# Features
- Simple [format API](https://fmt.dev/latest/api/) with positional
arguments for localization
- Implementation of [C++20
std::format](https://en.cppreference.com/w/cpp/utility/format) and
[C++23 std::print](https://en.cppreference.com/w/cpp/io/print)
- [Format string syntax](https://fmt.dev/latest/syntax/) similar
to Python\'s
[format](https://docs.python.org/3/library/stdtypes.html#str.format)
- Fast IEEE 754 floating-point formatter with correct rounding,
shortness and round-trip guarantees using the
[Dragonbox](https://github.com/jk-jeon/dragonbox) algorithm
- Portable Unicode support
- Safe [printf
implementation](https://fmt.dev/latest/api/#printf-formatting)
including the POSIX extension for positional arguments
- Extensibility: [support for user-defined
types](https://fmt.dev/latest/api/#formatting-user-defined-types)
- High performance: faster than common standard library
implementations of `(s)printf`, iostreams, `to_string` and
`to_chars`, see [Speed tests](#speed-tests) and [Converting a
hundred million integers to strings per
second](http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html)
- Small code size both in terms of source code with the minimum
configuration consisting of just three files, `core.h`, `format.h`
and `format-inl.h`, and compiled code; see [Compile time and code
bloat](#compile-time-and-code-bloat)
- Reliability: the library has an extensive set of
[tests](https://github.com/fmtlib/fmt/tree/master/test) and is
[continuously fuzzed](https://bugs.chromium.org/p/oss-fuzz/issues/list?colspec=ID%20Type%20Component%20Status%20Proj%20Reported%20Owner%20Summary&q=proj%3Dfmt&can=1)
- 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 MIT
[license](https://github.com/fmtlib/fmt/blob/master/LICENSE)
- [Portability](https://fmt.dev/latest/#portability) with
consistent output across platforms and support for older compilers
- Clean warning-free codebase even on high warning levels such as
`-Wall -Wextra -pedantic`
- Locale independence by default
- Optional header-only configuration enabled with the
`FMT_HEADER_ONLY` macro
See the [documentation](https://fmt.dev) for more details.
# Examples
**Print to stdout** ([run](https://godbolt.org/z/Tevcjh))
``` c++
#include <fmt/core.h>
int main() {
fmt::print("Hello, world!\n");
}
```
**Format a string** ([run](https://godbolt.org/z/oK8h33))
``` c++
std::string s = fmt::format("The answer is {}.", 42);
// s == "The answer is 42."
```
**Format a string using positional arguments**
([run](https://godbolt.org/z/Yn7Txe))
``` c++
std::string s = fmt::format("I'd rather be {1} than {0}.", "right", "happy");
// s == "I'd rather be happy than right."
```
**Print dates and times** ([run](https://godbolt.org/z/c31ExdY3W))
``` c++
#include <fmt/chrono.h>
int main() {
auto now = std::chrono::system_clock::now();
fmt::print("Date and time: {}\n", now);
fmt::print("Time: {:%H:%M}\n", now);
}
```
Output:
Date and time: 2023-12-26 19:10:31.557195597
Time: 19:10
**Print a container** ([run](https://godbolt.org/z/MxM1YqjE7))
``` c++
#include <vector>
#include <fmt/ranges.h>
int main() {
std::vector<int> v = {1, 2, 3};
fmt::print("{}\n", v);
}
```
Output:
[1, 2, 3]
**Check a format string at compile time**
``` c++
std::string s = fmt::format("{:d}", "I am not a number");
```
This gives a compile-time error in C++20 because `d` is an invalid
format specifier for a string.
**Write a file from a single thread**
``` c++
#include <fmt/os.h>
int main() {
auto out = fmt::output_file("guide.txt");
out.print("Don't {}", "Panic");
}
```
This can be [5 to 9 times faster than
fprintf](http://www.zverovich.net/2020/08/04/optimal-file-buffer-size.html).
**Print with colors and text styles**
``` c++
#include <fmt/color.h>
int main() {
fmt::print(fg(fmt::color::crimson) | fmt::emphasis::bold,
"Hello, {}!\n", "world");
fmt::print(fg(fmt::color::floral_white) | bg(fmt::color::slate_gray) |
fmt::emphasis::underline, "Olá, {}!\n", "Mundo");
fmt::print(fg(fmt::color::steel_blue) | fmt::emphasis::italic,
"你好{}！\n", "世界");
}
```
Output on a modern terminal with Unicode support:

# Benchmarks
## Speed tests
| Library | Method | Run Time, s |
|-------------------|---------------|-------------|
| libc | printf | 0.91 |
| libc++ | std::ostream | 2.49 |
| {fmt} 9.1 | fmt::print | 0.74 |
| Boost Format 1.80 | boost::format | 6.26 |
| Folly Format | folly::format | 1.87 |
{fmt} is the fastest of the benchmarked methods, \~20% faster than
`printf`.
The above results were generated by building `tinyformat_test.cpp` on
macOS 12.6.1 with `clang++ -O3 -DNDEBUG -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/src/tinyformat-test.cc).
{fmt} is up to 20-30x faster than `std::ostringstream` and `sprintf` on
IEEE754 `float` and `double` formatting
([dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark)) and faster
than [double-conversion](https://github.com/google/double-conversion)
and [ryu](https://github.com/ulfjack/ryu):
[![image](https://user-images.githubusercontent.com/576385/95684665-11719600-0ba8-11eb-8e5b-972ff4e49428.png)](https://fmt.dev/unknown_mac64_clang12.0.html)
## Compile time and code bloat
The script [bloat-test.py][test] from [format-benchmark][bench] tests compile
time and code bloat for nontrivial projects. It generates 100 translation units
and uses `printf()` or its alternative five times in each to simulate a
medium-sized project. The resulting executable size and compile time (Apple
clang version 15.0.0 (clang-1500.1.0.2.5), macOS Sonoma, best of three) is shown
in the following tables.
[test]: https://github.com/fmtlib/format-benchmark/blob/master/bloat-test.py
[bench]: https://github.com/fmtlib/format-benchmark
**Optimized build (-O3)**
| Method | Compile Time, s | Executable size, KiB | Stripped size, KiB |
|---------------|-----------------|----------------------|--------------------|
| printf | 1.6 | 54 | 50 |
| IOStreams | 25.9 | 98 | 84 |
| fmt 83652df | 4.8 | 54 | 50 |
| tinyformat | 29.1 | 161 | 136 |
| Boost Format | 55.0 | 530 | 317 |
{fmt} is fast to compile and is comparable to `printf` in terms of per-call
binary size (within a rounding error on this system).
**Non-optimized build**
| Method | Compile Time, s | Executable size, KiB | Stripped size, KiB |
|---------------|-----------------|----------------------|--------------------|
| printf | 1.4 | 54 | 50 |
| IOStreams | 23.4 | 92 | 68 |
| {fmt} 83652df | 4.4 | 89 | 85 |
| tinyformat | 24.5 | 204 | 161 |
| Boost Format | 36.4 | 831 | 462 |
`libc`, `lib(std)c++`, and `libfmt` are all linked as shared libraries
to compare formatting function overhead only. Boost Format is a
header-only library so it doesn\'t provide any linkage options.
## Running the tests
Please refer to [Building the
library](https://fmt.dev/latest/get-started/#building-from-source) for
instructions on how to build the library and run the unit tests.
Benchmarks reside in a separate repository,
[format-benchmarks](https://github.com/fmtlib/format-benchmark), so to
run the benchmarks you first need to clone this repository and generate
Makefiles with CMake:
$ git clone --recursive https://github.com/fmtlib/format-benchmark.git
$ cd format-benchmark
$ cmake .
Then you can run the speed test:
$ make speed-test
or the bloat test:
$ make bloat-test
# Migrating code
[clang-tidy](https://clang.llvm.org/extra/clang-tidy/) v18 provides the
[modernize-use-std-print](https://clang.llvm.org/extra/clang-tidy/checks/modernize/use-std-print.html)
check that is capable of converting occurrences of `printf` and
`fprintf` to `fmt::print` if configured to do so. (By default it
converts to `std::print`.)

# 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 and
FastFormat libraries. 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 somewhat mitigated with [\_\_attribute\_\_
((format (printf,
\...))](https://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:
``` c++
std::cout << std::setprecision(2) << std::fixed << 1.23456 << "\n";
```
which is a lot of typing compared to printf:
``` c++
printf("%.2f\n", 1.23456);
```
Matthew Wilson, the author of FastFormat, called this \"chevron hell\".
iostreams don\'t support positional arguments by design.
The good part is that iostreams support user-defined types and are safe
although error handling is awkward.
## Boost Format
This is a very powerful library that 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](#benchmarks)).
## FastFormat
This is an interesting library that 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, on STLSoft, which might be
too restrictive for use in some projects.
## Boost Spirit.Karma
This is not 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::format_to` with format string compilation
on Karma\'s own benchmark, see [Converting a hundred million integers to
strings per
second](http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html).

Features
--------
* Simple `format API <https://fmt.dev/latest/api.html>`_ with positional arguments
for localization
* Implementation of `C++20 std::format
<https://en.cppreference.com/w/cpp/utility/format>`__
* `Format string syntax <https://fmt.dev/latest/syntax.html>`_ similar to Python's
`format <https://docs.python.org/3/library/stdtypes.html#str.format>`_
* Fast IEEE 754 floating-point formatter with correct rounding, shortness and
round-trip guarantees using the `Dragonbox <https://github.com/jk-jeon/dragonbox>`_
algorithm
* Portable Unicode support
* Safe `printf implementation
<https://fmt.dev/latest/api.html#printf-formatting>`_ including the POSIX
extension for positional arguments
* Extensibility: `support for user-defined types
<https://fmt.dev/latest/api.html#formatting-user-defined-types>`_
* High performance: faster than common standard library implementations of
``(s)printf``, iostreams, ``to_string`` and ``to_chars``, see `Speed tests`_
and `Converting a hundred million integers to strings per second
<http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html>`_
* Small code size both in terms of source code with the minimum configuration
consisting of just three 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 `tests
<https://github.com/fmtlib/fmt/tree/master/test>`_ and is `continuously fuzzed
<https://bugs.chromium.org/p/oss-fuzz/issues/list?colspec=ID%20Type%20
Component%20Status%20Proj%20Reported%20Owner%20Summary&q=proj%3Dfmt&can=1>`_
* 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 MIT `license
<https://github.com/fmtlib/fmt/blob/master/LICENSE.rst>`_
* `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 such as
``-Wall -Wextra -pedantic``
* Locale independence by default
* Optional header-only configuration enabled with the ``FMT_HEADER_ONLY`` macro
See the `documentation <https://fmt.dev>`_ for more details.
Examples
--------
**Print to stdout** (`run <https://godbolt.org/z/Tevcjh>`_)
.. code:: c++
#include <fmt/core.h>
int main() {
fmt::print("Hello, world!\n");
}
**Format a string** (`run <https://godbolt.org/z/oK8h33>`_)
.. code:: c++
std::string s = fmt::format("The answer is {}.", 42);
// s == "The answer is 42."
**Format a string using positional arguments** (`run <https://godbolt.org/z/Yn7Txe>`_)
.. code:: c++
std::string s = fmt::format("I'd rather be {1} than {0}.", "right", "happy");
// s == "I'd rather be happy than right."
**Print chrono durations** (`run <https://godbolt.org/z/K8s4Mc>`_)
.. code:: c++
#include <fmt/chrono.h>
int main() {
using namespace std::literals::chrono_literals;
fmt::print("Default format: {} {}\n", 42s, 100ms);
fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s);
}
Output::
Default format: 42s 100ms
strftime-like format: 03:15:30
**Print a container** (`run <https://godbolt.org/z/MxM1YqjE7>`_)
.. code:: c++
#include <vector>
#include <fmt/ranges.h>
int main() {
std::vector<int> v = {1, 2, 3};
fmt::print("{}\n", v);
}
Output::
[1, 2, 3]
**Check a format string at compile time**
.. code:: c++
std::string s = fmt::format("{:d}", "I am not a number");
This gives a compile-time error in C++20 because ``d`` is an invalid format
specifier for a string.
**Write a file from a single thread**
.. code:: c++
#include <fmt/os.h>
int main() {
auto out = fmt::output_file("guide.txt");
out.print("Don't {}", "Panic");
}
This can be `5 to 9 times faster than fprintf
<http://www.zverovich.net/2020/08/04/optimal-file-buffer-size.html>`_.
**Print with colors and text styles**
.. code:: c++
#include <fmt/color.h>
int main() {
fmt::print(fg(fmt::color::crimson) | fmt::emphasis::bold,
"Hello, {}!\n", "world");
fmt::print(fg(fmt::color::floral_white) | bg(fmt::color::slate_gray) |
fmt::emphasis::underline, "Hello, {}!\n", "мир");
fmt::print(fg(fmt::color::steel_blue) | fmt::emphasis::italic,
"Hello, {}!\n", "世界");
}
Output on a modern terminal:

Benchmarks
----------
Speed tests
~~~~~~~~~~~
================= ============= ===========
Library Method Run Time, s
================= ============= ===========
libc printf 0.91
libc++ std::ostream 2.49
{fmt} 9.1 fmt::print 0.74
Boost Format 1.80 boost::format 6.26
Folly Format folly::format 1.87
================= ============= ===========
{fmt} is the fastest of the benchmarked methods, ~20% faster than ``printf``.
The above results were generated by building ``tinyformat_test.cpp`` on macOS
12.6.1 with ``clang++ -O3 -DNDEBUG -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/src/tinyformat-test.cc>`_.
{fmt} is up to 20-30x faster than ``std::ostringstream`` and ``sprintf`` on
IEEE754 ``float`` and ``double`` formatting (`dtoa-benchmark <https://github.com/fmtlib/dtoa-benchmark>`_)
and faster than `double-conversion <https://github.com/google/double-conversion>`_ and
`ryu <https://github.com/ulfjack/ryu>`_:
.. image:: https://user-images.githubusercontent.com/576385/
95684665-11719600-0ba8-11eb-8e5b-972ff4e49428.png
:target: https://fmt.dev/unknown_mac64_clang12.0.html
Compile time and code bloat
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The script `bloat-test.py
<https://github.com/fmtlib/format-benchmark/blob/master/bloat-test.py>`_
from `format-benchmark <https://github.com/fmtlib/format-benchmark>`_
tests compile time and code bloat for nontrivial projects.
It generates 100 translation units and uses ``printf()`` or its alternative
five times in each to simulate a medium-sized project. The resulting
executable size and compile time (Apple LLVM version 8.1.0 (clang-802.0.42),
macOS Sierra, best of three) is shown in the following tables.
**Optimized build (-O3)**
============= =============== ==================== ==================
Method Compile Time, s Executable size, KiB Stripped size, KiB
============= =============== ==================== ==================
printf 2.6 29 26
printf+string 16.4 29 26
iostreams 31.1 59 55
{fmt} 19.0 37 34
Boost Format 91.9 226 203
Folly Format 115.7 101 88
============= =============== ==================== ==================
As you can see, {fmt} has 60% less overhead in terms of resulting binary code
size compared to iostreams and comes pretty close to ``printf``. Boost Format
and Folly Format have the largest overheads.
``printf+string`` is the same as ``printf`` but with an extra ``<string>``
include to measure the overhead of the latter.
**Non-optimized build**
============= =============== ==================== ==================
Method Compile Time, s Executable size, KiB Stripped size, KiB
============= =============== ==================== ==================
printf 2.2 33 30
printf+string 16.0 33 30
iostreams 28.3 56 52
{fmt} 18.2 59 50
Boost Format 54.1 365 303
Folly Format 79.9 445 430
============= =============== ==================== ==================
``libc``, ``lib(std)c++``, and ``libfmt`` are all linked as shared libraries to
compare formatting function overhead only. Boost Format is a
header-only library so it doesn't provide any linkage options.

libraries. 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 somewhat mitigated with `__attribute__ ((format (printf, ...))
<https://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, called this "chevron hell". iostreams
don't support positional arguments by design.
The good part is that iostreams support user-defined types and are safe although
error handling is awkward.
Boost Format
~~~~~~~~~~~~
This is a very powerful library that 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 that 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.
Boost Spirit.Karma
~~~~~~~~~~~~~~~~~~
This is not 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::format_to`` with format string compilation on Karma's own benchmark,
see `Converting a hundred million integers to strings per second
<http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html>`_.
