• Mustache implementation for modern C++ (requires C++11)
• Header only
• Zero dependencies
• Templated string type for compatibility with any STL-like string (std::string, std::wstring, etc)
• Boost license

All examples assume using namespace kainjow::mustache. Additional examples and usage can be found in the tests.cpp file.

mustache tmpl{"Hello {{what}}!"};
std::cout << tmpl.render({"what", "World"}) << std::endl;
// Hello World!

mustache tmpl{"{{#employees}}{{name}}, {{/employees}}"};
data employees{data::type::list};
employees << data{"name", "Steve"} << data{"name", "Bill"};
tmpl.render({"employees", employees}, std::cout);
// Steve, Bill,

mustache tmpl("Hello {{what}}!");
std::stringstream ss;
tmpl.render({"what", "World"}, [&ss](const std::string& str) {
    ss << str;
});
// ss.str() == "Hello World!"

This library supports all current Mustache features:

• Variables
• HTML escaping
• Sections
• Inverted Sections
• True/False
• Lists
• Lambdas
• Partials
• Comments
• Set Delimiter

Additional features:

• Custom escape function for use outside of HTML

For *nix:

make

For macOS:

make mac

For Visual Studio 2013 (CMake 2.8+ required):

build.bat

For Visual Studio 2015 (CMake 3.1+ required):

build.bat 14

• Lines with sections that result in an empty line are removed, per the Mustache spec.

• Add an overload to render() that accepts a context and a stream (thanks Kitsune Ral)
• Added checks for empty objects (thanks Snafuuz)
• Refactored parser in preparation for future changes

• Added ability to provide a custom escape function (thanks to Kitsune Ral)
• Allow data.set() to override an existing value

• Added a new lambda type (innovatively called lambda2) that takes an additional render function. It will not render its result but allows the user to call the render argument to render the section text, or any other text.

• Performance improvements - about 45% faster than version 2
• Even simpler API. Not backwards compatible but upgrading should be straightforward:
  • Namespace, classes, and methods are now in snake case to match the STL. For example, Kainjow::Mustache is now kainjow::mustache
  • Classes and aliases are now under a mustache namespace, instead of being under the mustache class
  • Removed Data::List() - use data{data::type::list} instead
  • Removed Data::type() - use the various is_xxx methods to identity the type

• New simpler API (not backwards compatible)
• std::wstring support
• Bug fixes (thanks to Shen-Ta Hsieh)
• Automated tests on OS X
• 100% test coverage

• All current Mustache features are implemented.
