/**
TDECmdLineArgs provides simple access to the command-line arguments
for an application. It takes into account Qt-specific options,
KDE-specific options and application specific options.
This class is used in %main() via the static method
init().
A typical %KDE application using %TDECmdLineArgs should look like this:
<pre>
int main(String[] args)
{
// Initialize command line args
TDECmdLineArgs.init(args, appName, programName, description, version);
// Tell which options are supported
TDECmdLineArgs.addCmdLineOptions( options );
// Add options from other components
KUniqueApplication.addCmdLineOptions();
....
// Create application object without passing 'argc' and 'argv' again.
KUniqueApplication app;
....
// Handle our own options/arguments
// A TDEApplication will usually do this in main but this is not
// necessary.
// A KUniqueApplication might want to handle it in newInstance().
TDECmdLineArgs args = TDECmdLineArgs.parsedArgs();
// A binary option (on / off)
if (args.isSet("some-option"))
....
// An option which takes an additional argument
String anotherOptionArg = args.getOption("another-option");
// Arguments (e.g. files to open)
for(int i = 0; i < args.count(); i++) // Counting start at 0!
{
// don't forget to convert to Unicode!
openFile( TQFile.decodeName( args.arg(i)));
// Or more convenient:
// openURL( args.url(i));
}
args.clear(); // Free up some memory.
....
}
</pre>
The options that an application supports are configured using the
String[][] class. An example is shown below:
<pre>
static String[][] options =
{
{ "a", I18N_NOOP("A short binary option"), 0 },
{ "b \<file>", I18N_NOOP("A short option which takes an argument"), 0 },
{ "c \<speed>", I18N_NOOP("As above but with a default value"), "9600" },
{ "option1", I18N_NOOP("A long binary option, off by default"), 0 },
{ "nooption2", I18N_NOOP("A long binary option, on by default"), 0 },
{ ":", I18N_NOOP("Extra options:"), 0 },
{ "option3 \<file>", I18N_NOOP("A long option which takes an argument"), 0 },
{ "option4 \<speed>", I18N_NOOP("A long option which takes an argument, defaulting to 9600"), "9600" },
{ "d", 0, 0 },
{ "option5", I18N_NOOP("A long option which has a short option as alias"), 0 },
{ "e", 0, 0 },
{ "nooption6", I18N_NOOP("Another long option with an alias"), 0 },
{ "f", 0, 0 },
{ "option7 \<speed>", I18N_NOOP("'--option7 speed' is the same as '-f speed'"), 0 },
{ "!option8 \<cmd>", I18N_NOOP("All options following this one will be treated as arguments"), 0 },
{ "+file", I18N_NOOP("A required argument 'file'"), 0 },
{ "+[arg1]", I18N_NOOP("An optional argument 'arg1'"), 0 },
{ "!+command", I18N_NOOP("A required argument 'command', that can contain multiple words, even starting with '-'"), 0 },
{ "", I18N_NOOP("Additional help text not associated with any particular option") 0 },
// End of options.
}
</pre>
The I18N_NOOP macro is used to indicate that these strings should be
marked for translation. The actual translation is done by TDECmdLineArgs.
You can't use i18n() here because we are setting up a static data
structure and can't do translations at compile time.
Note that a program should define the options before any arguments.
When a long option has a short option as an alias, a program should
only test for the long option.
With the above options a command line could look like:
<pre>
myapp -a -c 4800 --display localhost:0.0 --nooption5 -d /tmp/file
</pre>
Long binary options can be in the form 'option' and 'nooption'.
A command line may contain the same binary option multiple times,
the last option determines the outcome:
<pre>
myapp --nooption4 --option4 --nooption4
</pre>
is the same as:
<pre>
myapp --nooption4
</pre>
If an option value is provided multiple times, normally only the last
value is used:
<pre>
myapp -c 1200 -c 2400 -c 4800
</pre>
is usually the same as:
<pre>
myapp -c 4800
</pre>
However, an application can choose to use all values specified as well.
As an example of this, consider that you may wish to specify a
number of directories to use:
<pre>
myapp -I /usr/include -I /opt/kde/include -I /usr/X11/include
</pre>
When an application does this it should mention this in the description
of the option. To access these options, use getOptionList()
Tips for end-users:
<li>
Single char options like "-a -b -c" may be combined into "-abc"
</li>
<li>
The option "--foo bar" may also be written "--foo=bar"
</li>
<li>
The option "-P lp1" may also be written "-P=lp1" or "-Plp1"
</li>
<li>
The option "--foo bar" may also be written "-foo bar"
</li>

/**
Add options to your application.
You must make sure that all possible options have been added before
any class uses the command line arguments.
The list of options should look like this:
<pre>
static String[][] options =
{
{ "option1 \<argument>", I18N_NOOP("Description 1"), "my_extra_arg" },
{ "o", 0, 0 },
{ "option2", I18N_NOOP("Description 2"), 0 },
{ "nooption3", I18N_NOOP("Description 3"), 0 },
}
</pre>
<li>
"option1" is an option that requires an additional argument,
but if one is not provided, it uses "my_extra_arg".
</li>
<li>
"option2" is an option that can be turned on. The default is off.
</li>
<li>
"option3" is an option that can be turned off. The default is on.
</li>
<li>
"o" does not have a description. It is an alias for the option
that follows. In this case "option2".
</li>
<li>
"+file" specifies an argument. The '+' is removed. If your program
doesn't specify that it can use arguments your program will abort
when an argument is passed to it. Note that the reverse is not
true. If required, you must check yourself the number of arguments
specified by the user:
<pre>
TDECmdLineArgs args = TDECmdLineArgs.parsedArgs();
if (args.count() == 0) TDECmdLineArgs.usage(i18n("No file specified!"));
</pre>
</li>
In BNF:
<pre>
cmd = myapp [options] file
options = (option)
option = --option1 \<argument> |
(-o | --option2 | --nooption2) |
( --option3 | --nooption3 )
</pre>
Instead of "--option3" one may also use "-option3"
Usage examples:
<li>
"myapp --option1 test"
</li>
<li>
"myapp" (same as "myapp --option1 my_extra_arg")
</li>
<li>
"myapp --option2"
</li>
<li>
"myapp --nooption2" (same as "myapp", since it is off by default)
</li>
<li>
"myapp -o" (same as "myapp --option2")
</li>
<li>
"myapp --nooption3"
</li>
<li>
"myapp --option3 (same as "myapp", since it is on by default)
</li>
<li>
"myapp --option2 --nooption2" (same as "myapp", because it
option2 is off by default, and the last usage applies)
</li>
<li>
"myapp /tmp/file"
</li>
