Its rationale is explicit: McCabe-style scoring and `pmccabe` are useful for testing effort, but GNU Complexity tries to better rank functions that are difficult for humans to understand by considering length, nesting, switch bodies, and complicated boolean expressions. ### Adoptionsgeschichte GNU Complexity has a narrow adoption footprint compared with larger GNU developer tools. Its significance is in the code-review and maintenance niche: it gives C maintainers a command-line metric that can point to suspicious functions in unfamiliar code, estimate testing or comprehension effort, and produce sorted score tables and histograms. ### Wie es verwendet wird Practitioners run `complexity` over C source files to report procedure scores, line counts, source locations, and optional histograms. The manual's example runs the tool against its own source with a low threshold, illustrating use as a quick audit tool for ranking functions before refactoring or review. ### Warum Paket-Nerds sich dafür interessieren For package nerds, GNU Complexity is interesting because it embodies a Unix-tool approach to maintainability: one command, text output, tunable thresholds, and a documented scoring model. It is useful in distributions as a lightweight companion to older tools such as `pmccabe` rather than as a large static-analysis framework. ### Zeitleiste - 2011: GNU Complexity web page and manual documented version 0.4. - 2011: Manual rationale compared GNU Complexity with `pmccabe` and explained its scoring model. ### Related projects - `pmccabe` is the comparison point used throughout the GNU Complexity manual. - `unifdef` is discussed in the parsing model as a way to handle preprocessor-conditional source. ### Quellen - - ## Sicherheitshinweise narrow executable package without higher-risk signals. - **Geiger-Risiko:** grün / niedrig - narrow executable package without higher-risk signals ## Details aus der Quelldatenbank - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** gnu-complexity - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Andere Paketmanager-Einträge - Debian apt - complexity - 1.13-1+b1: installed executable or alias match | Debian stable package indexes: complexity from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | tool for analyzing the complexity of C program functions | https://gnu.org/software/complexity - Debian apt - complexity-doc - 1.13-1: installed executable or alias match | Debian stable package indexes: complexity-doc from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | tool for analyzing the complexity of C program (documentation) | https://gnu.org/software/complexity - Nix - complexity: installed executable or alias match | nixpkgs package indexes: pkgs/by-name/co/complexity/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - complexity - 1.13-1: installed executable or alias match | Ubuntu 24.04 LTS package indexes: complexity from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | tool for analyzing the complexity of C program functions | https://gnu.org/software/complexity - Ubuntu apt - complexity-doc - 1.13-1: installed executable or alias match | Ubuntu 24.04 LTS package indexes: complexity-doc from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | tool for analyzing the complexity of C program (documentation) | https://gnu.org/software/complexity - zypper - complexity - 1.13-1.9: installed executable or alias match | openSUSE Tumbleweed package metadata: complexity from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | C source code complexity computation utility | https://www.gnu.org/software/complexity/ ## Verwandte Links - [Terminal utility packages](https://pkg.so/de/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/de/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://pkg.so/de/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://pkg.so/de/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [autogen](https://pkg.so/de/brew/autogen/) - Runtime dependency declared by Homebrew. - [autoconf](https://pkg.so/de/brew/autoconf/) - Build dependency declared by Homebrew. - [automake](https://pkg.so/de/brew/automake/) - Build dependency declared by Homebrew. - [pmccabe](https://pkg.so/de/brew/pmccabe/) - Shares pkgdb curated category or tags: c, cli, code-metrics, developer-tools, static-analysis. - [cppcheck](https://pkg.so/de/brew/cppcheck/) - Shares pkgdb curated category or tags: c, cli, developer-tools, static-analysis. - [include-what-you-use](https://pkg.so/de/brew/include-what-you-use/) - Shares pkgdb curated category or tags: c, cli, developer-tools, static-analysis. - [lizard-analyzer](https://pkg.so/de/brew/lizard-analyzer/) - Shares pkgdb curated category or tags: cli, code-metrics, developer-tools, static-analysis. - [sparse](https://pkg.so/de/brew/sparse/) - Shares pkgdb curated category or tags: c, cli, developer-tools, static-analysis. - [cbmc](https://pkg.so/de/brew/cbmc/) - Shares pkgdb curated category or tags: c, cli, developer-tools, static-analysis. - [cflow](https://pkg.so/de/brew/cflow/) - Shares pkgdb curated category or tags: c, cli, developer-tools, static-analysis. - [coccinelle](https://pkg.so/de/brew/coccinelle/) - Shares pkgdb curated category or tags: c, cli, developer-tools, static-analysis. - [gnu-indent](https://pkg.so/de/brew/gnu-indent/) - Package names and metadata indicate a similar tool family.
