JSMin是一个很好的JS压缩工具，只是使用时比较不方便，于是，我给它加了个GUI，增加了多线程支持，这样，可以尽量提高JSMin的操作性。
//核心代码
void JSMinDialog::DoOK(const wxString& srcPath,const wxString& destPath)
{
if(srcPath == destPath)
{
wxLog::OnLog(wxLOG_Error,wxT("源文件目录下输出目录不能是同一个"),time(NULL));
return;
}
wxDir srcDir(srcPath);
wxDir destDir(destPath);
wxArrayString fiels;
size_t srcs = srcDir.GetAllFiles(srcPath, &fiels, wxT("*.js"));
wxString srcFileName;
wxString destFileName;
wxString destFilePath;
for(int i=0; i<fiels.Count(); ++i)
{
srcFileName = fiels.Item(i);
destFileName = srcFileName;
destFilePath = ::wxPathOnly(destFileName);
destFilePath.Replace(srcPath,destPath);
if(!::wxDirExists(destFilePath))
{
if(!::wxMkdir(destFilePath))
{
continue;
}
}
destFileName.Replace(srcPath,destPath);
CJSMin* js = new CJSMin(srcFileName,destFileName,wxT(""));
CJSMinThread* pThread = new CJSMinThread(js);
if(pThread->Create() != wxTHREAD_NO_ERROR)
{
delete js;
wxLog::OnLog(wxLOG_Error,wxT("生成") + destFileName + wxT("错误"),wxDateTime::GetTimeNow());
}
else
{
wxLog::OnLog(wxLOG_Message,wxT("处理")+srcFileName+wxT(" > ") + destFileName,wxDateTime::GetTimeNow());
pThread->Run();
}
}
}

action treats a string as a single character. Wow!
action recognizes a regular expression if it is preceded by ( or , or =.
