minigli

minigli is a tiny command argument parser for Go.

Usage

minigli.Pack() returns MiniGli (and error check bool).

type MiniGli struct {
	Cmd	string           // Command 
	Subs	[]string         // Sub Commands 
	Longs	map[string]string// Options start with "--"
	Shorts	map[string]string// Options start with "-"
}

• Options are key-value pair given with 1 or 2 "-"s.
• Commands are the rest.
• Cmd is the first of Commands
• Subs are the rest.

e.g)

// your-cli verb target --option value -another:value target2
mg, ok := minigli.Pack()
if !ok {
    // Handle Invalid Argument.
    // Only "invalid option" occurs invalid argument.
    // "invalid option" will be explained later.
}

mg.Cmd // "verb"
mg.Subs// ["target", "target2"]
mg.Longs// {"option" : "value"}
mg.Shorts//{"another": "value"}

Options rule

Long option can be specified as below:

• --option value
• --option:value
• --option=value

Short option is same.

Key only option is specified like this:

• --opt:
• -opts=

Only last of arguments can be key only option withou ":" or "=".

Next are invalid options and Pack() fails to parse then returns false.

• --:SomeString
• -:ThisIsToo
