I’ll try and explain the syntax as we go, but you can use the TLA+syntax cheatsheetto find any symbols you don’t understand. The files for the different steps are linked in the respective sections so you don’t have to do copy-pasting. First, some fundamentals. TLA+ is heavily base...

and other tasks making use of its fully-featured syntax tree query API. This grammar is intended to function gracefully while parsing a source file mid-edit, when the syntax isn't fully correct. It is also fast enough to re-parse the file on every keystroke. You can take the parser for...
In this paper, we provide a reusable TLA~+ module for specifying and model checking asynchronous message-passing systems. TLA~+ syntax and semantics are introduced as we describe the module.Amy HousePeiyi TangIEEE SoutheastCon

then you’re fine. We’re not looking at race conditions so you shouldn’t need to know the finer points of labels and actions, but it might make things more intuitive. I included syntax explanations where appropriate. It also assumes some basic knowledge of Go, which I am in no way qu...
To make the example in the talk more accessible, I invented my own syntax for TLA+. All of changes are 1-1. For example, instead of[key |-> val]I wrote{key: val}. I also only showed a subset of the full spec in the talk. In a real system, there are all sorts of invariants...
TLA We now describe the syntax and semantics of TLA. The description is illustrated with the formulas de?ned in Fig? ure 1. (The symbol = means equals by de?nition.) We assume an in?nite set of variables (such as x and y) and a class of semantic values. Our variables are the ?
