Reliable official narrative history is thin, so this enrichment keeps the history to the GNU identity, source hosting, and package-manager role. ### Adoption history The input package facts show cflow packaged in Homebrew, Alpine, Debian/Ubuntu, Fedora, MacPorts, Nix, openSUSE, and other Unix-like package ecosystems. ### How it is used cflow is used by C programmers and maintainers to inspect function relationships and call graphs from source trees, usually as a command-line aid during code reading or static analysis. ### Why package nerds care GNU cflow is a classic small GNU utility: old-school source inspection, text output, manual pages, init files, and broad distro packaging without a large service footprint. ### Timeline - GNU project: cflow is maintained as GNU software. - Savannah era: official source repository hosted on git.savannah.gnu.org. - Current packaging: input facts show broad availability across Unix package managers. ### Related projects - GNU cflow sits near other source-reading and static-analysis command-line tools rather than compilers or language servers. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: ~/.cflow.d/*.cfo, ~/.cflow.d/default.cfo, /usr/share/cflow/site-init/*.cfo, /usr/share/cflow/site-init/1.8/*.cfo, /usr/local/share/cflow/site-init/*.cfo, /usr/local/share/cflow/site-init/1.8/*.cfo, $CFLOWRC, ~/.cflowrc ## Other Package-Manager Records - Debian apt - cflow - 1:1.7-5: normalized package name match | Debian stable package indexes: cflow from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | control flow analyzer for C source files | https://www.gnu.org/software/cflow - Debian apt - cflow-doc - 1:1.7-5: normalized package name match | Debian stable package indexes: cflow-doc from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | control flow analyzer for C source files (documentation) | https://www.gnu.org/software/cflow - Debian apt - cflow-l10n - 1:1.7-5: normalized package name match | Debian stable package indexes: cflow-l10n from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | control flow analyzer for C source files (localization files) | https://www.gnu.org/software/cflow - Nix - cflow: normalized package name match | nixpkgs package indexes: pkgs/by-name/cf/cflow/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - cflow - 1:1.7-5: normalized package name match | Ubuntu 24.04 LTS package indexes: cflow from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | control flow analyzer for C source files | https://www.gnu.org/software/cflow - Ubuntu apt - cflow-doc - 1:1.7-5: normalized package name match | Ubuntu 24.04 LTS package indexes: cflow-doc from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | control flow analyzer for C source files (documentation) | https://www.gnu.org/software/cflow - Ubuntu apt - cflow-l10n - 1:1.7-5: normalized package name match | Ubuntu 24.04 LTS package indexes: cflow-l10n from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | control flow analyzer for C source files (localization files) | https://www.gnu.org/software/cflow - apk - cflow - 1.8-r0: normalized package name match | Alpine Linux edge package indexes: cflow from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | A C program flow analyzer | https://www.gnu.org/software/cflow/ - apk - cflow-doc - 1.8-r0: normalized package name match | Alpine Linux edge package indexes: cflow-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | A C program flow analyzer (documentation) | https://www.gnu.org/software/cflow/ - apk - cflow-lang - 1.8-r0: normalized package name match | Alpine Linux edge package indexes: cflow-lang from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Languages for package cflow | https://www.gnu.org/software/cflow/ - dnf - cflow - 1.8-4.fc45: normalized package name match | Fedora Rawhide package metadata: cflow from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/07190dc5ae9f35ae73866675fed6d95fe6e8d9fe22c9d7cdf85862cb2ed24a4c-primary.xml.zst | Analyzes C files charting control flow within the program | http://www.gnu.org/software/cflow/ - zypper - cflow - 1.8-2.5: normalized package name match | openSUSE Tumbleweed package metadata: cflow from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | Tool to generate flowcharts for C sources | https://www.gnu.org/software/cflow - MacPorts - cflow: normalized package name match | MacPorts ports tree: devel/cflow/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
