NAME

Perl::Tidy::Sweetened::Keyword::Block - Perl::Tidy::Sweetened filter plugin to define new subroutine and class keywords

VERSION

version 0.23

SYNOPSIS

our $plugins = Perl::Tidy::Sweetened::Pluggable->new();

$plugins->add_filter(
    Perl::Tidy::Sweetened::Keyword::Block->new(
        keyword    => 'method',
        marker     => 'METHOD',
        replacment => 'sub',
        clauses    => [ 'PAREN?', '(returns \s* PAREN)?' ],
    ) );

DESCRIPTION

This is a Perl::Tidy::Sweetened filter which enables the definition of arbitrary keywords for subroutines with any number of potential signature definitions. New accepts:

keyword

keyword => 'method'

Declares a new keyword (in this example the "method" keyword).

marker

marker => 'METHOD'

Provides a text marker to be used to flag the new keywords during prefilter. The source code will be filtered prior to formatting by Perl::Tidy such that:

method foo {
}

is turned into:

sub foo { # __METHOD 1
}

replacement

replacement => 'sub'

Will convert the keyword to a sub as shown above.

clauses

clauses => [ 'PAREN?' ]

Provides a list of strings which will be turned into a regex to capture additional clauses. The regex will include the 'xm' flags (so be sure to escape spaces). The clause can be marked optional with '?'. The special text "PAREN" can be used to capture a balanced parenthetical.

This example will capture a parameter list enclosed by parenthesis, ie:

method foo (Int $i) {
}

No formatting is done on the clauses at this time. The order of declaration is significant.
