# uncrustify-0.80.1 is used to format cppcheck source code.
#
# 1. Download source code: https://github.com/uncrustify/uncrustify/archive/refs/tags/uncrustify-0.80.1.zip
#    It's important that all Cppcheck developers use the exact same version so we don't get a "format battle".
# 2. Building:
#    - Linux: mkdir build && cd build && cmake -DCMAKE_BUILD_TYPE=Release .. && make
#    - Windows: mkdir build && cd build && cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release .. && nmake
# 3. Ensure that the binary "uncrustify" is found by runformat. Either:
#    - you can put uncrustify in your PATH
#    - you can create an environment variable UNCRUSTIFY that has the full path of the binary
