nsCoreFoundationBreaker

After talking to @kengggg, we are agree to implement NS_GetComplexLineBreaks without using deprecated UCFindTextBreak. So I try to rewrite nsCarbonBreaker by using Core Foundation API. However I don’t have Mac since 2008 so I didn’t test. In fact, I don’t even try to compile the code.

GIZA++ 1.0.3 บน Ubuntu 9.10

ผมพยายามจะลง Giza++ 1.0.3 บน Ubuntu 9.10 จริงๆ มี .deb ให้ใช้แต่ว่า ผมไม่ได้ใช้เพราะอยากจะ code ของ Giza++ ด้วย

แต่ว่าก็มีปัญหานิดหน่อย เพราะว่า string ที่จองมาเก็บปี จองมาน้อยไปหน่อย คล้ายๆ ปัญหา y2k ก็เลย patch ไปแบบนี้

 	  local->tm_min, local->tm_sec);
   user = getenv("USER");

รายงานบักไปแล้วเหมือนจะซ้ำด้วย http://code.google.com/p/giza-pp/issues/detail?id=20 บรรยากาศก็เงียบๆ
