Describe the bug
This variable declaration is valid Solidity and compiles correctly:
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
contract BrokenFmt {
uint256 public num =
// This is a comment
0;
}
However, forge fmt cannot parse it, and throws this error:
Failed to construct valid Solidity code for BrokenFmt.sol. Leaving source unchanged.
Debug info: [Diagnostic { loc: File(0, 143, 144), level: Error, ty: ParserError, message: "unrecognised token '0', expected \"!=\", \"%\", \"%=\", \"&\", \"&&\", \"&=\", \"(\", \")\", \"*\", \"**\", \"*=\", \"+\", \"++\", \"+=\", \",\", \"-\", \"--\", \"-=\", \".\", \"/\", \"/=\", \":\", \";\", \"<\", \"<<\", \"<<=\", \"<=\", \"=\", \"==\", \"=>\", \">\", \">=\", \">>\", \">>=\", \"?\", \"[\", \"]\", \"^\", \"^=\", \"calldata\", \"case\", \"constant\", \"days\", \"default\", \"error\", \"ether\", \"external\", \"gwei\", \"hours\", \"immutable\", \"indexed\", \"internal\", \"leave\", \"memory\", \"minutes\", \"override\", \"private\", \"public\", \"revert\", \"seconds\", \"storage\", \"switch\", \"weeks\", \"wei\", \"{\", \"|\", \"|=\", \"||\", \"}\", identifier", notes: [] }]
At the very least, it would be helpful to have a more helpful error message, but I believe forge fmt should be able to parse this given it compiles.
