You can use the Marpa parser:
#!/usr/bin/perl use strict; use warnings; use Data::Dumper; use Marpa::R2; my $g = << '__G__'; lexeme default = latm => 1 :start ::= Hash :default ::= action => itself Hash ::= '(' Pairs ')' action => hash Pairs ::= Pair+ action => pairs Pair ::= '(' Key Value ')' action => pair Key ::= String Value ::= String | Pairs String ~ [^\s()]+ whitespace ~ [\s]+ :discard ~ whitespace __G__ my $grammar = 'Marpa::R2::Scanless::G'->new({ source => \$g }); my $input = '( (SECTION (Section_KEY Value1) (Another_KEY1 Value2) (KEY2 value3) (KEY3 Value4)) (NEW_SECTION (SUB_SECTION (KEY4 Value5)) (NEW_SUB_SECTION (KEY5 Value6) ) ) )'; my $recce = 'Marpa::R2::Scanless::R'->new({ grammar => $gram +mar, semantics_package => 'main +', }); $recce->read(\$input); print Dumper $recce->value; sub hash { $_[2] } sub pairs { shift; +{ map @$_, @_ } } sub pair { [ @_[2, 3] ] } sub itself { $_[1] }


$VAR1 = \{ 'SECTION' => { 'Section_KEY' => 'Value1', 'KEY2' => 'value3', 'Another_KEY1' => 'Value2', 'KEY3' => 'Value4' }, 'NEW_SECTION' => { 'NEW_SUB_SECTION' => { 'KEY5' => 'Value +6' }, 'SUB_SECTION' => { 'KEY4' => 'Value5' } } };
