Early in the 1970s，Stanford University graduate Rich Pattis think if we make the novice programmer in a relatively complex programming language,，Comparatively simple learning environment，Will contribute to the programming language teaching。This simple environment characterized by a variety of programming languages from abstraction。So he designed such a program environment，Allow students to teach a robot to solve simple problems。This robot is Karel[……]
Update it!
This update adds a branch，Goal is to create the "Next" function，In addition to repair the ugly side of the white block interface!
Currently no more modifications，run.swift file more refreshing，No more double thread it!
With an array of state of static storage Karel，Thanks for the banana king!
Adjust the speed of the great dream is within reach!?[……]
When you learn Java，Some details of the small problems tend to be very confusing，When in receive parameters, for example。
If your program needs to receive arguments in order to run，And you did not give the default parameters，That can cause this error：
