Tomo::Logger

Provides a simple interface for logging messages to stdout and stderr. In multi-host deployments, messages are automatically prefixed with [1], [2], etc. based on current host. This makes it easier to distinguish where log messages are coming from.

$ tomo run bundler:clean
tomo run v0.1.0
[1] → Connecting to deployer@web1.example.com
[2] → Connecting to deployer@web2.example.com
[1] • bundler:clean
[2] • bundler:clean
[1] cd /home/deployer/apps/my-app/current && bundle clean
[2] cd /home/deployer/apps/my-app/current && bundle clean
✔ Ran bundler:clean on deployer@web1.example.com and deployer@web2.example.com

If tomo is run in --dry-run mode, log messages are prefixed with a * to indicate the commands are being simulated.

$ tomo run bundler:clean --dry-run
tomo run v0.1.0
* [1] → Connecting to deployer@web1.example.com
* [2] → Connecting to deployer@web2.example.com
* [1] • bundler:clean
* [2] • bundler:clean
* [1] cd /home/deployer/apps/my-app/current && bundle clean
* [2] cd /home/deployer/apps/my-app/current && bundle clean
* Simulated bundler:clean on deployer@web1.example.com and deployer@web2.example.com (dry run)
