VIM – Vi IMproved 7.2(2008年8月9日，编译2010年7月12日02:29:33)

我在http://kovisoft.bitbucket.org/tutorial.html读了一本教程，并尝试启动麻省理工学院的REPL。不幸的是，我没有开始。

当我按“c”时，它开始一个终端窗口加载mit-scheme。 vim的REPL缓冲区中没有显示任何内容。终端中显示一些错误：

Listening on port: 4005
;netcat: "4005: inverse host lookup Failed: Unknown host"
;To continue,call RESTART with an option number:
; (RESTART 1) => Return to read-eval-print level 1.

2 error>

我读了源代码并修复了一些bug(关于netcat的参数等等)，这里是diff文件：

我重试了一些新的问题。

;The object #f,passed as the second argument to integer-add,is not the correct type.
;To continue,call RESTART with an option number:
; (RESTART 4) => Specify an argument to use in its place.
; (RESTART 3) => Return to SLIME top-level.
; (RESTART 2) => Close connection.
; (RESTART 1) => Return to read-eval-print level 1.

这是日志文件(swank.log)
