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_
compdbaims to make it easier for you to run tools on your codebase by spoon-feeding you the right compile options.
compdbis not so much about generating the initial compilation database, this, is left to other tools, such as
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.
Standalone tools such as clang-tidy_ or text editors with libclang_ integration have to deal with compile options.
Examples of such tools, dealing with compilation databases are: irony-mode, rtags and ycmd_.
Based on this evidence,
compdbcame 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
Generate a compilation database with header files ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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
Running the tests ~~~~~~~~~~~~~~~~~
To run the tests, type::
python -m tests
For regression tests on a few open source projects::
cd tests/regression/headerdb make [all|help]
Contributions are always welcome!
