Experimenting with Vedis from C and Go

Just playing around with Vedis and refreshing my rusty C programming skills.

Vedis?

Vedis is an embeddable datastore C library built with over 70 commands similar in concept to Redis but without the networking layer since Vedis run in the same process of the host application.

Requirements

The CGO bindings to Vedis:

$ go get github.com/icholy/vedis

Usage

$ make
Building the examples:
go build -o bin/example-from-go example.go
gcc example.c vedis.c -o bin/example-from-c

Running C example:

 foo: DATA FROM C

Running Go example:

 foo: DATA FROM C
 bar: 123

Contents of the data.vdb

$ hexdump -C data.vdb
