Support use with multiple compilers

[PaulRBerg]

When running solidity-docgen in a project that uses multiple Solidity compilers, I am getting this error:

Error: Solidity was unable to compile. ParserError: Source file requires different compiler version (current compiler is
    0.8.9+commit.e5eed63a.Emscripten.clang) - note that nightly builds are considered to be strictly less than the released version
     --> contracts/uniswap-v2/UniswapV2Pair.sol:3:1:
      |
    3 | pragma solidity =0.5.16;
      | ^^^^^^^^^^^^^^^^^^^^^^^^

How could I use this tool with multiple Solidity compilers?

Side note: it might be worth it to enable discussions in this GitHub repository.

Thanks for the suggestion, I've enabled discussions.

Currently you would only be able to run in this context by keeping those contracts in separate directories, and including the option when running -i contracts/subdir.

Nice. You can also convert this issue to a discussion - there's a button on the right-hand side of the screen.

Argh, yeah I'll have to refactor my code. Thanks anyway!

Sorry about that!

Keeping this open as an issue because I recognize it's a legitimate problem we should solve, and it's going to happen more and more as projects mature.

Eventually the solution is I think to turn this into a Hardhat plugin where compilation is done by Hardhat which already supports multiple versions. We lose some generality by tying to Hardhat but we could add a fallback to something like what the tool does today.

We've got the same problem. Hardhat plugin will do great for us.

Hardhat plugin is being worked on, see #350.
