 Prettier APIs and tools for deno
 ## Use as a CLI
 To formats the source files, run:
 ```bash
 deno --allow-read --allow-write https://deno.land/std/prettier/main.ts
 ```
 You can format only specific files by passing the arguments.
 ```bash
 deno --allow-read --allow-write https://deno.land/std/prettier/main.ts path/to/script.ts
 ```
 You can format files on specific directory by passing the directory's path.
 ```bash
 deno --allow-read --allow-write https://deno.land/std/prettier/main.ts path/to/script.ts
 ```
 You can format the input plain text stream. default parse it as typescript code.
 ```bash
 cat path/to/script.ts | deno https://deno.land/std/prettier/main.ts
 cat path/to/script.js | deno https://deno.land/std/prettier/main.ts --stdin-parser=babel
 cat path/to/config.json | deno https://deno.land/std/prettier/main.ts --stdin-parser=json
 cat path/to/README.md | deno https://deno.land/std/prettier/main.ts --stdin-parser=markdown
 ```
 ## Use API
 You can use APIs of prettier as the following:
 ```ts
 import {
  prettier,
  prettierPlugins
 } from "https://deno.land/std/prettier/prettier.ts";
 prettier.format("const x = 1", {
  parser: "babel",
  plugins: prettierPlugins
 }); // => "const x = 1;"

  --jsx-single-quote                    Use single quotes instead of double
                                        quotes in JSX.
  --jsx-bracket-same-line               Put the > of a multi-line JSX element at
                                        the end of the last line instead of
                                        being alone on the next line (does not
                                        apply to self closing elements).
  --trailing-comma <none|es5|all>       Print trailing commas wherever possible
                                        when multi-line. Defaults to none.
  --no-bracket-spacing                  Do not print spaces between brackets.
  --arrow-parens <avoid|always>         Include parentheses around a sole arrow
                                        function parameter. Defaults to avoid.
  --end-of-line <auto|lf|crlf|cr>       Which end of line characters to apply.
                                        Defaults to auto.
 Markdown Styling Options:
  --prose-wrap <always|never|preserve>  How to wrap prose. Defaults to preserve.
 Example:
  deno run prettier/main.ts --write script1.ts script2.js
                                        Formats the files

                                        Checks if the files are formatted
  deno run prettier/main.ts --write
                                        Formats the all files in the repository
  deno run prettier/main.ts script1.ts
                                        Print the formatted code to stdout
  cat script1.ts | deno run prettier/main.ts
                                        Read the typescript code from stdin and
                                        output formatted code to stdout.
  cat config.json | deno run prettier/main.ts --stdin-parser=json
                                        Read the JSON string from stdin and
                                        output formatted code to stdout.
