vim 命令将文本重组/强制为 80 列 [英] vim command to restructure/force text to 80 columns

问题描述

我知道有一些方法可以使用 set textwidth(例如 Vim 80 列布局问题).我正在寻找的是类似于 =(缩进行命令)的东西，但要换行到 80.用例是有时你用 textwidth 编辑文本，在加入行或删除/添加文本后，它会出现外面包装不好.

I know there are ways to automatically set the width of text in vim using set textwidth (like Vim 80 column layout concerns). What I am looking for is something similar to = (the indent line command) but to wrap to 80. The use case is sometimes you edit text with textwidth and after joining lines or deleting/adding text it comes out poorly wrapped.

理想情况下，此命令将完全重新组织我选择的行并在添加短行的同时切掉长行.一个例子:

Ideally, this command would completely reorganize the lines I select and chop off long lines while adding to short ones. An example:

long line is long!  
short

运行命令后(假设换行是 13 列):

After running the command (assuming the wrap was 13 cols):

long line is  
long! short

如果使用真正的 vim 命令无法做到这一点，也许有一个命令行程序可以执行此操作，我可以通过管道将输入传输到其中?

If this isn't possible with a true vim command, perhaps there is a command-line program which does this that I can pipe the input to?

推荐答案

Set textwidth to 80 (:set textwidth=80)，移到文件开头(可以使用 Ctrl-Home 或 gg 完成)，然后输入 gqG.

Set textwidth to 80 (:set textwidth=80), move to the start of the file (can be done with Ctrl-Home or gg), and type gqG.

gqG 格式化从当前位置开始到文件末尾的文本.它会在可能的情况下自动连接连续的行.如果您不想将这两行连接在一起，您可以在两行之间放置一个空行.

gqG formats the text starting from the current position and to the end of the file. It will automatically join consecutive lines when possible. You can place a blank line between two lines if you don't want those two to be joined together.
