How to make your WWW client grok the setext

If the sv has compiled cleanly and appears to be working (test by launching it with the as an argument), you should be able to have your WWW client recognize it and handle transparently while browsing the web. The following instructions are for the Lynx-2.3 (VT100) browser, but should in principle work with other Unix clients. Technically the sv acts just like a text filter.

  1. Have the client react properly to the default .etx (and .ETX) suffix used to distinguish setext-formatted matter from mere plaintext (the suffix stands for Enhanced TeXt).

  2. In Lynx-2.3 Beta, the current distribution version, this is already done in source code, so documents with such suffixes automatically are treated as MIME type text/x-setext. By default the Lynx does not know about the sv, however... after all there could be more than one setext client in existence. So we have to alias the two somehow. Add those two lines to your ($HOME/) lynx.cfg (or equivalent) configuration file:

    VIEWER:text/x-setext:sv %s
    PRINTER:setext viewer:sv %s %s:TRUE

  3. Older Lynxes and possibly other clients may require to have the binding suffix--MIME-type defined explicitly. In $HOME/.lynx.cfg this would look like this:


  4. Now, quit, do 'rehash' and launch the client by pointing it at any setext file ('' in the package will do nicely). The browser should launch the sv automatically, and have it display the setext doc in a structured manner. Upon quitting/ leaving the sv you should be returned back to the WWW-client.

  5. Observe that once a browser has been configured to recognize setext and process it automatically the only way to extract/save such documents locally will be by using the -source or equivalent fetch-raw-document option of your browser. In the Lynx this would be:

    % lynx -source scheme://site/path/file.etx

That's it, folks. Ready for a browser?
