"""GUI interface to webchecker.
|
|
|
|
This works as a Grail applet too! E.g.
|
|
|
|
<APPLET CODE=wcgui.py NAME=CheckerWindow></APPLET>
|
|
|
|
Checkpoints are not (yet??? ever???) supported.
|
|
|
|
User interface:
|
|
|
|
Enter a root to check in the text entry box. To enter more than one root,
|
|
enter them one at a time and press <Return> for each one.
|
|
|
|
Command buttons Start, Stop and "Check one" govern the checking process in
|
|
the obvious way. Start and "Check one" also enter the root from the text
|
|
entry box if one is present. There's also a check box (enabled by default)
|
|
to decide whether actually to follow external links (since this can slow
|
|
the checking down considerably). Finally there's a Quit button.
|
|
|
|
A series of checkbuttons determines whether the corresponding output panel
|
|
is shown. List panels are also automatically shown or hidden when their
|
|
status changes between empty to non-empty. There are six panels:
|
|
|
|
Log -- raw output from the checker (-v, -q affect this)
|
|
To check -- links discovered but not yet checked
|
|
Checked -- links that have been checked
|
|
Bad links -- links that failed upon checking
|
|
Errors -- pages containing at least one bad link
|
|
Details -- details about one URL; double click on a URL in any of
|
|
the above list panels (not in Log) will show details
|
|
for that URL
|
|
|
|
Use your window manager's Close command to quit.
|
|
|
|
Command line options:
|
|
|
|
-m bytes -- skip HTML pages larger than this size (default %(MAXPAGE)d)
|
|
-q -- quiet operation (also suppresses external links report)
|
|
-v -- verbose operation; repeating -v will increase verbosity
|
|
|
|
Command line arguments:
|
|
|
|
rooturl -- URL to start checking
|
|
(default %(DEFROOT)s)
|
|
|
|
XXX The command line options (-m, -q, -v) should be GUI accessible.
|
|
|
|
XXX The roots should be visible as a list (?).
|
|
|
|
XXX The multipanel user interface is clumsy.
