Should compression throw any exceptions or catch them? 6 | - Look into error logging (java.util.logging, log4j, slf4j bridge?) 7 | - Look into possibility of creating complex js/css/html compression solution that produces googleplus-like compression results [shrinking css classes](https://github.com/hazendaz/htmlcompressor/issues/46) 8 | 9 | If you have any suggestions about features listed (or not listed) above please create an [Issue report](https://github.com/hazendaz/htmlcompressor/issues). 10 | --------------------------------------------------------------------------------

page [here](https://hazendaz.github.io/htmlcompressor/) 11 | 12 | Small, fast and very easy to use Java library that minifies given HTML or XML source by removing extra whitespaces, comments and other unneeded characters without breaking the content structure. As a result pages become smaller in size and load faster. A command-line version of the compressor is also available. 13 | 14 | ## PACKAGE CONTENT ## 15 | - ```/bin``` contains main ${project.artifactId}-${project.version}.jar binary, as well as several extra jars (could be useful for IDE integration) 16 | - ```/doc``` javadocs 17 | - ```/src``` sources 18 | - ```/lib``` dependencies (for using with a command line compressor or non-Maven projects) 19 | - ```pom.xml``` Maven POM file 20 | 21 | ## USAGE ## 22 | - For java projects add ${project.artifactId}-${project.version}.jar library to your project's classpath 23 | - For a command line usage run: ```java -jar ${project.artifactId}-${project.version}.jar -h``` to get a brief description of available parameters. 24 | 25 | Please refer to http://code.google.com/p/htmlcompressor/ for the detailed documentation. 26 | 27 | ## PROJECT BUILD ## 28 | - Install JDK 11+ (https://www.oracle.com/java/technologies/downloads/) 29 | - Install Maven 3.9.1+ (http://maven.apache.org/download.html) 30 | - Run build.bat or build.sh 31 | - Compiled binaries will be placed in /target subdirectory 32 | 33 | ## CHANGELOG ## 34 | - Changelog for 1.5.3 and before found [here](CHANGELOG.md) 35 | 36 | ## Looking to help ## 37 | - A lot of docuemntation is still at google code, a good getting started pull request would be to work on translate that data over. The original export only exported the issues and source code. Thus far the TODO wiki is 100% copied over, The change log is copied over too but missing links. Need all documentation copied over. 38 | -------------------------------------------------------------------------------- /src/main/java/com/googlecode/htmlcompressor/compressor/YuiCssCompressor.java: -------------------------------------------------------------------------------- 1 | /* 2 | * Copyright 2009-2025 the original author or authors. 3 | * 4 | * Licensed under the Apache License, Version 2.0 (the "License"); 5 | * you may not use this file except in compliance with the License. 6 | * You may obtain a copy of the License at 7 | * 8 | * https://www.apache.org/licenses/LICENSE-2.0 9 | * 10 | * Unless required by applicable law or agreed to in writing, software 11 | * distributed under the License is distributed on an "AS IS" BASIS, 12 | * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 13 | * See the License for the specific language governing permissions and 14 | * limitations under the License. 15 | */ 16 | package com.googlecode.htmlcompressor.compressor; 17 | 18 | import com.yahoo.platform.yui.compressor.CssCompressor; 19 | 20 | import java.io.IOException; 21 | import java.io.StringReader; 22 | import java.io.StringWriter; 23 | 24 | import org.slf4j.Logger; 25 | import org.slf4j.LoggerFactory; 26 | 27 | /** 28 | * Basic CSS compressor implementation using Yahoo YUI 29 | * Compressor that could be used by {@link HtmlCompressor} for inline CSS compression. 30 | * 31 | * @see HtmlCompressor#setCssCompressor(Compressor) 32 | * @see Yahoo YUI Compressor 33 | */ 34 | public class YuiCssCompressor implements Compressor { 35 | 36 | /** The Constant Logger. */ 37 | private static final Logger logger = LoggerFactory.getLogger(YuiCssCompressor.class); 38 | 39 | /** The line break. */ 40 | private int lineBreak = -1; 41 | 42 | @Override 43 | public String compress(String source) { 44 | StringWriter result = new StringWriter(); 45 | 46 | try { 47 | CssCompressor compressor = new CssCompressor(new StringReader(source)); 48 | compressor.compress(result, lineBreak); 49 | } catch (IOException e) { 50 | result.write(source); 51 | logger.error("", e); 52 | } 53 | 54 | return result.toString(); 55 | } 56 | 57 | /** 58 | * Returns number of symbols per line Yahoo YUI Compressor will use during CSS compression.

Disclaimer of Warranty. Unless required by applicable law or 145 | agreed to in writing, Licensor provides the Work (and each 146 | Contributor provides its Contributions) on an "AS IS" BASIS, 147 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or 148 | implied, including, without limitation, any warranties or conditions 149 | of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A 150 | PARTICULAR PURPOSE.
