Hi,
recently I got 2 feature requests concerning new tags. Or actually just a
different syntax for existing functionality. Both are directed to better
interoperability with existing html or xml-tools.
The first was to add long syntax for existing short tags. We have already
synonyms <{...}> and <%cpp>...</%cpp>. The former beeing shorter and the
latter more xml-like. The suggestion is to add xml-like synonyms for <$...$>,
<$$...$> and <? ... ? ... ?>. I suggest adding the synonym <%sout>...</%sout>
for <$...$> and <%out>..</%out> for <$$...$>. The third <?...?...?> is not so
useful. At least I and no one else I know do use it any more. I would just
leave it as it is.
Just for your help: <$...$> prints a c++ expression into the page replacing
special html-characters with their html-entity counterparts. In a c++-block
you may use "reply.sout() << something" for that.
<$$...$> do not replace html-characters. It is the same as using "reply.out()
<< something" in c++.
So it would be quite natural to use <%sout> for <$...$> and <%out> for <$$...
$>.
The other suggestion is to add html-comment markers to the tags. So e.g.
<%cpp>...</%cpp> may be written as <!--%cpp>...</%cpp-->. Ecpp-files may be
then edited using ordinary html editors, which will see the c++-things as
html-comments. This is a little more difficult to implement but if it is a good
feature, I would implement it.
My co-worker, who suggested it, uses already this html-comment style using a
sed script to translate the pages before running ecppc, so it is already
somewhat tested in practice.
All ecpp syntax used today will be kept, so that there is no need to change
anything in existing apps.
Any opinions?
