Strings

Examples

Portable Presenter is a package designed to give presentations. The presentation is written in Perl/Tk. Perl is a weird language, and that's an understatement: there are a few hundred ways to denote your information.

Basically, writing a presentation with PPresenter is writing option-lists. On this page, I show a few ways how to denote these option-lists.

Examples

Now a few alternatives which each produce exactly the same result. 
1.  $show->addSlide(-title   => 'my first show',
                    -reqtime => 30,
                    -text    => "These are two\nlines of text\n");
is equivalent to 
2.  $show->addSlide('-title', 'my first show',
                    '-reqtime', 30,
                    '-text', 'These are two
    lines of text
    ');
is equivalent to 
3.  $show->addSlide
        ( -title     => "my first show"
        , -reqtime   => '30'
        , -text      => <<TEXT
    These are two
    lines of text
    TEXT
        );
is equivalent to 
4.  $show->addSlide(
        -title     => "my first show",
        -reqtime   => 30,
        -text      => <<TEXT);
    These are two
    lines of text
    TEXT
is equivalent to 
5.  my @x = ( -title => "my first show", -reqtime => 30, '-text');
    $show->addSlide(@x, <<TEXT);
    These are two
    lines of text
    TEXT
Perl is a weird language... Be very careful with the comma's and semi-colons in relation to here-documents. I prefer the third notation, but this is just a very personal decission, which I violate myself whenever I like.
