Package mflag (aka multiple-flag) implements command-line flag parsing.
|
|
It's an **hacky** fork of the [official golang package](http://golang.org/pkg/flag/)
|
|
|
|
It adds:
|
|
|
|
* both short and long flag version
|
|
`./example -s red` `./example --string blue`
|
|
|
|
* multiple names for the same option
|
|
```
|
|
$>./example -h
|
|
Usage of example:
|
|
-s, --string="": a simple string
|
|
```
|
|

It is very flexible on purpose, so you can do things like:
|
|
```
|
|
$>./example -h
|
|
Usage of example:
|
|
-s, -string, --string="": a simple string
|
|
```
|
|
|
|
Or:
|
|
```
|
|
$>./example -h
|
|
Usage of example:
|
|
-oldflag, --newflag="": a simple string
|
|
```
|
|
|
|
You can also hide some flags from the usage, so if we want only `--newflag`:
|
|
```
|
|
$>./example -h
|
|
Usage of example:
|
|
--newflag="": a simple string
|
|
$>./example -oldflag str
|
|
str
|
|
```
|
|
|
|
