$'...' and double-quotes

$'...' and double-quotes

[Bart Schaefer]

zsh% x="$'\012'"
zsh% echo $x
$'\012'

Hrm.

I would have thought $'...' acted like any other string-substitution when
inside double-quotes, i.e. like $(...) $[...] and $((...)) all do.  I
suppose the reason it doesn't work is because "'" is a quoted single
quote, not an ordinary single quote ...?

I'm not certain this needs to be changed, but I wanted to be sure it's
intentional.

bash has the same behaviour.

Prompt escapes RE: $'...' and double-quotes

[Andrej Borsenkow]

$'...' reminds me - is there any easy way to get prompt escapes embedded?
Manual for $'...' states, it the same as for print builtin - but print may
be forced to interpret prompt escapes as well.

In 3.1.6, ${(%)...}.  So these should be equivalent:

    print -P "${PS1}"
    print "${(%)PS1}"
