Re: [tlaplus] TLA+ / PlusCalc Cookbook ?



I've been working on it for learntla, but it's gonna be a while before most of the patterns I know are up. Here's what I have so far: https://learntla.com/topics/index.html

Hi Kareem,

There's a few idiomatic TLA+ tips in the Apalache documentation[1] and in the Learn TLA website[2].

The Examples repository[2] on Github contains many advanced examples, including those used in industry.

If I understand you correctly, you're looking for something closer to design patterns in TLA+ -- in the sense that it's generic enough to be applicable in many situations? I'm not sure this kind of resource is available.

Best, 

Jones

I have not seen anything like that however here is a list of repos with TLA proofs used in production systems:

Specifying Systems seems like a great guide for how to think in TLA+, but not a catalog of best practices. What I'm really looking for is a set of patterns based on experiences. Yes, I can probably go through all of Specifying Systems and then write my own way of doing semi-synchronous specs, but why not catalog "here's the best way we've found to do this"?

Thanks,

Kareem

Hey everyone!

I'm a PhD student studying distributed systems at National University of Singapore and I'm just getting started with TLA+. I was wondering if there was a "cookbook" or any kind of reference for best practices? I've seen plenty of example specs for different systems, but, for example, nothing that explains the right way to set up synchronous message queues or semi-synchronous systems. Other examples: byzantine fault tolerance, digital signatures.

Thanks!

Kareem
