Postfix snippets not shown or shown too late

[pogopaule]

I created some postfix snippets.

I noticed that they always correctly expand, but they are either not shown in the completion list or are only shown if they fully written out. I have not yet been able to figure out when one or the other happens.

I don't have this problem with non-postfix snippets.

My config https://github.com/pogopaule/dotfiles/blob/master/nvim/lua/pogopaule/plugins/luasnip.lua

Let me look into this :)

[pogopaule]

I managed to narrow down the probable cause. A postfix snippet not appearing in the list only happens when my tmux or nvim_lsp source is active. So either the tmux/lsp source itself is the problem or that fact that the tmux/lsp source provides many many completion entries.

But what is not explained by the tmux source is the fact that I need to write out the full postfix snippet name to make it appear as a suggestion. This seems to be a problem independent of the "tmux source problem". This problem disappears if luasnip is my only source.

Example: The snippet's name is .log

With only .lo this happens

With .log

Now I disable all sources expect for luasnip and .l is sufficient to make the snippet appear.

Oh btw, are you using manual or auto-completion? It works for me with manual, but haven't tried auto

[pogopaule]

@L3MON4D3 What do you mean by auto-completion? I guess I use manual because I have to manually expand snippets and can't recall that I have configured something related to it.

And do you have a nvim_lsp source? Because the bug appears as soon as I activate it.

[L3MON4D3]

What do you mean by auto-completion?

Oh, just whether it's always on or if you have to press some key to invoke nvim-cmp.

Yup, I have the nvim_lsp-source :/ Are they only not listed with that one, or does any other source do it?

[pogopaule]

It is always on. The cmp list refreshes as I type.

I have these sources. If only luasnip, bufferand path are active --> no problem. If I activate tmux and/or nvim_lsp --> problem.

[L3MON4D3]

Oh does the order of the sources make a difference?

[pogopaule]

No, that does not matter. I tried a couple of variations.

But what I have noticed again is that the list of suggestions is populated with the postfix snippets for a blink of an eye and then get overridden with the suggestions from other sources.

[L3MON4D3]

Mhmm, I guess you'd have to take a look at cmp's issues and find similar ones, maybe see what kind of debugging-steps are taken (is there a quick way to check when the postfix-snippet is overridden?)
Maybe there is some heuristic in cmp to recognize specific items, and postfix-snippets trigger just that (starting with a dot..)

May have something to do with keyword_pattern?

For me, postsnip completion worked for vim, while could not work for cpp.

[L3MON4D3]

Maybe, but it sounds a bit more complicated then that (source and filetype affect postfix snippets showing up, while keyword pattern stays the same the entire time)

Hi, any workaround for this problem?
