Function Hijacking of TiddlyWiki.prototype.reverseLookup

[Clint Checketts]

I want to extend the TiddlyWiki.prototype.reverseLookup method,
however, the typical technique doesn't seem to work. Any tips?

[Jeremy Ruston]

Because it's a prototype method, I think you'll need to do something like:

store.reverseLookup = function(lookupField,lookupValue,lookupMatch,sortField)
{
// ...
// Call the old implementation
TiddlyWiki.prototype.reverseLookup(lookupField,lookupValue,lookupMatch,sortField)
// ...
}

I haven't tested this, though.

Cheers

Jeremy

As a followup, Jeremy's technique does work, however the prototype functions all reference the 'this' keyword so I need a way to grab the 'this' again.

I do this kind of thing a lot in ZiddlyWiki...

TiddlyWiki.prototype._reverseLookup =
TiddlyWiki.prototype.reverseLookup;
TiddlyWiki.prototype.reverseLookup =

function(lookupField,lookupValue,lookupMatch,sortField) {
// ...
// Call the old implementation

results =
this._reverseLookup(lookupField,lookupValue,lookupMatch,sortField)
// ... do something with results (or not)
}

If that doesn't work, you might try using the JavaScript call() method:

store.reverseLookup =
function(lookupField,lookupValue,lookupMatch,sortField) {
// ...
// Call the old implementation

TiddlyWiki.prototype.reverseLookup.call(this,lookupField,lookupValue,lookupMatch,sortField)
// ...
}

A while back I modified TW to not do live searching to make it more responsive with a TW I have with ~1500 Tiddlers. That tiddler is a great reference that I use all the time and would like to be able to search it from other pages or Tiddlywikis.

Is there a way to have TiddlyWiki receive a posting from a html form on another page/across the web. When I try to permaview a search, I get the results as the URL, not the 'query' that produced them. It looks like all the search goodness is embedded in the javascript search function. How would I send something to it across the web...?

Dear Jonathan,

 

I think that the answer is not yet. The url is currently parsed assuming that the user is supplying a list of tiddlers. In my code I will be wanting to make some modifications to supply other parameters though I havent considered what the syntax might be as yet, so I think that some discussion could be in order.

I think the usual syntax for a url is something like this

 

url#anchor?param=value&param2=value1

 

currently the 'anchor' field is used to pass in the list of tiddlers to be viewed, and there is no code to handle input/form parameters.

 

I want to have the user be able to select a named wiki, one of several contained in a single TW file, and supply a list of tiddlers to display, but I would like the named wiki to be earlier in the url rather than later... to do this I think that the result would end up looking something like this.

http://blah.com/tiddlypom.html?wiki=admin&t=MainMenu%20StyleSheet  etc etc

[Daniel Baird]

So, to solve the original problem, what we need is a macro or something, that you can put into a tiddler that does a live search when the tiddler is opened.  Then Jonathan could create a tiddler called "HowCoolArePirates" (for example), with contents something like:

!How much do pirates rock?

Here's everything I know about pirates:

<<liveSearch pirate>>

and the liveSearch macro would run a search on the word "pirate" or whatever and either show the search results inside the tiddler, as tiddler titles, or even open all the matching tiddlers up like a normal search does.

Then Jonathan just has to permalink to the HowCoolArePirates tiddler, and everyone's happy.

So there you are chaps -- a feature request.. at the speed TiddlyWiki development goes, I expect this to be on my desk by the morning :)

in my old adaptation, based upon version 1.2.6 (stone age), I modified
the parser to accept other meanings of the url:, e.g. it could be a
search string or a tiddlergroup or all tiddlers created at a given
date.

Something a bit like this, perhaps? (watch those line breaks when you
cut'n'paste...)

// //''Name:'' liveSearch macro
// //''Version:'' <<getversion liveSearch>> (<<getversiondate
liveSearch "DD MMM YYYY">>)
// //''Author:'' SteveRumsby

// //''Syntax:''
// //<< {{{liveSearch //string//}}} >> or << {{{liveSearch //string//
//prefix//}}} >>

// //''Description:''
// //The first produces a simple list of tiddlers, one per line, that
match //string//. The usual search rules apply, including the regexp
search option.
// //The second produces the same list, but with //prefix// before
each tiddler and with the result being wikified, so that a prefix of
//*// will
// //produce a bullet list, etc.

config.macros.liveSearch = {};

version.extensions.liveSearch = { major: 0, minor: 1, revision: 0,
date: new Date(2005, 08, 09)};

config.macros.liveSearch.handler = function(place,macroName,params)
{
var matches = store.search(params[0],
config.options.chkCaseSensitiveSearch,config.options.chkRegExpSearch,"title","excludeSearch");
var string = "";
for(var r=0;r<matches.length;r++) {
if(params[1]) string = string + params[1] + " ";
string = string + "[[" + matches[r].title + "]]\n";
}
wikify(string, place, null, null);
}

This produces a simple list of tiddlers, a la listTags. It would be
easy enough to produce a version that opened them all instead, or even
a macro that gave you the choice...

Happpy to oblige...:-)

I'm still figuring out how this would work. What I'd like to do is search a different TiddlyWiki that the one I'm currently in. (Admittedly that macro seems useful, too. I'll have to think about how I'd use it.)

When I was reading Google Hacks, I learned that you can create a pretty simple form to send a complex query to Google. I used it to search for pdf files. Essentially what I'm thinking is inserting a second search box that would open up a different Tiddlywiki and run that search. Perhaps I can do this with GreaseMonkey/Javascript?

Man, I'm still freaked out about how easily great useful bits are being added to TiddlyWiki!

Freaked out! Me too, its driving me nuts trying to keep up while trying to code some cool features that will not pluginize

 

patience is needed I think

Sorry for being offtopic and silly, but [I just noticed] [1] that
google comes up with weird ads in this topic.

anti-offtopic: the hyperlinking style I used here is from [markdown]
[2]. I find some bits of markdown (backticks for code, reference style
hyperlinking like above and ![images like this] [3]) very nice and
consider adding a plugin for them (maybe based on [js-markdown] [4] if
the site comes back up)

that is pretty funny!

[Daniel Baird]

I misunderstood your request Jonathan -- i thought you wanted to link to the live results of a specific, pre-determined search, from outside (which Mr Rumsby kindly provided a few hours later -- cheers Steve).

What you actually want (if i understand correctly) is, given two tiddlywikis TW1 and TW2:
- in TW1, have a place to type text, and a search button
- when you click Search, open TW2 and run a search in TW2 for the text you typed into the text box in TW1

That seems a bit harder, and I think Christian's right, the sensible way to do it would be to use some kind of addition to the url (as you point out in your original post :).

If you just want it for yourself, it's probably not too hard to kludge something up in greasemonkey.  Otherwise I guess there will need to be something that gets notified on open, like refreshTitle() etc.  I'm sure when Jeremy finally writes his developer's book on TiddlyWiki there'll be a chapter on doing stuff when the page opens..

Anyway I already know I won't have time to do any coding so this is all just blather.  I'lll cross my fingers that someone else gets inspired..

really weird, looks like it was my entry (#12) above. Might b ebecause
of the words "External control", that it triggers "animal repellent"?
And even stranger: years ago, in my job (drug metabolism studies), I
was indeed analysing the contents of animal and human urine!

[Jonathan Ploudre]

I was reading today and found out about the location.search part of javascript. Apparently you can create a simple form that will add your search term to the URL (in TiddlyWiki 1) and then get that search term back in Tiddlywiki 2 using location.search.

Since I'm not a real programmer, it may take a little time to figure out how to get the search part of tiddlywiki to use that as the search term.

http://www.eggheadcafe.com/articles/20020107.asp

has some examples of ways to can get data into another page.
