smartparens not working with delete-selection-mode enabled

[LukeXuan]

Expected behavior

The expression in the region should be wrapped by brackets.

Actual behavior

The region gets deleted and/or strange unpaired brackets get inserted.

Also, when trying to view sp-local-pairs, an error is raised.

Steps to reproduce the problem

For any csharp/c/c++ file on my computer, it does not work. (However, smartparens is still working in elisp mode)

Backtraces if necessary (M-x toggle-debug-on-error)

For sp-local-pairs,

Debugger entered--Lisp error: (scan-error "Containing expression ends prematurely" 845 845)

Possible reason: something from rtag break it. Didn't confirm but it works now when I disable rtag mode. It's strange that rtag does never throw any error.

I have pushed a fix which might have been related to this issue. Can you check on the latest master build? (it will be on melpa in a couple hours or you can grab the git version manually)

[LukeXuan]

I'm using version 20181027.1542 from melpa and it's still broken when rtags enabled and working when rtags disabled. I might report the bug to rtags as well.

Did this ever get fixed? I am using smartparens with c/c++ mode and if I select a region and insert a parenthesis - it just wipes out entire region and leaves me with empty string. Seems to be only happening with c/c++ mode. I am not using rtags though but I do have lsp-mode enabled and delete-selection-mode enabled.

[Fuco1]

In C++ mode if I select a region and press (, [ or { it gets wrapped normally. Maybe there are some other "electric" settings from c++ mode interfering? I can't reproduce this issue.

[LukeXuan]

I no longer actively write code in C++ and I also changed my emacs packages drastically in last few years. All I can say is it's working for me right now.

Thank you for the feedback. I will close the issue now as it was already very old (sorry for being so slow :blush:). Hopefully it is fixed now.
