NAME¶
Pandoc::Filter::Lazy - facilitate creation of filters
SYNOPSIS¶
my $filter = Pandoc::Filter::Lazy->new( 'Header => sub { Header $_->level, [ Str $_->string ] }' ); if ( $filter->error ) { say STDERR $lazy->error; say STDERR $lazy->code; } else { $filter->apply(...) }
DESCRIPTION¶
This module helps creation of Pandoc::Filter with arguments given as string. The following should result in equivalent filters:
Pandoc::Walker::action( ... ); # ... as code Pandoc::Filter::Lazy->new( '...' ) # '...' as string
The script passed as only argument is tried to convert to valid Perl by escaping selectors and adding a missing "sub { ... }"", for instance
Code|CodeBlock => say $_->class
Is converted to
'Code|CodeBlock' => sub { say $_->class }

Return the (possibly cleaned) script arguments to create the filter.
code( [ indent => $indent, ] [ function => $function ] )¶
