Filter to select UPPERCASE titles

[Alex Hough]

Hello all,

A set of tiddlers is formed by their titles being all upper case.

INDEX

GLOSSARY

I could tag these, but I wondered about selecting them based on regex filter. Using https://regex101.com/ I got this far 

However when I put the term into TW's regex filter I get no return

Here is a minimal test case : https://alexhough.github.io/RegexAllCaps.html

Any pointers most welcome

This one seems to work:

 value="^[^a-z]*$"

[Alex Hough]

Thanks Mark!

i know next to nothing about regex... could you recommend a good place to look?

I've updated my test case

Dear Alex,

Regex101 is a great place to learn and experiment with. Just make sure that you select the appropriate regex flavour. See the image attached

the power of RegEx combined with TW is a box well worth opening IMO.

in some ways much going on in TW is enhanced RegEx veiled in JavaScript :-).

Sorry to say, but your solution is faulty as you will get hits on any title without a lowercase letter. Naming a Tiddler "???" for example will also appear in your list.

You should use:

value="^[A-Z]+$"

if you wish to capture all cap titles that may also end with exclamation points, do this:

value="^[A-Z]+[!]*$"

If you want all caps that may end with or without exclamation points or question marks, do this:

value="^[A-Z]+[!?]*$"

If you want those plus titles that are all question marks or exclamation points [like ??? or !!!! titles] do this:

(^[A-Z]+[!?]*$)|(^[!?]+$)

It is always better to capture what you do want, not to capture everything but with a few exceptions. Otherwise, you open the door open to let in things you hadn't thought of.

I left spaces out of my examples.  So all caps with spaces is:

value="^[A-Z\s]+$"

If you will also accept ? or !, but only at the end, then do this:

value="^[A-Z\s]+[!?]*$"

If you had a tiddler titled "RELEASE 5.0.181-BETA", your current RegEx would have captured that too.

"33333" would also have been captured. Examples like these are why you want to capture specifically what you are looking for.
