pod::elemental::selectors
Pod::Elemental::Selectors(3pm) User Contributed Perl Documentation Pod::Elemental::Selectors(3pm)NAME
Pod::Elemental::Selectors - predicates for selecting elements
VERSION
version 0.102362
OVERVIEW
Pod::Elemental::Selectors provides a number of routines to check for Pod::Elemental paragraphs with given qualities.
SELECTORS
Selectors are predicates: they examine paragraphs and return either true or false. All the selectors have (by default) names like:
"s_whatever". They expect zero or more parameters to affect the selection. If these parameters are given, but no paragraph, a callback
will be returned that will expect a paragraph. If a paragraph is given, the selector will return immediately.
For example, the "s_command" selector expects a parameter that can be the name of the command desired. Both of the following uses are
valid:
# create and use a callback:
my $selector = s_command('head1');
my @headers = grep { $selector->($_) } @paragraphs;
# just check a paragraph right now:
if ( s_command('head1', $paragraph) ) { ... }
The selectors can be imported individually or as the "-all" group, and can be renamed with Sub::Exporter features. (Selectors cannot yet
be curried by Sub::Exporter.)
s_blank
my $callback = s_blank;
if( s_blank($para) ) { ... }
"s_blank" tests whether a paragraph is a Generic::Blank element.
s_flat
my $callback = s_flat;
if( s_flat($para) ) { ... }
"s_flat" tests whether a paragraph does Pod::Elemental::Flat -- in other words, is content-only.
s_node
my $callback = s_node;
if( s_node($para) ) { ... }
"s_node" tests whether a paragraph does Pod::Elemental::Node -- in other words, whether it may have children.
s_command
my $callback = s_command;
my $callback = s_command( $command_name);
my $callback = s_command(@command_names);
if( s_command(undef, $para) ) { ... }
if( s_command( $command_name, $para) ) { ... }
if( s_command(@command_names, $para) ) { ... }
"s_command" tests whether a paragraph does Pod::Elemental::Command. If a command name (or a reference to an array of command names) is
given, the tested paragraph's command must match one of the given command names.
