ssh-config hosts sections for autocompletion

[elias5000]

Autocompletion plugin for people who like to make extensive use of ssh-config.
Autocompletion for clouds tool (https://github.com/cristim/clouds).

Is this doing something more than the default Zsh hosts completion?

[elias5000]

Zsh completion does offer hosts that are in the known_hosts file but not hosts from the ssh-config.

I just confirmed that completion from ~/.ssh/config is working with a vanilla Zsh install (Ubuntu package version 4.3.17, without OMZ installed of course). Can you confirm that Zsh does not complete from ~/.ssh/config on your machine, and share your configuration?

I just browsed quickly through Zsh completion code, and I could not find where this is done, but ~/.ssh/config is definitely parsed for ssh completion. Will look into it later.

I'm using zsh 5.0.2 (x86_64-apple-darwin13.0) on Mavericks and can confirm that /etc/hosts and known_hosts are completed but ssh-config host sections are not offered for completion.

@ncanceill: I think you want the _ssh completion function, and specifically its _ssh_hosts helper function which is where it reads the ssh-config file.

I'm also running zsh 5.0.2 on Mavericks, and entries from ssh-config host section names are offered for completion... in some cases. Maybe we should look a bit closely at the default and target behavior before merging this in.

Switching over to #2707 for further comments.

Since you have two separate plugins, maybe you should also have two separate PRs?

[elias5000]

Sorry for the mixed PR. It basically is my second PR and I gave up on trying to find out how to cherry-pick the change to put into the PR.

[elias5000]

I closed the PR and will open two separate ones for the plugins.
