=head1 NAME

OraTokenizer - A simple SQL tokenizer.

=head1 VERSION

0.20

=head1 SYNOPSIS

 use OraTokenizer qw(tokenize_sql);

 my $query= q{SELECT 1 + 1};
 my @tokens= OraTokenizer->tokenize($query);

 # @tokens now contains ('SELECT', ' ', '1', ' ', '+', ' ', '1')

 @tokens= tokenize_sql($query); # procedural interface

=head1 DESCRIPTION

OraTokenizer is a simple tokenizer for SQL queries. It does not claim to be
a parser or query verifier. It just creates sane tokens from a valid SQL
query.

It supports SQL with comments like:

 -- This query is used to insert a message into
 -- logs table
 INSERT INTO log (application, message) VALUES (?, ?)

Also supports C<''>, C<""> and C<\'> escaping methods, so tokenizing queries
like the one below should not be a problem:

 INSERT INTO log (application, message)
 VALUES ('myapp', 'Hey, this is a ''single quoted string''!')

=head1 API

=over 4

=item tokenize_sql

 use OraTokenizer qw(tokenize_sql);

 my @tokens= tokenize_sql($query);
 my $tokens= tokenize_sql($query);

 $tokens= tokenize_sql( $query, $remove_white_tokens );

C<tokenize_sql> can be imported to current namespace on request. It receives a
SQL query, and returns an array of tokens if called in list context, or an
arrayref if called in scalar context.

=item tokenize

 my @tokens= OraTokenizer->tokenize($query);
 my $tokens= OraTokenizer->tokenize($query);

 $tokens= OraTokenizer->tokenize( $query, $remove_white_tokens );

This is the only available class method. It receives a SQL query, and returns an
array of tokens if called in list context, or an arrayref if called in scalar
context.

If C<$remove_white_tokens> is true, white spaces only tokens will be removed from
result.

=head1 NAME

OraBeautify - Beautify SQL statements by adding line breaks indentation

=head1 SYNOPSIS

	my $sql = OraBeautify->new;

	$sql->query($sql_query);

	my $nice_sql = $sql->beautify;

=head1 DESCRIPTION

Beautifies SQL statements by adding line breaks indentation.

=head1 METHODS

=over 4

=item B<new>(query => '', spaces => 4, space => ' ', break => "\n", wrap => {})

Constructor. Takes a few options.

=over 4

=item B<query> => ''

Initialize the instance with a SQL string. Defaults to an empty string.

=item B<spaces> => 4

Number of spaces that make one indentation level. Defaults to 4.

=item B<space> => ' '

A string that is used as space. Default is an ASCII space character.

=item B<break> => "\n"

String that is used for linebreaks. Default is "\n".

=item B<wrap> => {}

Use this if you want to surround certain tokens with markup stuff. Known token
types are "keywords" and "constants" for now. The value of each token type
should be an array with two elements, one that is placed before the token and
one that is placed behind it. For example, use make keywords red using terminal
color escape sequences.

	{ keywords => [ "\x1B[0;31m", "\x1B[0m" ] }

=item B<uc_keywords> => 1|0

When true (1) all SQL keywords will be uppercased in output.  Default is false (0).

=back

=item B<add>($more_sql)

Appends another chunk of SQL.

=item B<query>($query)

Sets the query to the new query string. Overwrites anything that was added with
prior calls to B<query> or B<add>.

=item B<beautify>

Beautifies the internally saved SQL string and returns the result.

=item B<add_keywords>($keyword, $another_keyword, \@more_keywords)

Add any amount of keywords of arrays of keywords to highlight.

=item B<add_rule>($rule, $token)

Add a custom formatting rule. The first argument is the rule, a string
containing one or more commands (explained below), separated by dashes. The
second argument may be either a token (string) or a list of strings. Tokens are
grouped by rules internally, so you may call this method multiple times with
the same rule string and different tokens, and the rule will apply to all of
the tokens.

The following formatting commands are known at the moment:

=over 4

=item B<token> - insert the token this rule applies to

=item B<over> - increase indentation level

=item B<back> - decrease indentation level

=item B<break> - insert line break

=item B<push> - push current indentation level to an internal stack

=item B<pop> - restore last indentation level from the stack

=item B<reset> - reset internal indentation level stack

=back

B<push>, B<pop> and B<reset> should be rarely needed.


B<NOTE>:
Custom rules override default rules. Some default rules do things that
can't be done using custom rules, such as changing the format of a token
depending on the last or next token.


B<NOTE>:
I'm trying to provide sane default rules. If you find that a custom
rule of yours would make more sense as a default rule, please create a ticket.


=back

=head1 BUGS

Needs more tests.

Please report bugs in the CPAN bug tracker.

This module is not complete (known SQL keywords, special formatting of
keywords), so if you want see something added, just send me a patch.
