I'm looking for endorsements and a review manager volunteer for
a new library, Boost.Mustache. It's an implementation of Mustache
templates (http://mustache.github.io/) in C++11 and at the moment
supports the mandatory portions of the Mustache spec
(https://github.com/mustache/spec).
The repository is https://github.com/pdimov/mustache.
Mustache is a simple templating language in which tags of the form
{{something}} are replaced with the value of the entity `something`, which
typically means with the member "something" of the JSON object passed
when rendering the template.
Boost.Mustache can take a Boost.JSON object as the context against which
data references are resolved, but it can also take arbitrary values that can
be converted to boost::json::value by using boost::json::value_from.
This allows, for instance, described classes (structs and classes annotated
with Boost.Describe) to be passed as the data context, such that references
to e.g. {{title}} in the template are resolved to the corresponding `title`
member of the class.
A simple usage example demonstrating the above is:
```
#include
#include
#include <iostream>
struct item
{
std::string title;
std::string author;
std::string link;
};
BOOST_DESCRIBE_STRUCT(item, (), (title, author, link))
struct reference
{
std::string heading;
std::vector<item> items;
};
BOOST_DESCRIBE_STRUCT(reference, (), (heading, items))
int main()
{
reference ref =
{
"Reference",
{
{
"Better Bit Mixing - Improving on MurmurHash3's 64-bit Finalizer",
"David Stafford",

},
{
"Stronger, better, morer, Moremur; a better Murmur3-type mixer",
"Pelle Evensen",
"https://mostlymangling.blogspot.com/2019/12/stronger-better-morer-moremur-be..."
},
{
"Improved mx3 and the RRC test",
"Jon Maiga",
"http://jonkagstrom.com/mx3/mx3_rev2.html"
}
}
};
std::string tmpl =
R"(<html>
<body>
<h1>{{heading}}</h1>
<ul>
{{#items}}
<li>
<strong>{{title}}</strong><br>
<em>{{author}}</em><br>
<a href="{{link}}">{{link}}</a>
{{/items}}
</ul>
</body>
</html>)";
boost::mustache::render( tmpl, std::cout, ref, {} );
}
```
The resulting output is
<html>
<body>
