Question 1

How to add Jinja2C++ to my CMake project?

Accepted Answer

Use the provided CMake scripts or conan.io package. Set variables like JINJA2CPP_DEPS_MODE and link the library, with examples in the documentation for different build configurations.

Question 2

Jinja2C++ vs Python Jinja2 for C++ code generation?

Accepted Answer

Jinja2C++ eliminates Python runtime dependency in C++ projects, but if your stack already includes Python, native Jinja2 might be easier to integrate and more feature-complete.

Question 3

Does Jinja2C++ support custom C++ data types?

Accepted Answer

Yes, through built-in reflection for common types or user-defined callables. You can extend it to handle custom structs and classes in templates.

Question 4

What filters and tests are missing in Jinja2C++?

Accepted Answer

Check the compatibility table in the docs; while it supports many like 'map' and 'select', some edge-case filters from Jinja2 may not be implemented yet.

Question 5

How fast is Jinja2C++ for rendering HTML in a web server?

Accepted Answer

It includes template caching for performance, but benchmark rendering times as the engine adds overhead; for high-throughput scenarios, consider profiling.

Question 6

Can I use Jinja2C++ with C++17 or newer standards?

Accepted Answer

Yes, it supports C++14, C++17, and C++20, using standard types like std::variant where possible, as noted in the compiler support section.

Question 7

How to debug template errors in Jinja2C++?

Accepted Answer

Leverage the rich error reporting feature, which provides detailed messages on syntax and runtime issues, similar to Python Jinja2's error output.
