Hi Xavier!
I've already used subfilter. As I used it and understood it, it is of use
as a substitude for mapping within filters. But yes, I can map an array of
just one element. I did not think of that.
As for dictionnary, I was already planning its use. But to mark "é" as a
co-letter for "e", nothing more. But from there, my problem is to build
dynamically the filter for each letter and especially for "e".
Subfilter allow writing something like
subfilter<first-select-filter> prefix[e]
but not something like
subfilter<first-select-filter> <second-filter>
And since there is no filter that could have conditional filter (we can
only have conditional strings with "then" and "else"), I cannot see where
subfilter may help me.
So I looked for another way: using "regexp" instead of "prefix". Where I
would use "regexp<re>" where re is "^[eé]" or "^[a]" for instance. But it
doesn''t work, as I get all the titles, and not only the one beginning with
"e" or "é". See my code for use within "E" tiddler below:
\define glossy()
<$set name="initial" filter="[{!!title}lowercase[]]">
<$set name="others" value="é">
<$set name="pattern" value="^[<<initial>><<others>>]">
filter <<filter>>
<ul>
<$list filter="[tag[glossaire]regexp<pattern>]
+[sortan[]]"><li><$link/></li></$list>
</ul>
</$set></$set></$set>
\end
<<glossy>>
with the control of "others", I'll be able to achieve my goal. But I have
difficulty with regexp (but not with regular expressions per se) which I
shall address in another topic.
