我有一个很长的字符集，大约1000个字符长，没有任何空格。我可以在vim中将它们整齐地分成64个字符的行。例如，
我想转换一个这样的字符串：

感谢阅读。
答案 0 :(得分：4)
Qa64l<enter>q16@a:w
这将记录一个宏，在别名a下向右移动64次后按Enter键，并将运行该宏16次并保存文件。应该做你想问的事。
答案 1 :(得分：4)
如果调用外部命令没问题，可以使用fold命令：
fold -w64 file
要在vim中应用命令，您可以直观地选择字符串，然后：
:'<,'>!fold -w64 %
或者将命令应用于当前行：
:.!fold -w64 %
如果没有外部命令，这可能有效：
:.s#.\{64\}#&\r#g
从手册页：
替换中出现的＆符号（
&）将替换为与RE匹配的字符串
答案 2 :(得分：3)
:set textwidth=64
gqgq
:set textwidth=0
它将限制设置为最大行长度，重新调整当前行，并将限制返回到默认值（我假设您使用默认值）
