Solcjs can't write output on Windows machines due to path separators

[0x-r4bbit]

Looks like there's a bug in Solcjs with regards to how it handles the file names of output files generated by solc.

Here's what's happening:

Assuming we run solcjs cli like this on Linux/Mac:

$ solcjs --abi --bin -o some-folder path/to/file.sol

It'll generate:

some-folder/path_to_file_ContractName.abi
some-folder/path_to_file_ContractName.bin

Notice how slashes are replaced with underscores.

On windows however, often backslashes are used so the same command looks like this:

$ solcjs --abi --bin -o some-folder path\to\file.sol

However, writing the output fails because it doesn't replace backslashes with underscores. This is what it tries to write:

some-folder\path\to\file_ContractName.abi
some-folder\path\to\file_ContractName.bin

This won't work because path\fo\ doesn't exist inside some-folder.

I tested this with solc (instead of solcjs) and can confirm that it behaves correctly on Windows (replaces backslashes as expected).

I'm happy to look into this if this is fixable. I thought solcjs is only wrapping solc but maybe it does more to it.

Any ideas, pointers?

Hi, just wanted to follow-up and ask if anyone can give me direction to help fixing this.
