The tree printed by lexy::trace shows successful parsing, but still reports errors.

[Life4gal]

I am using lexy to write a simple ini file parsing library, it works fine, but there is a problem.

My intention is to support optional value (key is necessary) and optional inline comment.

In order not to have the comment starters (; and #) be considered part of the value, my value looks like this:

This allows adding inline comment after a key-value pair that has no value.

But this presents a problem, as the title suggests.

And it does fail, because the key4 line does not repeatedly write # foo bar baz here as the other lines do.

If you need further information, please contact me. :)

That seems like a bug. Can you share a playground example that reproduces it? https://lexy.foonathan.net/playground/

[Life4gal]

Please give me a C++ source files that contains

• The input as a string literal.
• A call to lexy::trace that works as expected.
• A call to lexy::parse that fails.

I can't really help you otherwise.

unit_test/src/test_flusher.cpp

That file contains a bunch of other code. It also isn't at all clear how it generates the input and where the actual call happens. I want something like:

#include <ini/foo.hpp>

int main()
{
     auto input = "...";
     
     lexy::trace(...);
     lexy::parse(...);
}

I will try, but it may be a bit complicated, I now suspect because there are some unexpected differences between my flusher and extractor's grammar.

[Life4gal]

After testing, I'm sure it's the inconsistent grammar of extractor and flusher that's causing the problem. :)

Let me know if you need my help with anything.
