Unfolds all local imports in a solidity file to generate a flat solidity file.
Manually combining all imports in a solidity file when verifying your contract source on Etherscan is time-consuming and cumbersome. This tool automatically traverses the dependency graph of imports and combines them in the correct order, which is ready to be pasted into the contract verifier.
NOTE: This tool won't work with imports that are aliased (i.e. import "./foo.sol" as bar; )
There are no requirements for this tool.
pip install solidity-unfolder
usage: solu [-h] [-o *.sol] *.sol *.*.*
Unfolds all local imports in a solidity file to generate a flat solidity file.
Put the output file into out/ folders.
positional arguments:
*.sol target filename with imports
*.*.* solidity compiler version e.g. 0.4.24
optional arguments:
-h, --help show this help message and exit
-o *.sol, --output *.sol
output filename (default: flat.sol)
solu contract-with-imports.sol 0.4.24
It will output flat.sol (default output filename) with solidity version 0.4.24 in out/ folder.
solu contract-with-imports.sol 0.4.20 --output contract-flat.sol
It will output contract-flat.sol with solidity version 0.4.20 in out/ folder.
