Configuration examples are in Lua. See:help lua-commands if your Neovim setup so far uses ainit.vim file.

Installcodelldb:

• Download theVS Code extension.
• Unpack it..vsix is a zip file and you can useunzip to extract the contents.

codelldb uses TCP for the DAP communication - that requires using theserver type for the adapter definition. See:help dap-adapter.

Up to including version 1.6.10 you could launchcodelldb and it printed out a port it was listening to:

$ codelldbListening on port 13123

Starting with version 1.7.0 it is necessary to specify the port:

$ codelldb --port 13000

To have nvim-dap connect to it, you can define an adapter like this:

localdap=require('dap')dap.adapters.codelldb= {type='server',host='127.0.0.1',port=13000-- 💀 Use the port printed out or specified with `--port`}

With this adapter definition you'll have to launchcodelldb manually in aterminal first whenever you want to debug your application.

If you want nvim-dap to automatically spawn the debug adapter beforeconnecting, you can use the following for version 1.7.0 and later:

dap.adapters.codelldb= {type='server',port="${port}",executable= {-- CHANGE THIS to your path!command='/absolute/path/to/codelldb/extension/adapter/codelldb',args= {"--port","${port}"},-- On windows you may have to uncomment this:-- detached = false,  }}

localdap=require('dap')dap.adapters.codelldb=function(on_adapter)localstdout=vim.loop.new_pipe(false)localstderr=vim.loop.new_pipe(false)-- CHANGE THIS!localcmd='/absolute/path/to/codelldb/extension/adapter/codelldb'localhandle,pid_or_errlocalopts= {stdio= {nil,stdout,stderr},detached=true,  }handle,pid_or_err=vim.loop.spawn(cmd,opts,function(code)stdout:close()stderr:close()handle:close()ifcode~=0thenprint("codelldb exited with code",code)endend)assert(handle,"Error running codelldb:"..tostring(pid_or_err))stdout:read_start(function(err,chunk)assert(noterr,err)ifchunkthenlocalport=chunk:match('Listening on port (%d+)')ifportthenvim.schedule(function()on_adapter({type='server',host='127.0.0.1',port=port          })end)elsevim.schedule(function()require("dap.repl").append(chunk)end)endendend)stderr:read_start(function(err,chunk)assert(noterr,err)ifchunkthenvim.schedule(function()require("dap.repl").append(chunk)end)endend)end

• Rust-Tools only If you are using this adapter for debugging Rust and are using therust-tools extension, there is a helper function defined for setting upCodeLLDB.This helper function works the same way as the function defined in the point above.Set it up as definedhere.

Have a look at thisissue for more information onCodeLLDB definition.

Thecodelldb manual contains a full reference for all options supported by the debug adapter.

A common configuration example:

localdap=require('dap')dap.configurations.cpp= {  {name="Launch file",type="codelldb",request="launch",program=function()returnvim.fn.input('Path to executable:',vim.fn.getcwd()..'/','file')end,cwd='${workspaceFolder}',stopOnEntry=false,  },}

If you want to use this debug adapter for other languages, you can re-use the configurations:

dap.configurations.c=dap.configurations.cppdap.configurations.rust=dap.configurations.cpp

The executables that you want to debug need to be compiled with debug symbols.
