I released a library. Compile Time Parser Generator.

@lefticus This is how you return nth argument to a function without recurrence:

[Piotr Winter @winter_dev]

@lefticus I think get_impl can be implemented such that it is not even recursive, which would improve the performance even more.

[Piotr Winter @winter_dev]

@ciura_victor @robwirving @cppcast @lefticus Wow. Now I can brag I was on the same podcast as Brian Kernighan:)

[Piotr Winter @winter_dev]

CTPG, new 1.3.7 version with couple of cool new features including:
- context parsing
- skip newline option
- 'construct' functor helper
- cleaned up CI and cmake build system

Also you can financially support me now if you like what I do:

@lefticus @daminetreg @beached_whale @ben_deane @foonathan I've dealt with in the json parser I created with ctpg. Just assumed max depth and max elements to be the number of characters.

[Piotr Winter @winter_dev]

@lefticus @beached_whale I've heard of somthing like ctpg, on some c++ podcast :)
Seriously, there is a ready for use constexpr json parser in the examples. I'm notsure what you mean by API compatibility.

[Piotr Winter @winter_dev]

@Jean_Blaguin_ I thought about properly adding ctpg to @CompileExplore , you know, in mythical 'spare time'...

[Piotr Winter @winter_dev]

Hi everyone.
Thanks to https://t.co/AQsj54pyAx now we can pass external context to the parser.

See for yourself:

@cppcast @lefticus @robwirving Thanks for a kind response to my project ❤️.
A very cool new feature in CTPG:

It was a pleasure. Thanks again @cppcast crew @lefticus and @robwirving.

Episode 332 of CppCast is live! In this episode @robwirving and @lefticus are joined by @winter_dev to talk about his #Cplusplus Compile Time Parser Generator! Listen Now! https://t.co/WXFSMy3jS2

[Piotr Winter @winter_dev]

@lefticus @kobi_ca @bretbrownjr @cppcast @robwirving and by 'tool' I ment c++ compiler not the parser generated with ctpg.

[Piotr Winter @winter_dev]

@kobi_ca @cppcast @lefticus @robwirving I'm using this Linux VM for my everyday job, not just ctpg related work :)

[Piotr Winter @winter_dev]

Finally we have msvc support.
Shiny new badge with windows build operational.

#ctpg

[Piotr Winter @winter_dev]

By popular demand I created a proper cmake build system for Compile Time Parser Generator.
So far gcc and clang are supported.
It should also be possible to use CTPG in other projects using cmake.

[Piotr Winter @winter_dev]

Actually, it compiles fast enough so simple examples started working on Compiler Explorer:

New version with clang support and much faster compilation times.

New major version of my Compile-Time Parser Generator is here:

Now with a shiny new error recovery feature:

Compile time parser generator. It generates LR(1) parser from a c++ code in compile time.
Lexical analyzer supports regex'es and converts them to a FSM.

[Piotr Winter @winter_dev]

Anyone interrested, please take a look at a simplified HTML parser example in CTPG.
https://t.co/0JKAW2HF2o
The fact that the parser is defined entirely in c++ allows interesting tricks, like auto generating terminals and rules.

@CharlesOfria Verbose mode is set in parse_options.
Diagnostic output is done through write_diag_str on the parser (last chapter in the readme). Diagnostic output is a detailed description of all possible parser and lexer states.
