Right now it only works with solidity files that are in node_modules
or relative to your solidity file.
Simple usage:
npm i --save-dev sol-merger
Then add following line to your package.json.
{
"scripts": {
"build-contracts": "sol-merger \"./contracts/*.sol\" ./build"
},
}
This will allow you to use npm run build-contracts in your project directory.
Note that contracts glob should be surrounded with "
If no output file specified then output file will be created at the same
directory and appended with _merged (by default), i.e. MyContract_merged.sol. You can also
change this behaviour by specifying --append option:
sol-merger --append _me "./contracts/*.sol"
sol-merger -a _me "./contracts/*.sol"
You may need to use npm run to invoke the program standalone, as in npm run sol-merger.
You can also get help via --help command
sol-merger -h
sol-merger --help
