compile_commands.json is a JSON format compilation database. It maintains a list of sources with their build options.
OCLint can leverage the information from this file to facilitate the inspection process.
oclint-json-compilation-database helps extract and filter information from compile_commands.json, and invoke OCLint under the hook for analysis.
