# Issue
Please describe the issue you are seeing with OSRM.
Images are a good way to illustrate your problem.
**Note**: If your issue relates to the demo site (https://map.project-osrm.org) or routing provided on openstreetmap.org, be aware that they use separate [profile settings](https://github.com/fossgis-routing-server/cbf-routing-profiles) from those provided by default in `osrm-backend`.
If your issue relates to the demo site or openstreetmap.org behaviour, please check these profiles first to see if they explain the behaviour before creating an issue here.
# Steps to reproduce
Please provide the steps required to reproduce your problem.
- `osrm-backend` version being used
- OSM extract that was processed
- Processing commands (e.g. CH vs MLD processing)
- Server queries
If you're reporting an issue with https://map.project-osrm.org, please provide a link to the problematic request.
# Specifications
Please provide details of your development environment.
- Library/dependency versions
- Operating system
- Hardware

# Releasing
Releasing a new version of `node-osrm` is mostly automated using Travis CI.
The version of `node-osrm` is locked to the same version as `osrm-backend`. Every `node-osrm` should have a `osrm-backend` release of the same version. Of course, only release a `node-osrm` after the release has been tagged in `osrm-backend`.
These steps all happen on `master`. After the release is out, create a branch using the MAJOR.MINOR version of the release to document code changes made for that version.
### Steps to release
1. Update the `osrm_release` field in `package.json` to the corresonding git tag in `osrm-backend.`
Confirm the desired OSRM branch and commit to `master`.
1. Bump node-osrm version
Update the `CHANGELOG.md` and the `package.json` version if needed.
1. Check that Travis CI [builds are passing](https://travis-ci.org/Project-OSRM/node-osrm) for the latest commit on `master`.
1. Publishing binaries
If travis builds are passing then it's time to publish binaries by committing with a message containing `[publish binary]`. Use an empty commit for this.
```
git commit --allow-empty -m "[publish binary] vMAJOR.MINOR.PATCH"
```
1. Test
Locally you can now test binaries. Cleanup, re-install, and run the tests like:
```
make clean
npm install # will pull remote binaries
npm ls # confirm deps are correct
make test
```
1. Tag
Once binaries are published for Linux and OS X then its time to tag a new release and add the changelog to the tag:
```
git tag vMAJOR.MINOR.PATCH -a
git push --tags
```
1. Publish node-osrm. **we only do this for stable releases**
First ensure your local `node-pre-gyp` is up to date:
```
npm ls
```
This is important because it is bundled during packaging.
If you see any errors then do:
```
rm -rf node_modules/node-pre-gyp
npm install node-pre-gyp
```
Now we're ready to publish `node-osrm` to <https://www.npmjs.org/package/osrm>:
```
npm publish
```
Dependent apps can now pull from the npm registry like:
```
"dependencies": {
"osrm": "^MAJOR.MINOR.PATCH"
}
```
Or can still pull from the github tag like:
```
"dependencies": {
"osrm": "https://github.com/Project-OSRM/node-osrm/archive/vMAJOR.MINOR.PATCH.tar.gz"
}
```

# Building OSRM for Windows
There is experimental support for building OSRM on Windows.
## Dependencies
Get a decent Windows with decent Visual Studio (14 at least for C++11 support). The published binaries are build with
VS2019 and Windows SDK8.1.
You will need a modern Windows development stack (e.g. Visual Studio 17). The published binaries are built with
[Windows Server 2022](https://github.com/actions/runner-images/blob/main/images/win/Windows2022-Readme.md) Github hosted runners.
In case you are using [prepacked Windows VM with VS2019](https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/), you
have to install [Windows SDK 8.1](https://go.microsoft.com/fwlink/p/?LinkId=323507)
Dependencies are managed via [Conan](https://conan.io/) and built with [CMake](https://cmake.org/).
Prepare directories for dependencies, build and target file location.Target directory ($target starting from that moment) should have /include and /lib subdirectories.
## Building
### Bzip2

**{fmt}** is an open-source formatting library providing a fast and safe
alternative to C stdio and C++ iostreams.
If you like this project, please consider donating to one of the funds that
help victims of the war in Ukraine: https://www.stopputin.net/.
`Documentation <https://fmt.dev>`__
`Cheat Sheets <https://hackingcpp.com/cpp/libs/fmt.html>`__
Q&A: ask questions on `StackOverflow with the tag fmt
<https://stackoverflow.com/questions/tagged/fmt>`_.
Try {fmt} in `Compiler Explorer <https://godbolt.org/z/Eq5763>`_.
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%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 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/src/tinyformat-test.cc>`_.
{fmt} is up to 20-30x 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>`_ and
`ryu <https://github.com/ulfjack/ryu>`_:
.. image:: https://user-images.githubusercontent.com/576385/

: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 extra ``<string>``
include to measure the overhead of the latter.
**Non-optimized build**
============= =============== ==================== ==================

``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
Migrating code
--------------
`clang-tidy-fmt <https://github.com/mikecrowe/clang-tidy-fmt>`_ provides clang
tidy checks for converting occurrences of ``printf`` and ``fprintf`` to
``fmt::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:
.. 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>`_.

API Reference
*************
The {fmt} library API consists of the following parts:
* :ref:`fmt/core.h <core-api>`: the core API providing main formatting functions
for ``char``/UTF-8 with C++20 compile-time checks and minimal dependencies
* :ref:`fmt/format.h <format-api>`: the full format API providing additional
formatting functions and locale support
* :ref:`fmt/ranges.h <ranges-api>`: formatting of ranges and tuples
* :ref:`fmt/chrono.h <chrono-api>`: date and time formatting
* :ref:`fmt/std.h <std-api>`: formatters for standard library types
* :ref:`fmt/compile.h <compile-api>`: format string compilation
* :ref:`fmt/color.h <color-api>`: terminal color and text style
* :ref:`fmt/os.h <os-api>`: system APIs
* :ref:`fmt/ostream.h <ostream-api>`: ``std::ostream`` support
* :ref:`fmt/printf.h <printf-api>`: ``printf`` formatting
* :ref:`fmt/xchar.h <xchar-api>`: optional ``wchar_t`` support
All functions and types provided by the library reside in namespace ``fmt`` and
macros have prefix ``FMT_``.
.. _core-api:
Core API
========
``fmt/core.h`` defines the core API which provides main formatting functions
for ``char``/UTF-8 with C++20 compile-time checks. It has minimal include
dependencies for better compile times. This header is only beneficial when
using {fmt} as a library and not in the header-only mode.
The following functions use :ref:`format string syntax <syntax>`
similar to that of Python's `str.format
<https://docs.python.org/3/library/stdtypes.html#str.format>`_.
They take *fmt* and *args* as arguments.
*fmt* is a format string that contains literal text and replacement fields
surrounded by braces ``{}``. The fields are replaced with formatted arguments
in the resulting string. `~fmt::format_string` is a format string which can be
implicitly constructed from a string literal or a ``constexpr`` string and is
checked at compile time in C++20. To pass a runtime format string wrap it in
`fmt::runtime`.
*args* is an argument list representing objects to be formatted.
.. _format:
.. doxygenfunction:: format(format_string<T...> fmt, T&&... args) -> std::string
.. doxygenfunction:: vformat(string_view fmt, format_args args) -> std::string
.. doxygenfunction:: format_to(OutputIt out, format_string<T...> fmt, T&&... args) -> OutputIt
.. doxygenfunction:: format_to_n(OutputIt out, size_t n, format_string<T...> fmt, T&&... args) -> format_to_n_result<OutputIt>
.. doxygenfunction:: formatted_size(format_string<T...> fmt, T&&... args) -> size_t
.. doxygenstruct:: fmt::format_to_n_result
:members:
.. _print:
.. doxygenfunction:: fmt::print(format_string<T...> fmt, T&&... args)
.. doxygenfunction:: fmt::vprint(string_view fmt, format_args args)
.. doxygenfunction:: print(std::FILE *f, format_string<T...> fmt, T&&... args)
.. doxygenfunction:: vprint(std::FILE *f, string_view fmt, format_args args)
Compile-Time Format String Checks
---------------------------------
Compile-time checks are enabled by default on compilers that support C++20
``consteval``. On older compilers you can use the ``FMT_STRING`` macro defined
in ``fmt/format.h`` instead. It requires C++14 and is a no-op in C++11.
.. doxygendefine:: FMT_STRING
To force the use of legacy compile-time checks, define the preprocessor variable
``FMT_ENFORCE_COMPILE_STRING``. When set, functions accepting ``FMT_STRING``
will fail to compile with regular strings. Runtime-checked formatting is still
possible using ``fmt::vformat``, ``fmt::vprint``, etc.
.. doxygenclass:: fmt::basic_format_string
:members:
.. doxygentypedef:: fmt::format_string
.. doxygenfunction:: fmt::runtime(string_view) -> basic_runtime<char>
Named Arguments
---------------
.. doxygenfunction:: fmt::arg(const S&, const T&)
Named arguments are not supported in compile-time checks at the moment.
Argument Lists
--------------
You can create your own formatting function with compile-time checks and small
binary footprint, for example (https://godbolt.org/z/oba4Mc):
.. code:: c++
#include <fmt/format.h>
void vlog(const char* file, int line, fmt::string_view format,
fmt::format_args args) {
fmt::print("{}: {}: ", file, line);
fmt::vprint(format, args);
}
template <typename S, typename... Args>
void log(const char* file, int line, const S& format, Args&&... args) {
vlog(file, line, format, fmt::make_format_args(args...));
}
#define MY_LOG(format, ...) \
log(__FILE__, __LINE__, FMT_STRING(format), __VA_ARGS__)
MY_LOG("invalid squishiness: {}", 42);
Note that ``vlog`` is not parameterized on argument types which improves compile
times and reduces binary code size compared to a fully parameterized version.
.. doxygenfunction:: fmt::make_format_args(const Args&...)
.. doxygenclass:: fmt::format_arg_store

.. doxygenclass:: fmt::dynamic_format_arg_store

.. doxygenclass:: fmt::basic_format_args

Compatibility
-------------
.. doxygenclass:: fmt::basic_string_view
:members:
.. doxygentypedef:: fmt::string_view
Locale
------
All formatting is locale-independent by default. Use the ``'L'`` format
specifier to insert the appropriate number separator characters from the
locale::
#include <fmt/core.h>
#include <locale>
std::locale::global(std::locale("en_US.UTF-8"));
auto s = fmt::format("{:L}", 1000000); // s == "1,000,000"
.. _format-api:
Format API
==========
``fmt/format.h`` defines the full format API providing additional formatting
functions and locale support.
.. _udt:
Formatting User-Defined Types
-----------------------------
The {fmt} library provides formatters for many standard C++ types.
See :ref:`fmt/ranges.h <ranges-api>` for ranges and tuples including standard
containers such as ``std::vector``, :ref:`fmt/chrono.h <chrono-api>` for date
and time formatting and :ref:`fmt/std.h <std-api>` for path and variant
formatting.
To make a user-defined type formattable, specialize the ``formatter<T>`` struct
template and implement ``parse`` and ``format`` methods::
#include <fmt/format.h>
struct point {
double x, y;
};
template <> struct fmt::formatter<point> {
// Presentation format: 'f' - fixed, 'e' - exponential.
char presentation = 'f';
// Parses format specifications of the form ['f' | 'e'].
constexpr auto parse(format_parse_context& ctx) -> decltype(ctx.begin()) {
// [ctx.begin(), ctx.end()) is a character range that contains a part of
// the format string starting from the format specifications to be parsed,
// e.g. in
//
// fmt::format("{:f} - point of interest", point{1, 2});
//
// the range will contain "f} - point of interest". The formatter should
// parse specifiers until '}' or the end of the range. In this example
// the formatter should parse the 'f' specifier and return an iterator
// pointing to '}'.
// Please also note that this character range may be empty, in case of
// the "{}" format string, so therefore you should check ctx.begin()
// for equality with ctx.end().
// Parse the presentation format and store it in the formatter:
auto it = ctx.begin(), end = ctx.end();
if (it != end && (*it == 'f' || *it == 'e')) presentation = *it++;
// Check if reached the end of the range:
if (it != end && *it != '}') throw format_error("invalid format");
// Return an iterator past the end of the parsed range:
return it;
}
// Formats the point p using the parsed format specification (presentation)
// stored in this formatter.
template <typename FormatContext>
auto format(const point& p, FormatContext& ctx) const -> decltype(ctx.out()) {
// ctx.out() is an output iterator to write to.
return presentation == 'f'
? fmt::format_to(ctx.out(), "({:.1f}, {:.1f})", p.x, p.y)
: fmt::format_to(ctx.out(), "({:.1e}, {:.1e})", p.x, p.y);
}
};
Then you can pass objects of type ``point`` to any formatting function::
point p = {1, 2};
std::string s = fmt::format("{:f}", p);
// s == "(1.0, 2.0)"
You can also reuse existing formatters via inheritance or composition, for
example::
enum class color {red, green, blue};
template <> struct fmt::formatter<color>: formatter<string_view> {
// parse is inherited from formatter<string_view>.
template <typename FormatContext>
auto format(color c, FormatContext& ctx) const {
string_view name = "unknown";
switch (c) {
case color::red: name = "red"; break;
case color::green: name = "green"; break;
case color::blue: name = "blue"; break;
}
return formatter<string_view>::format(name, ctx);
}
};
Since ``parse`` is inherited from ``formatter<string_view>`` it will recognize
all string format specifications, for example
.. code-block:: c++
fmt::format("{:>10}", color::blue)
will return ``" blue"``.
You can also write a formatter for a hierarchy of classes::
#include <type_traits>
#include <fmt/format.h>
struct A {
virtual ~A() {}
virtual std::string name() const { return "A"; }
};
struct B : A {
virtual std::string name() const { return "B"; }
};
template <typename T>
struct fmt::formatter<T, std::enable_if_t<std::is_base_of<A, T>::value, char>> :
fmt::formatter<std::string> {
template <typename FormatCtx>
auto format(const A& a, FormatCtx& ctx) const {
return fmt::formatter<std::string>::format(a.name(), ctx);
}
};
int main() {
B b;
A& a = b;
fmt::print("{}", a); // prints "B"
}
If a type provides both a ``formatter`` specialization and an implicit
conversion to a formattable type, the specialization takes precedence over the
conversion.
For enums {fmt} also provides the ``format_as`` extension API. To format an enum
via this API define ``format_as`` that takes this enum and converts it to the
underlying type. ``format_as`` should be defined in the same namespace as the
enum.
Example (https://godbolt.org/z/r7vvGE1v7)::
#include <fmt/format.h>
namespace kevin_namespacy {
enum class film {
house_of_cards, american_beauty, se7en = 7
};
auto format_as(film f) { return fmt::underlying(f); }
}
int main() {
fmt::print("{}\n", kevin_namespacy::film::se7en); // prints "7"
}
Literal-Based API
-----------------
The following user-defined literals are defined in ``fmt/format.h``.
.. doxygenfunction:: operator""_a()
Utilities
---------
.. doxygenfunction:: fmt::ptr(T p) -> const void*
.. doxygenfunction:: fmt::ptr(const std::unique_ptr<T> &p) -> const void*
.. doxygenfunction:: fmt::ptr(const std::shared_ptr<T> &p) -> const void*
.. doxygenfunction:: fmt::underlying(Enum e) -> typename std::underlying_type<Enum>::type
.. doxygenfunction:: fmt::to_string(const T &value) -> std::string
.. doxygenfunction:: fmt::join(Range &&range, string_view sep) -> join_view<detail::iterator_t<Range>, detail::sentinel_t<Range>>
.. doxygenfunction:: fmt::join(It begin, Sentinel end, string_view sep) -> join_view<It, Sentinel>
.. doxygenfunction:: fmt::group_digits(T value) -> group_digits_view<T>
.. doxygenclass:: fmt::detail::buffer
:members:
.. doxygenclass:: fmt::basic_memory_buffer
:protected-members:
:members:
System Errors
-------------
{fmt} does not use ``errno`` to communicate errors to the user, but it may call
system functions which set ``errno``. Users should not make any assumptions
about the value of ``errno`` being preserved by library functions.
.. doxygenfunction:: fmt::system_error
.. doxygenfunction:: fmt::format_system_error
Custom Allocators
-----------------
The {fmt} library supports custom dynamic memory allocators.
A custom allocator class can be specified as a template argument to
:class:`fmt::basic_memory_buffer`::
using custom_memory_buffer =
fmt::basic_memory_buffer<char, fmt::inline_buffer_size, custom_allocator>;
It is also possible to write a formatting function that uses a custom
allocator::
using custom_string =
std::basic_string<char, std::char_traits<char>, custom_allocator>;
custom_string vformat(custom_allocator alloc, fmt::string_view format_str,
fmt::format_args args) {
auto buf = custom_memory_buffer(alloc);
fmt::vformat_to(std::back_inserter(buf), format_str, args);
return custom_string(buf.data(), buf.size(), alloc);
}
template <typename ...Args>
inline custom_string format(custom_allocator alloc,
fmt::string_view format_str,
const Args& ... args) {
return vformat(alloc, format_str, fmt::make_format_args(args...));
}
The allocator will be used for the output container only. Formatting functions
normally don't do any allocations for built-in and string types except for
non-default floating-point formatting that occasionally falls back on
``sprintf``.
.. _ranges-api:
Range and Tuple Formatting
==========================
The library also supports convenient formatting of ranges and tuples::
#include <fmt/ranges.h>
std::tuple<char, int, float> t{'a', 1, 2.0f};
// Prints "('a', 1, 2.0)"
fmt::print("{}", t);
NOTE: currently, the overload of ``fmt::join`` for iterables exists in the main
``format.h`` header, but expect this to change in the future.
Using ``fmt::join``, you can separate tuple elements with a custom separator::
#include <fmt/ranges.h>
std::tuple<int, char> t = {1, 'a'};
// Prints "1, a"
fmt::print("{}", fmt::join(t, ", "));
.. _chrono-api:
Date and Time Formatting
========================
``fmt/chrono.h`` provides formatters for
* `std::chrono::duration <https://en.cppreference.com/w/cpp/chrono/duration>`_
* `std::chrono::time_point
<https://en.cppreference.com/w/cpp/chrono/time_point>`_
* `std::tm <https://en.cppreference.com/w/cpp/chrono/c/tm>`_
The format syntax is described in :ref:`chrono-specs`.
**Example**::
#include <fmt/chrono.h>
int main() {
std::time_t t = std::time(nullptr);
// Prints "The date is 2020-11-07." (with the current date):
fmt::print("The date is {:%Y-%m-%d}.", fmt::localtime(t));
using namespace std::literals::chrono_literals;
// Prints "Default format: 42s 100ms":
fmt::print("Default format: {} {}\n", 42s, 100ms);
// Prints "strftime-like format: 03:15:30":
fmt::print("strftime-like format: {:%H:%M:%S}\n", 3h + 15min + 30s);
}
.. doxygenfunction:: localtime(std::time_t time)
.. doxygenfunction:: gmtime(std::time_t time)
.. _std-api:
Standard Library Types Formatting
=================================
``fmt/std.h`` provides formatters for:
* `std::filesystem::path <https://en.cppreference.com/w/cpp/filesystem/path>`_
* `std::thread::id <https://en.cppreference.com/w/cpp/thread/thread/id>`_
* `std::monostate <https://en.cppreference.com/w/cpp/utility/variant/monostate>`_
* `std::variant <https://en.cppreference.com/w/cpp/utility/variant/variant>`_
Formatting Variants
-------------------
A ``std::variant`` is only formattable if every variant alternative is formattable, and requires the
``__cpp_lib_variant`` `library feature <https://en.cppreference.com/w/cpp/feature_test>`_.
**Example**::
#include <fmt/std.h>
std::variant<char, float> v0{'x'};
// Prints "variant('x')"
fmt::print("{}", v0);
std::variant<std::monostate, char> v1;
// Prints "variant(monostate)"
.. _compile-api:
Format String Compilation
=========================
``fmt/compile.h`` provides format string compilation enabled via the
``FMT_COMPILE`` macro or the ``_cf`` user-defined literal. Format strings
marked with ``FMT_COMPILE`` or ``_cf`` are parsed, checked and converted into
efficient formatting code at compile-time. This supports arguments of built-in
and string types as well as user-defined types with ``constexpr`` ``parse``
functions in their ``formatter`` specializations. Format string compilation can
generate more binary code compared to the default API and is only recommended in
places where formatting is a performance bottleneck.
.. doxygendefine:: FMT_COMPILE
.. doxygenfunction:: operator""_cf()
.. _color-api:
Terminal Color and Text Style
=============================
``fmt/color.h`` provides support for terminal color and text style output.

``std::ostream`` Support
========================
``fmt/ostream.h`` provides ``std::ostream`` support including formatting of
user-defined types that have an overloaded insertion operator (``operator<<``).
In order to make a type formattable via ``std::ostream`` you should provide a
``formatter`` specialization inherited from ``ostream_formatter``::
#include <fmt/ostream.h>
struct date {
int year, month, day;
friend std::ostream& operator<<(std::ostream& os, const date& d) {
return os << d.year << '-' << d.month << '-' << d.day;
}
};
template <> struct fmt::formatter<date> : ostream_formatter {};
std::string s = fmt::format("The date is {}", date{2012, 12, 9});
// s == "The date is 2012-12-9"
.. doxygenfunction:: streamed(const T &)
.. doxygenfunction:: print(std::ostream &os, format_string<T...> fmt, T&&... args)
.. _printf-api:
``printf`` Formatting
=====================
The header ``fmt/printf.h`` provides ``printf``-like formatting functionality.
The following functions use `printf format string syntax
<https://pubs.opengroup.org/onlinepubs/009695399/functions/fprintf.html>`_ with
the POSIX extension for positional arguments. Unlike their standard
counterparts, the ``fmt`` functions are type-safe and throw an exception if an
argument type doesn't match its format specification.
.. doxygenfunction:: printf(const S &format_str, const T&... args)
.. doxygenfunction:: fprintf(std::FILE *f, const S &fmt, const T&... args) -> int
.. doxygenfunction:: sprintf(const S&, const T&...)
.. _xchar-api:
``wchar_t`` Support
===================
The optional header ``fmt/xchar.h`` provides support for ``wchar_t`` and exotic
character types.
.. doxygenstruct:: fmt::is_char
.. doxygentypedef:: fmt::wstring_view
.. doxygentypedef:: fmt::wformat_context
.. doxygenfunction:: fmt::to_wstring(const T &value)
Compatibility with C++20 ``std::format``
========================================
{fmt} implements nearly all of the `C++20 formatting library
<https://en.cppreference.com/w/cpp/utility/format>`_ with the following
differences:
* Names are defined in the ``fmt`` namespace instead of ``std`` to avoid
collisions with standard library implementations.
* Width calculation doesn't use grapheme clusterization. The latter has been
implemented in a separate branch but hasn't been integrated yet.
* Most C++20 chrono types are not supported yet.

// This way, we ensure a DOM element is visible to position the popover from.
