Tags sometimes don't get highlighted until I force them to?

[haasn]

I'm not really sure how to debug this, or provide consistent or clear reproduction advice.

Sometimes I noticed that neotags simply doesn't highlight anything. Forcing it off and on again (:NeotagsToggle() twice) fixes it. As does switching to a different buffer and back (sometimes).

I use a lot of split buffers (:vsp etc.), maybe that has something to do with it?

I don't notice anything odd in :messages. I haven't had time to investigate this properly yet.

If you run :NeotagsVerbosity before you switch buffer you should be able to see what's going on 👍

After switching buffers, no proper highlighting:

Maybe you can tell what's going on? It seems like it just gets the wrong set of tags for that particular buffer. Maybe the "updating from cache" thing is the root of the issue here? Like, it either doesn't properly recognize that the cache is no longer valid since this is a different buffer, or it doesn't properly generate the cache to begin with?

[c0r73x]

Yeah, it looks like there is some issue with the cache. I will try to replicate it and check.

[haasn]

In case it helps, I usually switch buffers using the ctrlp extension, which is what I think has the highest rate of triggering this issue? Sometimes switching between different split windows fixes it, but this time it didn't. (Which is why I was able to produce the log)
