如何在 VimScript 中获得视觉上选择的文本 [英] How to get visually selected text in VimScript

问题描述

我可以使用 getpos() 获取光标位置，但我想在一行内检索所选文本 内，即 '<,'>.这是怎么做的?

I'm able to get the cursor position with getpos(), but I want to retrieve the selected text within a line, that is '<,'>. How's this done?

更新

我想我删掉了我解释说我想从 Vim 脚本中获取此文本的部分...

I think I edited out the part where I explained that I want to get this text from a Vim script...

推荐答案

我不完全确定这里的上下文，因为 getpos() 确实可以接受标记(例如 '< 和 '>) 作为参数.

I'm not totally sure about the context here, because getpos() can indeed accept marks (like '< and '>) as arguments.

然而，为了了解您可能需要的内容，还有 v，它类似于 '<，只是它总是更新(即当用户仍处于可视模式).这可以与 . 结合使用，当前光标位置将代表视觉选择的结束.

However, to take a stab at what you might be asking for, there's also v, which is like '< except it's always updated (i.e. while the user is still in visual mode). This can be used in combination with ., the current cursor position, which will then represent the end of the visual selection.

我在 :help line() 中找到了这些；包括 line() 和 getpos() 在内的几个函数具有相同的可能参数集.

I found these in :help line(); several functions including line() and getpos() have the same set of possible arguments.

我猜您可能只是在问如何在两个任意标记之间获取文本，而不是逐行...(即这与视觉模式无关).我认为实际上没有办法.是的，这似乎是一个非常明显的遗漏.您应该可以通过使用 getpos() 查找标记来伪造它，使用 getline() 获取所有行，然后根据列位置(个案工作取决于它是否是多行).抱歉，这不是一个真正的答案，但至少您可以将其包装在一个函数中并忘记它.

I guess you're probably simply asking how to get the text between two arbitrary marks, not going line-by-line... (i.e. this doesn't specifically pertain to visual mode). I don't think there actually is a way. Yes, this seems like a pretty glaring omission. You should be able to fake it by finding the marks with getpos(), getting all the lines with getline(), then chopping off on the first and last according to the column position (with casework depending on whether or not it's multi-line). Sorry it's not a real answer, but at least you can wrap it up in a function and forget about it.
