missing header memory_input.hpp

[Dr-Hex]

Compilation error on MS Visual Studio 2022.

Code:

#include "tao/json/from_string.hpp"

int main()
{
    auto json = tao::json::from_string("{}");
    return 0;
}

There is no such header file in pegtl repository (main branch):

#include <tao/pegtl/memory_input.hpp>

Reference:

json/include/tao/json/events/from_string.hpp

Line 9 in 11a31e1

#include <tao/pegtl/memory_input.hpp>

Right, memory_input does not exist on the main branch which at the moment (mostly?) corresponds with PEGTL version 4.0.0. So the PEGTL submodule here in taoJSON should point to the 3.x branch which is still the correct PEGTL version for tao JSON:

colin@mac:~/Source/Taocpp/json-main> git pull
Already up to date.
colin@mac:~/Source/Taocpp/json-main> git status
On branch main
Your branch is up to date with 'origin/main'.

nothing to commit, working tree clean
colin@mac:~/Source/Taocpp/json-main> cat .gitmodules 
[submodule "external/PEGTL"]
	path = external/PEGTL
	url = https://github.com/taocpp/PEGTL
	branch = 3.x
