工作中需要优化代码里的中文警示语和异常信息,实在比较多,所以就写了个程序专门从代码里提取中文字符串。
java做的,比较简单,放上来备忘
package com.extractstr.app;
import java.io.*;
import java.util.*;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
/**
* 搜索字符串并输出到控制台
*/
public class ExtractStr {
public static String getHelpString(String[] args){
String result = String.format("%s [path]", new Object[]{"a"});
return result;
}
private void getFiles(String rootPath, final String fileExt, List<File> fileList){
File f =new File(rootPath);
File[] list=f.listFiles(new FileFilter() {
@Override
public boolean accept(File f) {
boolean ret = f.isDirectory() || (f.isFile() && f.getName().endsWith(fileExt));
return ret;
}
});
for(File fn : list){
if (fn.isDirectory()){
this.getFiles(fn.getAbsolutePath(), fileExt, fileList);
}else{
fileList.add(fn);
}
}
}
public List<File> run(String rootPath, String fileExt){
List<File> result = new LinkedList<File>();
this.getFiles(rootPath, fileExt, result);
return result;
}
public List<String> parserSourceFile(List<String> patternList, File file, int miniCharCount) throws Exception {
List<String> result = new LinkedList<String>();
BufferedReader r = new BufferedReader(new FileReader(file));
char[] buffer = new char[(int)file.length()];
r.read(buffer, 0, (int)file.length());
String text=new String(buffer, 0, buffer.length);
for(String patternStr : patternList){
//Pattern pattern = Pattern.compile("\"(.*?)\"");
Pattern pattern = Pattern.compile(patternStr);
Matcher matchers= pattern.matcher(text);
while(matchers.find()){
String t=matchers.group();
if (t.length()>=miniCharCount)
result.add(t);
}
}
return result;
}
public static void main(String []args){
if (args.length==0){
StringBuilder sb = new StringBuilder()
.append("未传入需要搜索的有效的源代码路径")
.append("\n")
.append(ExtractStr.getHelpString(args));
System.out.println(sb.toString());
System.exit(1);
}
List<String> searchFolders=new ArrayList<String>(100);
for(int i=0; i<=args.length-1;i++){
File f=new File(args[i]);
if (!f.isDirectory() || !f.exists())
continue;
searchFolders.add(f.getAbsolutePath());
}
List<String> patternList = new LinkedList<String>();
patternList.add("‘([\\u4E00-\\u9FA5]+)‘");
patternList.add("\"([\\u4E00-\\u9FA5]+)\"");
ExtractStr es = new ExtractStr();
List<File> fileList = new ArrayList<File>(1000);
for(String sarchFolder : searchFolders){
List<File> t=es.run(sarchFolder, ".php");
fileList.addAll(t);
}
Set<String> outList=new HashSet<String>();
for(File f : fileList){
try{
List<String> items=es.parserSourceFile(patternList, f, 12);
outList.addAll(items);
}catch(Exception e){
e.printStackTrace();
}
}
for(String str : outList){
System.out.println(str);
}
}
}
对于拼接字符串的中文输出支持的不算好,而且也对中文的长度有限制(最少12个字符)
