Bash has 5 types of quoting: '...', "...", $'...', $"..." and backslash.
$'...' is a form of quoting,

This is reall
as i got suggested here for help-bash for new ..
there is ways to crop data to wanted by cropping the excludes out
but where is the simple way of keeping matching
i'd say implent backtrack references for @( .. ) etc groups
pseudo exmaple
declare -A big=( mess of data )
var=$( declare -p big )

i have currently no example
i tried converting assoc 2 arr and reverses, as for examples, with content
being weird filenames
that tries were a week ago or so, i ended up in loops instead of parsing
declare -p output sadly
but i demand extraction stuff, not just cutting away ... isnt it obvious ..
wheres the sense of not having same var format rules as.. normal, but not
for unset ?
i can do arr[$key]= without problems, cool, why bug around big in unset
( aka choose keywords instead of lower for, ... important functionality )

That's a feature request. Chet can discuss that with you.
All I can tell you is that this feature is not in an

that is, for no quotes
till non escaped end, ] probably
for " its till nonescaped "
and for $' till nonescaped '
i can regex it or extglob it

but i need the results of grouping of the matches ( '( .. )' )

as for goal, and no believance, it is handling quoting, string issues,
nothing else
you may know if you think about it im a freelance code there is nothing now
but major functionality issues

When using edit-and-execute-command to edit the command-line I've
noticed that PROMPT_COMMAND is not evaluated upon returning to the
prompt, e.g.:
earnest i ~ PROMPT_COMMAND='echo foobar'
foobar
earnest i ~ set -x
++ echo foobar
foobar
earnest c ~ # use edit-and-execute-com
well i have nothing against, excepts my .c is weak

Would this be the right place to discuss Readline as well as propose
features?
To not waste anyone's time, I'd also include an actual readline question
I have:
If readline is included in an ncurses software that also uses its own
keybindings for things, how would that work?
Does the software rec

It shouldn't be. Bash executes PROMPT_COMMAND before it calls readline to
read the first line of a command.

Yes, that's true, and makes sense when I think about it. But the
