MOTHRA(1)                                               MOTHRA(1)

     NAME
          mothra - retrieve and display World-Wide Web files

     SYNOPSIS
          mothra [ -va ] [ -m mtpt ] [ url ]

     DESCRIPTION
          Mothra uses webfs(4) to retrieve and display files from the
          World-Wide Web, by name or through hypertext links.  Web
          names, called URLs, have a peculiar syntax:

               http://9front.org/
               https://code.9front.org/hg/plan9front/
               http://cat-v.org/

          The part up to the first colon gives the protocol for
          retrieving the file.  http:, Hyper-Text Transfer Protocol,
          is the usual way of accessing web files.

          // begins the Internet address of the server where the file
          resides.  The address may contain a colon and a TCP port
          number, which overrides the default port number for the ser-
          vice.  Next comes a file name.  Finally, the file name may
          be followed by # and a string giving a label within the file
          where the display should begin.

          Mothra starts with the url given on the command line,
          defaulting to the environment variable $url.

          There are a number of options:

          -a   Alt display. Starts in alt display mode, see menu com-
               mands table below.

          -m   Specify the webfs(4) mountpoint with -m mtpt. The
               default is /mnt/web.

          -v   Verbose mode. Causes HTML errors to be printed on
               file-descriptor 2.

          The display contains the last message from mothra, a box
          where typed commands appear, a scrollable list of previously
          visited files, the title and URL of the current file, and
          the scrollable text of the current file.

          Button 1 selects and displays a file, either from the list
          of previously visited pages or from a link (indicated by
          underlined text or a boxed image) in the current file.  But-
          ton 2 shows the URL of a file, but does not retrieve or dis-
          play it.  Button 3 pops up a menu of commands:

     MOTHRA(1)                                               MOTHRA(1)

          alt display  Collapse or expand the navigation boxes at the
                       top of the browser window.
          moth mode    Enter moth mode and switch to the moth cursor.
                       If the HREF of an image link is different from
                       the URL of the image itself, a link to the HREF
                       will be printed on the right side of the image.
                       Clicking an image or link with mouse button 1
                       prompts the user to save a copy of the file in
                       the current directory.  Clicking mouse button 2
                       sets the target as the current URL.  Clicking
                       the moth mode menu option again exits moth
                       mode.
          snarf        Copy the current entry text or selected page
                       text to snarf buffer.  If nothing is selected,
                       the current URL is copied.
          paste        Paste the snarf buffer to the current text
                       entry.
          search       Search for a regular expression in the current
                       page.
          save hit     Save the current URL to the hit list.
          hit list     Retrieve and display the hit list.
          exit         Ask for confirmation and quit.

          The typed commands are:

          a               Toggle alt display.
          g url           Go to the page with the given URL.
          j n             Jump to page n from the list of previously
                          viewed pages.
          k               Kill images on the current page.
          m               Enter or exit moth mode.
          r               Reload the current page.
          s file          Save the current page in the given file.
          W file          Capture a screenshot of the entire browser
                          window in the given file.
          w file          Capture a screenshot of the content area in
                          the given file.
          q               Quit.

          When mothra retrieves a direct link to a file that is not an
          HTML document (for example a GIF or JPEG image), it will
          start up an appropriate viewer, for example page (see
          page(1)) for most image files.

     BUGS
          Files are saved in the form received, not in the form sug-
          gested by the name in an s command. A directory index saved
          from moth mode may be written in the local directory as a
          file named index. Sanitizing remote file names for the local
          file system is imperfect.

          Mothra is distributed in a preliminary state; it has more
          than its share of bugs. Note that mothra, like the other
          Guardian Monsters, has no particular concern for humanity.

     HISTORY
          Mothra first appeared in Plan 9 from Bell Labs (1995). It
          was later modified for inclusion in 9front (September,
          2011).
