awesome-workflow-engines VS RE2

I've come across this list, but I'm uncertain about which option would suit my requirements without going through a trial-and-error process. Do you have any recommendations for a tool similar to "Postman flows" that enables the creation of chained HTTP requests and allows for response analysis?

True, there are many options out there. And we looked at a good number before we made the decision to build one ourselves. But at least at the time (circa 2014), many of the existing options were either not designed for a distributed environment, were designed more particularly for data-processing use cases, were seemingly abandoned, or simply felt over-engineered to our taste.

I'd say give Temporal (https://temporal.io) a look, but there are a lot of options (https://github.com/meirwah/awesome-workflow-engines).

I believe the type of software you're looking for is a workflow engine. I've found this list of them, perhaps there's some in the list that could work for your needs: https://github.com/meirwah/awesome-workflow-engines

https://github.com/meirwah/awesome-workflow-engines links to a bunch of open source workflow engines. If you don’t find a tutorial, maybe try one of those and see if the code is small enough to read easily.

Looking at the benchmark where C++ is worst compared to other languages, it's depending on the library used. I would guess if they used Google's re2 Regex library instead of Boost's, the result would be different.

That page says it just includes "some of the most common special characters", and following the link to the Examples page in turn includes a link to the full list.

Python uses backtracking, so this probably isn't O(n), especially with the ability to choose the dictionary.

But with there are non-backtracking matchers which would make this O(n). Here's re2 from https://github.com/google/re2 :

  >>> import re2

RE2 is a Google regular expression library

I am currently working with Regex, specifically Re2, and was wondering if there is a real difference between the above expressions for repeated sub-regex.

I ported Google RE2, a regular expression library, to SPVM as Resource::Re2, and created SPVM::Regex, a wrapper for it.

I searched for I found that there is a Perl compatible regular expression called Google RE2. It is written in C++, and with Google RE2, I can use Perl-compatible regular expressions as a library.

Yes, but there is an interesting clarification here. RE2 has used the "caching" approach documented in the Ruby bug ticket linked for quite some time (since its birth?): https://github.com/google/re2/blob/954656f47fe8fb505d4818da1...

It is mentioned only briefly in Cox's article on regex matching in the wild. Look for the word "bitstate": https://swtch.com/~rsc/regexp/regexp3.html

I didn't know Perl had implemented this trick too.

The paper[1] cited in the Ruby bug ticket was published very recently. When I first read the Ruby bug ticket, I immediately wondered how they sidestepped the memory use problem. The paper's abstract seems to suggest there is some technique for doing so, as it rebuffs the idea of doing "full" memoization. Alas, I do not have access the paper. (Which is fucking ridiculous.)
