 and gets: 9 [4,
// 4, 1]"
// [ ] Corrected English grammar.
// [ ] Removed insults.
// [ ] Cleaner code with fewer nested if statements and true case switches.
// [ ] Errors call before the loop, saving clock cycles.
//
// Bugs fixed:
//
// [ ] Rolls within the correct range.*
//
// Edge cases added:
//
// [ ] Catch if rolling less than 1 dice.
// [ ] Catch if dice or sides are above 100 instead of 99.
//
// -----------------------------------------
//
// * [The original dice.pl rolled a number between 1 and (<number of sides> - 1)]
// [instead of using the full range. e.g. "!roll 1d6" would output 1 through ]
// [5, but never 6. ]
//
// -----------------------------------------
//
// Original script 'dice.pl' by mkossin.
//
// Updated and ported script 'dice_concise.js' by Makaze.
