Tracemake

A tool to trace make command execution and convert it to Chrome Tracing format. This gem allows tracking the execution time of each command in a make process.

Installation

Add this line to your application's Gemfile:

gem 'tracemake'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install tracemake

Usage

1. Run make with this gem as the shell:

make SHELL="tracemake shell" -j8

2. Convert the trace to Chrome Tracing format:

tracemake aggregate -o make-trace.json

3. Open the resulting JSON file in Chrome's chrome://tracing or https://ui.perfetto.dev/

You can download a sample trace from here to try it out.

The trace file will be created in the current directory as .make.trace. You can override this location by setting the TRACE_FILE environment variable:

TRACE_FILE=/path/to/trace make SHELL="tracemake shell" -j8

Note

When running multiple make commands in sequence, make sure to remove the .make.trace file before each run to avoid mixing traces from different make processes:

rm -f .make.trace
make SHELL="tracemake shell" -j8

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
