配置事例
Lapis 的配置模块支持递归合并 table。
比如我们可以先定义一个基础配置，然后里面的值可以后期覆盖：
1
2
3
4
5
6
7
8
9
10
11
12
13
14

| -- config.moon
local config = require("lapis.config")
config({"development", "production"}, {
host = "example.com",
email_enabled = false,
postgres = {
host = "localhost",
port = "5432",
database = "my_app"
}
})
config("production", {
email_enabled = true,
postgres = {
database = "my_app_prod"
}
})
|
以下是上面的配置的解析出来的结果（默认值省略）：
1
2
3

| -- "development"
{
host = "example.com",
email_enabled = false,
postgres = {
host = "localhost",
port = "5432",
database = "my_app",
},
_name = "development"
}

},
_name = "production"
}

你可以通过 config 函数自定义配置你的应用配置，最终这些数据都会和配置的数据合并。
