This makes it fairly robust even in\nthe face of invalid `Show` instances, that may not produce valid Haskell code.\n\n\n\n## Examples\n\n### Artificial\n\n```haskell\nHello Foo (\"(Bar\", Haha) (Baz (A { foo = C, bar = D, qux = (E,\"He)llo World!\",G,\n H,[A,B,c,d,e,Fghi]) } ) (B,C) [Baz A1 B2, (Baz A3 (B4)), (Baz A5 (B6)), (Baz\n (A7) B8)]) (Foo) (Bar) (Baz (A) (B))\n\n==\u003e\n\n\nHello Foo (\"(Bar\",Haha)\n (Baz (A {foo = C\n ,bar = D\n ,qux = (E,\"He)llo World!\",G,H,[A,B,c,d,e,Fghi])})\n (B,C)\n [Baz A1 B2,(Baz A3 (B4)),(Baz A5 (B6)),(Baz (A7) B8)])\n (Foo)\n (Bar)\n (Baz (A) (B))\n```\n\n### Inspired by a real AST\n\n```haskell\nSet (fromList [(Name \"A string with (parenthesis\",Ann (Entry (Quality 1 1)\n (Ann False) (Ann (Map [Ann (Bound (Ann (Id \"lorem\"))),Ann (Variable\n (Ann (Id \"ipsum\")))])))),(Name \"string\",Ann (Entry (Quality 1 1) (Ann\n True) (Ann (Internal (Ann (Reduce (Ann (Id \"dolor\")) (Ann (Id \"sit\")))))\n ))),(Name \"Another } here\",Ann (Entry (Quality 1 1) (Ann (Or [Ann (Not\n (Ann (Is (Ann Flagged) (Ann Type) (Ann (Multi [Ann (Literal (Ann One))\n ]))))),Ann (Is (Ann Flagged) (Ann Type) (Ann (Multi [Ann (Literal (Ann\n Three))]))),Ann (Is (Ann Flagged) (Ann Type) (Ann (Multi [Ann (Literal\n (Ann Two))])))])) (Ann (Internal (Ann (Concat (Ann (Id \"amet\"))))))))])\n\n==\u003e\n\nSet (fromList [(Name \"A string with (parenthesis\"\n ,Ann (Entry (Quality 1 1)\n (Ann False)\n (Ann (Map [Ann (Bound (Ann (Id \"lorem\")))\n ,Ann (Variable (Ann (Id \"ipsum\")))]))))\n ,(Name \"string\"\n ,Ann (Entry (Quality 1 1)\n (Ann True)\n (Ann (Internal (Ann (Reduce (Ann (Id \"dolor\"))\n (Ann (Id \"sit\"))))))))\n ,(Name \"Another } here\"\n ,Ann (Entry (Quality 1 1)\n (Ann (Or [Ann (Not (Ann (Is (Ann Flagged)\n (Ann Type)\n (Ann (Multi [Ann (Literal (Ann One))])))))\n ,Ann (Is (Ann Flagged)\n (Ann Type)\n (Ann (Multi [Ann (Literal (Ann Three))])))\n ,Ann (Is (Ann Flagged)\n (Ann Type)\n (Ann (Multi [Ann (Literal (Ann Two))])))]))\n (Ann (Internal (Ann (Concat (Ann (Id \"amet\"))))))))])\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fquchen%2Fshow-prettyprint","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fquchen%2Fshow-prettyprint","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fquchen%2Fshow-prettyprint/lists"}
