# Script to generate compile_commands.json based on Makefile output
# Works by accepting Makefile output from stdin, parsing it, and
# turning into json records. These are then printed to stdout.
# More details on the compile_commands format at:
# https://clang.llvm.org/docs/JSONCompilationDatabase.html
#
# Note: make must be run in verbose mode, e.g. V=1 make or VERBOSE=1 make
#
# Usage with node-cpp-skel:
#
# make | ./scripts/generate_compile_commands.py > build/compile_commands.json
# These work for node-cpp-skel to detect the files being compiled
# They may need to be modified if you adapt this to another tool
