Flagger is an arbitrary CLI flags parser, like argparse in Python.
Flagger is able to parse boolean, integer and string flags.
# Installation
## Installation
```
```bash
go get -u -v go.dev.pztrn.name/flagger
```
# Usage
## Usage
Flagger requires logging interface to be passed on initialization.
See ``loggerinterface.go`` for required logging functions.
It is able to run with standart log package, in that case
initialize flagger like:
```
```go
flgr = flagger.New("My Super Program", flagger.LoggerInterface(log.New(os.Stdout, "testing logger: ", log.Lshortfile)))
flgr.Initialize()
```
Adding a flag is easy, just fill ``Flag`` structure and pass to ``AddFlag()`` call:
```
```go
flag_bool := Flag{
Name: "boolflag",
Description: "Boolean flag",
@ -41,23 +41,17 @@ if err != nil {
After adding all neccessary flags you should issue ``Parse()`` call to get
them parsed:
```
```go
flgr.Parse()
```
After parsed they can be obtained everywhere you want, like:
```
```go
val, err := flgr.GetBoolValue("boolflag")
if err != nil {
...
}
```
For more examples take a look at ``flagger_test.go`` file or [at GoDoc](https://godoc.org/gitlab.com/pztrn/flagger).
