TaskFormatter/bash_task_formatter

BASH CLI Formatter with Spinner

This repository contains two scripts, task_formatter.sh and example_usage.sh, that work together to execute tasks with a spinner and formatted output. The task_formatter.sh script provides functions for running tasks with a spinner, while the example_usage.sh script demonstrates how to use these functions by defining and executing a set of tasks.

Example Output

Files

task_formatter.sh

This script contains functions for running tasks with a spinner and formatted output.

Functions

• spinner(pid): Displays a spinner while a background task is running.
• run_task(task_description, task_command): Executes a task with a spinner and captures its output.
• run_all_tasks(tasks): Runs all tasks passed as arguments, using the run_task function.

Usage

The task_formatter.sh script is designed to be sourced by another script, which can then call its functions to run tasks with formatted output.

example_usage.sh

This script demonstrates how to use the functions provided by task_formatter.sh to run a set of tasks.

Usage

1. Ensure both task_formatter.sh and example_usage.sh are executable:

   chmod +x task_formatter.sh
   chmod +x example_usage.sh
   

2. Run the example_usage.sh script:

   ./example_usage.sh
   

Example Tasks

The example_usage.sh script defines three example tasks:

• Task 1: Runs the sample_task function, which simulates a task running for 3 seconds.
• Task 2: Runs the another_sample_task function, which simulates a task running for 5 seconds and then returns an error.
• Task 3: Runs the sleep 2 command, which simulates a task running for 2 seconds.

How It Works

1. The example_usage.sh script sources the task_formatter.sh script to gain access to its functions.
2. The example_usage.sh script defines a set of tasks in an array, with each task specified as a description and a command separated by a colon (:).
3. The example_usage.sh script calls the run_all_tasks function from task_formatter.sh, passing the tasks as arguments.
4. The run_all_tasks function iterates over the tasks, splits each task into a description and a command, and calls the run_task function for each task.
5. The run_task function executes the task with a spinner and captures its output, displaying the task's status when it completes.

Spinner

The Spinner was adjusted from https://github.com/sindresorhus/cli-spinners

Example Output

Task 1 Running [⠼] [✔] Task 1 Completed 3s
Task 2 Running [⠧] [✘] Task 2 Error 5s

Error output:
Another sample task running

Task 3 Running [⠹] [✔] Task 3 Completed 2s
