QuickFix does not open after an error any more?

[symbolix]

Hi,

I am editing a simple C++ file. And before, the quickfix would pop-up in case of errors after running :Make. Now I need to run Copen after running :Make to view the errors and I am loosing the focus of my code buffer. Has anything changed? Is there a way to fix this? Thanks.

Nothing should have changed, no. Are you sure the error format is matching something?

I am sure nothing has changed on my side. Will investigate further. So the intended behaviour is that the quickfix window would open after a :Make command in case there are errors, and will stay silent in case the process is error free? Thanks.

Yes, where error means "errorformat matched" or "nonzero exit status".

I can confirm now that Quickfix List will not open automatically on a :Make call after the errors are generated (that used to be the case).

I have started a minimal VIM session with vim-dispatch being the only installed plugin and no extra settings being applied.

set runtimepath+=/Users/me/repos/github.com/tpope/vim-dispatch/

My VIM version is: MacVim 7.4 (1-1553) I have heard that the VIM people have recently released a significant change that influenced the Quickfix List and the LocationList behaviours? It is known as patch 1592 maybe this is changing things?

However (After further testing):
I can confirm that theQuickfix List functionality is working as intended when MacVim is directly running in a tmux session and started with the mvim -v command (Non-GUI).

I can confirm that theQuickfix List functionality is working as intended when VIM is started directly from a tmux session by running the /Applications/MacVim.app/Contents/MacOS/Vim command (once again Non-GUI).

It seems like only the GUI versions is affected. In my case, launching MacVim from a tmux session, but as GUI application, with the mvim command. Once :Make is invoked, I can see the extra tmux buffer flashing, the process is done, the errors are there, but I need to run :Copen to bring up the Quickfix List.

I have found out that when the GUI MacVim is started from a tmux session. The Quickfix List is NOT working as intended (it used to work just fine before). However, when started from a plain iterm2 tab, the Quickfix List is working as intended. Has something changed in the tmux adapter?

Ok, apologies for the messy reporting, I managed to track down the issue. So here are my findings:

1. Inside tmux (no tmux panes) >> mvim (GUI MacVim) >> Quickfix List works
2. Inside tmux (one extra tmux pane) >> mvim (GUI MacVim) >> Quickfix List NOT working
3. Inside tmux (no tmux panes) >> mvim -v (Non-GUI MacVim) >> Quickfix List works
4. Inside tmux (one extra tmux pane) >> mvim -v (Non-GUI MacVim) >> Quickfix List works
5. Inside iterm2 (no iterm2 splits) >> mvim (GUI MacVim) >> Quickfix List works
6. Inside iterm2 (with an iterm2 split) >> mvim (GUI MacVim) >> Quickfix List NOT working
7. Inside iterm2 (no iterm2 splits) >> mvim -v (Non-GUI MacVim) >> Quickfix List works
8. Inside iterm2 (with an iterm2 split) >> mvim -v (Non-GUI MacVim) >> Quickfix List works

So it seems like the GUI Vim is hit in cases where there are extra iTerm2 splits or tmux splits. The NON-GUI Vim works in all cases.

This is getting really confusing. I have restarted iTerm2 and tmux. Now Quickfix List works as intended in all of the cases with the :Make command. I cannot reproduce the issues described above any more. Maybe it has something to do with the number of open splits and tabs etc. I tried opening up quite a lot of iterm2 tabs and quite a lot of tmux windows with panes, every time the Quickfix List worked with the :Make command on both GUI and Non-GUI vim sessions.

One thing I can confirm though is, If I run MacVim (GUI) by running the mvim command in an iterm2 split, I get a new tab, called Shell and the Quickfix List will not pup-up after the :Make command and I can see the text !make (iterm/?) in the status. But when I run :Make for the second time. The Quickfix List pops-up.

Sorry about the confusion, there is certainly something fishy going on in there, but it is hard to reproduce.

I can confirm that last one. Not surprised that there are issues with iTerm
splits.

Thanks. I shall close this now. I will re-open or start a new one if I manage to reproduce the problem. One last thing to mention though, while I was stress-testing vim-dispatch I got a function error with an <SID> ... in there, and then an error about not being able to write a tmp file (all messages related to vim-dispatch). Unfortunately I lost that session, and I do not have further evidence. But I will post them here if I come across this issue again.
