Re: [tlaplus] Toolbox Plugin development



No worries, I have updated the README with this information - it is useful for people to know the "important" files in a repo and easy to overlook documentation like this when you're familiar with a project.

The language spec in Specifying Systems is for TLA+ version 1. Almost all of it still applies to TLA+ v2, but there are a handful of differences like how imported infix operators are used.

Oh, that is a great relief. My humble apologies for my strong language, and thanks for the pointers to better resources.

It is a relief to think that no-one thinks that this kind of JSON would be a good way to create a grammar.
That doesn't explain XSLT, of course.
/me ducks :)

Chapter 15 is especially useful. I'll see if I can finally establish the common semantic elements TLA+ has with my Constellation Query Language (which has no temporal aspect, but does handle FOL).
