Inja is a template engine for modern C++, loosely inspired by [jinja](http://jinja.pocoo.org) for python. It has an easy and yet powerful template syntax with all variables, loops, conditions, includes, callbacks, comments you need, nested and combined as you like. Inja uses the wonderful [json](https://github.com/nlohmann/json) library by nlohmann for data input and handling. Most importantly, *inja* needs only two header files, which is (nearly) as trivial as integration in C++ can get. Of course, everything is tested on all relevant compilers.

## Supported compilers
Currently, the following compilers are tested:
Inja uses `string_view` from C++17, everything else should work with C++11. Currently, the following compilers are tested:
- GCC 4.9 - 7.1 (and possibly later)
- Clang 3.6 - 5.0 (and possibly later)
- Microsoft Visual C++ 2015 / Build Tools 14.0.25123.0 (and possibly later)
- GCC 7.0 - 8.0 (and possibly later)
- Clang 6.0 (and possibly later)
- Microsoft Visual C++ 2017 / Build Tools 15.1.548.43366 (and possibly later)

# This is intended to be run by a custom target in a CMake project like this.
# 0. Compile program with coverage support.
# 1. Clear coverage data. (Recursively delete *.gcda in build dir)
# 2. Run the unit tests.
# 3. Run this script specifying which source files the coverage should be performed on.
#
# This script will then use gcov to generate .gcov files in the directory specified
# via the COV_PATH var. This should probably be the same as your cmake build dir.
#
# It then parses the .gcov files to convert them into the Coveralls JSON format:
# https://coveralls.io/docs/api
#
# Example for running as standalone CMake script from the command line:
# (Note it is important the -P is at the end...)
