+# Flagger
+
+Flagger is an arbitrary CLI flags parser, like argparse in Python.
+Flagger is able to parse boolean, integer and string flags.
+
+# Installation
+
+```
+go get -u -v lab.pztrn.name/golibs/flagger
+```
+
+# 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:
+
+```
+flgr = flagger.New(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:
+
+```
+flag_bool := Flag{
+    Name: "boolflag",
+    Description: "Boolean flag",
+    Type: "bool",
+    DefaultValue: true,
+}
+err := flgr.AddFlag(&flag_bool)
+if err != nil {
+    ...
+}
+```
+
+After adding all neccessary flags you should issue ``Parse()`` call to get
+them parsed:
+
+```
+flgr.Parse()
+```
+
+After parsed they can be obtained everywhere you want, like:
+
+```
+val, err := flgr.GetBoolValue("boolflag")
+if err != nil {
+    ...
+}
+```
+
+For more examples take a look at ``flagger_test.go`` file or [at GoDoc](https://github.com/pztrn/flagger).
