### Pretty Printer Output Variations

Source: https://github.com/haskell-prettyprinter/prettyprinter/blob/master/prettyprinter/README.md

Illustrates the output of the pretty printer for different format widths. The first example shows the output for a wide format, and the second shows the output for a narrow format.

```haskell
-- Output for wide enough formats:
example :: Int -> Bool -> Char -> IO ()

-- Output for narrow formats:
example :: Int
        -> Bool
        -> Char
        -> IO ()

```

### ansi-wl-pprint to prettyprinter Conversion Diagram

Source: https://github.com/haskell-prettyprinter/prettyprinter/blob/master/prettyprinter-convert-ansi-wl-pprint/README.md

Illustrates the conversion flow between ansi-wl-pprint documents and prettyprinter's AnsiStyle documents using fromAnsiWlPprint and toAnsiWlPprint functions.

```text
╭────────────────────╮    fromAnsiWlPprint    ╭────────────────────╮
│        Doc         ├───────────────────────▷│   Doc AnsiStyle    │
│  (ansi-wl-pprint)  │◁───────────────────────┤  (prettyprinter)   │
╰────────────────────╯     toAnsiWlPprint     ╰────────────────────╯
```

### Pretty Printing a Function Signature

Source: https://github.com/haskell-prettyprinter/prettyprinter/blob/master/prettyprinter/README.md

This snippet demonstrates how to pretty print a function signature using align, sep, and zipWith. It shows how the output adapts to different format widths.

```haskell
let prettyType = align . sep . zipWith (<+>) ("::" : repeat "->")
    prettySig name ty = pretty name <+> prettyType ty
in  prettySig "example" ["Int", "Bool", "Char", "IO ()"]

```

### Old encloseSep behavior vs. new

Source: https://github.com/haskell-prettyprinter/prettyprinter/blob/master/prettyprinter/CHANGELOG.md

Illustrates the change in `encloseSep` behavior where the old version included an `align` wrapper, while the new version does not.

```haskell
encloseSep_old … = align (encloseSep_new …)
```

### Prettyprinting a Function Signature

Source: https://github.com/haskell-prettyprinter/prettyprinter/blob/master/README.md

This snippet demonstrates how to prettyprint a function signature using alignment and separators. It shows the output for both wide and narrow formats.

```haskell
let prettyType = align . sep . zipWith (<+>) (":" : repeat "->")
    prettySig name ty = pretty name <+> prettyType ty
in  prettySig "example" ["Int", "Bool", "Char", "IO ()" ]
```

```haskell
-- Output for wide enough formats:
example :: Int -> Bool -> Char -> IO ()

-- Output for narrow formats:
example :: Int
        -> Bool
        -> Char
        -> IO ()
```
