Sorting of output

[hinell]

There is a way to write sorting functions for nvim-cmp.

Checkout examples:

• https://github.com/hrsh7th/nvim-cmp/blob/main/lua/cmp/config/compare.lua
• https://github.com/lukas-reineke/cmp-under-comparator

Please, add info on caching. Thanks!

Hi @hinell ,

Thanks, would you be willing to open a PR?

I have tried to implement this with cmp.comparators, toke some code from #6 (comment)

And because it filters by filename so should have minimal impact to cmp overall.

  ---@param entry1 cmp.Entry
  ---@param entry2 cmp.Entry
  local function package_json_npm(entry1, entry2)
    local filename = vim.fn.expand('%:t')
    if filename == 'package.json' then
      local source1 = entry1.source.name
      local source2 = entry2.source.name

      -- make source npm has higher priority
      if source1 == 'npm' and source2 ~= 'npm' then
        return true
      end

      if source1 ~= 'npm' and source2 == 'npm' then
        return false
      end

      -- if both source are npm, sort by version
      if source1 == 'npm' and source2 == 'npm' then
        local label1 = entry1.completion_item.label
        local label2 = entry2.completion_item.label
        local major1, minor1, patch1 = string.match(label1, '(%d+)%.(%d+)%.(%d+)')
        local major2, minor2, patch2 = string.match(label2, '(%d+)%.(%d+)%.(%d+)')
        if major1 ~= major2 then
          return tonumber(major1) > tonumber(major2)
        end
        if minor1 ~= minor2 then
          return tonumber(minor1) > tonumber(minor2)
        end
        if patch1 ~= patch2 then
          return tonumber(patch1) > tonumber(patch2)
        end
      end
    end

    return false
  end
