The README says it is commonly packaged as `deheader`. The NEWS file gives a long maintenance record beginning with 0.1 on 2010-12-01. Later releases added summary output, portability checks, duplicate include detection, Python 2/3 compatibility, Makefile-friendly exit status, GCC compatibility updates, and continued documentation and hardening fixes through 1.12 in 2026. ### 採用の歴史 deheader is packaged by Homebrew and appears upstream as a named package on the official project page. Its low-level C/C++ focus makes it more of a maintainer and build-hygiene tool than an end-user application. ### 使われ方 The package is used during source maintenance to test whether headers are actually required. Because it verifies removals by compilation, it belongs in the same toolbox as static-analysis and build-cleanup utilities rather than pure text linters. ### パッケージ好きにとっての重要性 deheader matters to package nerds because header bloat affects compile time, portability, and dependency clarity. It is especially relevant when distributions and maintainers need source trees to build cleanly across compilers, standard libraries, and Unix variants. ### タイムライン - 2010: 0.1 initial release. - 2016: 1.5 adds exit status behavior useful in Makefiles. - 2022: 1.8 changes the shebang to Python 3. - 2026: 1.12 is released. ### Related projects - The project is adjacent to C and C++ compiler toolchains, build systems, and static-analysis utilities that reduce unnecessary source dependencies. ### ソース - - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable 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:** deheader - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## 他のパッケージマネージャ記録 - Debian apt - deheader - 1.11-1: normalized package name match | Debian stable package indexes: deheader from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Find and remove unnecessary includes in C or C++ source files | http://www.catb.org/~esr/deheader/ - Nix - deheader: normalized package name match | nixpkgs package indexes: pkgs/by-name/de/deheader/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - deheader - 1.10-1: normalized package name match | Ubuntu 24.04 LTS package indexes: deheader from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Find and remove unnecessary includes in C or C++ source files | http://www.catb.org/~esr/deheader/ - zypper - deheader - 1.11-1.2: normalized package name match | openSUSE Tumbleweed package metadata: deheader from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | Find and optionally remove unneeded includes in C or C++ sourcefiles | http://www.catb.org/~esr/deheader/ ## 関連リンク - [Terminal utility packages](https://www.automicvault.com/ja/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/ja/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/ja/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/ja/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [asciidoctor](https://www.automicvault.com/ja/pkg/brew/asciidoctor/) - Build dependency declared by Homebrew. - [bcpp](https://www.automicvault.com/ja/pkg/brew/bcpp/) - Shares av.db curated category or tags: c, c-cpp, cli, cpp, developer-tools. - [include-what-you-use](https://www.automicvault.com/ja/pkg/brew/include-what-you-use/) - Shares av.db curated category or tags: c, cli, cpp, developer-tools, static-analysis. - [pmccabe](https://www.automicvault.com/ja/pkg/brew/pmccabe/) - Shares av.db curated category or tags: c, cli, cpp, developer-tools, static-analysis. - [abi-dumper](https://www.automicvault.com/ja/pkg/brew/abi-dumper/) - Shares av.db curated category or tags: c, cli, cpp, developer-tools. - [cbmc](https://www.automicvault.com/ja/pkg/brew/cbmc/) - Shares av.db curated category or tags: c, cli, developer-tools, static-analysis. - [ccheck](https://www.automicvault.com/ja/pkg/brew/ccheck/) - Shares av.db curated category or tags: c, cli, developer-tools, static-analysis. - [cflow](https://www.automicvault.com/ja/pkg/brew/cflow/) - Shares av.db curated category or tags: c, cli, developer-tools, static-analysis. - [clangql](https://www.automicvault.com/ja/pkg/brew/clangql/) - Shares av.db curated category or tags: cli, cpp, developer-tools, static-analysis. - [recc](https://www.automicvault.com/ja/pkg/brew/recc/) - Local package facts share a topical domain.
