With regex enabled, please try searching for:

={1,3}?

where:

{x,y} = match the preceding element x - y times.

1 is the minimum number of characters to match.

3 is the maximum number of consecutive characters to match.

? = nongreedy

Wrap your search with ^ and $ to match only = characters.

There really needs to be something to match after the ? to make the non-greedy search useful.

In Everything I use (.*?)\(.*?) to match anything and break at the first \ (non-greedy)

Didn't realize, wasn't sure if you could do that.

I thought, wasn't sure, if it only applied to .* and .+

But it looks like it is doing, something.

Compare:

greedy, on the last item

Code: Select all

```
regex:(z)\1{1,2}?.*?\1{1,2}
zzy_osbourne_blizz
```

non-greedy, on the last item

Code: Select all

```
regex:(z)\1{1,2}?.*?\1{1,2}?

Incorrect pattern because it matches all characters!

Found:15 matches

Code: Select all

`={1,3}?`

Code: Select all

```
=
==
===
====
=====
```

Note the differences, anchored or not, & greedy or not.

Without the anchor, non-greedy, I suppose it finds solely "=", then if searches for more, the same way, & finds any additional "=" - if they exist.

So in that respect, it appears as if it is finding "all" =, where in fact it is finding a single {1,3}? "=", but multiple times.

Once the anchor is added in, you can "see" that it is only finding the initial =, with the search, even though you have {1,3}, ending at that point - because non-greedy.

Remove non-greedy, but keep the anchor, & "=" or "==" or "===" are matched, greedily, but no more then that.

Invalid pattern because it finds more characters, and a specific number of characters is given:

^(=){3,3}

Correct:**===**

Wrong:**===**=

Wrong:**===**==========

Working:

^(=){3,3}$

^(=){3,3}

Correct:

Wrong:

Wrong:

Working:

^(=){3,3}$

Well, ^(=){3,3} is correct, all your results are correct, it's only that you do not want a result included if it is followed by (one or more) additional =.

And yes, ^(=){3,3}$ will meet your criteria.

I tried something like ^(=){1,3}[^={4,}], kind of to mean = or == or ===, but not followed by any further = characters, but my thoughts/syntax haven't panned out to accomplish that, yet...

so more than = are not allowed

Example:

^={1,3}(?![=]+)

Example:

^={1,3}(?![=]+)
