Implementing Redis commands currently require writing a lot of scaffolding code because the module doesn't have a knowledge of the type of data it can receive, only if they can be long and therefore be processed as stream of data or if they can be short enough to be read entirely in one go from the buffer.

The redis repository contains a number of json files, one per command, with the specs of the commands themselves (e.g. the command name, the command group, the ACLs required, the parameters it takes, the specifics for the key, etc.).

It's necessary to implement a command generator that will:

• automatically generate the necessary data structs for the commands
• automatically generate all the scaffolding code for these commands to handle keys, values, tokens and tokens parameters, filling as needed the data struct for the command
• automatically take care of handling common errors (e.g. key too long, unsupported parameter, missing parameter for a specified token, etc.)

It's necessary to analize the json structure before investigating how to build the generator
