Creating a redis Module in 15 lines of code!

A quick guide to write a very very simple "ECHO" style module to redis and load it. It's not really useful of course, but the idea is to illustrate how little boilerplate it takes.

Step 1: open your favorite editor and write/paste the following code in a file called module.c

#include "redismodule.h"
/* ECHO <string> - Echo back a string sent from the client */
int EchoCommand(RedisModuleCtx *ctx, RedisModuleString **argv, int argc) {

seq -f “%09.0f” 000000000 999999999 | sed -e ‘s/^$.\{3\}$$.\{2\}$$.\{4\}$/\1-\2-\3/’ | parallel -j16 –pipe ‘ruby -r digest/md5 -n -e “\$_.chomp!; puts "%s %s" % [\$_, Digest::MD5.hexdigest(\$_)]”’ > ssns

Aestheticization

The process of creating a layer of superficial simplicity, harmony and normalcy as an aid to denial of underlying complexity, dissonance and strangeness.

Gource

Gource is a software version control visualization tool.

Software projects are displayed by Gource as an animated tree with the root directory of the project at its centre. Directories appear as branches with files as leaves. Developers can be seen working on the tree at the times they contributed to the project.
