509 | ||
510 | Furthermore you need access to a news server to actually post FAQs. | |
511 | ||
512 | =head1 DESCRIPTION | |
513 | ||
514 | B<yapfaq> posts (one or more) FAQs to Usenet with a certain posting | |
515 | frequency (every n days, weeks, months or years), adding all necessary | |
516 | headers as defined in its config file (by default F<yapfaq.cfg>). | |
517 | ||
518 | =head2 Configuration | |
519 | ||
520 | F<yapfaq.cfg> consists of one or more blocks, separated by C<=====> on | |
521 | a single line, each containing the configuration for one FAQ as a set | |
522 | of definitions in the form of I<param = value>. | |
523 | ||
524 | =over 4 | |
525 | ||
526 | =item B<Name> = I<project name> | |
527 | ||
528 | A name referring to your FAQ, also used for generation of a Message-ID. | |
529 | ||
530 | This value must be set. | |
531 | ||
532 | =item B<File> = I<file name> | |
533 | ||
534 | A file containing the message body of your FAQ and all pseudo headers | |
535 | (subheaders in the news.answers style). | |
536 | ||
537 | This value must be set. | |
538 | ||
539 | =item B<Posting-frequency> = I<time period> | |
540 | ||
541 | The posting frequency defines how often your FAQ will be posted. | |
542 | B<yapfaq> will only post your FAQ if this period of time has passed | |
543 | since the last posting. | |
544 | ||
545 | You can declare that time period either in I<B<d>ays> or I<B<w>weeks> | |
546 | or I<B<m>onths> or I<B<y>ears>. | |
547 | ||
548 | This value must be set. | |
549 | ||
550 | =item B<Expires> = I<time period> | |
551 | ||
552 | The period of time after which your message will expire. An Expires | |
553 | header will be calculated adding this time period to today's date. | |
554 | ||
555 | You can declare this time period either in I<B<d>ays> or I<B<w>weeks> | |
556 | or I<B<m>onths> or I<B<y>ears>. | |
557 | ||
558 | This setting is optional; the default is 3 months. | |
559 | ||
560 | =item B<From> = I<author> | |
561 | ||
562 | The author of your FAQ as it will appear in the From header of the | |
563 | message. | |
564 | ||
565 | This value must be set. | |
566 | ||
567 | =item B<Subject> = I<subject> | |
568 | ||
569 | The title of your FAQ as it will appear in the Subject header of the | |
570 | message. | |
571 | ||
572 | You may use the special string C<%LM> which will be replaced with | |
573 | the contents of the Last-Modified subheader in your I<File>. | |
574 | ||
575 | This value must be set. | |
576 | ||
577 | =item B<NGs> = I<newsgroups> | |
578 | ||
579 | A comma-separated list of newsgroup(s) to post your FAQ to as it will | |
580 | appear in the Newsgroups header of the message. | |
581 | ||
582 | This value must be set. | |
583 | ||
584 | =item B<Fup2> = I<newsgroup | poster> | |
585 | ||
586 | A comma-separated list of newsgroup(s) or the special string I<poster> | |
587 | as it will appear in the Followup-To header of the message. | |
588 | ||
589 | This setting is optional. | |
590 | ||
591 | =item B<MID-Format> = I<pattern> | |
592 | ||
593 | A pattern from which the message ID is generated as it will appear in | |
594 | the Message-ID header of the message. | |
595 | ||
596 | You may use the special strings C<%n> for the I<Name> of your project, | |
597 | C<%d> for the date the message is posted, C<%m> for the month and | |
598 | C<%y> for the year, respectively. | |
599 | ||
600 | This value must be set. | |
601 | ||
602 | =item B<Supersede> = I<yes> | |
603 | ||
604 | Add Supersedes header to the message containing the Message-ID header | |
605 | of the last posting. | |
606 | ||
607 | This setting is optional; you should set it to yes or leave it out. | |
608 | ||
609 | =item B<ExtraHeader> = I<additional headers> | |
610 | ||
611 | The contents of I<ExtraHeader> is added verbatim to the headers of | |
612 | your message so you can add custom headers like Approved. | |
613 | ||
614 | This setting is optional. | |

618 | =head2 Example configuration file | |
619 | ||
620 | # name of your project | |
621 | Name = 'testpost' | |
622 | ||
623 | # file to post (complete body and pseudo-headers) | |
624 | # ($File.cfg contains data on last posting and last MID) | |
625 | File = 'test.txt' | |
626 | ||
627 | # how often your project should be posted | |
628 | # use (d)ay OR (w)eek OR (m)onth OR (y)ear | |
629 | Posting-frequency = '1d' | |
630 | ||
631 | # time period after which the posting should expire | |
632 | # use (d)ay OR (w)eek OR (m)onth OR (y)ear | |
633 | Expires = '3m' | |
634 | ||
635 | # header "From:" | |
636 | From = 'test@domain.invalid' | |
637 | ||
638 | # header "Subject:" | |

640 | # Last-Modified pseudo header). | |
641 | Subject = 'test noreply ignore' | |
642 | ||
643 | # comma-separated list of newsgroup(s) to post to | |
644 | # (header "Newsgroups:") | |
645 | NGs = 'de.test' | |
646 | ||
647 | # header "Followup-To:" | |
648 | Fup2 = 'poster' | |
649 | ||
650 | # Message-ID ("%n" is $Name) | |
651 | MID-Format = '<%n-%d.%m.%y@domain.invalid>' | |
652 | ||
653 | # Supersede last posting? | |
654 | Supersede = yes | |
655 | ||
656 | # extra headers (appended verbatim) | |
657 | # use this for custom headers like "Approved:" | |
658 | ExtraHeader = 'Approved: moderator@domain.invalid | |
659 | X-Header: Some text' | |
660 | ||
661 | # other projects may follow separated with "=====" | |
662 | ===== | |
663 | ||
664 | Name = 'othertest' | |
665 | File = 'test.txt' | |
666 | Posting-frequency = '2m' | |
667 | From = 'My Name <my.name@domain.invalid>' | |
668 | Subject = 'Test of yapfag <%LM>' | |
669 | NGs = 'de.test,de.alt.test' | |
670 | Fup2 = 'de.test' | |
671 | MID-Format = '<%n-%m.%y@domain.invalid>' | |
672 | Supersede = yes | |
673 | ||
674 | Information about the last post and about how to form message IDs for | |
675 | posts is stored in a file named F<I<project name>.cfg> which will be | |
676 | generated if it does not exist. Each of those status files will | |
677 | contain two lines, the first being the date of the last time the FAQ | |
678 | was posted and the second being the message ID of that incarnation. | |
679 | ||
680 | =head1 OPTIONS | |
681 | ||
682 | =over 3 | |
683 | ||
684 | =item B<-h> (help) | |
685 | ||
686 | Print out version and usage information on B<yapfaq> and exit. | |
687 | ||
688 | =item B<-v> (verbose) | |
689 | ||
690 | Print out status information while running to STDOUT. | |
691 | ||
692 | =item B<-p> (post unconditionally) | |
693 | ||
694 | Post (all) FAQs unconditionally ignoring the posting frequency setting. | |
695 | ||
696 | You may want to use this with the B<-f> option (see below). | |
697 | ||
698 | =item B<-d> (dry run) | |
699 | ||
700 | Start B<yapfaq> in simulation mode, i.e. don't post anything and don't | |
701 | update any status information. | |
702 | ||
703 | =item B<-t> I<newsgroup(s) | CONSOLE> (test) | |
704 | ||
705 | Don't post to the newsgroups defined in F<yqpfaq.cfg>, but to the | |
706 | newsgroups given after B<-t> as a comma-separated list or print the | |
707 | FAQs to STDOUT separated by lines of dashes if the special string | |
708 | C<CONSOLE> is given. This can be used to preview what B<yapfaq> would | |
709 | do without embarassing yourself on Usenet. The status files are not | |
710 | updated when this option is given. | |
711 | ||
712 | You may want to use this with the B<-f> option (see below). | |
713 | ||
714 | =item B<-f> I<project name> | |
715 | ||
716 | Just deal with one FAQ only. | |
717 | ||
718 | By default B<yapfaq> will work on all FAQs that are defined in | |
719 | F<yapfaq.cfg>, check whether they are due for posting and - if they | |
720 | are - post them. Consequently when the B<-p> option is set all FAQs | |
721 | will be posted unconditionally. That may not be what you want to | |
722 | achieve, so you can limit the operation of B<yapfaq> to the named FAQ | |
723 | only. | |
724 | ||
725 | =back | |
726 | ||
727 | =head1 EXAMPLES | |
728 | ||
729 | Post all FAQs that are due for posting: | |
730 | ||
731 | yapfaq | |
732 | ||
733 | Do a dry run, showing which FAQs would be posted: | |
734 | ||
735 | yapfaq -dv | |
736 | ||
737 | Do a test run and print on STDOUT what the FAQ I<myfaq> would look | |
738 | like when posted, regardless whether it is due for posting or not: | |
739 | ||
740 | yapfaq -pt CONSOLE -f myfaq | |
741 | ||
742 | Do a "real" test run and post the FAQ I<myfaq> to I<de.test>, but only | |
743 | if it is due: | |
744 | ||
745 | yapfaq -t de.test -f myfaq | |
746 | ||
747 | =head1 ENVIRONMENT | |
748 | ||
749 | There are no special environment variables used by B<yapfaq>. | |
750 | ||
751 | =head1 FILES | |
752 | ||
753 | =over 4 | |
754 | ||
755 | =item F<yapfaq.pl> | |
756 | ||
757 | The script itself. | |
758 | ||
759 | =item F<yapfaq.cfg> | |
760 | ||
761 | Configuration file for B<yapfaq>. | |
762 | ||
763 | =item F<*.cfg> | |
764 | ||
765 | Status data on FAQs. | |
766 | ||
767 | The status files will be created on successful posting if they don't | |
768 | already exist. The first line of the file will be the date of the last | |
769 | time the FAQ was posted and the second line will be the message ID of | |
770 | the last post of that FAQ. | |
