Function documentation

tk::FileParser::FileParser(const std::string& filename) explicit protected

Constructor.

Parameters
filename in	File to be parsed by the parser

This constructor does basic tests in an attempt to determine if the file to be parsed exists and is in good shape and does associated error handling. This file stream is local, only used for error checking, and thus is not part of the object state here since the parser, inheriting from FileParser, e.g., walker::InputDeckParser, parses by completely outsourcing the parsing (to PEGTL), so there is no need to store the file stream handle here.

void tk::FileParser::diagnostics(const tk::Print& print, const std::vector<std::string>& messages) protected

Echo errors accumulated during parsing.

Parameters
print in	Pretty printer
messages in	Vector of strings of errors and warnings

< number of digits of line num

< original line parsed

< underline

< error or warning messages
