makegrind is a tool to analyze the output from remake to profile make-based build systems. When remake is used with --profile=json the outputs can be parsed by makegrind using the NetworkX library.

The repository is compatible with setuptools. After cloning, run pip install path/to/makegrind and the appropriate dependencies should be installed.

After installing makegrind, it can be run with makegrind --input path/to/build/directory <COMMAND> where <COMMAND> determines which report to generate. Each command provides a --help argument to display possible options.

• summary: Generates a short summary with aggregated statistics
• paths: Generates listing of dependency path taking the longest time
• dirs: Generates statistics over each directory
• recipes: Generates statistics on recipes taking the longest time
• callgrind: Generates an aggregate callgrind.out.target file
• chrome-tracing: Generates an aggregate chrome-tracing.out.targets file
  • You can view this either by using chrome:https://tracing/ in your Chrome browser or visiting https://www.speedscope.app/.

Reports are yaml-formatted for easier parsing by other tools. Each report includes a few common keys.

• key: Can be used to identify the specific type of report
• name: An easily readable name for the report
• date: The initial start time of the build
