# cli Source
|
||
|
|
|
||
|
|
The cli source reads config from parsed flags via a cli.Context.
|
||
|
|
|
||
|
|
## Format
|
||
|
|
|
||
|
|
We expect the use of the `micro/cli` package. Upper case flags will be lower cased. Dashes will be used as delimiters for nesting.
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
```go
|
||
|
|
micro.Flags(
|
||
|
|
cli.StringFlag{
|
||
|
|
Name: "database-address",
|
||
|
|
Value: "127.0.0.1",
|
||
|
|
Usage: "the db address",
|
||
|
|
},
|
||
|
|
cli.IntFlag{
|
||
|
|
Name: "database-port",
|
||
|
|
Value: 3306,
|
||
|
|
Usage: "the db port",
|
||
|
|
},
|
||
|
|
)
|
||
|
|
```
|
||
|
|
|
||
|
|
Becomes
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"database": {
|
||
|
|
"address": "127.0.0.1",
|
||
|
|
"port": 3306
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## New and Load Source
|
||
|
|
|
||
|
|
Because a cli.Context is needed to retrieve the flags and their values, it is recommended to build your source from within a cli.Action.
|
||
|
|
|
||
|
|
```go
|
||
|
|
|
||
|
|
func main() {
|
||
|
|
// New Service
|
||
|
|
service := micro.NewService(
|
||
|
|
micro.Name("example"),
|
||
|
|
micro.Flags(
|
||
|
|
cli.StringFlag{
|
||
|
|
Name: "database-address",
|
||
|
|
Value: "127.0.0.1",
|
||
|
|
Usage: "the db address",
|
||
|
|
},
|
||
|
|
),
|
||
|
|
)
|
||
|
|
|
||
|
|
var clisrc source.Source
|
||
|
|
|
||
|
|
service.Init(
|
||
|
|
micro.Action(func(c *cli.Context) {
|
||
|
|
clisrc = cli.NewSource(
|
||
|
|
cli.Context(c),
|
||
|
|
)
|
||
|
|
// Alternatively, just setup your config right here
|
||
|
|
}),
|
||
|
|
)
|
||
|
|
|
||
|
|
// ... Load and use that source ...
|
||
|
|
conf := config.NewConfig()
|
||
|
|
conf.Load(clisrc)
|
||
|
|
}
|
||
|
|
```
