Version 2.9 via Homebrew; verified from local package data. ## Install ```sh sudo av install brew:cppp ``` Additional install commands: ### macOS - Homebrew (100%): ```sh brew install cppp ``` Evidence: local Homebrew formula metadata ## Package facts - **Package key:** brew:cppp - **Package manager:** Homebrew - **Package manager page:** - **Version:** 2.9 - **Source summary:** Partial Preprocessor for C - **Homepage:** - **Repository:** - **Upstream docs:** - **License:** GPL-2.0-or-later - **Source archive:** - **Generated:** 2026-07-08T07:18:31+00:00 ## Executables - cppp (cli) - cppp (alias) ## Install behavior - Post-install hook: not defined - Bottle: available on arm64_big_sur, arm64_linux, arm64_monterey, arm64_sequoia, arm64_sonoma, arm64_tahoe, arm64_ventura, big_sur, catalina, monterey, sonoma, ventura ## Freshness - Page generated: 2026-07-08 - Package-manager version: 2.9 - Local data: ok - Upstream repository: https://www.muppetlabs.com/~breadbox/software/cppp.html - info: No package-manager update timestamp was available. - info: Release/tag comparison is only available for GitHub repositories. ## Project history and usage cppp is a partial C preprocessor: it applies only the subset of conditional preprocessing decisions requested by the user. ### Project history The official page describes cppp as a focused tool for applying selected #ifdef, indeterminate preprocessor logic in place. ### Adoption history The project has a small distribution footprint, with the official page linking both a release tarball and the SourceHut repository. ### How it is used Users run cppp with macro symbols defined or undefined on the command line. The tool removes or simplifies conditional-inclusion blocks only when those symbols determine the result. ### Why package nerds care cppp is package-nerd interesting because it fills a narrow gap between doing no preprocessing and running the full C preprocessor, preserving source shape while pruning known feature branches. ### Timeline - Current release page: The official homepage links cppp-2.9.tar.gz. - Current source hosting: The official homepage links the SourceHut repository. ### Related projects - cppp is related to the C preprocessor, but it intentionally performs only partial conditional evaluation instead of full macro preprocessing. ### Sources - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cppp - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [fypp](https://www.automicvault.com/pkg/brew/fypp/) - Shares av.db curated category or tags: cli, developer-tools, preprocessor, preprocessors. - [gpp](https://www.automicvault.com/pkg/brew/gpp/) - Shares av.db curated category or tags: cli, developer-tools, preprocessor, preprocessors. - [fmpp](https://www.automicvault.com/pkg/brew/fmpp/) - Shares av.db curated category or tags: cli, developer-tools, preprocessors. - [mcpp](https://www.automicvault.com/pkg/brew/mcpp/) - Shares av.db curated category or tags: c, cli, developer-tools, preprocessor. - [aarch64-elf-gcc](https://www.automicvault.com/pkg/brew/aarch64-elf-gcc/) - Shares av.db curated category or tags: c, cli, developer-tools. - [abi-dumper](https://www.automicvault.com/pkg/brew/abi-dumper/) - Shares av.db curated category or tags: c, cli, developer-tools. - [aklomp-base64](https://www.automicvault.com/pkg/brew/aklomp-base64/) - Shares av.db curated category or tags: c, cli, developer-tools. - [astyle](https://www.automicvault.com/pkg/brew/astyle/) - Shares av.db curated category or tags: c, cli, developer-tools. - [fnlfmt](https://www.automicvault.com/pkg/brew/fnlfmt/) - Local package facts share a topical domain.
