-- This directory is used to define user specific rules and plugins for Rspamd in Lua
-- Each *.lua file is executed and added to the Rspamd

-- Example of regexp rule:

local reconf = config['regexp'] -- Create alias for regexp configs

local re1 = 'From=/foo@/H' -- Mind local here
local re2 = '/blah/P'

reconf['SYMBOL'] = {
  re = string.format('(%s) && !(%s)', re1, re2), -- use string.format to create expression
  score = 1.2,
  description = 'some description',

  condition = function(task)
    -- run this rule only if some condition is satisfied
    return true
  end,
}

-- Example of a simple lua rule:
rspamd_config.SYMBOL = {
  callback = function(task)
    return true
  end,
  score = 1.2,
  description = 'some description',

  condition = function(task)
    -- run this rule only if some condition is satisfied
    return true
  end,
}

-- Example of a plugin with configuration:
local redis_params
local lua_redis = require "lua_redis"

local function symbol_cb(task)
  local function redis_set_cb(err)
    if err ~= nil then
      rspamd_logger.errx(task, 'redis_set_cb received error: %1', err)
    end
  end
  -- Create hash of message-id and store to redis
  local key = make_key(task)
  local ret = lua_redis.redis_make_request(task,
      redis_params, -- connect params
      key, -- hash key
      true, -- is write
      redis_set_cb, --callback
      'SETEX', -- command
      { key, tostring(settings['expire']), "1" } -- arguments
  )
end

-- Load redis server for module named 'module'
redis_params = lua_redis.parse_redis_server('module')
if redis_params then
  -- Register symbol
end
