vim中如何在单词两侧重复添加文本？

发布于 2024-11-12 04:10:30 字数 201 浏览 5 评论 0原文

我在 Python 脚本中有一堆局部变量引用，我想从字典中提取它们。因此，我需要将 foo、bar 等更改为 env['foo']、env['bar' ]等等。我是否需要编写正则表达式并匹配每个要转换的变量名称，或者是否有更直接的方法可以使用 . 命令重复？

您可以使用宏：一次性键入这些命令（留有空格以插入注释），

             " first move to start of the relevant word (ie via search)
qa           " record macro into the a register.
ienv['<esc>  " insert relevant piece
ea']         " move to end of word and insert relevant piece
q            " stop recording

然后，当您输入下一个单词时，只需按 @a 即可重播宏（甚至可以按 < code>@@ 之后重复上次重播）。

You can use a macro: type these commands in one go (with spacing just to insert comments)

             " first move to start of the relevant word (ie via search)
qa           " record macro into the a register.
ienv['<esc>  " insert relevant piece
ea']         " move to end of word and insert relevant piece
q            " stop recording

then, when you're on the next word, just hit @a to replay the macro (or even @@ to repeat the last replay after that).

有一种更简单的方法 - 您可以使用正则表达式搜索和替换。通过键入冒号进入 cmdline 模式，然后运行以下命令：

%s/\\(foo\|bar\|baz\\)/env['\1']/

将 foo、bar 和 baz 替换为您的实际变量名称。您可以根据需要添加任意数量的其他变量，只需确保使用反斜杠转义 OR 管道即可。希望有帮助。

There's an easier way - you can use a regex search and replace. Go into cmdline mode by typing a colon and then run this command:

%s/\\(foo\|bar\|baz\\)/env['\1']/

Replacing foo, bar, and baz with whatever your actual variable names are. You can add as many additional variables as you'd like, just be sure to escape your OR pipes with a backslash. Hope that helps.

您可以编写一个可以很好地完成此操作的函数，将其添加到您的 .vimrc 文件中：

function! s:surround()
    let word = expand("<cword>")
    let command = "%s/".word."/env[\'".word."\']/g"
    execute command
endfunction
map cx :call <SID>surround()<CR>

这将包围当前光标下出现的每个单词。

如果您想指定每个实例之前和之后发生的事情，您可以使用以下内容：

function! s:surround()
    let word = expand("<cword>")
    let before = input("what should go before? ")
    let after = input("what should go after? ")
    let command = "%s/".word."/".before.word.after."/g"
    execute command
endfunction
map cx :call <SID>surround()<CR>

如果您只想确认变量的每个实例，您可以使用以下内容：

function! s:surround()
    let word = expand("<cword>")
    let before = input("what should go before? ")
    let after = input("what should go after? ")
    let command = "%s/".word."/".before.word.after."/c"
    execute command
endfunction
map cx :call <SID>surround()<CR>

you could write a function that would do this pretty well, add this to your .vimrc file:

function! s:surround()
    let word = expand("<cword>")
    let command = "%s/".word."/env[\'".word."\']/g"
    execute command
endfunction
map cx :call <SID>surround()<CR>

This will surround every occurance of the word currently under the cursor.

If you wanted to specify what went before and after each instance you could use this:

function! s:surround()
    let word = expand("<cword>")
    let before = input("what should go before? ")
    let after = input("what should go after? ")
    let command = "%s/".word."/".before.word.after."/g"
    execute command
endfunction
map cx :call <SID>surround()<CR>

If you only want to confirm each instance of the variable you could use this:

function! s:surround()
    let word = expand("<cword>")
    let before = input("what should go before? ")
    let after = input("what should go after? ")
    let command = "%s/".word."/".before.word.after."/c"
    execute command
endfunction
map cx :call <SID>surround()<CR>

我想出了一种方法来完成我需要的事情。使用 q{0-9a-zA-Z"} 将击键记录到缓冲区中。将光标定位在变量名称的开头，然后 cw 并输入 < code>env['']。接下来将光标向后移动一个空格到最后一个引号，并使用 P 粘贴从 cw 命令填充的缓冲区。，为每个变量重复使用 @{0-9a-z".=*} 记录。
