If the -// format string ends in a '=', it has a required value. If the format -// string ends in a ':', it has an optional value. If neither '=' or ':' -// is present, no value is supported. `=' or `:' need only be defined on one -// alias, but if they are provided on more than one they must be consistent. -// -// Each alias portion may also end with a "key/value separator", which is used -// to split option values if the option accepts > 1 value. If not specified, -// it defaults to '=' and ':'. If specified, it can be any character except -// '{' and '}' OR the *string* between '{' and '}'. If no separator should be -// used (i.e. the separate values should be distinct arguments), then "{}" -// should be used as the separator. -// -// Options are extracted either from the current option by looking for -// the option name followed by an '=' or ':', or is taken from the -// following option IFF: -// - The current option does not contain a '=' or a ':' -// - The current option requires a value (i.e. not a Option type of ':') -// -// The `name' used in the option format string does NOT include any leading -// option indicator, such as '-', '--', or '/'. All three of these are -// permitted/required on any named option. -// -// Option bundling is permitted so long as: -// - '-' is used to start the option group -// - all of the bundled options are a single character -// - at most one of the bundled options accepts a value, and the value -// provided starts from the next character to the end of the string. -// -// This allows specifying '-a -b -c' as '-abc', and specifying '-D name=value' -// as '-Dname=value'. -// -// Option processing is disabled by specifying "--". All options after "--" -// are returned by OptionSet.Parse() unchanged and unprocessed. -// -// Unprocessed options are returned from OptionSet.Parse(). -// -// Examples: -// int verbose = 0; -// OptionSet p = new OptionSet () -// .Add ("v", v => ++verbose) -// .Add ("name=|value=", v => Console.WriteLine (v)); -// p.Parse (new string[]{"-v", "--v", "/v", "-name=A", "/name", "B", "extra"}); -// -// The above would parse the argument string array, and would invoke the -// lambda expression three times, setting `verbose' to 3 when complete. -// It would also print out "A" and "B" to standard output. -// The returned array would contain the string "extra". -// -// C# 3.0 collection initializers are supported and encouraged: -// var p = new OptionSet () { -// { "h|?|help", v => ShowHelp () }, -// }; -// -// System.ComponentModel.TypeConverter is also supported, allowing the use of -// custom data types in the callback type; TypeConverter.ConvertFromString() -// is used to convert the value option to an instance of the specified -// type: -// -// var p = new OptionSet () { -// { "foo=", (Foo f) => Console.WriteLine (f.ToString ()) }, -// }; -// -// Random other tidbits: -// - Boolean options (those w/o '=' or ':' in the option format string) -// are explicitly enabled if they are followed with '+', and explicitly -// disabled if they are followed with '-': -// string a = null; -// var p = new OptionSet () { -// { "a", s => a = s }, -// }; -// p.Parse (new string[]{"-a"}); // sets v != null -// p.Parse (new string[]{"-a+"}); // sets v != null -// p.Parse (new string[]{"-a-"}); // sets v == null -// - -using System; -using System.Collections; -using System.Collections.Generic; -using System.Collections.ObjectModel; -using System.ComponentModel; -using System.Globalization; -using System.IO; -using System.Runtime.Serialization; -using System.Security.Permissions; -using System.Text; -using System.Text.RegularExpressions; - -#if LINQ -using System.Linq; -#endif - -#if TEST -using NDesk.Options; -#endif - -#if NDESK_OPTIONS -namespace NDesk.Options -#else -namespace Mono.Options -#endif -{ - public class OptionValueCollection : IList, IList { - - List values = new List (); - OptionContext c; - - internal OptionValueCollection (OptionContext c) - { - this.c = c; - } - - #region ICollection - void ICollection.CopyTo (Array array, int index) {(values as ICollection).CopyTo (array, index);} - bool ICollection.IsSynchronized {get {return (values as ICollection).IsSynchronized;}} - object ICollection.SyncRoot {get {return (values as ICollection).SyncRoot;}} - #endregion - - #region ICollection - public void Add (string item) {values.Add (item);} - public void Clear () {values.Clear ();} - public bool Contains (string item) {return values.Contains (item);} - public void CopyTo (string[] array, int arrayIndex) {values.CopyTo (array, arrayIndex);} - public bool Remove (string item) {return values.Remove (item);} - public int Count {get {return values.Count;}} - public bool IsReadOnly {get {return false;}} - #endregion - - #region IEnumerable - IEnumerator IEnumerable.GetEnumerator () {return values.GetEnumerator ();} - #endregion - - #region IEnumerable - public IEnumerator GetEnumerator () {return values.GetEnumerator ();} - #endregion - - #region IList - int IList.Add (object value) {return (values as IList).Add (value);} - bool IList.Contains (object value) {return (values as IList).Contains (value);} - int IList.IndexOf (object value) {return (values as IList).IndexOf (value);} - void IList.Insert (int index, object value) {(values as IList).Insert (index, value);} - void IList.Remove (object value) {(values as IList).Remove (value);} - void IList.RemoveAt (int index) {(values as IList).RemoveAt (index);} - bool IList.IsFixedSize {get {return false;}} - object IList.this [int index] {get {return this [index];} set {(values as IList)[index] = value;}} - #endregion - - #region IList - public int IndexOf (string item) {return values.IndexOf (item);} - public void Insert (int index, string item) {values.Insert (index, item);} - public void RemoveAt (int index) {values.RemoveAt (index);} - - private void AssertValid (int index) - { - if (c.Option == null) - throw new InvalidOperationException ("OptionContext.Option is null."); - if (index >= c.Option.MaxValueCount) - throw new ArgumentOutOfRangeException ("index"); - if (c.Option.OptionValueType == OptionValueType.Required && - index >= values.Count) - throw new OptionException (string.Format ( - c.OptionSet.MessageLocalizer ("Missing required value for option '{0}'."), c.OptionName), - c.OptionName); - } - - public string this [int index] { - get { - AssertValid (index); - return index >= values.Count ?
