0% coverage when using hardhat-foundry & foundry.toml is present

[jd1900]

After checking the new FAQ options on https://github.com/sc-forks/solidity-coverage/blob/master/docs/faq.md#running-out-of-stack I'm still having the same issue.
With Work-arounds #1 and #2 it compiles, but only the interfaces are covered. The rest at 0%.
With Work-around #3 I'm getting this error:

Compilation:

@jd1900 Am actively working on a patch that will let you use viaIR without any special config. If it works (fingers crossed) will ping this issue shortly (within next 2 days) to ask you to trial a beta of it.

Thank you @cgewecke !

@jd1900 The patch is published at the viaIR tag.

npm install --save-dev solidity-coverage@viaIR

You should remove all the .solcover.js compiler config stuff from the workarounds and just have viaIR: true in your hardhat.config.ts compiler settings. LMK if it works, or doesn't, thanks for trying it out.

I've just tried it. It doesn't crash or complains about the stack too deep.
Unfortunately I got the same result, interfaces 100 and non interface contracts 0.

[cgewecke]

@jd1900 I ran it against 1inch's solidity-utilities locally and it worked.

Could you try running npx hardhat clean to double-check that's not the problem?

Also ... to make sure you've installed the correct version, you can check the version info at the top of your coverage run:

Am happy to debug this if you can provide a public repo link or invite me to private repo.

Unfortunately, same thing:

@jd1900 I've just opened a PR showing how I installed and ran on a fork of 1inch/solidity-utils here:

cgewecke/solidity-utils#1

It's passing and its coverage is identical to their master branch using 0.8.6. Could you compare what you are doing locally to this repo and find the relevant difference?

That's what I did, the instructions you gave. But it just doesn't work, as shown above.

[cgewecke]

@jd1900 Why is it working in solidity-utils and not in your project?

Could you compare what you are doing locally to this repo and find the relevant difference?

[cgewecke]

Closing via #854 because just published 0.8.7. If you can provide me with a reproduction case very happy to look into it though.
