#! /usr/bin/env python """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 -t root -- specify root dir which should be treated as internal (can repeat) -a -- don't check name anchors 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.
