Utility functions you can use in your code.

Personally, I have the code below at the top of my `init.lua`:

>lua
    _G.dd = function(...)
      Snacks.debug.inspect(...)
    end
    _G.bt = function()
      Snacks.debug.backtrace()
    end
    if vim.fn.has("nvim-0.11") == 1 then
      vim._print = function(_, ...)
        dd(...)
      end
    else
      vim.print = dd
    end
<

What this does:

- Add a global `dd(...)` you can use anywhere to quickly show a
    notification with a pretty printed dump of the object(s)
    with lua treesitter highlighting
- Add a global `bt()` to show a notification with a pretty
    backtrace.
- Override Neovim’s `vim.print`, which is also used by `:= {something = 123}`

`Snacks.debug()`                                              *Snacks.debug()*

>lua
    ---@type fun(...)
    Snacks.debug()
<


`Snacks.debug.backtrace()`                          *Snacks.debug.backtrace()*

Show a notification with a pretty backtrace

>lua
    ---@param msg? string|string[]
    ---@param opts? snacks.notify.Opts
    Snacks.debug.backtrace(msg, opts)
<


`Snacks.debug.cmd()`                                      *Snacks.debug.cmd()*

>lua
    ---@param opts snacks.debug.cmd
    Snacks.debug.cmd(opts)
<


`Snacks.debug.inspect()`                              *Snacks.debug.inspect()*

Show a notification with a pretty printed dump of the object(s) with lua
treesitter highlighting and the location of the caller

>lua
    Snacks.debug.inspect(...)
<


`Snacks.debug.log()`                                      *Snacks.debug.log()*

Log a message to the file `./debug.log`. - a timestamp will be added to every
message. - accepts multiple arguments and pretty prints them. - if the argument
is not a string, it will be printed using `vim.inspect`. - if the message is
smaller than 120 characters, it will be printed on a single line.

>lua
    Snacks.debug.log("Hello", { foo = "bar" }, 42)
    -- 2024-11-08 08:56:52 Hello { foo = "bar" } 42
<

>lua
    Snacks.debug.log(...)
<


`Snacks.debug.metrics()`                              *Snacks.debug.metrics()*

>lua
    Snacks.debug.metrics()
<


`Snacks.debug.profile()`                              *Snacks.debug.profile()*

Very simple function to profile a lua function. **flush**: set to `true` to use
`jit.flush` in every iteration. **count**: defaults to 100

>lua
    ---@param fn fun()
    ---@param opts? {count?: number, flush?: boolean, title?: string}
    Snacks.debug.profile(fn, opts)
<


`Snacks.debug.run()`                                      *Snacks.debug.run()*

Run the current buffer or a range of lines. Shows the output of `print` inlined
with the code. Any error will be shown as a diagnostic.

>lua
    ---@param opts? {name?:string, buf?:number, print?:boolean}
    Snacks.debug.run(opts)
<


`Snacks.debug.size()`                                    *Snacks.debug.size()*

>lua
    Snacks.debug.size(bytes)
<


`Snacks.debug.stats()`                                  *Snacks.debug.stats()*

>lua
    ---@param opts? {min?: number, show?:boolean}
    ---@return {summary:table<string, snacks.debug.Stat>, trace:snacks.debug.Stat[], traces:snacks.debug.Trace[]}
    Snacks.debug.stats(opts)
<


`Snacks.debug.trace()`                                  *Snacks.debug.trace()*
