**{fmt}** is an open-source formatting library for C++.
It can be used as a safe and fast alternative to (s)printf and IOStreams.
It can be used as a safe and fast alternative to (s)printf and iostreams.
`Documentation <http://fmtlib.net/latest/>`__
`Documentation <https://fmt.dev/latest/>`__
This is a development branch that implements the C++ standards proposal `P0645
Text Formatting <http://fmtlib.net/Text%20Formatting.html>`__.
Released versions are available from the `Releases page
<https://github.com/fmtlib/fmt/releases>`__.
Q&A: ask questions on `StackOverflow with the tag fmt <https://stackoverflow.com/questions/tagged/fmt>`_.
Features
--------
* Replacement-based `format API <http://fmtlib.net/dev/api.html>`_ with
* Replacement-based `format API <https://fmt.dev/dev/api.html>`_ with
positional arguments for localization.
* `Format string syntax <http://fmtlib.net/dev/syntax.html>`_ similar to the one
of `str.format <https://docs.python.org/2/library/stdtypes.html#str.format>`_
* `Format string syntax <https://fmt.dev/dev/syntax.html>`_ similar to the one
of `str.format <https://docs.python.org/3/library/stdtypes.html#str.format>`_
in Python.
* Safe `printf implementation
<http://fmtlib.net/latest/api.html#printf-formatting>`_ including
<https://fmt.dev/latest/api.html#printf-formatting>`_ including
the POSIX extension for positional arguments.
* Implementation of `C++20 std::format <https://en.cppreference.com/w/cpp/utility/format>`__.
* Support for user-defined types.
* High speed: performance of the format API is close to that of glibc's `printf
<http://en.cppreference.com/w/cpp/io/c/fprintf>`_ and better than the
performance of IOStreams. See `Speed tests`_ and
`Fast integer to string conversion in C++
* High performance: faster than common standard library implementations of
`printf <https://en.cppreference.com/w/cpp/io/c/fprintf>`_ and
iostreams. See `Speed tests`_ and `Fast integer to string conversion in C++
<http://zverovich.net/2013/09/07/integer-to-string-conversion-in-cplusplus.html>`_.
* Small code size both in terms of source code (the minimum configuration
consists of just three header files, ``core.h``, ``format.h`` and
``format-inl.h``) and compiled code. See `Compile time and code bloat`_.
* Reliability: the library has an extensive set of `unit tests
<https://github.com/fmtlib/fmt/tree/master/test>`_.
<https://github.com/fmtlib/fmt/tree/master/test>`_ and is continuously fuzzed.
* Safety: the library is fully type safe, errors in format strings can be
reported at compile time, automatic memory management prevents buffer overflow
errors.
* Ease of use: small self-contained code base, no external dependencies,
permissive BSD `license
permissive MIT `license
<https://github.com/fmtlib/fmt/blob/master/LICENSE.rst>`_
* `Portability <http://fmtlib.net/latest/index.html#portability>`_ with
* `Portability <https://fmt.dev/latest/index.html#portability>`_ with
consistent output across platforms and support for older compilers.
* Clean warning-free codebase even on high warning levels
(``-Wall -Wextra -pedantic``).
* Support for wide strings.
* Optional header-only configuration enabled with the ``FMT_HEADER_ONLY`` macro.
See the `documentation <http://fmtlib.net/latest/>`_ for more details.
See the `documentation <https://fmt.dev/latest/>`_ for more details.
Examples
--------
This prints ``Hello, world!`` to stdout:
Print ``Hello, world!`` to ``stdout``:
.. code:: c++
fmt::print("Hello, {}!", "world"); // uses Python-like format string syntax
fmt::printf("Hello, %s!", "world"); // uses printf format string syntax
fmt::print("Hello, {}!", "world"); // Python-like format string syntax
fmt::printf("Hello, %s!", "world"); // printf format string syntax
Arguments can be accessed by position and arguments' indices can be repeated:
Format a string and use positional arguments:
.. code:: c++
std::string s = fmt::format("{0}{1}{0}", "abra", "cad");
// s == "abracadabra"
std::string s = fmt::format("I'd rather be {1} than {0}.", "right", "happy");
// s == "I'd rather be happy than right."
Format strings can be checked at compile time:

`print <https://fmt.dev/latest/api.html#print>`_
which take arbitrary arguments (`godbolt <https://godbolt.org/g/MHjHVf>`_):
.. code:: c++
// Prints formatted error message.
void vreport_error(const char *format, fmt::format_args args) {
void vreport_error(const char* format, fmt::format_args args) {
fmt::print("Error: ");
fmt::vprint(format, args);

Motivation
----------
So why yet another formatting library?
There are plenty of methods for doing this task, from standard ones like
the printf family of function and IOStreams to Boost Format library and
FastFormat. The reason for creating a new library is that every existing
solution that I found either had serious issues or didn't provide
all the features I needed.
Printf
~~~~~~
The good thing about printf is that it is pretty fast and readily available
being a part of the C standard library. The main drawback is that it
doesn't support user-defined types. Printf also has safety issues although
they are mostly solved with `__attribute__ ((format (printf, ...))
<http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html>`_ in GCC.
There is a POSIX extension that adds positional arguments required for
`i18n <https://en.wikipedia.org/wiki/Internationalization_and_localization>`_
to printf but it is not a part of C99 and may not be available on some
platforms.
IOStreams
~~~~~~~~~
The main issue with IOStreams is best illustrated with an example:
.. code:: c++
std::cout << std::setprecision(2) << std::fixed << 1.23456 << "\n";
which is a lot of typing compared to printf:
.. code:: c++
printf("%.2f\n", 1.23456);
Matthew Wilson, the author of FastFormat, referred to this situation with
IOStreams as "chevron hell". IOStreams doesn't support positional arguments
by design.
The good part is that IOStreams supports user-defined types and is safe
although error reporting is awkward.
Boost Format library
~~~~~~~~~~~~~~~~~~~~
This is a very powerful library which supports both printf-like format
strings and positional arguments. Its main drawback is performance.
According to various benchmarks it is much slower than other methods
considered here. Boost Format also has excessive build times and severe
code bloat issues (see `Benchmarks`_).
FastFormat
~~~~~~~~~~
This is an interesting library which is fast, safe and has positional
arguments. However it has significant limitations, citing its author:
Three features that have no hope of being accommodated within the
current design are:
* Leading zeros (or any other non-space padding)
* Octal/hexadecimal encoding
* Runtime width/alignment specification
It is also quite big and has a heavy dependency, STLSoft, which might be
too restrictive for using it in some projects.
Loki SafeFormat
~~~~~~~~~~~~~~~
SafeFormat is a formatting library which uses printf-like format strings
and is type safe. It doesn't support user-defined types or positional
arguments. It makes unconventional use of ``operator()`` for passing
format arguments.
Tinyformat
~~~~~~~~~~
This library supports printf-like format strings and is very small and
fast. Unfortunately it doesn't support positional arguments and wrapping
it in C++98 is somewhat difficult. Also its performance and code compactness
are limited by IOStreams.
Boost Spirit.Karma
~~~~~~~~~~~~~~~~~~
This is not really a formatting library but I decided to include it here
for completeness. As IOStreams it suffers from the problem of mixing
verbatim text with arguments. The library is pretty fast, but slower
on integer formatting than ``fmt::Writer`` on Karma's own benchmark,
see `Fast integer to string conversion in C++
<http://zverovich.net/2013/09/07/integer-to-string-conversion-in-cplusplus.html>`_.
Benchmarks
----------
Speed tests
~~~~~~~~~~~
The following speed tests results were generated by building
``tinyformat_test.cpp`` on Ubuntu GNU/Linux 14.04.1 with
``g++-4.8.2 -O3 -DSPEED_TEST -DHAVE_FORMAT``, and taking the best of three
runs. In the test, the format string ``"%0.10f:%04d:%+g:%s:%p:%c:%%\n"`` or
equivalent is filled 2000000 times with output sent to ``/dev/null``; for
further details see the `source
<https://github.com/fmtlib/format-benchmark/blob/master/tinyformat_test.cpp>`_.

{fmt} 6.1.1 fmt::print 0.75
Boost Format 1.67 boost::format 7.24
Folly Format folly::format 2.23
================= ============= ===========
As you can see ``boost::format`` is much slower than the alternative methods; this
is confirmed by `other tests <http://accu.org/index.php/journals/1539>`_.
Tinyformat is quite good coming close to IOStreams. Unfortunately tinyformat
cannot be faster than the IOStreams because it uses them internally.
Performance of fmt is close to that of printf, being `faster than printf on integer
formatting <http://zverovich.net/2013/09/07/integer-to-string-conversion-in-cplusplus.html>`_,
but slower on floating-point formatting which dominates this benchmark.
{fmt} is the fastest of the benchmarked methods, ~35% faster than ``printf``.
The above results were generated by building ``tinyformat_test.cpp`` on macOS
10.14.6 with ``clang++ -O3 -DSPEED_TEST -DHAVE_FORMAT``, and taking the best of
three runs. In the test, the format string ``"%0.10f:%04d:%+g:%s:%p:%c:%%\n"``
or equivalent is filled 2,000,000 times with output sent to ``/dev/null``; for
further details refer to the `source
<https://github.com/fmtlib/format-benchmark/blob/master/tinyformat_test.cpp>`_.
{fmt} is 10x faster than ``std::ostringstream`` and ``sprintf`` on floating-point
formatting (`dtoa-benchmark <https://github.com/fmtlib/dtoa-benchmark>`_)
and as fast as `double-conversion <https://github.com/google/double-conversion>`_:

contents of the format string referred to by ``ctx.begin()`` so the object will
always be formatted in the same way. See ``formatter<tm>::parse`` in

# FMT Fuzzer
Fuzzing has revealed [several bugs](https://github.com/fmtlib/fmt/issues?&q=is%3Aissue+fuzz)
in fmt. It is a part of the continous fuzzing at
[oss-fuzz](https://github.com/google/oss-fuzz).
The source code is modified to make the fuzzing possible without locking up on
resource exhaustion:
```cpp
#ifdef FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION
if(spec.precision>100000) {
throw std::runtime_error("fuzz mode - avoiding large precision");
}
#endif
```
This macro is the defacto standard for making fuzzing practically possible, see
[the libFuzzer documentation](https://llvm.org/docs/LibFuzzer.html#fuzzer-friendly-build-mode).
## Running the fuzzers locally
There is a [helper script](build.sh) to build the fuzzers, which has only been
tested on Debian and Ubuntu linux so far. There should be no problems fuzzing on
Windows (using clang>=8) or on Mac, but the script will probably not work out of
the box.
Something along
```sh
mkdir build
cd build
export CXX=clang++
export CXXFLAGS="-fsanitize=fuzzer-no-link -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION= -g"
cmake .. -DFMT_SAFE_DURATION_CAST=On -DFMT_FUZZ=On -DFMT_FUZZ_LINKMAIN=Off -DFMT_FUZZ_LDFLAGS="-fsanitize=fuzzer"
cmake --build .
```
should work to build the fuzzers for all platforms which clang supports.
Execute a fuzzer with for instance
```sh
cd build
export UBSAN_OPTIONS=halt_on_error=1
mkdir out_chrono
bin/fuzzer_chrono_duration out_chrono
```
