Q&A: ask questions on `StackOverflow with the tag fmt
|
||||
<https://stackoverflow.com/questions/tagged/fmt>`_.
|
||||
|
||||

|
||||
|
||||
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.
|
||||
* 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%3Dlibfmt&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/MjsY7c>`_)
|
||||
|
||||
.. 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(FMT_STRING("{:d}"), "don't panic");
|
||||
|
||||
This gives a compile-time error 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");
|
||||
}
|
||||
|
||||

Benchmarks
|
||||
----------
|
||||
|
||||
Speed tests
|
||||
~~~~~~~~~~~
|
||||
|
||||
================= ============= ===========
|
||||
Library Method Run Time, s
|
||||
================= ============= ===========
|
||||
libc printf 1.04
|
||||
libc++ std::ostream 3.05
|
||||
{fmt} 6.1.1 fmt::print 0.75
|
||||
Boost Format 1.67 boost::format 7.24
|
||||
Folly Format folly::format 2.23
|
||||
================= ============= ===========
|
||||
|
||||
{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 -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/tinyformat_test.cpp>`_.
|
||||
|
||||
{fmt} is up to 10x faster than ``std::ostringstream`` and ``sprintf`` on
|
||||
floating-point formatting (`dtoa-benchmark <https://github.com/fmtlib/dtoa-benchmark>`_)
|
||||
and faster than `double-conversion <https://github.com/google/double-conversion>`_:
|
||||

|
||||
|
||||
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 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.
|
||||
|
||||
Running the tests
|
||||
~~~~~~~~~~~~~~~~~
|
||||
|
||||
Please refer to `Building the library`__ for the instructions on how to build
|
||||
the library and run the unit tests.
|
||||
|
||||
__ https://fmt.dev/latest/usage.html#building-the-library
|
||||
|
||||
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
|
||||

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:
|
||||
|
||||
.. 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 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.
|
||||
|
||||
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::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>`_.
