Andrew,
You are right it should be possible to search for and open to a line in a tiddler. I achieve this in a two phase step - Using goto (with SearchOptionsPugin installed) and use the search facility if a tiddler by that title does not come up then on opening a tiddler containing the string use the browsers find in page search. This however is rare because the specific tiddler comes up because that is my unit of data.
You say
What I want to be able to do is preserve the context of the meeting/interaction that the task was
identified as an action item.
I would create a tiddler called "meeting date etc.."
Then use something like the newhere plugin to create (Action) tiddlers tagged with the title "meeting date etc.." and "Action"
Then all meeting related items can be found using the "meeting date etc..", all actions can be found via the Actions tag. I would than tag the action tiddler closed when finished. Another tiddler lists all tiddlers tagged "Action" but not tagged "closed".
I customised new here by the addition of items such as;
newsubTaskHere: {
handler: function(place,macroName,params,wikifier,paramString,tiddler) {
wikify("<<newTiddler "+paramString+" tag:[["+tiddler.title+"]] tag:.subTask>>",place,null,tiddler);
}
},
newProjectTaskHere: {
handler: function(place,macroName,params,wikifier,paramString,tiddler) {
wikify("<<newTiddler "+paramString+" tag:[["+tiddler.title+"]] tag:.projectTask>>",place,null,tiddler);
}
Another method may be to use the ! or !! symbols for headers which can also be seen as sections within a tiddler. You could consider sections to be actions and use the section links plugin and the
<<sectionTOC>> macroTo have all sections (Thus Actions) listed at the top of the tiddler. Once all actions from a meeting tiddler are completed tag it as completed.
The options within tiddlywiki are virtually infinite. The point I am making is the value of content in tiddler size bites linked by tags is very powerful where as resorting to content loaded tiddlers is more limited.
Another tool on the right OS may be to use the FireFox Plugin "It's All Text!" which gives you a simple way to edit textareas, the large text boxes in forms (Read tiddler), using your favorite editor. This editor can have all the grep features you want within your big tiddlers.
Enjoy
