Oh boy, I'm sorry, just seen the link to MIG's echo...
Awesome, thank you!

I'm currently thinking about a 'catch' function for the type and which cases, and how to implement his solutions as a fallback.
Might even start with a locate and find if which should not be available - for 'general usage' -> for the swarm.sanity.env section Smilie

On the other hand....
Using his solution all along would help to ensure (a further step) same results all the way, regardless of whats on the system available.

Which would be a great thing, if it would work as I hoped Smilie
Code:
	echo_	"This is" 	"another piped" 	"test run" | printe -
	echo_e	"This is" 	"another piped" 	"test run" | printe -
	echo_n	"This is" 	"another piped" 	"test run" | printe -
	echo_en	"This is" 	"another piped" 	"test run" | printe -
	echo_q	"This is" 	"another piped" 	"test run" | printe -
	printf '%q ' "This is" 	"another piped" 	"test run" | printe -
	type echo_q

Outputs as:
Code:
# | This                                                 is                                another piped test run | #
# | This                                                 is                                another piped test run | #
# | This                                                 is                                another piped test run | #
# | This                                                 is                                another piped test run | #
# | This                                                 is                                another piped test run | #
# | This is                                         another piped                                        test run | #
echo_q ist eine Funktion.
echo_q () 
{ 
    printf '%q ' $*
}

But it should be like,
Code:
# | This is                                another piped                                                 test run | #

which only the 'hardcoded' printf '%q ' "str1" "str2" "str3" achieves.

Based on that, I tried this - to "partial" success...
Code:
echo_q () 
{ 
    printf '%q ' "$1" "$2" "$3"
}
# | testoutput                                           ''                                                    '' | #

Because of course I dislike the 2x2 single quotes...

All this isnt worth it - i give up on this, I guess I'll just do left orientations on pipes... saves alot of trouble, and that at least, I can achieve constistantly.

EDIT:
@ RudiC, yes, as of this post I've figured the link - before (so, in the previous posts) I just blindly did something.

EDIT2:
I mean... SWARM is for FREAKING END USER VISUALS...
"You" as a script author are supposed to make that certain... with piping some output, you cant promise a good interface to your enduser anyway (not with a 3 orientation output that is, obviously!!).

Also stuff like echo y | ask "question" is just stupid (in 'this' context) and has no practical use in/for SWARM...
Once you've used 'swarm' to browse within folders and execute stuff.. you'll understand why -> because writing that 'echo y n 1 3 15 n | <swarm based script cmdline>' takes as long as use those args upon the actual call... because if properly coded, you'd get the same result using the args that script should provide, without the need to pipe.

Granted, this is my bias based on the image/result I have in mind.

So again, I fell for standards - that really dont apply... GNARGH

I'm sorry, but i feel like that left, center and right for separate string orientation (read: "Work with 3 individual strings per line") is TOO MUCH for the current existing GNU/POSIX standards.
These are the kind of issues that caused my last "burnout".

Lets just put this under:
* Would be nice to have

And MIG, just to assure you, I've copied your echo_* functions as-is from your thread.
What I've 'quoted' was just additional trial adjustments. (for the pipes, still helpfull for general fallback usage! So again, thank you for those!)
