# 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) and
[C++23 std::print](https://en.cppreference.com/w/cpp/io/print)
- [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](#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

# 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](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.
## Running the tests
Please refer to [Building the
library](https://fmt.dev/latest/usage.html#building-the-library) 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/) v17 (not yet
released) 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, 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).

\rst
A ``printf`` argument formatter based on the `curiously recurring template

To use `~fmt::BasicPrintfArgFormatter` define a subclass that implements some
or all of the visit methods with the same signatures as the methods in
`~fmt::ArgVisitor`, for example, `~fmt::ArgVisitor::visit_int()`.
Pass the subclass as the *Impl* template parameter. When a formatting
function processes an argument, it will dispatch to a visit method
specific to the argument type. For example, if the argument type is
``double`` then the `~fmt::ArgVisitor::visit_double()` method of a subclass
will be called. If the subclass doesn't contain a method with this signature,
then a corresponding method of `~fmt::BasicPrintfArgFormatter` or its
superclass will be called.

# Bazel support
To get [Bazel](https://bazel.build/) working with {fmt} you can copy the files `BUILD.bazel`, `WORKSPACE.bazel`, and `.bazelversion` from this folder (`support/bazel`) to the root folder of this project. This way {fmt} gets bazelized and can be used with Bazel (e.g. doing a `bazel build //...` on {fmt}).
## Using {fmt} as a dependency
The following minimal example shows how to use {fmt} as a dependency within a Bazel project.
The following file structure is assumed:
```
example
├── BUILD.bazel
├── main.cpp
└── WORKSPACE.bazel
```
*main.cpp*:
```c++
#include "fmt/core.h"
int main() {
fmt::print("The answer is {}\n", 42);
}
```
The expected output of this example is `The answer is 42`.
*WORKSPACE.bazel*:
```python
load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")
git_repository(
name = "fmt",
branch = "master",
remote = "https://github.com/fmtlib/fmt",
patch_cmds = [
"mv support/bazel/.bazelversion .bazelversion",
"mv support/bazel/BUILD.bazel BUILD.bazel",
"mv support/bazel/WORKSPACE.bazel WORKSPACE.bazel",
],
# Windows-related patch commands are only needed in the case MSYS2 is not installed.
# More details about the installation process of MSYS2 on Windows systems can be found here:
# https://docs.bazel.build/versions/main/install-windows.html#installing-compilers-and-language-runtimes
# Even if MSYS2 is installed the Windows related patch commands can still be used.
patch_cmds_win = [
"Move-Item -Path support/bazel/.bazelversion -Destination .bazelversion",
"Move-Item -Path support/bazel/BUILD.bazel -Destination BUILD.bazel",
"Move-Item -Path support/bazel/WORKSPACE.bazel -Destination WORKSPACE.bazel",
],
)
```
In the *WORKSPACE* file, the {fmt} GitHub repository is fetched. Using the attribute `patch_cmds` the files `BUILD.bazel`, `WORKSPACE.bazel`, and `.bazelversion` are moved to the root of the {fmt} repository. This way the {fmt} repository is recognized as a bazelized workspace.
*BUILD.bazel*:
```python
cc_binary(
name = "Demo",
srcs = ["main.cpp"],
deps = ["@fmt"],
)
```
The *BUILD* file defines a binary named `Demo` that has a dependency to {fmt}.
To execute the binary you can run `bazel run //:Demo`.
# Using Bzlmod
The [Bazel Central Registry](https://github.com/bazelbuild/bazel-central-registry/tree/main/modules/fmt) also provides support for {fmt}.

`docopt` creates your command-line interface based on its
description that you pass as `doc`. Such description can contain
--options, <positional-argument>, commands, which could be
[optional], (required), (mutually | exclusive) or repeated...
Parameters
----------
doc : str
Description of your command-line interface.
argv : list of str, optional
Argument vector to be parsed. sys.argv[1:] is used if not
provided.
help : bool (default: True)
Set to False to disable automatic help on -h or --help
options.
version : any object
If passed, the object will be printed if --version is in
`argv`.
options_first : bool (default: False)
Set to True to require options precede positional arguments,
i.e. to forbid options and positional arguments intermix.
Returns
-------
args : dict
A dictionary, where keys are names of command-line elements
such as e.g. "--verbose" and "<path>", and values are the
parsed values of those elements.
Example
-------
>>> from docopt import docopt
>>> doc = '''
... Usage:
... my_program tcp <host> <port> [--timeout=<seconds>]
... my_program serial <port> [--baud=<n>] [--timeout=<seconds>]
... my_program (-h | --help | --version)
...
... Options:
... -h, --help Show this screen and exit.
... --baud=<n> Baudrate [default: 9600]
... '''
>>> argv = ['tcp', '127.0.0.1', '80', '--timeout', '30']
>>> docopt(doc, argv)
