Sometimes running neomake can change which buffer is showing in your window

[benekastah]

Particularly when I do :lopen, sometimes a subsequent JobActivity handler call will switch my file buffer into the loclist buffer. It has to do with the code in the handler that briefly switches back to the original window/buffer you were on when you invoked neomake to process the task.

One potential solution is to only perform this work if the user is in the same window/buffer as they were when they invoked neomake. If they leave that window/buffer, defer the work until they return. Otherwise, we'll just have to make the current switching mechanism more robust.

Just adding a note here, this problem will be much more easily solved when some of the suggestions in neovim/neovim#901 get implemented, particularly bufputlines and bufgetlines

[benekastah]

Yes, having functions that operate on a buffer without having to navigate to it would be fantastic. The hacks you have to do to get some of this stuff to work are pretty gross.

Just wanted to chime in this happens to me regularly. Must be my habit of saving a file and switching to another buffer quickly.

I'm hoping there's a fix for this prior to neovim/neovim#901, since that could take awhile.

Yes, I get this a lot as well. I save, switch to another split window and the previous buffer changes :(

I have a partial fix for this. It's got a couple of issues of its own I'm trying to work out. Hopefully it will be complete soon.

@benekastah++ 100 internet points if you fix this.

Ok, this should be fixed now. I got rid of the fancy window/buffer switching code that I had before, which means that if you want to see the result of :Neomake, you need to be in the buffer you started it from. You can leave the buffer; the output of the job(s) will be processed when you come back. It should be noted this restriction doesn't apply to :Neomake! (note the exclamation point). If you are in a quickfix window, :Neomake will try to process the output for the last window you were in (which does actually require a window switch, but it is much simpler than the last version).

Seems to work great. Thanks @benekastah
