Sorry, but there were parse errors in the watch flakes script.
The script I found was:

#!watchflakes
default <- pkg == "cmd/go" && test == "TestScript" &&
           output !~ `The process cannot access the file because it is being used by another process.`  # tracked in go.dev/issue/71112

And the problems were:

script:3.19: unexpected !

See https://go.dev/wiki/Watchflakes for details.

Hi @dmitshur, it seems watchflakes does not like your script, but it's not immediately obvious to me what's wrong with it according to the docs.

Looking at this briefly, I wonder if the watchflakes script lexer has a bug in how it handles !~.

You might be able to work around it by avoiding !~, such as:

#!watchflakes
default <- pkg == "cmd/go" && test == "TestScript" &&
           !(output ~ `The process cannot access the file because it is being used by another process.`)  # tracked in go.dev/issue/71112

Unless it turns out this is explained by something like a simple typo, I will probably open a bug for watchflakes tomorrow, and maybe send a CL. (I have a local change that seemed to work, but want to look at it again, add some tests, etc. This is the first time I've looked much at watchflakes, so this might just be explained by me being confused).

@thepudds Thanks for looking at this too, and suggesting that workaround. I'll use it for now.

I should've posted a comment here sooner, but I think I followed a similar path and ended up with CL 640275. I'm almost done adding some tests, which I'll send to you too, if you don't mind. Thanks again.
