Is FastFormat dead?

Mikko Koivunalho — Fri, 22 Apr 2016 17:44:57 -0000

The FastFormat and Pantheios repositories are available in Github.
https://github.com/synesissoftware/FastFormat and
https://github.com/synesissoftware/Pantheios

If you use CMake as build tool, I have converted FastFormat to a CMake project for (CMake style) importing. Newest version of FastFormat is 0.7.1 from 26th September 2015.

Is FastFormat dead?

Are you still working active on Fastformat (Still alive?) or should i you Pantheios ?

What i am doing wrong (fastformat 0.7.1)

Hi,

i currently got the same problelm like this one:
https://sourceforge.net/p/fastformat/discussion/612782/thread/73c4033d/

On my Win7 64bit System the variables look like:

FASTFORMAT_ROOT=C:\Fastformat\fastformat-0.7.1
STLSOFT=C:\Fastformat\stlsoft-1.9.124

the INCLUDE Path of the project logger is extended with "C:\Fastformat\fastformat-0.7.1\include;C:\Fastformat\stlsoft-1.9.124\include;"
the Lib Path ist extended with "C:\Fastformat\fastformat-0.7.1\bin;"

My sample code looks like and should be compiled with Unicode:

#include <fastformat/fastformat.hpp>
#include <fastformat/sinks/ostream.hpp>
#include <iostream>
#include <string>

int main()
{
    char         arg0[] = "abc";
    std::string  arg1 = "def";
    int          arg2 = -101;

    std::string  result;

    // format to a string
    fastformat::fmt(result, "Arguments in arbitrary order, such as {2}, {0} and {1}", arg0, arg1, arg2);

    // format to cout, with a newline
    fastformat::fmtln(std::cout, "Arguments in arbitrary order, such as {2}, {0} and {1}", arg0, arg1, arg2);

    return 0;
}

If i compile it with Visual Studio 2013 i receive a couple errors like:

api_functions.hpp(294): error C2665: 'fastformat::c_str_len_w' : none of the 4 overloads could convert all the argument types

How can i resolve this issue and compile correctly ?

Did the steps given in the following url

Building on gcc 4.8.1, Debina GNU/Linux wheezy/sid

to get fastformat to compile. Compiled fine and all tests were successful.

The following code

#include <fastformat/fastformat.hpp>
#include <fastformat/sinks/ostream.hpp>
#include <fastformat/inserters/to_f.hpp>

#include <string>
#include <iostream>

int main() {

    float       flot    =       25.5;
    std::string sink;

    fastformat::write(sink, fastformat::to_f(flot) );

    return 0;
}

was compiled the following way

g++ -g fastformatfloattest.cpp -o fastformatfloattest -lfastformat.0.core.gcc47

and terminated with SIGABRT (06) signal on line

fastformat::write(sink, fastformat::to_f(flot) );

upon execution with the following output

fastformatfloattest: /usr/include/fastformat/inserters/real.hpp:421: stlsoft::basic_shim_string<char, 64ul> fastformat::inserters::real(const double&, int, int, fastformat::ff_char_t): Assertion `(FASTFORMAT_TYPECHECK_MSG_("maximum value for width exceeded") && (abs(minimumWidth) < 512))' failed.
Aborted (core dumped)

fastformat::to_f calls fastformat::inserters::real with the following arguments

value
real_impl::default_width_sentinel_(),
real_impl::default_precision_sentinel_(),
'f'

where real_impl::default_width_sentinel (minimumWidth in fastformat::inserters::real) returns stlsoft::limit_traits<int>::minimum(), which outputs -2147483648 on my system.

I am facing the same issue. Did you find a solution?

just one more comment:

when building using command: nmake build
I receive error:
D:\3pty\cpp_fast_format\fastformat-0.7.1\include\fastformat/sinks/CComBSTR.hpp(79) : fatal error C1083: Cannot open include file: 'atlbase.h': No such file or directory
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\BIN\cl.EXE"' : return code '0x2'

The problem is with atlbase.h which (as far as I found) does not come with vs c++ Express edition.

Not sure if this is also a reason for the error I receive when trying to build my code.

Hi,
I am quite new to C++ (coming from .NET environment) and I am trying to use FastFormat in VS C++ (Express 2012 for Windows Desktop).
I did the following steps following what I have found in the FAQ:
1.
download and unzip FastFormat and STLSoft to:
D:\3pty\cpp_fast_format\fastformat-0.7.1
D:\3pty\stlsoft-1.9.124
2.
open VS2012 x64 Cross Tools Command Prompt
change directory to D:\3pty\cpp_fast_format\fastformat-0.7.1\build\vc12
3.
define environment variables:
SET STLSOFT=D:\3pty\stlsoft-1.9.124
SET FASTFORMAT_ROOT=D:\3pty\cpp_fast_format\fastformat-0.7.1
4.
run the following command:
nmake build.libs.core
5.
in Configuration Properties --> C/C++ --> General
define Additional Include Directories: D:\3pty\cpp_fast_format\fastformat-0.7.1\include; D:\3pty\stlsoft-1.9.124\include
6.
in Configuration Properties --> Linker --> General
define Additional Include Directories: D:\3pty\cpp_fast_format\fastformat-0.7.1\lib
7.
in Configuration Properties --> General
change Character Set from Use Unicode Character Set to Use Multi-Byte Character Set

Now here is my "program":

#include<iostream>
#include <string>
#include <fastformat fastformat.hpp="">

#define FASTFORMAT_NO_VERSION_NAG

using namespace std;

int main()
{

   std::string             sink;
   char const*             arg0    =   "arg0";

   sink.erase();
   fastformat::fmt(sink, "A c-style string: {0}", arg0);

   cout<<"\npress ENTER...";cin.get();
   return 0;

}

now, when trying to build it I get the following error messages:

main.obj : error LNK2019: unresolved external symbol _fastformat_init referenced in function "public: thiscall fastformat::fastformat_initialiser::fastformat_initialiser(void)" (??0fastformat_initialiser@fastformat@@QAE@XZ)
1>main.obj : error LNK2019: unresolved external symbol _fastformat_uninit referenced in function "public: thiscall fastformat::fastformat_initialiser::~fastformat_initialiser(void)" (??1fastformat_initialiser@fastformat@@QAE@XZ)
etc etc...

Could not find any more suggestion in FAQ. I would appreciate any suggestions! Thanks!

Hi there, We are using jenkins for CI and want to buil vc8 32 / 64 bit & vc11 32 / 64 bit libraries.
The same script can build vc11 64-bit but vc8 32-bit exist an error.
Please help me, thx.
