Neogen sync/update [feature request] about neogen

[danymat]

what about just re-doing Neogen command and it does it automatically ? So no need of a sync function?

This will not work because it'll override the annotation

[danymat]

Hmm it seems difficult to implement, as how we could retrieve easily the annotation and see if it has been changed

Do you have any ideas ? Maybe with some regex

[smackesey]

Really what's needed is a treesitter grammar for the annotations themselves-- so it would be a feature that relatively few languages support, but IMO definitely worth it for popular ones.

I could implement this for Python google-style docstrings.

You mean creating a grammar for annotations ? That could work indeed, but as of right now, we don't have any.

you could retrieve the old annotation, create the new one, compare the "fields", see where values are set, set the im the new annotation -> profit :)

the problem is: how do you know something is the old annotation ? That's why having a parser for annotations could be a huge benefit, but I don't think it's something easily feasible

you just get the comment about the function and check if it's kinda like the annotations format e.g. ---in lua

Even though, this check is not sufficient, take a look:

--- this is not meant to be an annotation
function test()
end

If we allow this type of behavior, this will mean that everything on top of the function, that has --- will be deleted and replaced with new annotation. I don't think this is a good idea, because the user should be expected to clearly know the result of the command before typing it out.

hmmm

One way to handle this, would be to keep the Information about created annotation (with marks)
But that would mean that exiting neovim will lose the informations

[sputnick1124]

For reference, it seems like this is possible with bare luasnip (at least for the active session, exiting neovim still poses a problem). LuaSnip's README shows a GIF of this working, but the source code for the demo even admits that it is ugly and fragile. I'm not sure what the existing neogen+luasnip integration looks like, but I'm wondering if some combination of setting history = true in luasnip and using restoreNode would get close?
