使VIM函数返回没有缩进的文本 [英] Make VIM function return text without indent

问题描述

我想这个问题可以通过两种方式解决...

I guess this question could be taken in two ways...

1. (通用)-有没有一种方法可以为功能指定本地"设置(在功能调用后setlocal更改似乎仍然存在)...

1. (Generic) - is there a way to specify settings 'local' to a function (setlocal changes seem to persist after the function call)...

(特定)-我有一个从imap映射调用的函数(需要用户输入才能传递给该函数.如果我运行set paste或set noai | set nosi，则该函数可以完美运行

(Specific) - I have a function which gets called from an imap mapping (which takes a user input to pass into the function. The function works perfectly if I run set paste or set noai | set nosi either just before running my shortcut, or added into the function itself. The problem is, whichever way I do it, those setting changes persist after my function call.

基本上，我的工作流程是:

Essentially, my workflow is:

1. 在插入模式下，键入////，这时会提示我输入输入文本，然后输入并按Enter.

2. 该函数使用我的输入进行调用.我需要禁用缩进功能，返回我的字符串，然后重新启用先前的设置.该字符串只是这样的PHP块注释:

1. In insert mode, type //// at which point I get prompted for input text, which I enter and press enter.

2. The function is called with my input. I need the function to disable indenting, return my string and then re-enable the previous settings. The string would just be a PHP-block comment like this:

/**
 * Blah {INPUT TEXT}
 */

任何建议表示赞赏.我的脚本当前如下所示:

Any suggestions appreciated. My script currently looks like this:

function CommentInjector(txt)
  return "\/**" ."\<CR>"
  \    . " * foo " . a:txt . " bar " . "\<CR>"
  \    . " */"
endfunction
imap <silent> //// <C-R>=CommentInjector(input("Enter some text:"))<CR>

更新

设法弄清楚至少如何在...中转储注释...希望了解如何获取/恢复设置...

UPDATE

Managed to figure it out at least how to dump a comment in... Would appreciate knowing how to get/restore settings though...

function! CommentInjector(txt)
  set paste

  exe "normal! i/**\<CR>"
  \          . " * fooo " . a:txt . " bar\<CR>"
  \          . " */\<Esc>"

  set nopaste
endfunction

map <C-C><C-C><C-C> :call CommentInjector(input("Enter some text:"))<CR>

使用此功能，您可以按Ctrl + C 3次，在出现提示时输入文本，并且会写上漂亮的注释.它假定您在运行之前已禁用设置粘贴" ...

Using this you can just pres Ctrl+C 3 time, enter text when prompted and you get a nice comment written in. It assumes you had "set paste" disabled before running though...

推荐答案

既然您已经发布了更新，并且实际上只是在研究如何保存/恢复设置，所以我将给出一个通用的解决方案.

Since you've posted an update and are really just looking at how to save/restore settings, I'll give a general solution.

• 在函数开始时，保存设置的初始值:let save_paste = &paste
• 要对paste进行任何更改
• 将其恢复到最后:let &paste = save_paste

• At the start of your function save the initial value of the setting: let save_paste = &paste
• Make any changes to paste that you'd like to make
• Restore it at the end: let &paste = save_paste

在:help use-cpo-save的文档中可以找到有关此示例的内容，他们讨论如何保存和恢复cpoptions的值.

An example of this can be found in the documentation with :help use-cpo-save where they talk about saving and restoring the value of cpoptions.
