Pantheios 1.0.1 beta 215 introduces the showPlus format flag, which causes leading pluses to be applied to integers (just as leading minuses will appear for negative numbers).
It is used as follows:
#include <pantheios/pan.hpp>
#include <pantheios/inserters/i.hpp>
int main()
{
pan::log_INFORMATIONAL("log -10:");
pan::log_INFORMATIONAL("without showPlus: '", pan::i(-10), "'");
pan::log_INFORMATIONAL("with showPlus: '", pan::i(-10, 0, pan::fmt::showPlus), "'");
pan::log_INFORMATIONAL("----------\n");
pan::log_INFORMATIONAL("log +10:");
pan::log_INFORMATIONAL("without showPlus: '", pan::i(+10), "'");
pan::log_INFORMATIONAL("with showPlus: '", pan::i(+10, 0, pan::fmt::showPlus), "'");
pan::log_INFORMATIONAL("----------\n");
pan::log_INFORMATIONAL("log -10 into 10-width:");
pan::log_INFORMATIONAL("without showPlus: '", pan::i(-10, 10, 0), "'");
pan::log_INFORMATIONAL("with showPlus: '", pan::i(-10, 10, pan::fmt::showPlus), "'");
pan::log_INFORMATIONAL("----------\n");
pan::log_INFORMATIONAL("log +10 into 10-width:");
pan::log_INFORMATIONAL("without showPlus: '", pan::i(+10, 10, 0), "'");
pan::log_INFORMATIONAL("with showPlus: '", pan::i(+10, 10, pan::fmt::showPlus), "'");
pan::log_INFORMATIONAL("----------\n");
pan::log_INFORMATIONAL("log -10 into 10-width left-justified:");
pan::log_INFORMATIONAL("without showPlus: '", pan::i(-10, -10, 0), "'");
pan::log_INFORMATIONAL("with showPlus: '", pan::i(-10, -10, pan::fmt::showPlus), "'");
pan::log_INFORMATIONAL("----------\n");
pan::log_INFORMATIONAL("log +10 into 10-width left-justified:");
pan::log_INFORMATIONAL("without showPlus: '", pan::i(+10, -10, 0), "'");
pan::log_INFORMATIONAL("with showPlus: '", pan::i(+10, -10, pan::fmt::showPlus), "'");
pan::log_INFORMATIONAL("----------\n");
return 0;
}
PANTHEIOS_EXTERN_C PAN_CHAR_T const PANTHEIOS_FE_PROCESS_IDENTITY[] = PANTHEIOS_LITERAL_STRING("test.scratch.showPlus.integer");
which gives the output:
[test.scratch.showPlus.integer...]: log -10:

Pantheios 1.0.1 beta 215 released
Pantheios is an open source C/C++ Logging API library, offering an optimal
combination of 100% type-safety, efficiency, genericity and extensibility.
It is simple to use and extend, highly-portable (platform and
compiler-independent) and, best of all, it upholds the C tradition of you
only pay for what you use.
Pantheios supports logging of message statements of arbitrary complexity,
consisting of heterogeneous types.
Pantheios supports filtering of log messages based on severity level
including (but not limited to) the eight levels defined by the SysLog
protocol.
Pantheios supports back-end output, individually and in combination, to
stderr/stdout, SysLog (including a custom implementation of the SysLog
protocol for Windows), Windows debugger, Windows event log, COM Error
Object, Speech, or any custom back-end extension you care to write.
Importantly, Pantheios is readily extended to use the existing transport
mechanisms of feature-rich logging libraries such as ACE, log4cpp,
log4cplus, log4cxx.
Pantheios does not contain any compiler-specific or platform-specific
constructs. It supports UNIX (including Linux and Mac OS-X), and Windows,
and should work with any operating system. It is known to be compatible with
Borland (5.6+), Clang, Comeau (4.3.3+), Digital Mars (8.45+), GCC (3.4+), Intel
(7+), Metrowerks (8+), Microsoft Visual C++ (6.0+), and should work with any
reasonably modern C++ compiler.
Pantheios is completely free and includes source released under a BSD-style
license. Commercial servics, including bespoke customisations, are available
from Synesis Software Pty Ltd; http://synesis.com.au/contact.html
Pantheios Training is provided by Synesis Software Pty Ltd; details at

Release 1.0.1 beta 215 incorporates:
* added interval inserter
* added stream_character inserter
* Clang-compatibility
* VC++ 11-compatibility
* VC++ 12-compatibility
* VC++ 14-compatibility
* showPlus format flag support in pantheios::integer (pan::i)
* makefiles customisable to specify non-bundled locations of b64, shwild,
xContract, xCover, and xTests libraries (useful to getting head from GitHub)
* NOTE: Now requires STLSoft 1.9.121

Pantheios 1.0.1 beta 197 released: pantheios::integer inserter now more disciplined in width behaviour when hex formatting
The latest release of Pantheios provides substantial reworking of the pantheios::integer inserter class, including how it handles minimum-width specifiers when formatting in hex. Previously, as a statement such as
would have resulted in the output of a line such as:
[old_int_hex.4312, 19/10/2010 7:38:53.062 AM; Debug]: n= 13
With the (surprisingly involved!) changes in 1.0.1 beta 197, the line produces output such as:
[old_int_hex.488, 19/10/2010 7:45:24.625 AM; Debug]: n=0x13
Note the absence of the two spaces - between n= and 13 - that were previously associated with expanding 13 to a minimum width of four. (Anyone who's used printf() can guess how that came about.)
Since these are only minimum widths, this change is unlikely to upset any log processing, but it's possible, so be advised.
#include <pantheios/inserters/integer.hpp>
#include <pantheios/pan.hpp>
int n = 0x13;
pan::log_DEBUG("n=", pan::integer(n, 4, pan::fmt::hex));
pan::log_DEBUG("n=", pan::integer(n, 4, pan::fmt::hex));
would have resulted in the output of a line such as:
[old_int_hex.4312, 19/10/2010 7:38:53.062 AM; Debug]: n= 13
With the (surprisingly involved!) changes in 1.0.1 beta 197, the line produces output such as:
