Hmm, no idea which subsystem to use here 🤔. I see that previous commits in these files were marked as |
| auto first = input.front(); | ||
| if ((first == '\'' || first == '"' || first == '`') && | ||
| input.back() == first) { | ||
| input = input.substr(1, input.size() - 2); |

A more readable way:
input.remove_prefix(1);
input.remove_suffix(2);
|

| void Dotenv::ParseContent(const std::string_view input) { | ||
| std::string lines(input); | ||
| std::string_view parse_key(std::string_view key) { |

Can you add a comment to what this function does?
| // Expand \n to newline in double-quote strings | ||
| size_t pos = 0; | ||
| auto expanded = std::string(trimmed); | ||
| while ((pos = expanded.find("\\n", pos)) != std::string_view::npos) { |

expanded is a string now. std::string::npos is the correct return value here.
| if (value.empty()) return ""; | ||
|
|
||
| auto trimmed = trim_quotes(value); | ||
| if (value.front() == '\"' && value.back() == '\"') { |

Can you add a documentation to here?
Returning the else statement early will make this function much more readable.
| std::string::size_type start = 0; | ||
| std::string::size_type end = 0; | ||
|
|
||
| for (std::string::size_type i = 0; i < input.size(); i++) { |

You removed all of the comments in this function, and it is a lot less readable right now. I can't review it with the current state.

This is basically a new function. Old one was doing a lot of back & forth searching for chars and newlines in string and it was hard for me to fit in a fix. This goes through the content of file only once and parses it char by char.

This can return std::string_view since the underlying store will not be disposed.

Hey @anonrig did you have a chance to take a second look? I've resolved all small things and only thing left is the parsing function that I have rewritten. If you think that the change is too risky I can revert it, keep the tests and try to fit in the fix in current implementation. |
