zsh 3.0.1 bug with named directories?

zsh 3.0.1 bug with named directories?

[Robert F Tobler]

I have been using the facility of zsh-3.0.0 to name directories by using a  
variable assignment:

	projects=/usr/local/projects

when I first introduced a number of these names in my .zshrc, they would not  
be considerd for completion with ~name before changing to this directory for  
the first time.  For this reason I set up the following function:

	namedir () { eval '$1=$2 ; if [[ ! -d ~$1 ]]; then unset $1 ; fi' }

and afterwards I could do:

	namedir projects /usr/local/projects
	namedir toolkits /usr/local/toolkits

and these names would then be considered for completion (forced by the d-)  
using ~projects or ~toolkits.

Now if I do the same in zsh 3.0.1, I get the following message:

	ray% namedir projects /usr/local/projects
	zsh: no such file or directory: projects=/usr/local/projects
	zsh: no such user or named directory: projects

Due to this and another problem (which I will post seperately) I have not  
installed zsh 3.0.1 yet.

This is on a i386-next-nextstep3 machine, zsh compiled with gcc 2.7.2.1.

Replace the single quotes with double quotes above and it'll work.  It
seems that you original intention was to eval the expanded string but
strings within single quotes are not expanded.  In zsh-3.0.0
$1=$2 worked as an assignemt but it was a bug and it does not work
anymore.

E.g. this should work:

	namedir () { eval $1=\$2 ; if [[ ! -d ~$1 ]]; then unset $1 ; fi }
