wucc

wucc - whs31's utilities and compilers collection

What is wucc?

wucc is basically a multi-tool for me and my team. It contains a bunch of useful tools and "compilers" (template generators) for C++ development and some other stuff.

Examples

Compile JSON files to a C++ header file

wucc json-to-cpp file1.json file2.json file3.json \
  -O . \
  -o header \
  --namespace my::namespace_ \
  --nlohmann
  
cat header.json.h

Output:

/*
 * Generated by the whs31's ucc compiler (wucc)
 * Source file(s):
 *   - file1.json
 *   - file2.json
 *   - file3.json
 *
 * File stem: header

        [[maybe_unused]]
        static inline auto file3_json = nlohmann::json::parse(file3_c_str);
    } // namespace file3

Compile YAML files to a C++ header file

wucc yaml-to-cpp file1.yaml file2.yaml file3.yaml \
  -O . \
  -o header \
  --namespace my::namespace_ \
  --nlohmann
  
cat header.yml.h
