Regexp question (beat Roam at its own game)

[David Gifford]

How would I do the following?

1) List all the tiddlers, whether system or non-system, that have the title of the current tiddler in their text field.

2) display just the lines, not wikified, from those tiddlers that contain the title of the current tiddler

[David Gifford]

Here is what I came up with for the first part:

''References in other notes:''<br>

<$list filter="[!is[system]regexp:text{!!title}sort[title]] [is[system]regexp:text{!!title}sort[title]] -[is[current]] -[[$:/HistoryList]]"><$link><span class="graybox"><$transclude field="text" mode="block" /></span></$link></$list>

Now I just need to know how to display the context, in the listed tiddlers, of the mention of the current tiddler's title.

I would also be willing to consider the following, if it is simpler:

Transclude the entire listed tiddlers, and highlight the mentions of the tiddler title referenced from them.
