ProcessCommandLineArguments ( IList args, string>.ICollection options, string atFolder, string>.IDictionary shortOptions = null, InvertibleSet twoArgOptions = null, int argLimit = 0xFFFF, bool expandEnvVars = true, bool caseSensitiveLongOpts = false ) : void

Expands environment variables (e.g. %TEMP%) and @files in a list of command-line arguments, and adds any options of the form "--opt" or "--opt=value" to a dictionary.

Two types of options are recognized, short (-s) and long (--long), and only one argument is supported per option. The documentation is above. You can choose whether to permit duplicate options or not. If you use a standard Dictionary{K,V} to hold the options, an exception will occur when this method calls Add() to add the duplicate. The exception is caught, the first ocurrance is kept, and a warning message is printed to MessageSink.Default. To allow duplicates, store options in a different data structure such as List(KeyValuePair(string, string)) or BMultiMap(string,string). DOS-style slash-options like /foo are not supported. Since Windows recognizes the forward slash as a path separator, forward-slash options can be recognized as paths. If you want to recognize them as options instead, you can preprocess the argument list, replacing every command that starts with "/" with a "--" command: for (int i = 0; args.Count > i; i++) if (args[i].StartsWith("/")) args[i] = "--" + args[i].Substring(1); Globs (e.g. *.txt) are not recognized or expanded, but environment variables are expanded when expandEnvVars is true. Quote marks are not processed. An argument of "--a", with quote marks, is not recognized as an option (these quote marks should be removed before calling this method, e.g. G.SplitCommandLineArguments handles this.)

args IList The original arguments to process.
options string>.ICollection Any long options (arguments that start with "--") /// will be added to this dictionary, and removed from args. This /// parameter cannot be null. /// By default, long options are not case sensitive. In that case, the /// user's option name is converted to lower case. /// /// Long options are expected to have the form --ID or --ID=value, where ID /// matches the regex "[a-zA-Z_0-9-]+". If there is no "=" or ":", that's /// okay too. For example, --Id{foo} is equivalent to --Id={foo}; both yield /// in the name-value pair ("id", "{foo}"). If there is no value (no equals /// or colon), the value associated with the option is null.
atFolder string If a parameter has the form @filename, the folder /// specified by atFolder will be searched for an options text file with the /// user-specified filename, and the contents of the file will be expanded /// into the list of arguments (split using SplitCommandLineArguments). The /// expanded list can contain new @filenames, which are also processed. To /// search in the current directory, use "". The @filename may use an absolute /// path, which overrides this folder. To disable @filename expansion, set /// this parameter to null. Whether the feature is enabled or disabled, /// @filenames are not removed from args, in case you want to /// be aware of the filenames afterward.
shortOptions string>.IDictionary A map from one-letter options that start with /// "-" rather than "--", to the name of the corresponding long option (this /// option can be null to ignore all short options.) For example, if this /// contains ('a', "all"), and the input args contains "-a:foo", /// the pair ("all", "foo") will be added to options. If a value in /// this map is null, the key itself is used. Short options can be combined; /// for example -abc:foo is equivalent to -a -b -c:foo. Short /// options are always case-sensitive; to define an option that is not case /// sensitive, place two entries in the dictionary e.g. ('a', "all") and /// ('A', "all"). If the user specifies a short option letter that is not /// recognized, the entire command will be ignored and left in args. For /// example, if shortOptions contains only ('a', "all") but args /// contains "-ab=foo", the command is ignored and left in args. /// Rationale: -ab=foo might be a filename. /// /// On the other hand, if -a is a valid option then -a123 is also /// valid even when there is no option called '1'; the number "123" is /// treated as an argument to -a. Now, if '1' is a registered short option /// but '2' is not, then -a123 is equivalent to -a -1=23. ///
twoArgOptions InvertibleSet A set of options in which the argument can /// be separated by a space from the option. For example, if the input is /// "--out foo.txt" and you want to recognize "foo.txt" as the argument to /// "--out", add the string "out" to this set. If you want to treat all /// options this way, use InvertibleSet{string}.All. Note: /// If the input is "--out:foo bar", "foo" is recognized as the argument to /// "--out" and "bar" is left alone, i.e. it is treated as unrelated. /// Short options participate automatically. For example if "-f" means /// "--foo", and twoArgOptions contains "foo", then "-f arg" is interpreted /// like "--foo=arg". /// /// The argument will not be treated as an argument if it starts with a /// dash, e.g. in --foo -*, -* will not be treated as an /// argument to --foo, even if -* is not a registered option. ///
argLimit int A limit placed on the number of arguments when /// expanding @files. Such a file may refer to itself, and this is the only /// protection provided against infinite recursive expansion.
expandEnvVars bool If true, environment variable references /// such as %TEMP% are expanded by calling the standard method /// .
caseSensitiveLongOpts bool If true, long options are case- /// sensitive. By default, long options are not case sensitive.
