Its distinguishing design is that flag definitions can live in the source file that uses them, with the library collecting, parsing, validating, and documenting those flags for an executable. ### プロジェクトの歴史 The changelog records a Google Inc. 0.1 release in December 2006, followed by 1.0 in October 2008 and several google-gflags releases through 2011. In January 2012, the project was renamed from google-gflags to gflags as Google stepped back from ownership and Andreas Schuh became maintainer. ### 採用の歴史 gflags spread through C++ infrastructure because it offered a Google-style alternative to getopt-like parsers: each library or translation unit could declare its own flags, while users still received unified help output and parsing behavior. Later releases emphasized package and build-system integration, including CMake, Bazel, pkg-config, Homebrew, Debian/Ubuntu packages, and vcpkg. ### 使われ方 Practitioners add `DEFINE_*` and `DECLARE_*` macros in C++ code, link the library, call the parser during program startup, and then read `FLAGS_name` variables from the relevant code. The installation docs cover use through distro packages, Homebrew, Bazel, vcpkg, and CMake. ### パッケージ好きにとっての重要性 gflags matters to package maintainers because it is both a runtime library and a build-system integration target for many C++ projects. The long namespace transition from `google` to `gflags`, plus compatibility for projects such as glog, made ABI and include-path behavior unusually important. ### タイムライン - 2006: Google Inc. released google-gflags 0.1. - 2008: google-gflags 1.0 was released. - 2012: google-gflags was renamed to gflags and community ownership began. - 2014: Version 2.1 switched the build configuration to CMake and changed the default namespace to `gflags`. - 2015: Version 2.1.2 completed the move from Google Code to GitHub. - 2025: Version 2.3.0 added maintenance fixes for Bazel, CMake, QNX, and option processing. ### Related projects - The README points Abseil users to Abseil Flags, noting that an internal fork of the library was re-released as part of Abseil. The gflags organization also includes python-gflags history, which moved to Google's Python repository and later to Abseil Python guidance. ### ソース - - - - - ## セキュリティノート library-like package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - library-like package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** gflags - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - Debian apt - libgflags-dev - 2.2.2-2: normalized package name match | Debian stable package indexes: libgflags-dev from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | commandline flags module for C++ (development files) | https://gflags.github.io/gflags/ - Debian apt - libgflags-doc - 2.2.2-2: normalized package name match | Debian stable package indexes: libgflags-doc from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | documentation of gflags | https://gflags.github.io/gflags/ - Debian apt - libgflags2.2 - 2.2.2-2: normalized package name match | Debian stable package indexes: libgflags2.2 from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | commandline flags module for C++ (shared library) | https://gflags.github.io/gflags/ - Nix - gflags: normalized package name match | nixpkgs package indexes: pkgs/by-name/gf/gflags/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - libgflags-dev - 2.2.2-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: libgflags-dev from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | commandline flags module for C++ (development files) | https://gflags.github.io/gflags/ - Ubuntu apt - libgflags-doc - 2.2.2-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: libgflags-doc from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | documentation of gflags | https://gflags.github.io/gflags/ - Ubuntu apt - libgflags2.2 - 2.2.2-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: libgflags2.2 from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | commandline flags module for C++ (shared library) | https://gflags.github.io/gflags/ - apk - gflags - 2.3.0-r0: normalized package name match | Alpine Linux edge package indexes: gflags from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | The gflags package contains a C++ library that implements commandline flags processing. | https://gflags.github.io/gflags/ - apk - gflags-dev - 2.3.0-r0: normalized package name match | Alpine Linux edge package indexes: gflags-dev from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | The gflags package contains a C++ library that implements commandline flags processing.
