Vim:用字符填充行

Question

如何在一行或多行的末尾重复添加字符,将行填充到特定列？

例如:(
'x'表示第40列,不是行上的字符;文本后面没有空格或制表符)

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

变

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

Answer 1

的组合\=,子匹配() ,以及重复() :

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

Answer 2

为了防止将来有人偶然发现这种情况,我有一种替代方式,我会使用哪种(我认为)更容易记住,在极少数情况下需要手动填充一些线.

输入文本:

Here are some words
They do not have equal length
I want to insert characters after them until column 40
How to do?

你输入什么:

gg                // Position cursor anywhere on first line you want to pad
q1$40A-<Esc>d40|q // Looks more complex than it is.
                  // Here, in English:
                  // 1. Record a macro in slot 1
                  // 2. Go to the end of the line, then *A*ppend a '-' 40 times
                  // 3. Delete from cursor position (which is still at the end of the line) to column 40
                  // 4. Stop recording
:1,4normal @1     // Repeat macro "1" for every line

输出文字:

Here are some words-----------------
They do not have equal length-------
I want to insert characters after t-
How to do?--------------------------

希望您能弄清楚如何调整命令的各个部分,使其完全符合您的要求.请注意,将截断超过所需列跨度的文本(在第3行上演示).
