Example:
roll -i "1 d 20"
roll is a command line frontend for a custom library called "libroll".
The intent of this distinction is that libroll is meant to be integrated into other programs for easy implementation of complex calculations involving dice rolling with weird numbers.
libroll's approach is based on common Tabletop gaming Dice Notation systems, treating dice rolling as a mathematical operator with each die beginning at 1 and couting upwards to the specified amount of sides.
Currently these mathematical operators are being defined as "d" for normal rolls, as well as "d!" for rolls using exploding dice.
Both are right-to-left associative, meaning A d B d C is equivalent to A d ( B d C ) not ( A d B ) d C.
For more information about calculations/programming in libroll, see the Wiki.
What numbers are currently supported?
Libroll internally uses floating point numbers for dealing with point calculation, however if any non-integer number gets used in a dice roll, it will be treated like an integer (mainly because even I can't yet wrap my head around floating point randomness). Complex numbers aren't yet supported either.
What systems does it run on?
I mainly developed Roll for use within Linux terminals, occasionally compiling a Windows port. Since both Roll and Libroll are written in pure C(++) without any external dependencies however, it should be possible to compile it for anything under the sun. The program's beautifully tiny anyway ;P.
