Re: [Karrigell-main] Indentation in PIH

[Pierre Q. <que...@wa...>]

Yes, if you use this tag you must follow Python indentation rules ; by =
the
way, I have renamed it <indent> and </indent> instead of <%% and %%>

But the use of <indent> is optional. If you don't use it, the rules =
remain
as follow :
- indentation starts from 0
- it is incremented by one every time a Python chunk (between <% %>) =
ends
with a colon
- it is decremented by one with <% end %> (difference with version 1.1 =
of
Karrigell where it came back to zero)

So for a multiplication table you can choose between two versions :

1 - version without <indent">
--------------------------------
<table border=3D1>
<% for i in ['h']+range(10): %>
<tr>
    <% for j in ['h']+range(10): %>
    <% if i!=3D'h' and j!=3D'h': %>
        <td><%=3D i*j %></td>
        <% end %>
    <% elif i!=3D'h': %>
        <th><%=3D i %></th>
        <% end %>
    <% elif j!=3D'h': %>
        <th><%=3D j %></th>
        <% end %>
    <% else: %>
        <td>*</td>
        <% end %>
    <% end %>
</tr>
<% end %>
</table>
--------------------------------
(in this example, everything could be unindented, or indented in a =
different
way)


2 - version with <indent>
---------------------------------
<table border=3D1>
<indent>
<% for i in ['h']+range(10): %>
    <tr>
    <% for j in ['h']+range(10): %>
        <% if i!=3D'h' and j!=3D'h': %>
            <td><%=3D i*j %></td>
        <% elif i!=3D'h': %>
            <th><%=3D i %></th>
        <% elif j!=3D'h': %>
            <th><%=3D j %></th>
        <% else: %>
            <td>*</td>
    </tr>
</indent>
</table>
---------------------------------

It is perhaps more readable, and avoids the use of many <% end %>. I'm =
aware
that it has its drawbacks, for instance all consecutive HTML line *must*
have the same indentation, you can't write :
<indent>
<tr>
    <td>A cell</td>
</tr>
</indent>


A more complete explanation is on CVS
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/karrigell/Karri=
gell/doc/en/pythoninsidehtml.htm?rev=3D1.4

Also see the last version of the PythonInsideHTML.py module on the CVS, =
it
includes a GUI application which shows how PIH files are parsed

All this remains open to discussion...
