Re: calling function objects in a fusion vector

Extracting function pointer from function template is difficult.
In this case, it seems even impossible.
BTW, Boost.Egg: http://p-stade.sourceforge.net/boost/libs/egg/
supports "fusing", which turns function into one taking a FusionSequence.

// \f -> fuse(f)(args)
lazy(lazy(fuse)(bll::_1))(args)

Or, this might be more readable.
// \f -> apply(fuse(f), args)
lazy(apply)(lazy(fuse)(bll::_1), args)

Thanks, I will check out the link.  Another similar question is: Can I
use boost to write TCP/UDP socked based program?  Thanks.

Re: Eclipse integration of bjam


Hi Sebastian (or anyone else),

I am trying to integrate bjam with Eclipse and I am able to compile my
project. The only thing is that the output of bjam is written to Eclipse's
console-window and I am not able to navigate through the errors and
warnings. I expected some option to send the output to Eclipe's
problems-window enabling me to navigate through warnings and errors. Is this
currently by any means possible (I am using Eclipse 3.2.2)?

Cheers,
Andrej

Problems on using ostringstream with boost.format and boost.xpressive

Hi,

the following code did not work as expected:

--8<---
#include <iostream>
#include <sstream>
#include <boost/format.hpp>
#include <boost/xpressive/xpressive.hpp>

using namespace boost::xpressive;

int main()
{
     std::string input(
         "the answer is\r42"
         );

     const std::string f( "[Input]\n%1%\n|\n" );
     std::ostringstream oss;

#if 0
     oss << boost::format( f )
         % input
         ;
#else
     oss << input;
#endif

     sregex re = as_xpr("\r");

Thanks john. I ended up using the following:

 bjam --toolset=msvc-9.0 --build-type=complete define=_CRT_SECURE_NO_WARNINGS define=_SCL_SECURE_NO_WARNINGS define=_SECURE_SCL=0 stage | tee BuildLog.txt

 

Without "--build-type=complete" only the release multi-threaded libraries were build. This wasn't the case with 1.3.3.1, and there seems to reference to this in the docs.

 

I would like the following in debug builds:

 define=_SECURE_SCL=1

And this in release builds:

 define=_SECURE_SCL=0

 

I'm not having much luck. Again, any insights would be greatly appreciated.

 

Steve

Just an update on that project:

There is some code in the SVN repository that I did as a "proof of 
concept" of using asio to control tcp/udp and serial i/o in a 
multithreaded, user configurable environment. So it is a complete hack.

We are just beginning to look at a better abstraction for the serial 
capability now, so it will be a little time before anything might be 
ready on the project.

You have to explicitly request whatever variants you want, for example:

        bjam toolset=msvc-9.0 debug/define=_SECURE_SCL=1 release/define=_SECURE_SCL=0

Refactoring


Hi all,

I'm trying to write a parser which can write on the input string (mainly
insert string at the current position).

Does spirit contain any stuff that can help me in that way ?

Thanks,
Jean

Using boost::gregorian (date_time) date with wide strings


Is it possible to use the boost date_time date class with wide strings?  ie.

        std::wstring toConvert(L"12/12/2008");
        date myDate;

        myDate = from_simple_string(toConvert);

What do I have to do to enable this?  I see the library is using std::string only.

Thanks.

(sorry, newbie post).

No problem!  I appreciate the ideas.  I have tried a few tweaks with
no success, but I will continue to experiment and I'll post back if I
find a solution.  Thanks again for your help.
