parseExpression method

void parseExpression(JrlLine line, String source, RegExp expPresent)

Helper method to extract variables from the description. Helper method to extract variables from the valuta field. check if it can be evaluated with expressions: ^0.2.3: Parses expressions within the description or valuta fields. These expressions are stored in expressions and evaluated later.

Implementation

//void _extractVariablesFromDescription(JrlLine line, String desc) {
//  RegExp rex = RegExp(r"#(\w+)");
//  final matches = rex.allMatches(desc);
//  final extractedVariables = matches.map((match) => match.group(1)).toList();

//  // Store extracted variables in line.vars and the operation's `vars`.
//  for (final variable in extractedVariables) {
//    if (!vars.containsKey(variable)) {
//      vars[variable!] = variable;
//    }
//  }
//}
