Can I use snippet just to trigger vim command ?

[aca]

Hi,

There's command something like this :lua vim.cmd.GoIfErr().

Which insert snippet

if err != nil {
    return err
}

It's provided by another plugin (which executes shell command).

Instead of executing command in vim or inoremap, I want to use luasnip to trigger the command.

I tried this but doesn't work.

ls.add_snippets("go", {
    s({ trig = "rerr", dscr = "iferr" }, {
        f(function()
            vim.cmd.GoIfErr()
        end, {}),
    }),
})

Wish I could get some help. Thanks.

TBH, I don't think this is a good idea, we assume that the buffer is not modified while inserting a snippet.
It might work if the functionNode returns a "" (ie the snippet does not insert any text), but please don't count on it.

I think it's better to use an iabbrev for this use case.

Ended up creating plugin with nvim-cmp, thanks for the reply.
