Using it

pathxp have a very simple syntax, between {}, you can use T (top), B (bottom), L (left) or R (right), separated by ,, to define a path.

For example:

{T, L, B}

Represents a path goes up, left and finally, bottom.

To define multiples steps in the same direction, a number can be added in front of the direction symbol:

{2T, L, 3B}

This expression means two steps up, one left and 3 down.

Modifiers

Paths can also have modifiers, which is meant to define metadata about a path, they are done by adding their special identifier at the beginning of the expression, like [modifiers]{...}.

Available modifiers:

• Repeating (R): Means that the path should repeat.
• Infinite (I): Means that the path start again when it ends..
