4-6: TODO and NOLINTNEXTLINE present despite PR objective to remove themThe PR objectives mentioned removing all
NOLINTcomments, but there's still aNOLINTNEXTLINEcomment here. Consider addressing the TODO item in a separate PR or updating the current PR's objectives to clarify that some TODOs and NOLINT comments will remain.
48-49: Method formatting inconsistencyThe
read_to_delimitermethod declaration spans two lines with a different formatting style than other methods. Consider making the formatting consistent across all methods.- [[nodiscard]] virtual auto - read_to_delimiter(char delim, bool keep_delimiter, bool append, std::string& str) -> ErrorCode; + [[nodiscard]] virtual auto read_to_delimiter(char delim, bool keep_delimiter, bool append, std::string& str) + -> ErrorCode;
80-82: TODO and NOLINTNEXTLINE still presentSimilar to the earlier TODO, there's another one here with a NOLINTNEXTLINE comment. Consider addressing this in a separate PR or updating the current PR objectives.

16-25: Good addition of special member functions with proper semanticsThe class now properly defines its special member functions following the rule of five. Deleting copy operations and enabling move operations is a good practice for resource-owning interfaces, especially ones that might be used in containers or transferred between objects.
31-39: Improved method signature with[[nodiscard]]and error code returnThe method signature change from returning
boolto returningErrorCodewith the[[nodiscard]]attribute aligns well with the PR objective of enhancing error handling. This ensures errors aren't accidentally ignored.
56-56: Good removal ofeof_possibleparameterThe removal of the
eof_possibleparameter fromread_exact_lengthaligns with the PR objective of eliminating these flags in favor of returning EOF-related error codes directly.
62-62: Good template method alignment with error code approachThe
read_numeric_valuemethod now correctly returns anErrorCodeand includes the[[nodiscard]]attribute, consistent with the pattern applied to other methods in the class.
68-68: Good removal ofeof_possibleparameter fromread_stringSimilar to
read_exact_length, removing theeof_possibleparameter fromread_stringaligns with the PR objective of returning EOF-related error codes directly.
74-74: Trailing return type forseek_from_beginThe signature change for
seek_from_beginto returnErrorCodeis good, consistent with the other methods.
87-87: Good method signature update forget_posChanging
get_posto return anErrorCodeand take a reference parameter for the position aligns well with the error handling approach. This provides a clear way to handle errors when retrieving the current position.
91-92: Template method implementation now uses error codeThe implementation of
read_numeric_valuenow correctly uses and returns theErrorCodefromread_exact_length. This is a good change that aligns with the overall error handling approach.
