Its README emphasizes minimal dependencies, generated C headers, a standalone flatcc executable, and runtime libraries for building, verifying, parsing, and printing FlatBuffers. ### Project history The official git history starts with an initial public release v0.1.0 on 2015-11-09. The README explains that flatcc is implemented as a standalone tool rather than as an extension of Google's flatc so it can provide a pure portable C schema compiler and fail gracefully on abusive input in long-running processes. ### Adoption history flatcc serves C projects that want FlatBuffers compatibility without pulling in a C++ compiler/runtime model. Its README describes CI-tested Ubuntu, macOS, and Windows support, user-reported portability, and a no-CMake integration path once the generator has produced headers. ### How it is used Users build flatcc, run it against .fbs schema files, include generated headers, and link only the needed C runtime files. The README contrasts flatcc's runtime JSON handling with Google's flatc command-line JSON conversion, presenting the tools as complementary. ### Why package nerds care flatcc is package-nerd significant because it is a compatibility-layer package: it tracks the FlatBuffers format while optimizing for C-only consumers, small binaries, generated headers, and vendorable runtime source files. ### Timeline - 2015: Initial public release v0.1.0. - 2016: v0.4.0 tag; README notes big-endian support as of release 0.4.0. - 2022: v0.6.1 tag appears in the official git history. ### Related projects - The README explicitly relates flatcc to Google FlatBuffers and the flatc compiler, while distinguishing flatcc as the FlatBuffers C Compiler. ### Sources - - - ## Security Notes library-like package without higher-risk signals. - **Geiger risk:** green / low - library-like package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** flatcc - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - flatcc: normalized package name match | nixpkgs package indexes: pkgs/by-name/fl/flatcc/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [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. - [cmake](https://www.automicvault.com/pkg/brew/cmake/) - Build dependency declared by Homebrew. - [planus](https://www.automicvault.com/pkg/brew/planus/) - Shares av.db curated category or tags: cli, compiler, developer-tools, flatbuffers, serialization. - [protobuf-c](https://www.automicvault.com/pkg/brew/protobuf-c/) - Shares av.db curated category or tags: c, cli, developer-tools, library, serialization. - [check](https://www.automicvault.com/pkg/brew/check/) - Shares av.db curated category or tags: c, cli, developer-tools, library. - [flatbuffers](https://www.automicvault.com/pkg/brew/flatbuffers/) - Shares av.db curated category or tags: cli, developer-tools, library, serialization. - [nanopb](https://www.automicvault.com/pkg/brew/nanopb/) - Shares av.db curated category or tags: c, cli, developer-tools, serialization. - [capnp](https://www.automicvault.com/pkg/brew/capnp/) - Shares av.db curated category or tags: cli, developer-tools, serialization. - [cdecl](https://www.automicvault.com/pkg/brew/cdecl/) - Shares av.db curated category or tags: c, cli, developer-tools. - [dhall-json](https://www.automicvault.com/pkg/brew/dhall-json/) - Shares av.db curated category or tags: cli, compiler, developer-tools, serialization. ## Combined YAML source View the package source record on GitHub.
