TCommandLineReader

==================

 

This unit provides an advanced, platform-independent command line parser for Lazarus and Delphi.

It checks for allowed options, automatically prints a help with a list of all of them, and -- contrary to the parser in the rtl -- behaves the same on Windows and Linux.

Example:

 

 ```pascal

var cmdline: TCommandLineReader;

begin

  cmdline := TCommandLineReader.create;

  

  //Initial declaration of some command line parameters:

  cmdline.declareString('name', 'An example string property');

  cmdline.declareString('foo', 'Another example string property', 'bar');

  cmdline.declareInt('count', 'An example integer property', 123);

  cmdline.declareFlag('flag', 'An example boolean property');

  

  //cmdline.parse(); 

  

  

  

  //1. Parsing some command line options

  cmdline.parse('--name="some name" --count 9');

  

  cmdline.readString('name'); //some name

  cmdline.readString('foo');  //bar

  cmdline.readInt('count');   //9

  cmdline.readFlag('flag');   //false

  

  cmdline.existsProperty('name'); //true

  cmdline.existsProperty('foo');  //false

  

  //2. Parsing some other command line options

  cmdline.parse('--foo barbar --flag');

  

  cmdline.readString('name'); //

  cmdline.readString('foo');  //barbar

  cmdline.readInt('count');   //123

  cmdline.readFlag('flag');   //true

  

  cmdline.existsProperty('name'); //false

  cmdline.existsProperty('foo');  //true

  //3. Parsing some other command line options

  cmdline.parse('--help');

  

  //prints automatically generated help to stdout and halts:

  {

  The following command line options are valid: 

  --name= 	An example string property

  --foo=  	Another example string property (default: bar)

  --count=   	An example integer property (default: 123)

  --flag          	An example boolean property

  }

  //4. Some more advanced usage

  cmdline.addAbbreviation('f'); //abbreviation for the last option (--flag)

  cmdline.allowDOSStyle := true; //DOS slash options. Default is only true on Windows 

  

  cmdline.parse('/name "x y z" -f /count=1 /foo="abc"');

  cmdline.readString('name'); //x y z

  cmdline.readString('foo');  //abc

  cmdline.readInt('count');   //1

  cmdline.readFlag('flag');   //true

  

  cmdline.existsProperty('name'); //true

  cmdline.existsProperty('foo');  //true

  

```
