## Disable sorting of flags
|
||||
`pflag` allows you to disable sorting of flags for help and usage message.
|
||||
|
||||
**Example**:
|
||||
```go
|
||||
flags.BoolP("verbose", "v", false, "verbose output")
|
||||
flags.String("coolflag", "yeaah", "it's really cool flag")
|
||||
flags.Int("usefulflag", 777, "sometimes it's very useful")
|
||||
flags.SortFlags = false
|
||||
flags.PrintDefaults()
|
||||
```
|
||||
**Output**:
|
||||
```
|
||||
-v, --verbose verbose output
|
||||
--coolflag string it's really cool flag (default "yeaah")
|
||||
--usefulflag int sometimes it's very useful (default 777)

## Supporting Go flags when using pflag

In order to support flags defined using Go's `flag` package, they must be added to the `pflag` flagset. This is usually necessary

to support flags defined by third-party dependencies (e.g. `golang/glog`).
