Hi all! I'm Shuai Meng, a student from software school of Beihang University, China, GMT+08:00. I'm pursuing a master degree and now in grade one. You can call me shuaimeng, that's my nickname used in irc. Now I'm here to apply for GSoC to work for Wine. I'm familiar with C, and I can code with python as well. Besides, I know a little about html and vbscript. From May to August, I have plenty of free time.
About one year ago I started my way to linux, it's not smooth for a person who had got used to windows then embrace linux. Soon I got a problem: QQ(the most popular IM software in China) doesn't support linux, but I really need it. Fortunately I knew wine through searching google, it helped me solve this problem.Since then I have become a wine user.
In the past three months, I had focused on dlls/vbscript/global.c, searching MSDN for related documents[1]~[4]. Accordding those documents, I added more tests in dlls/vbscript/tests/api.vbs, then got some similar bugs and only reported one[5]. In order to fix them, I read wine source code in dlls/vbscript/global.c, again and again. Finally I finished a few draft patches[6] and I will send them to wine-patches later.
As I have made so much effort in this module and gain a little experience, during GSoC this part will go on to occupy most of my attention. On the basis of difficulty to be implemented, I divide all the functions in dlls/vbscript/global.c into four groups as following:
1: Abs ScriptEngine ScriptEngineBuildVersion ScriptEngineMajorVersion IsArray IsDate IsNumeric IsObject Sgn TypeName VarType
These are the easiest to implement, I will take about one week to finish the unimplemented.
2: FormatCurrency FormatDateTime FormatPercent Hour FormatNumber Join Minute Month Oct Rnd Second Space TimeValue Year
The second group will occupy two weeks of the whole GSoC time. They are not as easy as the first group and there are more to be accomplished. Most of them are involved in time functions while a few is about strings.
3: Asc Ant Cos DateAdd DateDiff DatePart DateSerial Day Exp LBound Log Replace Sin Sqr String Tan TimeSerial UBound Weekday CBool CByte CCur CDate CDbl CInt CLng CSng CStr InStrRev Int Fix StrComp Timer
These are more difficult. However a large part is conversion functions and they have been implemented or improved by me. You can find the details in attchment. Optimistically speaking, I need at least three weeks to complete all of them. When I finish that, this bug[7] will be fixed.
4: Array Date DateValue Escape Eval Filter GetLocale GetRef InputBox LoadPicture Now RGB SetLocale Split Time Unescape
Here come the most difficult ones. I am not so sure whether I can fix or even understand them, but I will try my best. Maybe after I have finish the above three groups, I can gain a little confidence to face them. This group would cost me four weeks or even longer. If I have a good luck, maybe I can fix this bug[8].
To be prudent, I'll spare at least one week to do a review on all my codes. Write a summary as a guidence for my work to be continued after GSoC.
Though I have a rough plan now, as a greenhand to wine, I hava too much to learn and I badly need advice from all of you. I hope I can make a proper schedule after communicating with my mentor.
Any comment or advice is greatly appreciated. Thank you!
