Shellplate

A custom boilerplate for shell scripts

This boilerplate does not cover advanced scripting, but focuses more on automating a neat UI/UX for shell scripts.
As someone who occassionally creates shell scripts I made this oriented for self use, so feel free to edit all/any part of the code to match your own styles.
If you do use this code, please give me some credit in the repo :)

Features

• Neatly designed UI/UX
• Stores project data in a JSON file (project.json)
• Built-in dependency checker

Demo

You can find an example script built using Shellplate in the /example directory.

Dependencies

Shellplate depends on the following packages which need to be installed manually depending on your platform.

git
jq
curl
tput
fmt
figlet

These can also be found in requirements.txt

How to use

1. Open a terminal, clone this repo and cd into the Shellplate directory

    git clone https://github.com/DarkGuy10/Shellplate.git
    cd Shellplate
   

2. Execute the Shellplate.sh script and follow the interactive wizard

    bash Shellplate.sh
   

3. If during the dependency check, any of the packages are marked UNMET, manually install them and rerun the script.
4. Your project is created at out/<ProjectName>/. Open the <ProjectName>.sh file in the directory and place your code in the main() function.
5. Happy scripting!

Features in development

• Support for custom and prebuilt ANSII-based UI color schemes
• Built-in script updater
• Single script-file projects
• Script flags to skip the interactive wizard

Documentation

Project structure

<ProjectName>/
    ascii_art.txt
    <ProjectName>.sh
    project.json
    README.md
    requirements.txt

• ascii_art.txt - A banner art for the project created using figlet
• <ProjectName>.sh - This is the main script file. Put your code inside the main() function
• project.json - Contains basic info about the project. It follows the following template:

    {
      "name": "",
      "version": "",
      "author": "",
      "repository": "",
      "description": ""
    }
  

• README.md - The readme file of the project.
• requirements.txt - Contains a list of packages which the script depends to run. NOTE : Do not remove jq and tput from requirements.txt. They are important for the boilerplate itself.

UI/UX Utils

By default the <ProjectName>.sh script file contains a few utility functions for easier UI/UX management.

• pretty_banner - clears the screen and prints a banner showing project name ASCII art and other details
• centre "some text" - Print some text in centre of a region of 80 columns (80 is the maximum number of columns in the UI)
• header "some title" - Print a bold header in centre, bounded by []
