## Project history and usage

flatcc is a FlatBuffers compiler and runtime library written in C for C. 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.
