Incompatible with solpp?

[ddnexus]

Not sure whether this is an issue that has some work around. The coverage is 0 on all contracts.

We need to use the hardhat-solpp plugin to inject addresses and other stuff at compilation.

The plugin configures solpp preprocessor so it processes the contracts sources in the contracts dir into the cache/solpp-generated-contracts and uses them when testing.

I suspect that running solpp with solidity-coverage HH plugin may remove the instrumentation solidity-coverage injects into the contracts (as reported in #715).

Is that a probable cause?

I guess that a possible workaround (that I don't know how to setup) would be making solitidy-coverage use the previously generated contracts in the cache/solpp-generated-contracts as the actual source (and disabling at the same time solpp).

Is there a way to tell solitidy-coverage to look into the generated dir for sources instead of in the contracts dir?

Thank you.

OK, so I tried my work around and it worked. Not sure whether this is the best solution, but it looks pretty clean to me.

// hardhat.config.ts
{
...
    paths: {
        sources: process.env["COVERAGE"] ? "./cache/solpp-generated-contracts" : "./contracts"
...
    solpp: {
        noPreprocessor: process.env["COVERAGE"] ? true : false
...
}

Then call the task with with COVERAGE=true hardhat coverage

Looks good to me! Thanks for the workaround.
