Converting Texinfo files into HTML
==================================
Advantages of HTML over Info
----------------------------
Info files are ASCII only; HTML can display text in different fonts
and sizes (if the output device is capable of doing so).
HTML can be browsed remotely and referenced by hyperlinks from other
places in the World-Wide Web.
Problems with using HTML for Texinfo files
------------------------------------------
Texinfo uses various highlighting commands, e.g. @emph{text in
italics}, @strong{text in bold} or @code{text in fixed-width font} and
even @sc{text in small caps}. It translates these to font changes in
the printed manual, and to various forms of quotation marks and/or
upper case in the Info files. Since the generated HTML will be
browsed both in ASCII mode and in multi-font mode, it is desirable
that tags are put in the HTML files which correspond roughly with the
tags used in Texinfo. This means that the WWW browsers must be
changed to recognize these new tags and interpret them accordingly.
Texinfo examples can still contain @-commands, e.g. to put comments in
a non-fixed width font.
Texinfo has names for a (small) number of non-ASCII characters, e.g.
@bullet{} and @equiv{}, which are again displayed different in ASCII
mode than in the printed manual.
Texinfo has some list styles which do not closely map to HTML list
styles.
Texinfo has some styles for which there is no HTML equivalent, e.g.
"@quotation ... @end quotation" adds left and right indents to the
contained text.
Texinfo allows the author more precise control over spacing between
paragraphs and whether the first line of a paragraph should be
indented.
Goals
-----
The primary goal is to be able to convert Texinfo files to HTML for
browsing with WWW browsers; updates will be made to the Texinfo source
files.
Eventually, it may be desirable to edit the resulting HTML instead
(since it is more likely that WYSIWYG editors will exist for HTML than
for Texinfo). This would require that (almost) all Texinfo commands
(and some lay-out features of the source as well!) are translated into
distinch HTML tags, lest information be lost. Ideally, it should be
possible to write a program that translates HTML back into Texinfo
without loss of information.
Suggested changes to HTML
-------------------------
Add '&name.' entities for the special characters used in Texinfo.
Support tags like <CODE>some text</CODE> which is expanded to `some
text' in ASCII mode but uses a fixed-width font in multi-font mode,
and <VAR>name</VAR> which uses italics or upper case.
Create a new form of example tag which produces a fixed-width font and
breaks lines as in the source but does not suppress recognition of
other tags.
