feat: Commands for cmdline

[vunhatchuong]

Add commands so people can lazy load with cmd

{
    'tamton-aquib/duck.nvim',
    cmd = "Duck",
    opts = {},
}

Or use it in keymap

vim.keymap.set('n', '<leader>dd', ":Duck hatch 🦆10<CR> , {}) -- A pretty fast duck

instead of

vim.keymap.set('n', '<leader>dd', function() require("duck").hatch("🦆", 10) end, {}) -- A pretty fast duck

Heyyo @vunhatchuong,

A relly cool addition ❤️ .

But could you move the file inside a folder called duck maybe? Else the command.lua will conflict with other module with the same name if the user has any. After moving and resolving the comments, I think I'll merge

Or it would be better to move the contents inside command.lua inside plugin/duck.lua.
Also is the complete() method needed? I think neovim will handle matches we might just need to return the table

[vunhatchuong]

Yeah that's what I initially want to do but I was afraid maybe it will break some user or that's not what you want.

To clarify, is this what you want?

.
├── lua
│   └── duck
│       ├── command.lua
│       ├── duck.lua
│       └── init.lua
├── .github/
├── CHANGELOG.md
├── LICENSE
├── README.md
└── plugin
    └── duck.lua

I export conf and put setup in init.lua.

This will be fine too. But if command.lua doesnt have much logic inside then i guess we could move it inside plugin/duck.lua itself.

So it becomes;

I think this is fine, what do you think?
