The SuperScheme Browser.


This program is intended solely for displaying the 287 course material. It makes use of the VED editor to display .html files to the best of VED's limited ability. It works by taking a ".html" source file and creating a temporary ".htmlo" file which is then displayed by VED.

Hyperlinks appear in underlined blue text as in Netscape. Like this:
Back to the index

But the browser doesn't remember that you have visited a particular one.

You can't change the text as displayed by the browser by typing (unless your username is "pop"). You can, however, copy it into your programs in the usual way. Note that you can actually cut text. This is inadvisable, since the hyperlinks will cease to work for that particular buffer.

Information that is intended to be regarded as program text will appear in red.

Limitations

(1) Only a single font, and its variants (coloured, underscore, bold etc.) are available to VED. So headers are indicated by an underlining convention.

(2) Figures can only be displayed by the "xv" program in a separate window. To get rid of a figure, use the right mouse button to pull up the xv control panel, and select "quit".

(3) Tables are not implemented, neither are certain forms of indented lists.

(4) The browser is much more particular about (some of) the rules of HTML than is Netscape. It puts a "BAD HTML..." message in the output if it doesn't like what the author has done.

(5) I haven't implemented comments correctly. A comment must have the form

        <!-- XXXXXXX -->

with a space after the first "--".

If I have time, I'll adapt it for browsing more widely, but (sigh!) don't expect to make inroads into Netscape's profits...

(6) See the above-mentioned ability to change the .htmlo text by cutting or pasting into the text. This WILL upset the hyperlink following mechanism

(7) Information about the hyperlinks etc. is appended to the end of the .htmlo file. Currently this is left in place in the edit buffer, though the intention is to crop it off.

(8) Only one hyperlink per line of text is permitted. And it should not be integrated with other text.
