for loop with parameter expansion in zsh vs. bash

[Alexander Skwar <alexanders.mailinglists+nospam@xxxxxxxxx>]

Hello

I've got a variable, where seperate values are limited with a delimiter.
Let's say PATH with : (but the question is general).

With bash, I can easily create a for loop which loops over all the
elements, when I have bash replace the ":" with a " ", like so: ${PATH//:/
}.

a@ubuntu-notebook:~$ echo $PATH
/home/a/Applications/go/bin:/home/a/bin:/opt/bin:/opt/sbin:/usr/local/sbin:/usr/local/bin:/home/a/Applications/copy/x86_64:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/home/a/Applications/adt-bundle-linux-x86_64/sdk/platform-tools:/home/a/Applications/btsync:/home/a/.rvm/bin

a@ubuntu-notebook:~$ for e in ${PATH//:/ }; do echo e: $e; done
e: /home/a/Applications/go/bin
e: /home/a/bin
e: /opt/bin
e: /opt/sbin
e: /usr/local/sbin
e: /usr/local/bin
e: /home/a/Applications/copy/x86_64
e: /usr/sbin
e: /usr/bin
e: /sbin
e: /bin
e: /usr/games
e: /usr/local/games
e: /home/a/Applications/adt-bundle-linux-x86_64/sdk/platform-tools
e: /home/a/Applications/btsync
e: /home/a/.rvm/bin


In zsh, the same for loop does not work (like it does in bash):

7:51% for e in ${PATH//:/ }; do echo e: $e; done
e: /home/a/Applications/go/bin /home/a/bin /opt/bin /opt/sbin
/usr/local/sbin /usr/local/bin /home/a/Applications/copy/x86_64 /usr/sbin
/usr/bin /sbin /bin /usr/games /usr/local/games
/home/a/Applications/adt-bundle-linux-x86_64/sdk/platform-tools
/home/a/Applications/btsync


As you can see there, zsh had only 1 iteration of the for loop.

What would be the zsh way to loop over elements, which are delimited by a
":" (or "," or ";" or whatever)?

Thanks a lot,



Alexander
