Logo Implementation TODO

还没有人认领这个 Issue。

首先定位 JavaScript parser 和 turtle/canvas entry points，并以现有的 pensize 实现作为参考。将 unchecked parser commands 与 turtle shape 和 fill 工作分开，然后验证所选 command 是否按描述更改 canvas；只有当对应的 checklist 行为正常工作时，该 issue 才算完成。

由索引模型根据 Issue 内容生成。

Below is a list of things that still need to be implemented into the parser for the logo language:

circle > circle radius extend steps
dot > dot radius
pensize > pensize strokeSize
pencolor > pencolor color
fillcolor > fillcolor color note: this is dealing with custom shapes which we currently don't support yet
fill > fill true/false note: uses fillcolor to fill the shape if true
begin_fill > start shape
end_fill > end shape
write > write text note: this writes to the canvas as text ex "hello world"

Things to implement in turtle to add more features:

Dynamic stroke size so we can change it with pensize
Ability to create shapes and ill them with a solid color

--

Note: In Logo color sets both fillcolor and pencolor, this means we don't actually implement color properly yet
