pathCommands

Tokenizes an SVG path d string into its commands as written, without resolving them to absolute coordinates. Arc flags are read as single 0/1 characters, so compact arcs such as a1 1 0 011 1 tokenize correctly. Stops at the first character that is not a path command.

Basic example

Each command keeps its letter, so relative commands stay relative, and its numbers are grouped by segment when the command repeats. The arc’s flags are read as single digits, so a compact arc like a1 1 0 011 1 gives flags 0 and 1 and the endpoint 1, 1.

pathCommands("m0 0 10 10 20-5"); // m [[0,0],[10,10],[20,-5]]
pathCommands("M0,0a1 1 0 011 1");

Parameters
