问题描述
当我使用IEx并像其他方括号或这样的拼写错误时,大多数情况下我会遇到语法错误.但是有些情况是这样的:
When I use IEx and make a typo like additional bracket or ", then most of the time I get a syntax error. But there are cases like this one:
iex(3)> Enum.each '12345', &(IO.puts(&1"))
...(3)> end
...(3)> )
...(3)> '
...(3)> end
...(3)> ""
...(3)> ... ? How to produce syntax error ?
...(3)>
BREAK: (a)bort (c)ontinue (p)roc info (i)nfo (l)oaded
(v)ersion (k)ill (D)b-tables (d)istribution
我无法犯语法错误,无法重新开始,必须重新启动整个IEx.是否有任何键盘快捷键或命令可跳过执行当前的iex(3)并转到下一个iex(4)?
I cannot make a syntax error and continue from scratch and I have to relaunch entire IEx.Is there any keyboard shortcut or command to skip performing current iex(3) and go to next iex(4)?
推荐答案
从 #iex:break
iex(1)> Enum.each '12345', &(IO.puts(&1"))
...(1)> ...
...(1)> #iex:break
** (TokenMissingError) iex:1: incomplete expression
