|
19
|
|
|
* 1. 所有行会经过两边去白处理 |
|
20
|
|
|
* 2. 英文分号（;），井号（#）开头的会被认为是注释，直接被舍弃 |
|
21
|
|
|
* 3. 配置为键值对形式：[key]=[value]，等号两边空白会被舍弃 |
|
22
|
|
|
* 4. 整个值如果被中括号（[]）包裹，则值会被英文逗号（,）分割为数组 |
|
23
|
|
|
* 4. 如果一整行被中括号（[]）包裹，则该行被认为是个组，组名是中括号里的字符串 |
|
24
|
|
|
* 5. 分组下的配置如果出现空白行，则重新分组 |
|
25
|
|
|
* 6. 同名配置后者覆盖前者 |
