1. About The project

This is a COBS implementation in Go and C with tests.

• The C code is copied from Wikipedia and adapted. Some other implementations did not pass all tests.
• The Go code was written from scratch after reviewing other implementations.

See TCOBS as an other possibility.

3. Folder Information

Folder	Content
src	C sources ready to be used in any C project
go	Go source
cgo	Go project for testing

4. Getting Started

• Clone the project with git clone git@github.com:rokath/cobs.git for example.

• Run go vet ./... to check build environment.

• Run go test ./... to perform tests. Can take a minute.

• Add src to your embedded project and use function COBSEncode to convert a buffer into COBS format. Or use function COBSDecode for the other direction.

• After transmitting one (or more) COBS package(s) transmit a 0-delimiter byte.

• Encoding is currently not implemented in Go, but its is no big deal to write an encoder in Go or an other language of your choice using the documentation.

• Anyway you can encode inside Go using function CEncode, which is a Go wrapper for the C COBSEncode function .

• Contributions are appreciated.

4.1. Prerequisites

• Just a C compiler and, for testing or, if using, a Go installation.

4.2. Installation

• To use COBS with Go execute go get github.com/rokath/cobs
• In your Go file: include( cobs github.com/rokath/cobs/go ), when using the Go code (decoding only).
• In your Go file: include( cobs github.com/rokath/cobs/c ), when using the CGO code (encoding and decoding).

4.3. Roadmap

• Add Changelog
• Add back to top links
• Add Go Reader & Writer interface
• Add Additional Templates w/ Examples

See the open issues for a full list of proposed features (and known issues).
