20 # - hunt down XXX comments instead of just creating them
21 # - add example log lines for every regex and mark them up for

2266 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2270 B<privoxy-log-parser> [B<--accept-unknown-messages>] [B<--html-output>]
2271 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--show-ineffective-filters>]
2276 B<privoxy-log-parser> reads Privoxy log messages and
2278 - syntax-highlights recognized lines,
2280 - reformats some of them for easier comprehension,
2282 - filters out less useful messages, and
2284 - (in some cases) calculates additional information,
2285 like the compression ratio or how a filter affected
2288 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
2289 without getting confused by the resulting amount of output. For example for
2290 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2291 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2292 will hide the "filter foo caused 0 hits" message.
2296 [B<--accept-unknown-messages>] Don't print warnings in case of unknown messages,
2297 just don't highlight them.
2299 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
2300 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2301 This option is only intended to make embedding log excerpts in web pages easier.
2302 It does not escape any input!
2304 [B<--no-msecs>] Don't expect milisecond resolution
2306 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2307 the filtered output is piped into less in which case the ANSI control
2308 codes don't work, or if the terminal itself doesn't support the control
2311 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2312 that didn't modify the content.
2314 [B<--statistics>] Gather various statistics instead of syntax highlighting
2315 log messages. This is an experimental feature, if the results look wrong
2316 they very well might be. Also note that the results are pretty much guaranteed
2317 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
2319 [B<--version>] Print version and exit.
2323 To monitor a log file:
2325 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2327 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2328 or if the log won't get rotated anyway. The log file location depends
2329 on your system (Doh!).
2331 To monitor Privoxy without having it write to a log file:
2333 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2335 Again, the config file location depends on your system. Output redirection
2336 depends on your shell, the above works with bourne shells.
2338 To read a processed Privoxy log file from top to bottom, letting the content
2339 scroll by slightly faster than you can read:
2341 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2343 This is probably only useful to fill screens in the background of haxor movies.
2347 Syntax highlighting with ANSI escape sequences will look strange
2348 if your background color isn't black.
2350 Some messages aren't recognized yet and will not be fully highlighted.
2352 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2353 using earlier Privoxy versions will probably result in an increased amount
2354 of unrecognized log lines.
2356 Privoxy's log files tend to be rather large. If you use HTML
2357 highlighting some browsers can't handle them, get confused and
2358 will eventually crash because of segmentation faults or unexpected
2359 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2364 Many settings can't be controlled through command line options yet.
