The value of ${foo=right-hand-side} is the value of right-hand-side, after applying all the expansion flags, not the value of $foo. Thus ${#...} counts right-hand-side, and the shwordsplit of a word with no spaces is a scalar, not an array, so the number of characters results. However, this turns out to be ridiculously easy to change so that the code matches the implication of the doc for ${NAME=WORD}. diff --git a/Src/subst.c b/Src/subst.c index 99e1650..c61551b 100644 --- a/Src/subst.c +++ b/Src/subst.c @@ -2897,6 +2897,7 @@ paramsubst(LinkList l, LinkNode n, char **str, int qt, int pf_flags, aval = paramvalarr(pm->gsu.h->getfn(pm), hkeys|hvals); } else setaparam(idbeg, a); + isarr = 1; } else { untokenize(val); setsparam(idbeg, ztrdup(val)); diff --git a/Test/D04parameter.ztst b/Test/D04parameter.ztst index 460a841..37166fa 100644 --- a/Test/D04parameter.ztst +++ b/Test/D04parameter.ztst @@ -82,6 +82,11 @@ >wasnull2d >wasnull2d + unset array + print ${#${(A)=array=word}} +0:${#${(A)=array=word}} counts array elements +>1 + (print ${set1:?okhere}; print ${unset1:?exiting1}; print not reached;) (print ${null1?okhere}; print ${null1:?exiting2}; print not reached;) 1:${...:?...}, ${...?...}
