Josiah,
I am busy at the moment but I am sure I can brainstorm some cases for
regex.
Does defining a macro containing the regex then using regexp<macro> resolve
the use of "[ ]"?
Off the top of my head
- The equal test (already)
- The Not equal test if there is one
- Searching for common tiddlywiki patterns `{{ }} {{!! << [[ ||` and
when they have matching braces extract what is between them
- Imagine if we could search for the use of templates
`{{something||template}}`
- Given a keyword find "keyword:" "[[keyword]]" etc...
- Find keyword pairs eg keyword="value" keyword:"value" keyword:value
need to account for ' "" """
- Search values and get values (less the keyword)
- Find the delimiters in use eg [[]] "," "/"
- Count the number of delimiters eg how many "/" in a title
Any thing which results in a numeric output will have more value than ever
with the introduction of maths operators.
Regards
Tony
