Can't disable auto-indent when pasting

[Blaisorblade]

SPC u p should paste without indent, but fails since at least an year.

Spc-u 4 p actually does paste four times without autoindention. Fun.

The relevant issue is #4219, but is mislabeled as question/forum/Python, which might be the reason it's open since a couple of years. There's even a proposed fix at #4219 (comment).

I managed to reproduce this problem in the develop branch (3e98896).

Description

On master branch, SPC u p fails with ad-Advice-evil-paste-after: Wrong type argument: number-or-marker-p, (4).

On develop branch, it will not fail, instead it will paste the same text 4 times as originally reported, but WITH indentation. This is easy to check on an C++ file, I basically copy some lines starting with "+" (I do this often when I'm copying from git diff buffers) and paste into a C++ buffer. With p, the indentation is performed and the pasted text is all deformed, but this is the expected bahaviour I guess. When using SPC u p, instead of the error, I get four copies of the yanked text, with the same deformation.

Reproduction guide 🪲

• Start Emacs
• Copy the following text

+for (auto item : container)
+{
+    std::cout << "items: " << item << std::endl;
+}

• Paste into a C++ buffer using SPC u p

Observed behaviour: 👀 💔
The text will be pasted 4 times, with indentation.

Expected behaviour: ❤️ 😄
The text should be pasted one time, without indentation. This is what I get when adding C++ to spacemacs-indent-sensitive-modes.

Analyzing the commands that are bound to p I get the following conclusions: on master branch, p is bound to evil-paste-after (which has specific help text stating how one could paste without indent by using SPC u); however on develop, the command has changed to spacemacs/evil-mc-paste-after, which does not say anything about universal argument, so I'm not sure if this new behaviour of pasting four times is a bug or not, at the very least I think it should be documented somehow.

Workaround

You can somehow work around this bug by modifying the variable spacemacs-indent-sensitive-modes on both develop and master. Here is an example to put into your dotspacemacs/user-config (replace with the modes you intent to paste without formatting)

  ;; I want to disable pasting with formatting on C/C++ buffers
  (add-to-list 'spacemacs-indent-sensitive-modes 'c-mode)
  (add-to-list 'spacemacs-indent-sensitive-modes 'c++-mode)

I'm also on branch develop (81a931f) and I have the same issue with both SPC u p and SPC u P.

Is this still relevant? I cannot reproduce this issue.

Thanks for testing this, your probably right.
