Features
|
||||
--------
|
||||
|
||||
* Replacement-based `format API <https://fmt.dev/dev/api.html>`_ with
|
||||
positional arguments for localization.
|
||||
* `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.
|
||||
* 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.
|
||||
* Implementation of `C++20 std::format <https://fmt.dev/Text%20Formatting.html>`__.
|
||||
* Support for user-defined types.
|
||||
<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
|
||||
`printf <http://en.cppreference.com/w/cpp/io/c/fprintf>`_ and
|
||||
iostreams. See `Speed tests`_ and `Fast integer to string conversion in C++

Examples
|
||||
--------
|
||||
|
||||
Print ``Hello, world!`` to ``stdout``:
|
||||
**Print to stdout** (`run <https://godbolt.org/z/Tevcjh>`_)
|
||||
|
||||
.. code:: c++
|
||||
|
||||
fmt::print("Hello, {}!", "world"); // Python-like format string syntax
|
||||
fmt::printf("Hello, %s!", "world"); // printf format string syntax
|
||||
#include <fmt/core.h>
|
||||
|
||||
Format a string and use positional arguments:
|
||||
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."
|
||||
|
||||
Check a format string at compile time:
|
||||
**Print chrono durations** (`run <https://godbolt.org/z/K8s4Mc>`_)
|
||||
|
||||
.. code:: c++
|
||||
|
||||
// test.cc
|
||||
#include <fmt/format.h>
|
||||
std::string s = format(FMT_STRING("{2}"), 42);
|
||||
#include <fmt/chrono.h>
|
||||
|
||||
.. code::
|
||||
|
||||
$ c++ -Iinclude -std=c++14 test.cc
|
||||
...
|
||||
test.cc:4:17: note: in instantiation of function template specialization 'fmt::v5::format<S, int>' requested here
|
||||
std::string s = format(FMT_STRING("{2}"), 42);

|
||||

|

ErrorHandler::on_error(message);

|
||||
context_.on_error("argument index out of range");
|
||||
^
|
||||
|
||||
Use {fmt} as a safe portable replacement for ``itoa``
|
||||
(`godbolt <https://godbolt.org/g/NXmpU4>`_):
|
||||
|
||||
.. code:: c++
|
||||
|
||||
fmt::memory_buffer buf;
|
||||
format_to(buf, "{}", 42); // replaces itoa(42, buffer, 10)
|
||||
format_to(buf, "{:x}", 42); // replaces itoa(42, buffer, 16)
|
||||
// access the string with to_string(buf) or buf.data()
|
||||
|
||||
Format objects of user-defined types via a simple `extension API
|
||||
<https://fmt.dev/latest/api.html#formatting-user-defined-types>`_:
|
||||
|
||||
.. code:: c++
|
||||
|
||||
#include "fmt/format.h"
|
||||
|
||||
struct date {
|
||||
int year, month, day;
|
||||
};
|
||||
|
||||
template <>
|
||||
struct fmt::formatter<date> {
|
||||
constexpr auto parse(format_parse_context& ctx) { return ctx.begin(); }
|
||||
|
||||
template <typename FormatContext>
|
||||
auto format(const date& d, FormatContext& ctx) {
|
||||
return format_to(ctx.out(), "{}-{}-{}", d.year, d.month, d.day);
|
||||
}
|
||||
};
|
||||
|
||||
std::string s = fmt::format("The date is {}", date{2012, 12, 9});
|
||||
// s == "The date is 2012-12-9"
|
||||
|
||||
Create your own functions similar to `format
|
||||
<https://fmt.dev/latest/api.html#format>`_ and
|
||||
`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) {
|
||||
fmt::print("Error: ");
|
||||
fmt::vprint(format, args);
|
||||
}
|
||||
template <typename... Args>
|
||||
void report_error(const char* format, const Args & ... args) {
|
||||
vreport_error(format, fmt::make_format_args(args...));
|
||||
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);
|
||||
}
|
||||
|
||||
report_error("file not found: {}", path);
|
||||
Output::
|
||||
|
||||
Note that ``vreport_error`` is not parameterized on argument types which can
|
||||
improve compile times and reduce code size compared to a fully parameterized
|
||||
version.
|
||||
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) |

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_int`` on Karma's own benchmark,

||||

Q: how can I capture formatting arguments and format them later?
|
||||
|
||||
A: use ``std::tuple``:
|
||||
|
||||
.. code:: c++
|
||||
|
||||
template <typename... Args>
|
||||
auto capture(const Args&... args) {
|
||||
return std::make_tuple(args...);
|
||||
}
|
||||
|
||||
auto print_message = [](const auto&... args) {
|
||||
fmt::print(args...);
|
||||
};
|
||||
|
||||
// Capture and store arguments:
|
||||
auto args = capture("{} {}", 42, "foo");
|
||||
// Do formatting:
|
||||
std::apply(print_message, args);
|
||||
than ``fmt::format_to`` with format string compilation on Karma's own benchmark,
|
||||
see `Converting a hundred million integers to strings per second

A reference to a null-terminated string. It can be constructed from a C
