The compilation database Swiss army knife
compdb is a command line tool to manipulates compilation databases. A compilation database is a database for compile options, it has records of which compile options are used to build the files in a project. An example of compilation database is the JSON Compilation Database
compdb aims to make it easier for you to run tools on your codebase by spoon-feeding you the right compile options.
compdb is not so much about generating the initial compilation database, this, is left to other tools, such as cmake and ninja. It is only a glue between the initial compilation database and your tool(s).
With the proliferation of Clang-based tools, it has become apparent that the compile options are no longer useful uniquely to the compiler.
Based on this evidence, compdb came to life. A tool that has knowledge of the compile options and can share it both to inform the text editor and to run clang based tool from the shell.
Install with pip:
pip install compdb
From Github, as user:
pip install --user git+https://github.com/Sarcasm/compdb.git#egg=compdb
Assuming a build directory build/, containing a compile_commands.json, a new compilation database, containing the header files, can be generated with:
compdb -p build/ list > compile_commands.json
To run the tests, type:
python -m tests
For regression tests on a few open source projects:
cd tests/regression/headerdb make [all|help]
