basho/erlang_protobuffs

This system is a Protocol Buffers serialization library for Erlang, providing tools to generate and encode/decode messages. It features a refactored code generator that produces Erlang modules with robust support for nested types, extensions, and packed fields. The project has modernized its build infrastructure to use Rebar and includes comprehensive test coverage for all serialization features.

Users can now use the new \generate\_emakefile.escript\ to automatically generate an Emakefile that conditionally enables the Proper or EQC testing frameworks based on availability. Additionally, the new \mysql.escript\ allows users to generate protocol buffer message definitions directly from a MySQL table schema, mapping MySQL types to appropriate protocol buffer types.

scripts · high confidence

A new build script, build/publish, has been added to automate the creation of GitHub releases. The script accepts a version string (e.g., 1.0.0 or 1.0.0-beta1), validates it, and uses the GitHub API to create a new release with the appropriate pre-release flag. It requires a GitHub API token stored in $HOME/.ghapi and enforces that the script is run from the master branch for stable releases.

build · high confidence

The project has migrated its build system from Rake to Rebar, introducing a new rebar.config and updating the Makefile to support Rebar-based targets like compile, test, and release. Additionally, the repository now includes a .gitignore file to exclude generated files and build artifacts, and a .travis.yml file to configure continuous integration with Travis CI.

(repo-wide) · high confidence

The code generator (protobuffs\_compile) was refactored to use the erltl library and generate forms instead of raw strings, and now supports nested types, extensions, and package resolution. The core encoding and decoding logic was restructured: the public API now exposes encode/3, encode\_packed/3, decode/2, and decode\_packed/2, while internal functions like decode\many were removed or deprecated. The generated \\_pb.erl files now include specific encode/decode functions for each message type, handle extensions via a '$extensions' field, and support repeated fields and default values more robustly.

src · high confidence

The file support/include.mk, which previously managed the compilation of Erlang source files and templates into the ebin directory, has been removed. This eliminates the old build system, which handled tasks such as setting compiler flags for debug info and template processing, in favor of a newer build approach.

support · high confidence

Added comprehensive test coverage for the Protobuffs library; Expanded test coverage for Protocol Buffers features; Removed obsolete test suite and build file.
