Making a sort of standard for defining ascii art sprites

Today I've been reworking my text file "standard" for defining animated ascii sprites. '@' is for a new sequence, '&' is for a new frame in the sequence. The javascript object resulting is :

0: Object { name: "standing", frames: (1) […] }

1: Object { name: "standing_left", frames: (3) […] }

2: Object { name: "standing_right", frames: (3) […] }

3: Object { name: "crouching", frames: (1) […] }

4: Object { name: "crouching_left", frames: (3) […] }

5: Object { name: "crouching_right", frames: (3) […] }
