compdb

Tools for working with compile_commands.json.

Installation

CARGO_NET_GIT_FETCH_WITH_CLI=true cargo install --git https://github.com/korniltsev-grafanista/compdb.git filter
CARGO_NET_GIT_FETCH_WITH_CLI=true cargo install --git https://github.com/korniltsev-grafanista/compdb.git cc

This installs three binaries:

• compdb-filter - Filter compile_commands.json by regex patterns
• compdb-cc - C compiler wrapper for generating compile_commands.json
• compdb-cxx - C++ compiler wrapper for generating compile_commands.json

compdb-filter

Filter compile_commands.json by regex patterns.

Usage

compdb-filter [OPTIONS] [PATH]

Arguments

• PATH - Path to compile_commands.json (default: ./compile_commands.json)

Options

• -e, --exclude <REGEX> - Exclude files matching this regex (can be repeated)
• -i, --include <REGEX> - Include files matching this regex even if excluded (can be repeated)

compdb-cc / compdb-cxx

Compiler wrappers that log compilation commands for generating compile_commands.json.

How It Works

1. compdb-cc and compdb-cxx act as drop-in replacements for your C/C++ compiler
2. They log each compilation command to a file
3. After the build completes, run with --generate to create compile_commands.json

Environment Variables

Variable	Required	Description
COMPDB_LOG	Yes	Absolute path to the log file (e.g., /tmp/compdb.log)
COMPDB_CC	No	C compiler to use (default: clang)
COMPDB_CXX	No	C++ compiler to use (default: clang++)
COMPDB_GENERATE	No	Set to any non-empty value to generate compile_commands.json

Usage

# Set up environment
export COMPDB_LOG=/tmp/compdb.log
export COMPDB_CC=gcc
export COMPDB_CXX=g++

# Build your project using the wrappers as compilers
./configure CC=compdb-cc CXX=compdb-cxx
make

# Generate compile_commands.json
compdb-cc --generate
