regex - vim 正则表达式 : deleting character based on position

Question

这类似于问题 VIM: insert or delete data based on position

我正在尝试替换(不仅仅是插入)文件中每一行位置 7 处的所需文本。根据上述问题的解决方案中提供的正则表达式，我尝试了:

a. %s/\%=7c/text/  (failed error message - illegal character)
b. %s/\%7c/text/g   (says correct amount of lines / changes were made BUT blank space is still there after "text")
c. %s/\%7c/text/ (same as b)

Answer 1

/%7c 将在字符 7 处插入

您希望您的匹配项如下，以便它包含下一个字符:

%s/\%7c./text/
