Beginner issue: unsure of the correct configuration

[Integralist]

👋🏻

I've used :VsnipOpen to create a new ~/.vsnip/... example, but I'm not sure of what to configure to get the list of available Snippets showing in my autocomplete menu when typing the 'trigger' name.

For example I have ~/.vsnip/go.json that contains:

{
  "Error Check": {
    "prefix": ["iferr"],
    "body": [
      "if err != nil {",
      "\treturn err"
      "}"
    ],
    "description": "err check and return."
  }
}

I'm also using cmp-vsnip like this in my plugin/cmp.lua:

local cmp = require("cmp")
cmp.setup({
  snippet = {
    expand = function(args)
        vim.fn["vsnip#anonymous"](args.body)
    end,
  },
  mapping = {
    ["<Up>"] = cmp.mapping.select_prev_item(),
    ["<Down>"] = cmp.mapping.select_next_item(),
    ["<Left>"] = cmp.mapping.select_prev_item(),
    ["<Right>"] = cmp.mapping.select_next_item(),
    ["<C-b>"] = cmp.mapping.scroll_docs(-4),
    ["<C-f>"] = cmp.mapping.scroll_docs(4),
    ["<C-Space>"] = cmp.mapping(cmp.mapping.complete(), { "i", "c" }),
    ["<C-e>"] = cmp.mapping.close(),
    ["<CR>"] = cmp.mapping.confirm({
      behavior = cmp.ConfirmBehavior.Insert,
      select = true,
    })
  },
  sources = {
    { name = "buffer" },
    { name = "nvim_lua" },
    { name = "nvim_lsp" },
    { name = "nvim_lsp_signature_help" },
    { name = "path" },
    { name = "vsnip" },
  },
})

Any guidance appreciated. ❤️
