How to disable typechain by default?

[AlissonRS]

When I run hardhat compile task, it automatically generates types via typechain:

Generating typings for: 119 artifacts in dir: src/types for target: ethers-v5
Successfully generated 316 typings!
Compiled 109 Solidity files successfully (evm target: paris).

I don't want this behavior. If I want types generated, I'd like to explicitly run hardhat typechain task for that.

The reason is that I have the types under version control because I distribute them via NPM package. However, we also use solidity-coverage to run coverage on our unit tests, and because it uses different compiler configs than we have in our hardhat.config.ts file, it modifies types with different bytecode, so devs can accidentally push types with the bytecode generated by coverage task.

From what I know, it's not possible to disable type generation when running hardhat coverage as it just runs the compile task internally before running.

Hi @AlissonRS, sorry for not responding sooner!

As far as I know, there's no way in typechain to configure this. But you can disable it yourself by overriding the compile task:

task("compile").setAction(async function (args, hre, runSuper) {
  return runSuper({ ...args, noTypechain: true });
});

Is that workaround enough for you?
