Hmmm I should really put more notes from 'README.md` in here (or just break it up better) so I have a concise view of sections and not just random meanderings
Completion
Well, the completion thing is REALLY annoying as sometimes it breaks and I have no idea why. Taking some notes off claude to try and debug it next time it happens
# Main Neovim log (all Lua errors, warnings)
~/.local/state/nvim/log
# Or programmatically:
:lua vim.print(vim.fn.stdpath('log'))
# View in real-time:
tail -f ~/.local/state/nvim/log
Or for verbosity
:messages # In-session messages (cleared on restart)
:messages clear # Clear message history
:set verbose=9 # Enable verbose logging (0-15, higher = more)
:set verbosefile=/tmp/nvim-verbose.log # Log to file
Or more logs
# In terminal:
tail -f ~/.local/state/nvim/log
Or in Neovim:
:edit ~/.local/state/nvim/log
Or
:Lazy reload nvim-cmp
Or
- Try reloading plugins
:Lazy reload nvim-cmp
:Lazy reload noice.nvim
- Disable noice temporarily
:lua package.loaded['noice'] = nil
:lua vim.cmd('messages clear')
Then test :e
- Check cmp status
:lua vim.print(require('cmp').visible()) # Is menu showing?
:lua vim.print(require('cmp').get_config()) # Config loaded?
- Nuclear option - reload everything
:Lazy reload nvim-cmp
:source $MYVIMRC
Enable Persistent Verbose Logging
Add this to your init.lua for debugging:
-- Only enable when debugging:
-- vim.opt.verbose = 9
-- vim.opt.verbosefile = vim.fn.stdpath('cache') .. '/nvim-verbose.log'
Then you can check that log file whenever things break.
Want me to create a custom debug command that runs all these checks and outputs a report for you?
Print buffers
So tried a super simple script to print windows and associated buffers as below (can save in scratchpads)
local wins = vim.api.nvim_list_wins()
local current_buf = vim.api.nvim_get_current_buf()
for winindex, winid in ipairs(wins) do
print('processing window #' .. winindex .. ', ID: ' .. winid)
local bufid = vim.api.nvim_win_get_buf(winid)
print('window buffer id is ' .. bufid)
local bufname = vim.api.nvim_buf_get_name(bufid)
print('buffer name is ' .. bufname)
if current_buf == bufid then
print 'is active buffer!'
end
end
and then call with :luafile scratchpads/...
Well i've moved scratchpads to a commited dir to git now (except for the brave preferences files). And the updated scripts lives in ./scratchpads/print_bufs.lua
Previous boot log
One i ALWAYS forget is to view last boot logs, its journalctl, NOT dmesg.
Substitute
Well it turns out mini surround replaces the s key, which would be nice to see the menu?
But claude made a good suggestion just using c for change. cl changes (left) which is the same thing as s...
Stylua
While i remember, stylua complaining was nothing to do with conform. It was installed by LSP (for some reason I had added it to list of LSP configurations 🤦♂️)
So if i see that one again can just remember to do :LspUninstall stylua
Tmux language server
Keep getting bizarre errors from tmux-language-server not sure how to fix on textDocument/didChange but honestly not worth my time to dive into... maybe in the future (although lets be honest not going to happen...)

Lazy dynamic inspection
Yet another fantastically documented feature of lazy.vim
To inspect plugins AFTER loading can use this
pls = require('lazy.core.config')
print(pls.plugins)
There is a throwaway comment here on their docs but it doesn't exactly do much explanation... 🤦♂️
So with claudes help I also managed to track custom user events to find when nvim DAP is loaded (as its lazy?)
local user_event_path = vim.fn.getcwd() .. "/user_events.log"
local f = io.open(user_event_path, "a")
vim.api.nvim_create_autocmd("User", {
callback = function(args)
if f ~= nil then
f:write("got a user event!\n" .. vim.inspect(args) .. "\n")
end
end,
})
And with that, found what i was after when nvim dap is loaded (on pressing f7 to bring up the UI)
{
buf = 3,
data = "nvim-dap-ui",
event = "User",
file = "LazyLoad",
id = 150,
match = "LazyLoad"
}
Debugging
Well I'm FINALLY getting around to attempting to configure debugging, given the need is here.
Seems that kickstar has improved the debugging since I last checked. The only thing remaining to install for JS to work is :Mason install js-debug-adapter
Had some weird stuff with 127.0.0.1 not working as the js debug adapter was expecting ipv6? but managed to resolve that.
And the args for ts-node (or i guess I should use tsx) need configuring.
But in general these might change, so i wrote a script that can be executed in luapad
function printer_util(entry)
local function inner(key, value, indent)
if type(value) == 'table' then
print(string.rep(' ', indent) .. tostring(key))
for k, v in pairs(value) do
inner(k, v, indent + 1)
end
else
print(string.rep(' ', indent) .. tostring(key) .. ': ' .. tostring(value))
end
end
inner('_', entry, 0)
end
printer_util("hi")
dap = require('dap')
printer_util(dap.configurations)
ok and FINALLY, i have per project no env variable...
... (see above)
printer_util(dap.configurations)
=> "_: hi"
"_"
" go"
" 1"
" type: delve"
" program: ${workspaceFolder}"
" request: launch"
