1 points · Open discussionThere is a PlusCal -> Go compiler[1] and, as I mentioned in a comment on a thread linked in another response to your question, there are tools to translate C and Java code to TLA+ for verification. But as a relatively experienced TLA+ user, I see almost no value in doing the first, and little practical value in the second.
The kind of properties you want to reason about in TLA+ are so global and fundamental, that the code you'd end up writing would both be too far removed from the high-level spec, and the process of translation would be negligible in the grand scheme of things, so that an automatic translation, if it is able to produce usable code at all, wouldn't really save you any time.
That's not to say that you shouldn't also reasons about more local properties at the code level, and there are good code-level verification tools (adva

nced ones include Frama-C for C, OpenJML/Krakatoa for Java and SPARK for Ada) just for that.
It is possible to use TLA+ (and other tools, like Coq or Isabelle) for what's known as end-to-end verification, which means verifying the important global properties all the way down to the code level (and even machine-code level), but the process is so laborious that it is virtually never worth the effort, and, in fact, it has never been achieved for any but very small programs (and even then at great cost).
