The DefaultTiddlers is processed as a filter line [1]: for instance,
instead of just some [[tiddler 1]] [[tiddler 2]] you can put there smth
like this:
[[tiddler 1]]
[tag[tag 1]]
[limit[10]]
So, alternatively to what Eric have suggested, you can create ifOffline
filter (which adds a tiddler only if you opened your TW offline) and use
only one DefaultTiddlers:
[[tiddler 1 to open anyway]]
...
[ifOffline[tiddler 1 to open if offline]]
...
So, the question is -- how to create such a filter? First, let's create a
duplicate of the "tiddler" filter which works in the [ifOffline[tiddler]]
syntax:
config.filters.ifOffline = function(results,match) {
results.pushUnique(match[3]);
return results;
};
(create a tiddler with such code and systemConfig tag -- and the plugin is
ready, but test it first -- put [ifOffline[some existing tiddler]] into the
DefaultTiddlers)
Now, this one adds the tiddler anyway, but we need smth like this:
config.filters.ifOffline = function(results,match) {
if(we_are_offline)
results.pushUnique(match[3]);
return results;
};
the only thing is how to calc this pseudo-coded we_are_offline thing. As
far as I can see from the core code, that should be !readOnly:
config.filters.ifOffline = function(results,match) {
if(!readOnly)
results.pushUnique(match[3]);
return results;
};
Best regards,
Yakov.
