#!/usr/bin/env bash

## Purpose: This script is used to run all the necessary checks and
## tests for the project.

## Fail on any error:
set -e

## Declare default styles:
_sty_bold=""
_sty_underline=""
_sty_standout=""
_sty_normal=""
_sty_black=""
_sty_red=""
_sty_green=""
_sty_yellow=""
_sty_blue=""
_sty_magenta=""
_sty_cyan=""
_sty_white=""

## Set styles if we are on terminal:
if test -t 1; then
    ## Check if the terminal supports colors:
    ncolors=$(tput colors)

    ## Defines styles:
    if test -n "$ncolors" && test "${ncolors}" -ge 8; then
        _sty_bold="$(tput bold)"
        _sty_underline="$(tput smul)"
        _sty_standout="$(tput smso)"
        _sty_normal="$(tput sgr0)"
        _sty_black="$(tput setaf 0)"
        _sty_red="$(tput setaf 1)"
        _sty_green="$(tput setaf 2)"
        _sty_yellow="$(tput setaf 3)"
        _sty_blue="$(tput setaf 4)"
