Vim - 奇怪的行为

Question

I just recently deleted my .vimrc, and since I've added a few things back in and added some plugins I get this weird behaviour.

1. I click 'i' to place me in insert mode.
2. I type a character (any character)
3. Suddenly I get a newline break right where I started typing.

Extremely annoying! :) Any ideas on what this might be?

Answer 1

Sanity check. What happens if you run as vim -C (compatibility mode, behave like plain vi ) or vim -u NONE (don't load any initialization files or plugins)?

Answer 2

No, but you could start taking things out of your .vimrc one at a time and see if the problem goes away. Whatever was last removed, may have been the culprit (not always because it could be conflicting plugins).

Answer 3

There are quite a few things it could be given how customisable Vim is. However I think it might be your setting of 'textwidth'.

From Vim Help:

'textwidth' can be set to the maximum width for a line. When a line becomes too long when appending characters a line break is automatically inserted.

So check what 'textwidth' is set to and either increase it, or set it to 0 to disable this feature.

If this doesn't work, then try what everyone else said of just commenting out all your settings, checking this fixes the issue. Then slowly enabling settings again. Maybe use a binary search :)

Answer 4

You could back up your .vimrc file, remove the original and start up vim then create new vimrc:

:mkvimrc

Then you can start adding stuff from your old one and see which setting introduces the problem.

Same with plugins, move all your (not system) plugins out of your plugins directory and add one by one and see which one introduces the problem.

Answer 5

你的.vimrc一行一行注释，直到它按预期开始工作。

Answer 6

You could try using vim script debugging: "vim -D file". Then you could try to add some breakpoints, etc.

Answer 7

这要求将.vimrc之类的文件设置为源代码控制。

Answer 8

You could post your vimfiles + vimrc somewhere so others can take a look at it, and maybe determine the source of an error.

Saying that there is an error, without giving any concrete data, never resulted in anything.

Use some paste site, and post your vimrc, and a list of plugins (usually people use pretty much the same ones ... from www.vim.org).
