Some quick positive update - and a question:

The config file is written properly now (again).
For some reason (order), I had an issue to properly identify curl/wget and more/less, for the latter it used the fallback value 'cat'- while both, less and more were installed.. OMG...
Well, it all (that part) works now again as expected. Smilie


What currently confuses me, that it DOES print output (text), but neither swarm.print.border nor swarm.print.text seem to actualy get called...
By which I mean, they both SHOULD call swarm.update.geometry around which I placed set -x and set +x accordingly, yet, I dont see that part....
Code:
	swarm.print.border() { # MODE
	# Prints basic border for all lines, this should only be executed if COLUMNS > 25
	# The calling function has to handle the NEWLINE required by 'printe' (-E)
		swarm.protect "$FUNCNAME" "${@}" && exit 1
		# Makes no sense to print visuals on such short lines
		[[ ${COLUMNS} -lt 25 ]] && return 1

		local MODE="" #name=""
		case "${1/-}" in
		e|p)	MODE="basic"	;;
		h)		MODE="header"	;;
		t)		MODE="title"	;;
		esac

		# Make sure values are udpated
		set -x
		swarm.update.geometry
		set +x

		# Now prepare the seperate handling
		case "$MODE" in
		"basic")
			PRINT_LEFT_IN="$c_reset"
			PRINT_LEFT_OUT="${clrCL}${c_front}${c_back}"
			PRINT_RIGHT_IN="${c_front}${c_back}"
			pos_cor_num=0
			;;
		"header")
			local filler_num=$(( $numEND - $(( ${#BORDER_RIGHT} * 2 )) + 2 ))
			local filler_str=$($PRINTF "%*s" ${filler_num})
			PRINT_LEFT_IN="$filler_str" #$c_reset"
			PRINT_LEFT_OUT="${clrCL}${c_front}${c_back}"
			PRINT_RIGHT_IN="" #${c_front}${c_back}"
			pos_cor_num=0
			;;
		"title")
			local filler_num=$(( $(( $COLUMNS / 2 * 2)) - $(( ${#BORDER_RIGHT} * 2 )) + 2 ))
			local filler_str=$($PRINTF "%*s" ${filler_num})
			PRINT_LEFT_IN="${c_invert}$filler_str" #$c_reset"
			PRINT_LEFT_OUT="${clrCL}${c_front}${c_back}"
			PRINT_RIGHT_IN="${c_reset}${c_front}${c_back}"
			pos_cor_num=0
			;;
		esac

		# Get some numbers
		local identRight=$(( $lenRight + ${#clrCL}  ))
		local posLEFT="\33[$(( ${#BORDER_LEFT} - 2 ))G"
		local posRIGHT="\33[$(( $numEND - $lenRight - $pos_cor_num ))G"

		# Well, left aligned it works. isnt too hard
		$PRINTF "\r${PRINT_LEFT_OUT}${posLEFT}${BORDER_LEFT}${PRINT_LEFT_IN}" >&2

		# The right side is much more challenging
		$PRINTF "${posRIGHT}${PRINT_RIGHT_IN}${BORDER_RIGHT}${PRINT_RIGHT_OUT}${c_reset}" >&2
		$PRINTF "${posEND}"
	}

	swarm.update.geometry() { #
	echo " ------------- " >&2
		export COLUMNS="$($TPUT cols)"
		export LINES="$($TPUT lines)"

		# Set basic values
		export BORDER_LEFT="${SWARM_THEME_DATA[border-left]}"
		BORDER_RIGHT="${SWARM_THEME_DATA[border-right]}"	# Do not export just yet
		export clrFRONT="${SWARM_THEME_DATA[color-front]}"
		export clrBACK="${SWARM_THEME_DATA[color-back]}"

		# Check if border-right was set:
		[ -z "$BORDER_RIGHT" ] && \
				for((i=${#BORDER_LEFT}-1;i>=0;i--)); do BORDER_RIGHT="$BORDER_RIGHT${BORDER_LEFT:$i:1}"; done
		export BORDER_RIGHT

		# Get some numbers
		export lenLeft="${#BORDER_LEFT}"
		export lenRight="${#BORDER_RIGHT}"
		export lenClrFont=${#clrFRONT}
		export lenClrBack=${#clrBACK}
		export identRight=$(( $lenRight + ${#clrCL}  ))

		# Pre-Calculate positions
		export numHALF=$(( $COLUMNS / 2 ))
		export numEND=$(( $numHALF * 2 ))
		export posEND="\33[${numEND}G"
		# swarm.print.border still needs extra handling for posLEFT
		export posLEFT="\33[$(( $lenLeft + 2 ))G"

		# Set colors
		export c_front=$(swarm.color.fg ${SWARM_THEME_DATA[color-front]})
		export c_back=$(swarm.color.bg ${SWARM_THEME_DATA[color-back]})

		# If user wants extended logs, he shall have it
		! $isRO && $doLogExt && init.log "$SWARM_MSG_INIT_PID_GEOMETRY: ${PPID:-$PID}"
	}
	export -f swarm.update.geometry

Code:
[~/prjs/SWARM] 0 $ time  ./runtime

\033[7mWelcome to a short introduction\033[0m


SWARM is not supposed to be called like this.



Instead it is to be sourced by your script to get access to it's functions.




\033[7m\033[0m


When calling SWARM like you just did, you should provide arguments.
They are:
./runtime config

./runtime help
./runtime tarball


one


                                                                                                            [  ✓   ]

two

                                                                                                            [  âœ-   ]

real	0m0.079s
user	0m0.048s
sys	0m0.034s
[~/prjs/SWARM] 0 $

So, usualy, I would expect some ++ lines showing the working code, and the output of: echo " ------------- " >&2 from the update.geometry function itself...
But as you see, there is nothing.

Please, anyone has an idea as of: why?

Thank you in advance
