Coloring cli output, screws up 'alignment'
Heyas

I'm trying to add color 'support' to my TUI.
It works, but behaves weird.

Code in question: (status.conf)
Code:
		R="\033[0m"
		r="\033[31m"
		y="\033[33m"
		p="\033[35m"
		g="\033[32m"
		b="\033[1m"

		TUI_TODO="[  ${p}${b}≡${R}   ]" 	;	TUI_WORK="[  ${y}${b}∞${R}   ]"
		TUI_DONE="[  $(printf ${g}${b}√${R})   ]" 	;	TUI_FAIL="[  ${r}${b}✗${R}   ]"

		TUI_SKIP="[  »   ]" 	;	TUI_NEXT="[  ⇒   ]"
		TUI_BACK="[  ⇐   ]" 	;	TUI_CANC="[  ✘   ]"
		TUI_ON="[  ◆   ]" 	;	TUI_OFF="[  ◇   ]"
		TUI_INFO="[ ⚠ⅈ⚠  ]" 	;	TUI_HELP="[ HELP ]"

The middleware: (tui-status)
Code:
#
#	Fill array according to return value
#
	unset retvalue[@]
	retvalue[0]="$TUI_DONE" ;	retvalue[1]="$TUI_FAIL"
	retvalue[2]="$TUI_WORK" ;	retvalue[3]="$TUI_TODO"
	retvalue[4]="$TUI_SKIP" ;	retvalue[5]="$TUI_NEXT"
	retvalue[6]="$TUI_BACK" ;	retvalue[7]="$TUI_CANC"
	
	retvalue[10]="$TUI_ON"	;	retvalue[11]="$TUI_OFF"
	
	retvalue[99]="$TUI_HELP";	retvalue[111]="$TUI_INFO"
#
#	Display
#	
	[[ -z "$1" ]] && ( tui-status 1 "Usage: tui-status ERRORLEVEL [ \"Message to user\" ]" ; exit 1)
	if [[ "$1" = "-h" ]]
	then	printf "
$ME ($script_version)
Usage: $ME \$? [ \"Message to user\" ]
Interpreted numbers:\n"
		for num in $(seq 0 1 120)
		do	str="${retvalue[$num]}"
			[[ ! "" = "$(printf '%s' $str)" ]] && \
				printf "\t$str : $num\n"
		done
		printf "\n"
		exit $RET_HELP
	else	if [[ ! "" = "${retvalue[$1]}" ]]
		then	case $count in	
			1)	tui-printf -E " " "${retvalue[$1]}"		;;
			2)	tui-printf -E "$2" "${retvalue[$1]}"		;;
			3)	tui-printf -E "$2" "$3" "${retvalue[$1]}"	;;
			4)	tui-status 1 "Too many args: $@"		;;
			esac
		else	tui-printf -E  "$2" "$3"  "ErrNr: $1"
		fi
	fi

I do not understand the mis-alignment of the colord values, they were placed proplerly (right aligned, like the lowest one) before that.
All other values still work, so its clear its 'just the colors' making the difference.

Any ideas please?
Thank you in advance

Whatever alignment code you use is considering these non-printing color chars as "printing" chars and giving them space accordingly.

Seems i need to move those functions to tui-printf, as tui-printf takes the 'status-value' as 'full' string including the color codes.
That way, i would only pass the exit code, and not the 'status string', thus reduce the 'expansion'/subtraction issue.

OH HOLY COW...
This was a headache, but worth it Smilie

At times it was fun to see how the arguments jumped along the lines... back and forth... dis- and reappearing.

When i wanted to share more code, i got the right train to the solution Smilie
Sorry.

(edit: took me like 2 hrs to write the post, aside of fixing code.. this one post was 3.. and now just edited due to the answer in between Smilie )

That looks a lot better. Glad I managed to guess right, even if a few hours too late Smilie

Yes it does, and thank you.
Sounds like my description or info provided was too less?
