history
Project history and usage
GNU cflow is a GNU command-line developer tool for generating call graphs from C source code.
Project history
The official GNU project page and manual are the primary documentation surfaces, and the official source repository is hosted on GNU Savannah. 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.

Recommended review
Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
