*August is an HTML editor, coded by [Johan Bengtsson](mailto:johanb@lls.se). As August is under GPL, we (Magaz team that is) decided to modify it in order to
|
||
|
|
use it as an SGML editor.*

### [1. Why?]{#s1}
|
||
|
|
|
||
|
|
As everybody (!!!) knows, Magaz is written entirely in SGML, and then converted to HTML with sgml-tools and [Panagiotis Vryonis\'](mailto:vrypan@hellug.gr)
|
||
|
|
especially-modified-for-magaz mapping. Although that decision was made to make the creation of Magaz easier, it looks like most of Greek Linux users wishing to
|
||
|
|
submit - contribute an article had a problem coping with SGML. So, we decided to provide an easy way, for SGML authoring. Instead of writing an article,
|
||
|
|
explaining the SGML concepts, we found out that everybody finally learns what SGML is, and the problem is only the editor. So, Johans\' perfect HTML editor,
|
||
|
|
named [August](http://www.lls.se/~johanb/august/), was used as a base for \"our\" SGML editor.
|
||
|
|
|
||
|
|
|
||
|
|
### [2. August]{#s2}
|
||
|
|
|
||
|
|
August can be found at <http://www.lls.se/~johanb/august/>. It is a complete, non-wisiwyg HTML editor, coded in Tcl/Tk version 8.0. It provides buttons for the
|
||
|
|
most common HTML tags, such as bold, italics, preformatted, listing, underline, alignment, font color and size etc. Most advanced tags, such as tables,
|
||
|
|
column/row span, basic structure, form/script elements, are also supported. Of course, link/anchor creation is easy, through (you guessed it) a button-click,
|
||
|
|
while image inserting and, finally, previewing through netscape, is as easy as pushing the right button.\
|
||
|
|
Other features include the standard open, close, save, copy, cut, paste buttons, commenting, special character inserting, template creation, more than one open
|
||
|
|
windows, options\' settings, uppercase/lowercase letter transformation.\
|
||
|
|
Some of the features apply to selected text (for example bold text), so pushing that button with no text selected will have no effect at all, while some others,
|
||
|
|
such as new paragraph, have no restrictions of that type. That was expected, as not all the tags are the same. Although, the fact that August works that way,
|
||
|
|
really reveals that Johan knows HTML tags (and Tcl/Tk programming) very well.
|
||
|
|
|
||
|
|
|
||
|
|
### [3. SGML]{#s3}
|
||
|
|
|
||
|
|
Sgml is a Markup Language. That means nothing to the most of you, but I\'ll try to explain that. Markup languages, add special tags to text, so that when that
|
||
|
|
text is parsed through a specific program, the tags get a meaning, relative to the appearance of the text. The most well-known and broadly-used markup language
|
||
|
|
is HTML (which, by the way means Hyper Text Markup Language). Others, not so broadly known, are Math ML and XML. All of these (with the exeption of XML) are
|
||
|
|
actually subsets of SGML. SGML, through a DTD (Definition) file, may be converted (with use of sgml-tools, aka linuxdoc) to html, txt, ps, dvi, tex, info, rtf
|
||
|
|
etc.
|
||
|
|
|
||
|
|
If some sgml-tags have no similar tag for the resulting form, they are ignored. So, that\'s the way SGML works. No, it\'s not difficult. It\'s just different
|
||
|
|
(if you already know HTML).
|
||
|
|
|
||
|
|
|
||
|
|
### [4. Modifications]{#s4}
|
||
|
|
|
||
|
|
The modifications, where made against August version 0.30. We hope, if we can find more SGML tags, to make an option, so that August may be used either as SGML
|
||
|
|
or HTML editor.\
|
||
|
|
In order to modify the August, somebody would have to know SGML and Tcl/Tk as good as Johan knows HTML and Tcl/Tk respectively. Unfortunately, I\'m not the one
|
||
|
|
:-( I only know some of the tags we use in Magaz, and, as I have found no documentation at all regarding SGML, I have to admit that my knowledge won\'t get any
|
||
|
|
broader. Although, if anybody knows of a SGML tag not used in modified August, and the equivalent to HTML just let [us](mailto:magaz@hellug.gr) know.

### [5. Feedback]{#s5}
|
||
|
|
|
||
|
|
While August as a program is quite stable, modified August for SGML lacks a lot of functionality. All those form elements, tags, and other stuff missing, could
|
||
|
|
be there, if we get your feedback. You may get modified august from [Magaz\'s server](../files/sgml-edit.gz), try it and then send us your feedback. Together we
|
||
|
|
can make it better.
