Gulp plugin that manages and inject dependency for redis lua script, so that the lua script can be written as composable modules

How to add dependency.

In the file that requires dependency add --@require 'FILE_NAME'; See below for example

--@require './log.lua';

local minuteKeys = redis.call('keys','*MYLIST');
for i,key in ipairs(minuteKeys) do
    redis.call("LTRIM",key,0 , 2000)
end

The output file will contain

--[[ Injected by lua-redis-dependency-manager 
-- /Users/AAravindan/dev/redis-lua-dependency-manager/lua-scripts/app/log.lua

-- dependent /Users/AAravindan/dev/redis-lua-dependency-manager/lua-scripts/app/ClearOldRecords.lua 
]]
local function log(logdata)
    redis.call('PUBLISH', 'debug', cjson.encode(logdata));
end
