Adapters for codecompanion

[matt-carty]

I'm really struggling to get codecompanion running with openrouter.ai. I have tried a couple of approaches, but I think the best way should be to define setupOpts.adapters. I am not good enough with lua to troubleshoot the missing } error that I'm getting. If anyone could point me towards a working example? My current config is

setupOpts.adapter = lib.generators.mkLuaInline ''
openrouter_claude = function()
          return require("codecompanion.adapters").extend("openai_compatible", {
            env = {
              url = "https://openrouter.ai/api",
              api_key = "OPENROUTER_API_KEY",
              chat_url = "/v1/chat/completions",
            },
            schema = {
              model = {
                default = "anthropic/claude-3.7-sonnet",
              },
            },
          })
'';

luaInline options should be lua expressions:

setupOpts.adapter.openrouter_claude = lib.generators.mkLuaInline ''
  function()
    return require("codecompanion.adapters").extend("openai_compatible", { env = { url = "https://openrouter.ai/api", api_key = "OPENROUTER_API_KEY", chat_url = "/v1/chat/completions", }, schema = { model = { default = "anthropic/claude-3.7-sonnet", }, }, }) 
 end
'';

(forgive the atrocious indentation, github mobile sucks)

Thank you for the reply. It makes sense to me but still doesn't work. (I did have adapter instead of adapters in the op, but that was a typo in github)

error: A definition for option `programs.nvf.settings.vim.assistant.codecompanion-nvim.setupOpts.adapters' is not of type `null or (luaInline)'. Definition values:
       - In `/nix/store/wbphg16k36mj3ba1py0gw88b8ly535sq-source/home/matt/common/global/nvf/default.nix':
           {
             openrouter_claude = {
               _type = "lua-inline";
               expr = ''
                  function()
           ...

This is the relevant config

assistant = {
          codecompanion-nvim = {
            enable = true;
            setupOpts.adapters.openrouter_claude = lib.generators.mkLuaInline ''
               function()
                 return require("codecompanion.adapters").extend("openai_compatible", { env = { url = "https://openrouter.ai/api", api_key = "OPENROUTER_API_KEY", chat_url = "/v1/chat/completions", }, schema = { model = { default = "anthropic/claude-4-sonnet", }, }, })
              end
            '';
            setupOpts.strategies.chat.adapter = "openrouter_claude";
          };
        };

I have tried putting everything as lua under setupOpts but couldn't get that to work.

codecompanion-nvim = {
            enable = true;
            setupOpts.adapters = lib.generators.mkLuaInline ''
              {
               openrouter_claude = function()
                 return require("codecompanion.adapters").extend("openai_compatible", { env = { url = "https://openrouter.ai/api", api_key = "OPENROUTER_API_KEY", chat_url = "/v1/chat/completions", }, schema = { model = { default = "anthropic/claude-4-sonnet", }, }, })
               end
              }
            '';
            setupOpts.strategies.chat.adapter = "openrouter_claude";
          };

sorry, adapters has kind of a weird type, this should work
