-- remove_filter.lua

-- Distributed under terms of the MIT license.

-- 使用 text dada 建立屏蔽 candidate

-- 屏蔽 filename: user_data_dir/[name_space].txt

-- 透過 property "delete_candidate" 來更新 Rmdb

-- 增加 property 'delect_candidate' 'reload' 重載入檔案

-- 增加 property 'delect_candidate' 'enable' enable append() find() match()

-- 增加 property 'delect_candidate' 'disable' disable append() find() match()

-- 增加 property 'delect_candidate' 'toggle' enable or disable append() find() match()

-- Rmdb module

-- Rmdb(filename)

-- Rmdb:load() -- reloda text file

-- Rmdb:append() -- update text file

-- Rmdb:find(word) or Rmdb:match(word) -- return bool

-- Rmdb:enable(nil|true|false) return bool | set and return

-- Rmdb:toggle() return bool
