程序员常用文档查询工具

工欲善其事，必先利其器。这篇文章给大家介绍自己常用的一款文档文档查询利器，希望能帮助到大家。

Mac 版本叫Dash，windows版本对应的是zeal。

Dash官网介绍如下：

Dash is an API Documentation Browser and Code Snippet Manager. Dash instantly searches offline documentation sets for 200+ APIs, 100+ cheat sheets and more. You can even generate your own docsets or request docsets to be included.

Dash comes with 200+ offline documentation sets. You can choose which documentation sets to download and Dash will take care of the rest, making sure they are kept up to date. You can also generate your own docsets, request docsets or download docsets from third-party sources.

zeal官网有这样一句话:

These docsets are generously provided by Dash. You can also create your own!

zeal可提供的文档

这个文档工具可以同时安装不同版本的文档，对DBA来说，对比不同版本数据库的参数等非常方便。真香！

例如：查询MySQL某个innodb_log_file_size在不同版本的区别。
