# more details: http://clang.llvm.org/docs/JSONCompilationDatabase.html | |

# 'flags' list of compilation flags. Notice that YCM itself uses that approach. | |

# THIS IS IMPORTANT! Without a "-std=<something>" flag, clang won't know which | |
# language to use when compiling headers. So it will guess. Badly. So C++ | |
# headers will be compiled as C headers. You don't want that so ALWAYS specify | |
# a "-std=<something>". | |
# For a C project, you would set this to something like 'c99' instead of | |
# 'c++11'. | |
'-std=c++11', | |
# ...and the same thing goes for the magic -x option which specifies the | |
# language that the files to be compiled are written in. This is mostly | |
# relevant for c++ headers. | |
# For a C project, you would set this to 'c' instead of 'c++'. | |
