Run ruby code, shell code, or customized tasks in parallel using worker processes/threads. You can dynamically pause/continue/increase/decrease the number of tasks using our UI.

WARNING this is a Work In Progress project:

• features are still being implemented
• API could and will change

It has been released so people can try it and make feature requests, comments and suggestions.

Feature Roadmap

Task definitions:

• define tasks from an YAML file
• tasks definition can include shell code or eval'ed ruby code
• tasks can also be defined with blocks of code, like RSpec.describe
• tasks can have dependencies that are needed to reach a goal, similar to rake, make, and others

Execution:

• tasks are executed in parallel, using worker processes/threads
• process are preferred on POSIX systems, otherwise threads are used
• default number of jobs is the # of real cpu cores on the system
• in case of task Error or Exception, the whole run will be stopped
• runner saves a log file in $(pwd)/fasten/log/runner/*name_of_runner*.log
• each task saves its STDERR/STDOUT to a log file in $(pwd)/fasten/log/task/*name_of_task*.log
• once finished, statistics are saved in $HOME/.fasten/stats/*name_of_runner*.csv, which include: status (DONE, FAIL), duration, average, stdev, error and count
• display a summary table of the execution

UI/Curses

• only available if the 'curses' gem is installed
• Display number of jobs running, idle, waiting, and number of jobs (max)
• Display current running tasks, pending tasks, waiting tasks, etc; showing which task is pending because other tasks need to be run first
• Display the number of tasks done/pending
• Display a progressbar
• Display current local time
• Pause whole runner with P key (waits current running tasks end)
• Resume paused runner with R key
• Press ⬅️ or ➡️ keys to dynamically increase/decrease number of jobs
• Use ⬆️ and ⬇️ to select tasks
• Calculate ETA, assuming all tasks take same time
• Calculate ETA, based on saved tasks statistics
• Live tail -f of selected tasks

UI/Console

• Console is the default if STDOUT/STDIN is not a tty
• Display each task as is being finished
• Calculate ETA, assuming all tasks take same time
• Calculate ETA, based on saved tasks statistics

CLI

• provides a CLI for running *_fasten.rb ruby code
