constructing a zsh array from a specific tree structure

Hi,

I want to construct a zsh array using a tree structure as a source. like so:


zsh $ tree -L 2
.
|-- ninrod
| |-- docker-compose-zsh-completion
| |-- docker-zsh-completion
| |-- k
| `-- zsh-bd
|-- seebi
| `-- dircolors-solarized
|-- zdharma
| `-- fast-syntax-highlighting
`-- zsh-users
|-- zsh-completions
`-- zsh-history-substring-search

12 directories, 0 files
zsh $


from this structure, I want to construct this array:

plugin_paths+=(ninrod/docker-zsh-completion)
plugin_paths+=(ninrod/docker-compose-zsh-completion)
plugin_paths+=(ninrod/zsh-bd)
plugin_paths+=(zsh-users/zsh-completions)
plugin_paths+=(zdharma/fast-syntax-highlighting)
plugin_paths+=(ninrod/k)

is there a way to do that in zsh?

thanks in advance,

Filipe Silva

What's the rule?  Why is zsh-users/zsh-completion there and
seebi/dircolors-solarized not?

I'm guessing you want:
.
    plugin_paths+=( */*/.git(N:h) )

or:
.
    typeset -aU plugin_paths
    plugin_paths+=( */*/*.plugin.zsh(N:h) )

Explanation: */*/.git expands to the names of all directories named foo/bar/.git.
If there are none, it will append nothing, because of the (N) qualifier
(otherwise an error would have been raised).  The (:h) qualifier drops the last
path component, leaving just foo/bar.  The second solution is similar, but
uses the -U flag to make the array unique, in case the glob has more than
one match in a single directory.

Cheers,

Daniel
