14 # - LOG_LEVEL_CGI, LOG_LEVEL_ERROR, LOG_LEVEL_WRITE content highlighting
15 # - create fancy statistics
16 # - grep through Privoxy sources to find unsupported log messages
17 # - hunt down substitutions that match content from variables which
18 # can contain stuff like ()?'[]
19 # - replace $h{'foo'} with h('foo') where possible
20 # - hunt down XXX comments instead of just creating them
21 # - add example log lines for every regex and mark them up for
23 # - Handle incomplete input without Perl warning about undefined variables.
24 # - Use generic highlighting function that takes a regex and the
26 # - Add --compress and --decompress options.

2557 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2558 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2559 will hide the "filter foo caused 0 hits" message.
2563 [B<--accept-unknown-messages>] Don't print warnings in case of unknown messages,
2564 just don't highlight them.
2566 [B<--host-statistics-threshold>] Only show the request count for a host
2567 if it's above or equal to the given threshold. If the threshold is 0, host
2568 statistics are disabled.
2570 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
2571 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2572 This option is only intended to make embedding log excerpts in web pages easier.
2573 It does not escape any input!
2575 [B<--no-msecs>] Don't expect milisecond resolution
2577 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2578 the filtered output is piped into less in which case the ANSI control
2579 codes don't work, or if the terminal itself doesn't support the control
2582 [B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
2583 Note that the mapping from thread ids to shortened ids is created at run-time
2584 and thus varies with the input.
2586 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2587 that didn't modify the content.
2589 [B<--statistics>] Gather various statistics instead of syntax highlighting
2590 log messages. This is an experimental feature, if the results look wrong
2591 they very well might be. Also note that the results are pretty much guaranteed
2592 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
2594 [B<--unbreak-lines-only>] Tries to fix lines that got messed up by a broken or
2595 interestingly configured mail client and thus are no longer recognized properly.
2596 Only fixes some breakage, but may be good enough or at least better than nothing.
2597 Doesn't do anything else, so you probably want to pipe the output into
2598 B<privoxy-log-parser> again.
2600 [B<--url-statistics-threshold>] Only show the request count for a resource
2601 if it's above or equal to the given threshold. If the threshold is 0, URL
2602 statistics are disabled.
2604 [B<--version>] Print version and exit.
2608 To monitor a log file:
2610 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2612 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2613 or if the log won't get rotated anyway. The log file location depends
2614 on your system (Doh!).
2616 To monitor Privoxy without having it write to a log file:
2618 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2620 Again, the config file location depends on your system. Output redirection
2621 depends on your shell, the above works with bourne shells.
2623 To read a processed Privoxy log file from top to bottom, letting the content
2624 scroll by slightly faster than you can read:
2626 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2628 This is probably only useful to fill screens in the background of haxor movies.
2632 Syntax highlighting with ANSI escape sequences will look strange
2633 if your background color isn't black.
2635 Some messages aren't recognized yet and will not be fully highlighted.
2637 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2638 using earlier Privoxy versions will probably result in an increased amount
2639 of unrecognized log lines.
2641 Privoxy's log files tend to be rather large. If you use HTML
2642 highlighting some browsers can't handle them, get confused and
2643 will eventually crash because of segmentation faults or unexpected
2644 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2649 Many settings can't be controlled through command line options yet.
