810 | SQL::Translator is a group of Perl modules that converts |

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

823 | =head1 CONSTRUCTOR |
824 | |
5760246d |
825 | The constructor is called C<new>, and accepts a optional hash of options. |
0f3778d0 |
826 | Valid options are: |
827 | |
828 | =over 4 |
829 | |
ca251f03 |
830 | =item * |
831 | |
832 | parser / from |

872 | validate |
873 | |
0f3778d0 |
874 | =back |
875 | |
876 | All options are, well, optional; these attributes can be set via |
877 | instance methods. Internally, they are; no (non-syntactical) |
878 | advantage is gained by passing options to the constructor. |
879 | |
880 | =head1 METHODS |
881 | |
5760246d |
882 | =head2 add_drop_table |
0f3778d0 |
883 | |
884 | Toggles whether or not to add "DROP TABLE" statements just before the |
885 | create definitions. |
886 | |
5760246d |
887 | =head2 no_comments |
0f3778d0 |
888 | |
889 | Toggles whether to print comments in the output. Accepts a true or false |
890 | value, returns the current value. |
891 | |
5760246d |
892 | =head2 producer |
0f3778d0 |
893 | |
5760246d |
894 | The C<producer> method is an accessor/mutator, used to retrieve or |
0f3778d0 |
895 | define what subroutine is called to produce the output. A subroutine |
896 | defined as a producer will be invoked as a function (I<not a method>) |
ca251f03 |
897 | and passed 2 parameters: its container C<SQL::Translator> instance and a |
0f3778d0 |
898 | data structure. It is expected that the function transform the data |
ca251f03 |
899 | structure to a string. The C<SQL::Transformer> instance is provided for |
0f3778d0 |
900 | informational purposes; for example, the type of the parser can be |
5760246d |
901 | retrieved using the C<parser_type> method, and the C<error> and |
902 | C<debug> methods can be called when needed. |
0f3778d0 |
903 | |
ca251f03 |
904 | When defining a producer, one of several things can be passed in: A |
5760246d |
905 | module name (e.g., C<My::Groovy::Producer>), a module name relative to |
906 | the C<SQL::Translator::Producer> namespace (e.g., C<MySQL>), a module |
ca251f03 |
907 | name and function combination (C<My::Groovy::Producer::transmogrify>), |
0f3778d0 |
908 | or a reference to an anonymous subroutine. If a full module name is |
909 | passed in (for the purposes of this method, a string containing "::" |
910 | is considered to be a module name), it is treated as a package, and a |
ca251f03 |
911 | function called "produce" will be invoked: C<$modulename::produce>. |
912 | If $modulename cannot be loaded, the final portion is stripped off and |
0f3778d0 |
913 | treated as a function. In other words, if there is no file named |
ca251f03 |
914 | F<My/Groovy/Producer/transmogrify.pm>, C<SQL::Translator> will attempt |
5760246d |
915 | to load F<My/Groovy/Producer.pm> and use C<transmogrify> as the name of |
916 | the function, instead of the default C<produce>. |
0f3778d0 |
917 | |
918 | my $tr = SQL::Translator->new; |
919 | |
920 | # This will invoke My::Groovy::Producer::produce($tr, $data) |
921 | $tr->producer("My::Groovy::Producer"); |
922 | |
923 | # This will invoke SQL::Translator::Producer::Sybase::produce($tr, $data) |
924 | $tr->producer("Sybase"); |
925 | |
926 | # This will invoke My::Groovy::Producer::transmogrify($tr, $data), |
927 | # assuming that My::Groovy::Producer::transmogrify is not a module |
928 | # on disk. |
929 | $tr->producer("My::Groovy::Producer::transmogrify"); |
930 | |
931 | # This will invoke the referenced subroutine directly, as |
932 | # $subref->($tr, $data); |
933 | $tr->producer(\&my_producer); |
934 | |
5760246d |
935 | There is also a method named C<producer_type>, which is a string |
936 | containing the classname to which the above C<produce> function |
0f3778d0 |
937 | belongs. In the case of anonymous subroutines, this method returns |
938 | the string "CODE". |
939 | |
5760246d |
940 | Finally, there is a method named C<producer_args>, which is both an |
0f3778d0 |
941 | accessor and a mutator. Arbitrary data may be stored in name => value |
942 | pairs for the producer subroutine to access: |
943 | |
944 | sub My::Random::producer { |
945 | my ($tr, $data) = @_; |
946 | my $pr_args = $tr->producer_args(); |
947 | |
948 | # $pr_args is a hashref. |
949 | |
5760246d |
950 | Extra data passed to the C<producer> method is passed to |
951 | C<producer_args>: |
0f3778d0 |
952 | |
953 | $tr->producer("xSV", delimiter => ',\s*'); |
954 | |
955 | # In SQL::Translator::Producer::xSV: |
956 | my $args = $tr->producer_args; |
957 | my $delimiter = $args->{'delimiter'}; # value is ,\s* |
958 | |
5760246d |
959 | =head2 parser |
0f3778d0 |
960 | |
5760246d |
961 | The C<parser> method defines or retrieves a subroutine that will be |
0f3778d0 |
962 | called to perform the parsing. The basic idea is the same as that of |
5760246d |
963 | C<producer> (see above), except the default subroutine name is |
ca251f03 |
964 | "parse", and will be invoked as C<$module_name::parse($tr, $data)>. |
0f3778d0 |
965 | Also, the parser subroutine will be passed a string containing the |
966 | entirety of the data to be parsed. |
967 | |
968 | # Invokes SQL::Translator::Parser::MySQL::parse() |
969 | $tr->parser("MySQL"); |
970 | |
971 | # Invokes My::Groovy::Parser::parse() |
972 | $tr->parser("My::Groovy::Parser"); |
973 | |
974 | # Invoke an anonymous subroutine directly |
975 | $tr->parser(sub { |
976 | my $dumper = Data::Dumper->new([ $_[1] ], [ "SQL" ]); |
977 | $dumper->Purity(1)->Terse(1)->Deepcopy(1); |
978 | return $dumper->Dump; |
979 | }); |
980 | |
5760246d |
981 | There is also C<parser_type> and C<parser_args>, which perform |
982 | analogously to C<producer_type> and C<producer_args> |
0f3778d0 |
983 | |
5760246d |
984 | =head2 show_warnings |
0f3778d0 |
985 | |
986 | Toggles whether to print warnings of name conflicts, identifier |
987 | mutations, etc. Probably only generated by producers to let the user |
988 | know when something won't translate very smoothly (e.g., MySQL "enum" |
989 | fields into Oracle). Accepts a true or false value, returns the |
990 | current value. |
991 | |
5760246d |
992 | =head2 translate |
0f3778d0 |
993 | |
5760246d |
994 | The C<translate> method calls the subroutines referenced by the |
995 | C<parser> and C<producer> data members (described above). It accepts |
0f3778d0 |
996 | as arguments a number of things, in key => value format, including |
997 | (potentially) a parser and a producer (they are passed directly to the |
5760246d |
998 | C<parser> and C<producer> methods). |
0f3778d0 |
999 | |
5760246d |
1000 | Here is how the parameter list to C<translate> is parsed: |
0f3778d0 |
1001 | |
1002 | =over |
1003 | |
1004 | =item * |
1005 | |
1006 | 1 argument means it's the data to be parsed; which could be a string |
ca251f03 |
1007 | (filename) or a reference to a scalar (a string stored in memory), or a |
0f3778d0 |
1008 | reference to a hash, which is parsed as being more than one argument |
1009 | (see next section). |
1010 | |
1011 | # Parse the file /path/to/datafile |
1012 | my $output = $tr->translate("/path/to/datafile"); |
1013 | |
1014 | # Parse the data contained in the string $data |
1015 | my $output = $tr->translate(\$data); |
1016 | |
1017 | =item * |
1018 | |
1019 | More than 1 argument means its a hash of things, and it might be |
1020 | setting a parser, producer, or datasource (this key is named |
1021 | "filename" or "file" if it's a file, or "data" for a SCALAR reference. |
1022 | |
1023 | # As above, parse /path/to/datafile, but with different producers |
1024 | for my $prod ("MySQL", "XML", "Sybase") { |
1025 | print $tr->translate( |
1026 | producer => $prod, |
1027 | filename => "/path/to/datafile", |
1028 | ); |
1029 | } |
1030 | |
1031 | # The filename hash key could also be: |
1032 | datasource => \$data, |
1033 | |
1034 | You get the idea. |
1035 | |
1036 | =back |
1037 | |
5760246d |
1038 | =head2 filename, data |
0f3778d0 |
1039 | |
5760246d |
1040 | Using the C<filename> method, the filename of the data to be parsed |
1041 | can be set. This method can be used in conjunction with the C<data> |
1042 | method, below. If both the C<filename> and C<data> methods are |
1043 | invoked as mutators, the data set in the C<data> method is used. |
0f3778d0 |
1044 | |
1045 | $tr->filename("/my/data/files/create.sql"); |
1046 | |
1047 | or: |
1048 | |
1049 | my $create_script = do { |
1050 | local $/; |
1051 | open CREATE, "/my/data/files/create.sql" or die $!; |
1052 | <CREATE>; |
1053 | }; |
1054 | $tr->data(\$create_script); |
1055 | |
5760246d |
1056 | C<filename> takes a string, which is interpreted as a filename. |
1057 | C<data> takes a reference to a string, which is used as the data to be |
0f3778d0 |
1058 | parsed. If a filename is set, then that file is opened and read when |
5760246d |
1059 | the C<translate> method is called, as long as the data instance |
0f3778d0 |
1060 | variable is not set. |
1061 | |
45ee6be0 |
1062 | =head2 schema |
1063 | |
1064 | Returns the SQL::Translator::Schema object. |
1065 | |
5760246d |
1066 | =head2 trace |
0f3778d0 |
1067 | |
1068 | Turns on/off the tracing option of Parse::RecDescent. |
1069 | |
389b318c |
1070 | =head2 validate |
1071 | |
1072 | Whether or not to validate the schema object after parsing and before |
1073 | producing. |
