JS Beautifier --------------- Written by Einar Lielmanis, <einar@beautifier.io> https://beautifier.io/ Originally converted to javascript by Vital, <vital76@gmail.com> "End braces on own line" added by Chris J. Shull, <chrisjshull@gmail.com> Parsing improvements for brace-less statements by Liam Newman <bitwiseman@beautifier.io> Usage: js_beautify(js_source_text); js_beautify(js_source_text, options); The options are: indent_size (default 4) - indentation size, indent_char (default space) - character to indent with, preserve_newlines (default true) - whether existing line breaks should be preserved, max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk, jslint_happy (default false) - if true, then jslint-stricter mode is enforced. jslint_happy !jslint_happy --------------------------------- function () function() switch () { switch() { case 1: case 1: break; break; } } space_after_anon_function (default false) - should the space before an anonymous function's parens be added, "function()" vs "function ()", NOTE: This option is overriden by jslint_happy (i.e. if jslint_happy is true, space_after_anon_function is true by design) brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "none" | any of the former + ",preserve-inline" put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are. preserve-inline will try to preserve inline blocks of curly braces space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)", unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65" wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters. NOTE: This is not a hard limit. Lines will continue until a point where a newline would be preserved if it were present. end_with_newline (default false) - end output with a newline e.g js_beautify(js_source_text, { 'indent_size': 1, 'indent_char': '\t' }); */ (function() { /* GENERATED_BUILD_OUTPUT */ var legacy_beautify_js; /******/ (function() { // webpackBootstrap /******/ "use strict"; /******/ var __webpack_modules__ = ([ /* 0 */ /***/ (function(module, __unused_webpack_exports, __webpack_require__) { /*jshint node:true */ /* The MIT License (MIT) Copyright (c) 2007-2018 Einar Lielmanis, Liam Newman, and contributors.

JS Beautifier --------------- Written by Einar Lielmanis, <einar@beautifier.io> https://beautifier.io/ Originally converted to javascript by Vital, <vital76@gmail.com> "End braces on own line" added by Chris J. Shull, <chrisjshull@gmail.com> Parsing improvements for brace-less statements by Liam Newman <bitwiseman@beautifier.io> Usage: js_beautify(js_source_text); js_beautify(js_source_text, options); The options are: indent_size (default 4) - indentation size, indent_char (default space) - character to indent with, preserve_newlines (default true) - whether existing line breaks should be preserved, max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk, jslint_happy (default false) - if true, then jslint-stricter mode is enforced. jslint_happy !jslint_happy --------------------------------- function () function() switch () { switch() { case 1: case 1: break; break; } } space_after_anon_function (default false) - should the space before an anonymous function's parens be added, "function()" vs "function ()", NOTE: This option is overriden by jslint_happy (i.e. if jslint_happy is true, space_after_anon_function is true by design) brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "none" | any of the former + ",preserve-inline" put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are. preserve-inline will try to preserve inline blocks of curly braces space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)", unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65" wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters. NOTE: This is not a hard limit. Lines will continue until a point where a newline would be preserved if it were present. end_with_newline (default false) - end output with a newline e.g js_beautify(js_source_text, { 'indent_size': 1, 'indent_char': '\t' }); */ (function() { /* GENERATED_BUILD_OUTPUT */ var legacy_beautify_js; /******/ (function() { // webpackBootstrap /******/ "use strict"; /******/ var __webpack_modules__ = ([ /* 0 */ /***/ (function(module, __unused_webpack_exports, __webpack_require__) { /*jshint node:true */ /* The MIT License (MIT) Copyright (c) 2007-2018 Einar Lielmanis, Liam Newman, and contributors.

JS Beautifier --------------- Written by Einar Lielmanis, <einar@beautifier.io> https://beautifier.io/ Originally converted to javascript by Vital, <vital76@gmail.com> "End braces on own line" added by Chris J. Shull, <chrisjshull@gmail.com> Parsing improvements for brace-less statements by Liam Newman <bitwiseman@beautifier.io> Usage: js_beautify(js_source_text); js_beautify(js_source_text, options); The options are: indent_size (default 4) - indentation size, indent_char (default space) - character to indent with, preserve_newlines (default true) - whether existing line breaks should be preserved, max_preserve_newlines (default unlimited) - maximum number of line breaks to be preserved in one chunk, jslint_happy (default false) - if true, then jslint-stricter mode is enforced. jslint_happy !jslint_happy --------------------------------- function () function() switch () { switch() { case 1: case 1: break; break; } } space_after_anon_function (default false) - should the space before an anonymous function's parens be added, "function()" vs "function ()", NOTE: This option is overriden by jslint_happy (i.e. if jslint_happy is true, space_after_anon_function is true by design) brace_style (default "collapse") - "collapse" | "expand" | "end-expand" | "none" | any of the former + ",preserve-inline" put braces on the same line as control statements (default), or put braces on own line (Allman / ANSI style), or just put end braces on own line, or attempt to keep them where they are. preserve-inline will try to preserve inline blocks of curly braces space_before_conditional (default true) - should the space before conditional statement be added, "if(true)" vs "if (true)", unescape_strings (default false) - should printable characters in strings encoded in \xNN notation be unescaped, "example" vs "\x65\x78\x61\x6d\x70\x6c\x65" wrap_line_length (default unlimited) - lines should wrap at next opportunity after this number of characters. NOTE: This is not a hard limit. Lines will continue until a point where a newline would be preserved if it were present. end_with_newline (default false) - end output with a newline e.g js_beautify(js_source_text, { 'indent_size': 1, 'indent_char': '\t' }); */ (function() { /* GENERATED_BUILD_OUTPUT */ var legacy_beautify_js; /******/ (function() { // webpackBootstrap /******/ "use strict"; /******/ var __webpack_modules__ = ([ /* 0 */ /***/ (function(module, __unused_webpack_exports, __webpack_require__) { /*jshint node:true */ /* The MIT License (MIT) Copyright (c) 2007-2018 Einar Lielmanis, Liam Newman, and contributors.
