This was a prototype that never made it into a workable state. There is now lua-debug.nvim which can be used instead.
nvim-lua-debugger
is a Debug Adapter that allows debugging lua plugins written for Neovim.
It is the server component in the Debug Adapter Protocol.
To use the debugger you'll need a client implementing the Debug Adapter Protocol:
- initialization parts of the protocol
- setting breakpoints
- stopped event
- threads request handling
- stackTrace request handling
- scopes request handling
- variables request handling
- Requires Neovim HEAD/nightly
- nvim-lua-debugger is a plugin. Install it like any other Vim plugin.
- Call
:packadd nvim-lua-debugger
if you installnvim-lua-debugger
to'packpath'
.
Add a new adapter entry:
local dap = require('dap')
dap.adapters.neovim = function(callback)
local server = require('lua_debugger').launch()
callback({ type = 'server'; host = server.host; port = server.port; })
end
Add a new configuration entry:
local dap = require('dap')
dap.configurations.lua = {
{
type = 'neovim';
request = 'attach';
name = "Attach to running neovim instance";
},
}
Then edit a lua
file within Neovim and call :lua require'dap'.continue()
to start debugging.
