<p>Hi Regex friend :-)</p>
<p><br>
</p>
<p>I assume you are referring to Regex-Core (thanks for the clarification, Levente!).</p>
<p><br>
</p>
<p>Yes, regexes are indeed very nerdy fun, though I recommend to use them rarely in production stuff, they just don't provide a really good readability. I don't know how experienced you are with regex in general, but I can recommend you regex101.com if you
did not know it yet. I'm not sure what you are looking for in detail, but if you're interested in further examples, here are a few ones:</p>

<p><span></span>In <span>Regex-Core-ct.55 f., I extended the implementation of lookaround expressions in Smalltalk.</span></p>

And in as near as possible future, I will commit support for \x and \p as described

<div>You posted an #asRegex example in talking to Eliot about inlining recently. I’ve printed it out and plan to play with it next week.
<div class="">If you have any more thoughts or examples using the VB-Regex package, I hope you’ll post some here. I’m very interested in this stuff. </div>

<div style="margin-top: 0px; margin-bottom: 0px;" class="">as you may have noticed, I have proposed some new features for Regex-Core in recent past, and I found a lot of fun in working with this clean architecture for which I still see a lot of potential for
expansion (for example, I'm currently having basic support for<span class="Apple-converted-space"> </span><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;" class="">U</span><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;" class="">nicode</span> matches
in my pipeline, this is currently blocked by<span class="Apple-converted-space"> </span><a href="http://forum.world.st/Unicode-td5113495.html" class="OWAAutoLink">this thread</a>. For the future, I also would like to consider named groups & depending features).
But before I will invest unnecessary time into the Regex-Core package, I have one question:</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">Recently I stumbled upon VB-Regex, which looks very similar to Regex-Core. Has this been a predecessor of Regex-Core, is it a successor or are they two independent forks? I could not find any information
about this topic on the web.</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">Is my assumption correct that Regex-Core is the regex "state of the art" within Squeak?</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class="">
</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">Best,</div>
<div style="margin-top: 0px; margin-bottom: 0px;" class="">Christoph</div>
