, which is the current 
| 51 |  |  |  |  |  |  | L table we are producing, | 
| 52 |  |  |  |  |  |  | which you can then use to walk the schema via the methods documented | 
| 53 |  |  |  |  |  |  | in that module. You also get C as a shortcut to the | 
| 54 |  |  |  |  |  |  | L for the table and C, | 
| 55 |  |  |  |  |  |  | the L object for this parse in case you want to get | 
| 56 |  |  |  |  |  |  | access to any of the options etc set here. | 
| 57 |  |  |  |  |  |  |  | 
| 58 |  |  |  |  |  |  | Here's a brief example of what the template could look like: | 
| 59 |  |  |  |  |  |  |  | 
| 60 |  |  |  |  |  |  | [% table.name %] | 
| 61 |  |  |  |  |  |  | ================ | 
| 62 |  |  |  |  |  |  | [% FOREACH field = table.get_fields %] | 
| 63 |  |  |  |  |  |  | [% field.name %]   [% field.data_type %]([% field.size %]) | 
| 64 |  |  |  |  |  |  | [% END -%] | 
| 65 |  |  |  |  |  |  |  | 
| 66 |  |  |  |  |  |  | See F for a more complete example. | 
| 67 |  |  |  |  |  |  |  | 
| 68 |  |  |  |  |  |  | You can also set any of the options used to initialize the Template | 
| 69 |  |  |  |  |  |  | object by adding them to your producer_args. See Template Toolkit docs | 
| 70 |  |  |  |  |  |  | for details of the options. | 
| 71 |  |  |  |  |  |  |  | 
| 72 |  |  |  |  |  |  | $translator          = SQL::Translator->new( | 
| 73 |  |  |  |  |  |  | to               => 'TT', | 
| 74 |  |  |  |  |  |  | producer_args    => { | 
| 75 |  |  |  |  |  |  | ttfile       => 'foo_template.tt', | 
| 76 |  |  |  |  |  |  | INCLUDE_PATH => '/foo/templates/tt', | 
| 77 |  |  |  |  |  |  | INTERPOLATE  => 1, | 
| 78 |  |  |  |  |  |  | }, | 
| 79 |  |  |  |  |  |  | ); | 
| 80 |  |  |  |  |  |  |  | 
| 81 |  |  |  |  |  |  | If you set C and its additional options the producer will | 
| 82 |  |  |  |  |  |  | write a separate file for each table in the schema. This is useful for | 
| 83 |  |  |  |  |  |  | producing things like HTML documentation where every table gets its | 
| 84 |  |  |  |  |  |  | own page (you could also use TTSchema producer to add an index page). | 
| 85 |  |  |  |  |  |  | It's also particularly good for code generation where you want to | 
| 86 |  |  |  |  |  |  | produce a class file per table. |

| 92 |  |  |  |  |  |  | =item tt_table | 
| 93 |  |  |  |  |  |  |  | 
| 94 |  |  |  |  |  |  | File name of the template to run for each table. | 
| 95 |  |  |  |  |  |  |  | 
| 96 |  |  |  |  |  |  | =item mk_files | 
| 97 |  |  |  |  |  |  |  | 
| 98 |  |  |  |  |  |  | Set to true to output a file for each table in the schema (as well as | 
| 99 |  |  |  |  |  |  | returning the whole lot back to the Translalor and hence STDOUT). The | 
| 100 |  |  |  |  |  |  | file will be named after the table, with the optional C | 
| 101 |  |  |  |  |  |  | added and placed in the directory C. | 
| 102 |  |  |  |  |  |  |  | 
| 103 |  |  |  |  |  |  | =item mk_files_ext | 
| 104 |  |  |  |  |  |  |  | 
| 105 |  |  |  |  |  |  | Extension (without the dot) to add to the filename when using mk_files. | 
| 106 |  |  |  |  |  |  |  | 
| 107 |  |  |  |  |  |  | =item mk_files_base = DIR | 
| 108 |  |  |  |  |  |  |  | 
| 109 |  |  |  |  |  |  | Dir to build the table files into when using mk_files. Defaults to the | 
| 110 |  |  |  |  |  |  | current directory. | 
| 111 |  |  |  |  |  |  |  | 
| 112 |  |  |  |  |  |  | =item mk_file_dir | 
| 113 |  |  |  |  |  |  |  | 
| 114 |  |  |  |  |  |  | Set true and if the file needs to written to a directory that doesn't | 
| 115 |  |  |  |  |  |  | exist, it will be created first. | 
| 116 |  |  |  |  |  |  |  | 
| 117 |  |  |  |  |  |  | =item on_exists [Default:replace] | 
| 118 |  |  |  |  |  |  |  | 
| 119 |  |  |  |  |  |  | What to do if we are running with mk_files and a file already exists | 
| 120 |  |  |  |  |  |  | where we want to write our output. One of "skip", "die", "replace", | 
| 121 |  |  |  |  |  |  | "insert".  The default is die. | 
| 122 |  |  |  |  |  |  |  | 
| 123 |  |  |  |  |  |  | B - Over-write the existing file with the new one, clobbering | 
| 124 |  |  |  |  |  |  | anything already there. | 
| 125 |  |  |  |  |  |  |  | 
| 126 |  |  |  |  |  |  | B - Leave the original file as it was and don't write the new | 
| 127 |  |  |  |  |  |  | version anywhere. | 
| 128 |  |  |  |  |  |  |  | 
| 129 |  |  |  |  |  |  | B - Die with an existing file error. | 
| 130 |  |  |  |  |  |  |  | 
| 131 |  |  |  |  |  |  | B - Insert the generated output into the file between a set of | 
| 132 |  |  |  |  |  |  | special comments (defined by the following options.) Any code between | 
| 133 |  |  |  |  |  |  | the comments will be overwritten (ie the results from a previous | 
| 134 |  |  |  |  |  |  | produce) but the rest of the file is left alone (your custom code). | 
| 135 |  |  |  |  |  |  | This is particularly useful for code generation as it allows you to | 
| 136 |  |  |  |  |  |  | generate schema derived code and then add your own custom code | 
| 137 |  |  |  |  |  |  | to the file.  Then when the schema changes you just re-produce to | 
| 138 |  |  |  |  |  |  | insert the new code. | 
| 139 |  |  |  |  |  |  |  | 
| 140 |  |  |  |  |  |  | =item insert_comment_start | 
| 141 |  |  |  |  |  |  |  | 
| 142 |  |  |  |  |  |  | The comment to look for in the file when on_exists is C. Default | 
| 143 |  |  |  |  |  |  | is C. Must appear on it own line, with only | 
| 144 |  |  |  |  |  |  | whitespace either side, to be recognised. | 
| 145 |  |  |  |  |  |  |  | 
| 146 |  |  |  |  |  |  | =item insert_comment_end | 
| 147 |  |  |  |  |  |  |  | 
| 148 |  |  |  |  |  |  | The end comment to look for in the file when on_exists is C. | 
| 149 |  |  |  |  |  |  | Default is C. Must appear on it own line, with only | 
| 150 |  |  |  |  |  |  | whitespace either side, to be recognised. |
