[MVP][WIP] `less` like pager (#6984)
Run it as `explore`.
#### example
```nu
ls | explore
```
Configuration points in `config.nu` file.
```
# A 'explore' utility config
explore_config: {
highlight: { bg: 'yellow', fg: 'black' }
status_bar: { bg: '#C4C9C6', fg: '#1D1F21' }
command_bar: { fg: '#C4C9C6' }
split_line: '#404040'
cursor: true
# selected_column: 'blue'
# selected_row: { fg: 'yellow', bg: '#C1C2A3' }
# selected_cell: { fg: 'white', bg: '#777777' }
# line_shift: false,
# line_index: false,
# line_head_top: false,
# line_head_bottom: false,
}
```
You can start without a pipeline and type `explore` and it'll give you a
few tips.
If you type `:help` you an see the help screen with some information on
what tui keybindings are available.
From the `:help` screen you can now hit `i` and that puts you in
`cursor` aka `inspection` mode and you can move the cursor left right up
down and it you put it on an area such as `[table 5 rows]` and hit the
enter key, you'll see something like this, which shows all the `:`
commands. If you hit `esc` it will take you to the previous screen.
If you then type `:try` you'll get this type of window where you can
type in the top portion and see results in the bottom.
The `:nu` command is interesting because you can type pipelines like
`:nu ls | sort-by type size` or another pipeline of your choosing such
as `:nu sys` and that will show the table that looks like this, which
we're calling "table mode".
If you hit the `t` key it will now transpose the view to look like this.
In table mode or transposed table mode you can use the `i` key to
inspect any collapsed field like `{record 8 fields}`, `[table 16 rows]`,
`[list x]`, etc.
One of the original benefits was that when you're in a view that has a
lot of columns, `explore` gives you the ability to scroll left, right,
up, and down.
`explore` is also smart enough to know when you're in table mode versus
preview mode. If you do `open Cargo.toml | explore` you get this.
If you type `open --raw Cargo.toml | explore` you get this where you can
scroll left, right, up, down. This is called preview mode.
When you're in table mode, you can also type `:preview`. So, with `open
--raw Cargo.toml | explore`, if you type `:preview`, it will look like
this.
