sol_support 0.1.0+2

Foundation library for the sol_pkgs Solidity compiler. Provides source locations, diagnostic collection, and import remapping.

sol_support

Universal foundation library for the sol_pkgs Solidity compiler.

Every other package in the monorepo depends on this one.

Features

Module	Description
SourceLocation	Byte-offset + length span in a source file
SourceMap	Fast binary-search conversion from offset → (line, column)
SourceUnit / SourceUnitRegistry	Tracks all source files in a compilation
Diagnostic / DiagnosticCollector	Error/warning/info collection with fatal-error short-circuit
ImportRemapping / ImportRemapper	[context:]prefix=target path rewriting (Foundry / Hardhat style)

Usage

import 'package:sol_support/sol_support.dart';

void main() {
  final registry = SourceUnitRegistry();
  final unit = registry.add('Adder.sol', '''
pragma solidity ^0.8.0;
contract Adder {
  function getSum(uint256 a, uint256 b) public pure returns (uint256) {
    return a + b;
  }
}
''');

  final lc = unit.locationOf(24);
  print(lc); // e.g. 3:1

  final diagnostics = DiagnosticCollector();
  diagnostics.warning('unused variable', location: SourceLocation(
    sourceIndex: unit.index,
    offset: 24,
    length: 3,
  ));
  print(diagnostics.diagnostics.first);
}

Severity	Meaning
info	Informational note
