Vim:用字符填充行 [英] Vim: padding out lines with a character

问题描述

如何在一行或多行的末尾重复添加一个字符，将行填充到特定列?

How can I repeatedly add a character at the end of one or more lines, padding out the line(s) to a specific column?

例如:
('x' 代表第 40 列，不是行上的字符；并且文本后没有空格或制表符)

For instance:
('x' represents column 40, not a character on the line; and there are no spaces or tabs after the text)

line one                               x
line two                               x
line three                             x
line eleventy-billion                  x

变成

line one ------------------------------x
line two ------------------------------x
line three ----------------------------x
line eleventy-billion -----------------x

推荐答案

\=, submatch() 和 repeat():

:%s/\v^.*$/\= submatch(0) . " " . repeat("-", 39 - len(submatch(0)))
