🔰 A beginners guide to create custom cmdline

Ever wanted to know how noice creates the cmdline or wanted your own one?

No one? Guess it's just me 🥲.

Anyway, this post is a simple tutorial for creating a basic cmdline in neovim.

I just implemented a simple but really powerful user command suggested by romainl in lua, running asynchronously using vim.uv API.

In short, this is a command named Redir, which redirect ex command or shell commands stdin/sterr to neovim buffers. So you can view them in split window on the fly.

With Redir, you can do:

A good way to inspect your neovim.

" show all your messages in split, I love this one and make it default

Support for mouse emulation has now been implemented. See https://zmk.dev/docs/keymaps/behaviors/mouse-emulation

The instructions below are outdated.

Outdated instructions. Do ignore.

See this SO answer.

Disable large send offload in host on vEthernet (to avoid messing with non-virtual adapters). Disable large send offload in guest (including Windows Sandbox!) for all adapters (unable to predict adapter names and probably all of them are real).

Some random notes on trying (and failing) to get Proxmox as host with 5700G APU GPU PCI Passthrough to Ubuntu guest VM working:

Proxmox Assign Bind Mount To Unprivileged Container

In order for the LXC container to have full access the proxmox host directory, a subgid is set as owner of a host directory, and an ACL is used to ensure permissions.

Bind Mount dataset to LXC

Add the following line to /etc/pve/lxc/<CT_ID>.conf

mp0:/mount/point/on/host,mp=/mount/point/on/lxc

OR

pct set 100 -mp0 /mnt/bindmounts/shared,mp=/shared

free tier limits

The limits of the free tier say that you can create up to 4 instances.

x2 x86 instances (2core/1g)
x2 ampere instances (with 4core/24g spread between them)
200GB total boot volume space across all intances (minimum of 50G per instance)

GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.
