ARGV
Extension for ARGV obj. With this extension module, you can parse in an easy way the script input tags
example
require 'argv'
#$ ruby sample/test.rb -x -zsa yo --test test this ok
ARGV.to_hash
#> {"test"=>"test",["z","s","a"]=>"yo"}
ARGV.to_hash(multi_value: true)
ARGV.to_hash(true)
#> {"test"=>["test", "this", "ok"],["z","s","a"]=>["yo"]}
ARGV.values
#> ["test", "this", "ok", "yo"]
ARGV.long_options
#> ["test"]
ARGV.short_options
#> ["x","z","s","a"]
ARGV.options
#> ["x","z","s","a","test"]
#$ ruby sample/test.rb -hy -sx as --hello-world test test2
ARGV.to_hash
#> {["s", "x"]=>"as", "hello-world"=>"test"}
ARGV.to_hash(true)
#> {["s", "x"]=>["as"], "hello-world"=>["test", "test2"]}
For Modules
if you write module and you want to have some custom tags and help msg for that, use the following example
require 'argv'
ARGVEXT.add_help_msg "This will show you the help msg (this)",:helper,:help,:h
#
# ARGVEXT.help_msg or show_help will read on your values and will produce the following with this example
#
# This will show you the help msg (this)
# --helper
# --help
# -h
# this will run on the terminal and break Process,
# if the user give one of the helper tags as argv
Test
- you can find a test file in the sample named as "test"
