mecho is marked up echo. It's a shell function for printing colored and formatted text to the terminal using a simple markup.

mecho "A [red]rose[/] is a [bg_red]rose[/] is a [red][bold][bg_yellow]rose[/]"

Or alternatively

# use it like 'echo' with no quotes
mecho boredom [bg_green]unto[/] freedom
# suppress newline at the end with the -n flag
mecho -n "[yellow][bold](User: zer0Cool)[/]"

Just copy the mecho function into your shell's rc file. Here it is, in full, for bash:

mecho() {
  colors=(black red green yellow blue purple cyan white)
  effects=(reset bold dim italic underline blink rblink reverse)
  if [ "$1" == "-n" ]; then nl=0; shift; else nl=1; fi
  M="$*"; M=${M//\[\/\]/\[reset\]}
  for i in "${!colors[@]}"; do
    M=${M//\[${colors[$i]}\]/\\033[0;3${i}m}
    M=${M//\[bg_${colors[$i]}\]/\\033[4${i}m}
    M=${M//\[${effects[$i]}\]/\\033[${i}m}
  done
  printf -- "$M"
  if [ "$nl" -eq 1 ]; then printf "\n"; fi
}

Also in this repo is the zsh version.

Much like, echo, mecho takes any number of arguments and prints them to standard output, interpreting a simple markup syntax of [tags] to colors and effects, with an optional newline at the end. The tags are in the form [tag] and [/] to reset.

Colors: black, red, green, yellow, blue, purple, cyan, white

Effects: reset, bold, dim, italic, underline, blink, rblink, reverse

To make a background color, prefix the color with bg_.

To suppress the newline at the end, use the -n flag.

To stack tags, just put them in order, like [color][effect][bg_color]

Markup inspired by rich, in turn inspired by BBCode.
