807 | SQL::Translator is a group of Perl modules that converts |
808 | vendor-specific SQL table definitions into other formats, such as |
809 | other vendor-specific SQL, ER diagrams, documentation (POD and HTML), |
810 | XML, and Class::DBI classes. The main focus of SQL::Translator is |
811 | SQL, but parsers exist for other structured data formats, including |
812 | Excel spreadsheets and arbitrarily delimited text files. Through the |
813 | separation of the code into parsers and producers with an object model |
814 | in between, it's possible to combine any parser with any producer, to |
815 | plug in custom parsers or producers, or to manipulate the parsed data |
816 | via the built-in object model. Presently only the definition parts of |
817 | SQL are handled (CREATE, ALTER), not the manipulation of data (INSERT, |
818 | UPDATE, DELETE). |

820 | =head1 CONSTRUCTOR |
821 | |
5760246d |
822 | The constructor is called C<new>, and accepts a optional hash of options. |
0f3778d0 |
823 | Valid options are: |
824 | |
825 | =over 4 |
826 | |
ca251f03 |
827 | =item * |

872 | |
873 | All options are, well, optional; these attributes can be set via |
874 | instance methods. Internally, they are; no (non-syntactical) |
875 | advantage is gained by passing options to the constructor. |
876 | |
877 | =head1 METHODS |
878 | |
5760246d |
879 | =head2 add_drop_table |
0f3778d0 |
880 | |
881 | Toggles whether or not to add "DROP TABLE" statements just before the |
882 | create definitions. |
883 | |
5760246d |
884 | =head2 no_comments |
0f3778d0 |
885 | |
886 | Toggles whether to print comments in the output. Accepts a true or false |
887 | value, returns the current value. |
888 | |
5760246d |
889 | =head2 producer |
0f3778d0 |
890 | |
5760246d |
891 | The C<producer> method is an accessor/mutator, used to retrieve or |
0f3778d0 |
892 | define what subroutine is called to produce the output. A subroutine |
893 | defined as a producer will be invoked as a function (I<not a method>) |
ca251f03 |
894 | and passed 2 parameters: its container C<SQL::Translator> instance and a |
0f3778d0 |
895 | data structure. It is expected that the function transform the data |
ca251f03 |
896 | structure to a string. The C<SQL::Transformer> instance is provided for |
0f3778d0 |
897 | informational purposes; for example, the type of the parser can be |
5760246d |
898 | retrieved using the C<parser_type> method, and the C<error> and |
899 | C<debug> methods can be called when needed. |
0f3778d0 |
900 | |
ca251f03 |
901 | When defining a producer, one of several things can be passed in: A |
5760246d |
902 | module name (e.g., C<My::Groovy::Producer>), a module name relative to |
903 | the C<SQL::Translator::Producer> namespace (e.g., C<MySQL>), a module |
ca251f03 |
904 | name and function combination (C<My::Groovy::Producer::transmogrify>), |
0f3778d0 |
905 | or a reference to an anonymous subroutine. If a full module name is |
906 | passed in (for the purposes of this method, a string containing "::" |
907 | is considered to be a module name), it is treated as a package, and a |
ca251f03 |
908 | function called "produce" will be invoked: C<$modulename::produce>. |
909 | If $modulename cannot be loaded, the final portion is stripped off and |
0f3778d0 |
910 | treated as a function. In other words, if there is no file named |
ca251f03 |
911 | F<My/Groovy/Producer/transmogrify.pm>, C<SQL::Translator> will attempt |
5760246d |
912 | to load F<My/Groovy/Producer.pm> and use C<transmogrify> as the name of |
913 | the function, instead of the default C<produce>. |
0f3778d0 |
914 | |
915 | my $tr = SQL::Translator->new; |
916 | |
917 | # This will invoke My::Groovy::Producer::produce($tr, $data) |
918 | $tr->producer("My::Groovy::Producer"); |
919 | |
920 | # This will invoke SQL::Translator::Producer::Sybase::produce($tr, $data) |
921 | $tr->producer("Sybase"); |
922 | |
923 | # This will invoke My::Groovy::Producer::transmogrify($tr, $data), |
924 | # assuming that My::Groovy::Producer::transmogrify is not a module |
925 | # on disk. |
926 | $tr->producer("My::Groovy::Producer::transmogrify"); |
927 | |
928 | # This will invoke the referenced subroutine directly, as |
929 | # $subref->($tr, $data); |
930 | $tr->producer(\&my_producer); |
931 | |
5760246d |
932 | There is also a method named C<producer_type>, which is a string |
933 | containing the classname to which the above C<produce> function |
0f3778d0 |
934 | belongs. In the case of anonymous subroutines, this method returns |
935 | the string "CODE". |
936 | |
5760246d |
937 | Finally, there is a method named C<producer_args>, which is both an |
0f3778d0 |
938 | accessor and a mutator. Arbitrary data may be stored in name => value |
939 | pairs for the producer subroutine to access: |
940 | |
941 | sub My::Random::producer { |
942 | my ($tr, $data) = @_; |
943 | my $pr_args = $tr->producer_args(); |
944 | |
945 | # $pr_args is a hashref. |
946 | |
5760246d |
947 | Extra data passed to the C<producer> method is passed to |
948 | C<producer_args>: |
0f3778d0 |
949 | |
950 | $tr->producer("xSV", delimiter => ',\s*'); |
951 | |
952 | # In SQL::Translator::Producer::xSV: |
953 | my $args = $tr->producer_args; |
954 | my $delimiter = $args->{'delimiter'}; # value is ,\s* |
955 | |
5760246d |
956 | =head2 parser |
0f3778d0 |
957 | |
5760246d |
958 | The C<parser> method defines or retrieves a subroutine that will be |
0f3778d0 |
959 | called to perform the parsing. The basic idea is the same as that of |
5760246d |
960 | C<producer> (see above), except the default subroutine name is |
ca251f03 |
961 | "parse", and will be invoked as C<$module_name::parse($tr, $data)>. |
0f3778d0 |
962 | Also, the parser subroutine will be passed a string containing the |
963 | entirety of the data to be parsed. |
964 | |
965 | # Invokes SQL::Translator::Parser::MySQL::parse() |
966 | $tr->parser("MySQL"); |
967 | |
968 | # Invokes My::Groovy::Parser::parse() |
969 | $tr->parser("My::Groovy::Parser"); |
970 | |
971 | # Invoke an anonymous subroutine directly |
972 | $tr->parser(sub { |
973 | my $dumper = Data::Dumper->new([ $_[1] ], [ "SQL" ]); |
974 | $dumper->Purity(1)->Terse(1)->Deepcopy(1); |
975 | return $dumper->Dump; |
976 | }); |
977 | |
5760246d |
978 | There is also C<parser_type> and C<parser_args>, which perform |
979 | analogously to C<producer_type> and C<producer_args> |
0f3778d0 |
980 | |
5760246d |
981 | =head2 show_warnings |
0f3778d0 |
982 | |
983 | Toggles whether to print warnings of name conflicts, identifier |
984 | mutations, etc. Probably only generated by producers to let the user |
985 | know when something won't translate very smoothly (e.g., MySQL "enum" |
986 | fields into Oracle). Accepts a true or false value, returns the |
987 | current value. |
988 | |
5760246d |
989 | =head2 translate |
0f3778d0 |
990 | |
5760246d |
991 | The C<translate> method calls the subroutines referenced by the |
992 | C<parser> and C<producer> data members (described above). It accepts |
0f3778d0 |
993 | as arguments a number of things, in key => value format, including |
994 | (potentially) a parser and a producer (they are passed directly to the |
5760246d |
995 | C<parser> and C<producer> methods). |
0f3778d0 |
996 | |
5760246d |
997 | Here is how the parameter list to C<translate> is parsed: |
0f3778d0 |
998 | |
999 | =over |
1000 | |
1001 | =item * |
1002 | |
1003 | 1 argument means it's the data to be parsed; which could be a string |
ca251f03 |
1004 | (filename) or a reference to a scalar (a string stored in memory), or a |
0f3778d0 |
1005 | reference to a hash, which is parsed as being more than one argument |
1006 | (see next section). |
1007 | |
1008 | # Parse the file /path/to/datafile |
1009 | my $output = $tr->translate("/path/to/datafile"); |
1010 | |
1011 | # Parse the data contained in the string $data |
1012 | my $output = $tr->translate(\$data); |
1013 | |
1014 | =item * |
1015 | |
1016 | More than 1 argument means its a hash of things, and it might be |
1017 | setting a parser, producer, or datasource (this key is named |
1018 | "filename" or "file" if it's a file, or "data" for a SCALAR reference. |
1019 | |
1020 | # As above, parse /path/to/datafile, but with different producers |
1021 | for my $prod ("MySQL", "XML", "Sybase") { |
1022 | print $tr->translate( |
1023 | producer => $prod, |
1024 | filename => "/path/to/datafile", |
1025 | ); |
1026 | } |
1027 | |
1028 | # The filename hash key could also be: |
1029 | datasource => \$data, |
1030 | |
1031 | You get the idea. |
1032 | |
1033 | =back |
1034 | |
5760246d |
1035 | =head2 filename, data |
0f3778d0 |
1036 | |
5760246d |
1037 | Using the C<filename> method, the filename of the data to be parsed |
1038 | can be set. This method can be used in conjunction with the C<data> |
1039 | method, below. If both the C<filename> and C<data> methods are |
1040 | invoked as mutators, the data set in the C<data> method is used. |
0f3778d0 |
1041 | |
1042 | $tr->filename("/my/data/files/create.sql"); |
1043 | |
1044 | or: |
1045 | |
1046 | my $create_script = do { |
1047 | local $/; |
1048 | open CREATE, "/my/data/files/create.sql" or die $!; |
1049 | <CREATE>; |
1050 | }; |
1051 | $tr->data(\$create_script); |
1052 | |
5760246d |
1053 | C<filename> takes a string, which is interpreted as a filename. |
1054 | C<data> takes a reference to a string, which is used as the data to be |
0f3778d0 |
1055 | parsed. If a filename is set, then that file is opened and read when |
5760246d |
1056 | the C<translate> method is called, as long as the data instance |
0f3778d0 |
1057 | variable is not set. |
1058 | |
45ee6be0 |
1059 | =head2 schema |
1060 | |
1061 | Returns the SQL::Translator::Schema object. |
1062 | |
5760246d |
1063 | =head2 trace |
0f3778d0 |
1064 | |
1065 | Turns on/off the tracing option of Parse::RecDescent. |
1066 | |
389b318c |
1067 | =head2 validate |
1068 | |
1069 | Whether or not to validate the schema object after parsing and before |
1070 | producing. |
