"""GUI interface to webchecker.
|
||||
|
||||
This works as a Grail applet too! E.g.
|
||||
|
||||
<APPLET CODE=wcgui.py NAME=CheckerWindow>
|
||||
<PARAM NAME=roots VALUE="http://<yourfavoritehost>">
|
||||
</APPLET>
|
||||
|
||||
Checkpoints are not (yet?) supported.
|
||||
|
||||
User interface:
|
||||
|
||||
When the 'Go' checkbutton is checked, web pages will be checked, one
|
||||
at a time in the Tk 'idle' time. The other checkbuttons determine
|
||||
whether the corresponding output panel is shown. There are six
|
||||
panels:
|
||||
|
||||
Log -- raw output from the checker (-v, -q affect this)
|
||||
To check -- local links discovered but not yet checked
|
||||
Off site -- links discovered that point off site
|
||||
Checked -- local links that have been checked
|
||||
Bad links -- links that failed upon checking
|
||||
Details -- details about one URL; double click on a URL in any of
|
||||
the aboce list panels (not in Log) will show that URL
|
||||
|
||||
XXX There ought to be a list of pages known to contain at least one
|
||||
bad link.
|
||||
|
||||
Use your window manager's Close command to quit.
|
||||
|
||||
Command line options:
|
||||
|
||||
-m bytes -- skip HTML pages larger than this size (default %(MAXPAGE)d)
|
||||
-n -- reports only, no checking (use with -R)
|
||||
-q -- quiet operation (also suppresses external links report)
|
||||
-v -- verbose operation; repeating -v will increase verbosity
|
||||
-x -- check external links (during report phase)
|
||||
|
||||
Command line arguments:
|
||||
|
||||
rooturl -- URL to start checking
|
||||
(default %(DEFROOT)s)
|
||||
|
||||
XXX The command line options should all be GUI accessible.
|
||||
|
||||
XXX The roots should be a list and there should be a GUI way to add a
|
||||
root.
|
||||
|
||||
XXX The alphabetizing of the lists makes the display very jumpy.
|
||||
|
||||
XXX The multipanel user interface is bogus.
