Mothra is a World-wide Web browser. Its display looks like this:
The display's regions, from top to bottom, are:
- Error messages and other information.
- The name of the currently selected url.
This may be different from the displayed url.
- A text input window in which commands can be typed.
- A scrollable list of titles of previously visited documents, with the most recent first.
Pointing at one of these lines with mouse button 1 revisits the document.
- The title of the currently-displayed document.
- The URL of the currently-displayed document.
- The scrollable document display. Underlined text and
images surrounded by boxes may be pointed at with button 1 to
visit the files that they refer to. Files that are not
HTML documents (for example images or mailto: urls) cause
9v or mail to pop up in a new 8½ window.
Pointing with button
2 instead of button 1 selects a url without following it;
the url will be displayed in the selection: area and commands
will refer to the url, but it will not be drawn in the document display.
Button 3 pops up a command menu that contains
- alt display
switches to (or from) the alternate display, which shows only
the scrollable document display area. This might be useful when running mothra
in a small window.
- snarf url
copies the selected url into the snarf buffer.
appends the snarf buffer to the command window.
- inline pix
turn off/on loading of inline images. Image maps cannot be disabled.
- fix cmap
reload the default plan 9 colormap
- save hit
appends the selected url to file:$home/lib/hit.html
- hit list
The commands you can type are:
- g [url]
get the page with the given url (default, the selection.)
- r [url]
refresh the display if the URL changes.
Otherwise, you will probably see a cached version.
- s file
save the current page in the given file.
- w file
write a bitmap image of the document display area in the given file.
Mothra gets configuration information from the environment.
The default url displayed when mothra starts.
A url given on the command line overrides this.
The default is /sys/lib/mothra/start.html
The network address of an http proxy server,
in the format expected by dial(2). If $httpproxy is not set
or is null, no proxy server is used.
If the mothra command has an argument, it is the name of a url to visit
instead of the startup page. Giving mothra the -i flag disables loading
of inline images. The inline pix menu item will reset this option.
Mothra creates several files in $home/lib/mothra.
a list of all the url's visited
a log of error messages, mostly uninteresting
the hit list used by the save hit
and hit list commands. Since save hit only
adds new urls to the end of this file, it is safe to edit it
to add annotation or sort the saved urls.
