""" // Using default options let minified = try HTMLMinifier.minify(html) print(minified) ``` ### Custom Options ```swift import HTMLMinifier let options = HTMLMinifierOptions( removeComments: true, collapseWhitespace: true, removeAttributeQuotes: true, useShortDoctype: true ) let minifier = try HTMLMinifier() let result = try minifier.minify(html, options: options) ``` ### Static Methods ```swift // Using default options let result1 = try HTMLMinifier.minify(html) // Using custom options let result2 = try HTMLMinifier.minify(html, options: options) ``` ## Available Options All options are disabled by default unless specified otherwise. ### Core Options - `caseSensitive` (default: `false`): Treat attributes in case sensitive manner (useful for custom HTML tags) - `html5` (default: `true`): Parse input according to HTML5 specifications - `includeAutoGeneratedTags` (default: `true`): Insert tags generated by HTML parser - `continueOnParseError` (default: `false`): Handle parse errors instead of aborting ### Whitespace & Formatting - `collapseWhitespace` (default: `false`): Collapse white space that contributes to text nodes in a document tree - `collapseInlineTagWhitespace` (default: `false`): Don't leave any spaces between `display:inline;` elements when collapsing (must be used with `collapseWhitespace=true`) - `conservativeCollapse` (default: `false`): Always collapse to 1 space (never remove it entirely). Must be used with `collapseWhitespace=true` - `preserveLineBreaks` (default: `false`): Always collapse to 1 line break when whitespace between tags include a line break. Must be used with `collapseWhitespace=true` - `trimCustomFragments` (default: `false`): Trim white space around `ignoreCustomFragments` - `noNewlinesBeforeTagClose` (default: `false`): Never add a newline before a tag that closes an element ### Attributes - `removeAttributeQuotes` (default: `false`): Remove quotes around attributes when possible - `collapseBooleanAttributes` (default: `false`): Omit attribute values from boolean attributes - `removeEmptyAttributes` (default: `false`): Remove all attributes with whitespace-only values - `removeRedundantAttributes` (default: `false`): Remove attributes when value matches default - `preventAttributesEscaping` (default: `false`): Prevents the escaping of the values of attributes - `removeTagWhitespace` (default: `false`): Remove space between attributes whenever possible (**Note: this will result in invalid HTML!**) - `sortAttributes` (default: `false`): Sort attributes by frequency ### Comments & Elements - `removeComments` (default: `false`): Strip HTML comments - `processConditionalComments` (default: `false`): Process contents of conditional comments through minifier - `removeEmptyElements` (default: `false`): Remove all elements with empty contents - `removeOptionalTags` (default: `false`): Remove optional tags ### Type Attributes - `removeScriptTypeAttributes` (default: `false`): Remove `type="text/javascript"` from `script` tags. Other `type` attribute values are left intact - `removeStyleLinkTypeAttributes` (default: `false`): Remove `type="text/css"` from `style` and `link` tags. Other `type` attribute values are left intact ### Content Minification - `minifyJS` (default: `false`): Minify JavaScript in script elements and event attributes - `minifyCSS` (default: `false`): Minify CSS in style elements and style attributes - `minifyURLs` (default: `false`): Minify URLs in various attributes ### Document Structure - `useShortDoctype` (default: `false`): Replaces the `doctype` with the short (HTML5) doctype - `keepClosingSlash` (default: `false`): Keep the trailing slash on singleton elements - `decodeEntities` (default: `false`): Use direct Unicode characters whenever possible - `sortClassName` (default: `false`): Sort style classes by frequency ### Advanced Options - `quoteCharacter` (default: `nil`): Type of quote to use for attribute values ("'" or """) - `maxInputLength` (default: `nil`): Maximum input length to prevent ReDoS attacks - `maxLineLength` (default: `nil`): Specify a maximum line length. Compressed output will be split by newlines at valid HTML split-points ### Example with Common Options ```swift let options = HTMLMinifierOptions( removeComments: true, collapseWhitespace: true, removeAttributeQuotes: true, collapseBooleanAttributes: true, removeEmptyAttributes: true, removeRedundantAttributes: true, removeScriptTypeAttributes: true, removeStyleLinkTypeAttributes: true, useShortDoctype: true, minifyJS: true, minifyCSS: true ) ``` ## Error Handling ```swift do { let result = try HTMLMinifier.minify(html) print(result) } catch HTMLMinifierError.jsContextCreationFailed { print("Failed to create JavaScript context") } catch HTMLMinifierError.jsScriptLoadFailed(let message) { print("JavaScript script loading failed: \(message)") } catch HTMLMinifierError.minificationFailed(let message) { print("Minification failed: \(message)") } catch HTMLMinifierError.invalidInput { print("Invalid input") } ``` ## License Licensed under the MIT License.
