10Description:
11This directory contains the source code of Abseil for C++. This can be used by
12Chromium, subject to the guidance at
13https://chromium.googlesource.com/chromium/src/+/main/styleguide/c++/c++-features.md;
14it can be used without restriction by Chromium's dependencies, except that
15objects compiled into Chromium itself cannot use anything relying on
16absl::base_internal::FastTypeId (see https://crbug.com/1096380).
17
18How to update Abseil:
19
201. Download the code from the Abseil git repository (see URL).
21
222. Copy the content of the Abseil git repo to //third_party/abseil-cpp.
23
243. From your source root run third_party/abseil-cpp/generate_def_files.py to
25   regenerate Windows symbol definition files.
26
27Local Modifications:
28
29* absl/copts.bzl has been translated to //third_party/absl-cpp/BUILD.gn. Both
30  files contain lists of compiler flags in order to reduce duplication.
31
32* All the BUILD.bazel files have been translated to BUILD.gn files.
33
34* Patches from //third_party/abseil-cpp/patches have been applied.
35
36* Increment this number to silence presubmits about modifying files in
37  third_party when regenerating absl .def files: 2

19## About Abseil
20
21Abseil is an open-source collection of C++ library code designed to augment
22the C++ standard library. The Abseil library code is collected from Google's
23own C++ code base, has been extensively tested and used in production, and
24is the same code we depend on in our daily coding lives.
25
26In some cases, Abseil provides pieces missing from the C++ standard; in
27others, Abseil provides alternatives to the standard for special needs
28we've found through usage in the Google code base. We denote those cases
29clearly within the library code we provide you.
30
31Abseil is not meant to be a competitor to the standard library; we've
32just found that many of these utilities serve a purpose within our code
33base, and we now want to provide those resources to the C++ community as
34a whole.

37## Quickstart
38
39If you want to just get started, make sure you at least run through the
40[Abseil Quickstart](https://abseil.io/docs/cpp/quickstart). The Quickstart
41contains information about setting up your development environment, downloading
42the Abseil code, running tests, and getting a simple binary working.
43
44<a name="build"></a>
45## Building Abseil
46
47[Bazel](https://bazel.build) and [CMake](https://cmake.org/) are the official
48build systems for Abseil.
49See the [quickstart](https://abseil.io/docs/cpp/quickstart) for more information
50on building Abseil using the Bazel build system.
51If you require CMake support, please check the [CMake build
52instructions](CMake/README.md) and [CMake
53Quickstart](https://abseil.io/docs/cpp/quickstart-cmake).

56## Support
57
58Abseil follows Google's [Foundational C++ Support
59Policy](https://opensource.google/documentation/policies/cplusplus-support). See
60[this
61table](https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md)
62for a list of currently supported versions compilers, platforms, and build
63tools.

66## Codemap
67
68Abseil contains the following C++ library components:
69
70* [`base`](absl/base/)
71  <br /> The `base` library contains initialization code and other code which
72  all other Abseil code depends on. Code within `base` may not depend on any
73  other code (other than the C++ standard library).
74* [`algorithm`](absl/algorithm/)
75  <br /> The `algorithm` library contains additions to the C++ `<algorithm>`
76  library and container-based versions of such algorithms.
77* [`cleanup`](absl/cleanup/)
78  <br /> The `cleanup` library contains the control-flow-construct-like type
79  `absl::Cleanup` which is used for executing a callback on scope exit.
80* [`container`](absl/container/)
81  <br /> The `container` library contains additional STL-style containers,
82  including Abseil's unordered "Swiss table" containers.
83* [`debugging`](absl/debugging/)
84  <br /> The `debugging` library contains code useful for enabling leak
85  checks, and stacktrace and symbolization utilities.
86* [`flags`](absl/flags/)
87  <br /> The `flags` library contains code for handling command line flags for
88  libraries and binaries built with Abseil.
89* [`hash`](absl/hash/)
90  <br /> The `hash` library contains the hashing framework and default hash
91  functor implementations for hashable types in Abseil.
92* [`iterator`](absl/iterator/)
93  <br /> The `iterator` library contains utilities for augmenting ranges in
94  range-based for loops.
95* [`log`](absl/log/)
96  <br /> The `log` library contains `LOG` and `CHECK` macros and facilities
97  for writing logged messages out to disk, `stderr`, or user-extensible
98  destinations.
99* [`memory`](absl/memory/)
100  <br /> The `memory` library contains memory management facilities that augment
101  C++'s `<memory>` library.
102* [`meta`](absl/meta/)
103  <br /> The `meta` library contains compatible versions of type checks
104  available within C++14 and C++17 versions of the C++ `<type_traits>` library.
105* [`numeric`](absl/numeric/)
106  <br /> The `numeric` library contains 128-bit integer types as well as
107  implementations of C++20's bitwise math functions.
108* [`profiling`](absl/profiling/)
109  <br /> The `profiling` library contains utility code for profiling C++
110  entities.  It is currently a private dependency of other Abseil libraries.
111* [`random`](absl/random/)
112  <br /> The `random` library contains functions for generating psuedorandom
113  values.
114* [`status`](absl/status/)
115  <br /> The `status` library contains abstractions for error handling,
116  specifically `absl::Status` and `absl::StatusOr<T>`.
117* [`strings`](absl/strings/)
118  <br /> The `strings` library contains a variety of strings routines and
119  utilities, including a C++14-compatible version of the C++17
120  `std::string_view` type.
121* [`synchronization`](absl/synchronization/)
122  <br /> The `synchronization` library contains concurrency primitives (Abseil's
123  `absl::Mutex` class, an alternative to `std::mutex`) and a variety of
124  synchronization abstractions.
125* [`time`](absl/time/)
126  <br /> The `time` library contains abstractions for computing with absolute
127  points in time, durations of time, and formatting and parsing time within
128  time zones.
129* [`types`](absl/types/)
130  <br /> The `types` library contains non-container utility types, like a
131  C++14-compatible version of the C++17 `std::optional` type.
132* [`utility`](absl/utility/)
133  <br /> The `utility` library contains utility and helper code.

136## Releases
137
138Abseil recommends users "live-at-head" (update to the latest commit from the
139master branch as often as possible). However, we realize this philosophy doesn't
140work for every project, so we also provide [Long Term Support
141Releases](https://github.com/abseil/abseil-cpp/releases) to which we backport
142fixes for severe bugs. See our [release
143management](https://abseil.io/about/releases) document for more details.
