The last Loki thread I see here is the one from 2002 discussing adding Loki to Boost. I asked Andrei once about doing that specifically for the Loki SafeFormat functions (FPrint, Printf, and SPrintf) and he said FPrintf wasn't good enough yet. However, I find all of them very useful and would love to see them added to the Boost library I know Boost has Format now, but SafeFormat has some advantages over Boost.Format, one of which is that FPrintf can be output to C++ streams as well as to FILE pointers--very handy when one is gradually converting legacy code to using C++ streams. In addition, I find the SafeFormat family much easier to use than Boost.Format. Andrei's original comments regarding FPrintf's shortcomings are here: https://sourceforge.net/forum/message.php?msg_id=4525195 His "Dr. Dobb's Journal" article describing SafeFormat is here: http://www.ddj.com/cpp/184401987 Thank you for your consideration.
