[iostreams] inverse and "stateful" filters
by EMalenfant＠interstarinc.com 22 Mar '06

22 Mar '06

Hi, I wanted an InputFilter for removing comments from C++ source files. Since it seemed easier to write an OutputFilter, I decided to write that, and use iostreams::inverse to make an InputFilter out of it. However, it seems that inverse can't be used with "stateful" filters. Consider the following, using dictionary_output_filter from the tutorial: (http://www.boost.org/libs/iostreams/doc/index.html?path=2.2.6.3) namespace io = boost::iostreams; const std::string source("This foo … [View More]

I'll go off and nag the people responsible ;-> Well, surprisingly enough (because, as I understand it, gcc on HP-UX does not support multi-threading), that worked! Thanks for your help, John!

They specify the size of the match object, as well as the exact portions of the string to capture. This line should read as follows: boost::regex oDateReg2( "(\\d{2})-(\\d{2})-(\\d{4})" ); or if you wish to allow single-digit months … [View More]

boost, COM and .NET [maybe OT]

Hello there, I'd like to thank Alan for the reply to my previous post. I'm sorry if this message is OT. What I ask is not a technical detail, but an opinion from you, c++ gurus :) Finally I've setup a simply class hierarchy that derives from a common object. Each class has: 1) Smart Pointer (boost::intrusiveptr),typedef intrusiveptr<ClassName> ClassName_Ptr; 2) Array of smart pointers ( typedef array <ClassName_Ptr> ClassName_Array) Everything works fine , and I'm happy :) the … [View More]

Boost.Regex - why does it core dump?
by Smith Matt - matsmi 22 Mar '06

22 Mar '06

I have built Boost 1.33.1 on a HP-UX 11.22 OS with GCC 4.02. I have created a little test program, and when it gets to the following line of code it core dumps. boost::regex Exp( "[0-9]" ); This happens when I link both statically or dynamically. Any insights into what might be the problem would be greatly appreciated.

file-system "system_complete()" and C:/

The following is a note of my developers that was attached to a bug close report. Is this special check for to convert "x:" to "x:/" a good practice for the Boost file-system library usage? Is there a better way to do this and/or are we missing something? -Matt The boost system_complete() function is used to convert relative paths into absolute paths. For some reason, boost interprets 'c:' as an incomplete path, and the windows boost behavior is to initially complete the path to the … [View More]
