Some Questions/Thoughts

How do I get the name of the snippet at expand time? This would help with snippet reuse (e.g. some snippets are simple and differ only by name which is the name of a function/identifier/etc. that gets expanded in the snippet while everything else is the same), but the name field doesn't appear to exist on the snippet within a function node?

Is it possible to not specify jump index and have them filled-in automatically (based on the order that nodes appear)? At least half the time, this is the jump order I want and input manually anyway.

Snippet desc/docs preview win clobbers all consecutive newlines (reduces them to a single \n), although this appears to be the doing of cmp and/or vim.lsp functions, and there is a simple workaround (adding a space between any two \n).

Is it possible to nest nodes? Like insert nodes? So that I could delete an entire set of nodes just by pressing <BS> (because they would be selected/highlighted) before jumping into them? I don't think just using a snippetNode works, because IIRC luasnip skips the entire snippetNode when jumping and instead jumps to the 1st jumpable node within it. So I guess the only straightforward way to accomplish this is to use a choice node with one of the choices being an "empty" choice?

Hi :)

Mhmm, you can get the trigger of the snippet via parent.snippet.trigger..
But TBH, I think I'd define snippets like that via a function that takes the
keyword and generates all these similar snippets

local function make_similar_snippets(keyword)
    return s({trig=keyword}, {t"local function " .. keyword .. "(", i(1), t")"})
end
make_similar_snippets("foo")
make_similar_snippets("bar")
make_similar_snippets("foobar")

Unfortunately not possible right now, and I think implementing it would require either quite a bit of restructuring or some clever trick... If I get a good idea I'll consider it :)

Actually, it might be us doing this, could you check if this also occurs if you specify desc as a string[]?

Ah, I think we do have this in a roundabout way via this setting, but that works for parsed snippets only 😅
My idea for getting a similar behaviour are choiceNodes, where you can "delete" the set of nodes by switching to a different choice (ie. c(1, {sn(1, <many nodes>), i(1)}))
