110 | The following code excerpt is a minimal decoder program. It reads all |

|

203 | |

204 | Initialize is automatically called when the module is loaded and allocates |

205 | quite a small amount of memory for todays machines ;) CleanUp releases that |
|
|
206 | again. |
|
|
207 | |
|
|
208 | On my machine, a fairly complete decode with DBI backend needs about 10MB |
|

209 | RSS to decode 20000 files. |

265 | with the given id, and if C<$delflag> is true, delete the file after it |

266 | is no longer necessary. If you are certain of the part number, you can |
|
|
267 | specify it as the last argument. |
|

268 | |

269 | A better (usually faster) way of doing this is using the C<SetFNameFilter> |

|
|
275 | values, beginning at C<0>, to try to merge parts that usually would not |
|
|
276 | have been merged. |
|
|
277 | |
|
|
278 | Most probably this will result in garbled files, so never do this by |

284 | C<undef> of no file with that number exists. |
|
|
285 | |
|
|
286 | The first file has number C<0>, and the series has no holes, so you can |
|
|
287 | iterate over all files by starting with zero and incrementing until you |
|

288 | hit C<undef>. |

|
404 | two arguments, the subject line and the current candidate for the |
|
|
405 | filename. The latter argument can be C<undef>, which means that no |
|
|
406 | filename could be found (and likely no one exists, so it is safe to also |
|
|
407 | return C<undef> in this case). If it doesn't return anything (not even |
|
|
408 | C<undef>!), then nothing happens, so this is a no-op callback: |
|
|
409 | |
|
|
410 | sub cb { |
|
|
411 | return (); |
|
|
412 | } |
|
|
413 | |
|
|
414 | If it returns C<undef>, then this indicates that no filename could be |
|
|
415 | found. In all other cases, the return value is taken to be the filename. |
|
|
416 | |
|
|
417 | This is a slightly more useful callback: |
|
|
418 | |
|
|
419 | sub cb { |
|
|
420 | return unless $_[1]; # skip "Re:"-plies et al. |
|
|
421 | my ($subject, $filename) = @_; |
|
|
422 | # if we find some *.rar, take it |
|
|
423 | return $1 if $subject =~ /(\w+\.rar)/; |
|
|
424 | # otherwise just pass what we have |
|
|
425 | return (); |
