Add support for oh-my-zsh plugin.

[alxbl]

Thanks for making this project, it's really cool! I'd been looking for something like this for a while.
I noticed that your shell widget is pretty much stand-alone and I wanted to be able to use navi directly as an oh-my-zsh plugin, so I added a few things to the widget and moved it to the root of the repository so that the repo can be cloned straight into the plugins folder and detected when added in the plugin array.

I think it should be similarly simple with fish, but I'm not too familiar with that shell, so I'll leave it to someone else. The navi.plugin.zsh file should still be sourcable as a widget for people not using oh-my-zsh, so technically the shell/ directory could be removed and navi widgetupdated to use the new file.

What's included

• oh-my-zsh plugin
• install documentation
• no PATH modification required when used with OMZ
• Added bonus: Support install without sudo permissions? #51 is kind of unofficially addressed by this (assuming one uses OMZ)

Future Work

• Pre-filter using $BUFFER when hitting Alt+G to get something similar to navi query
• Update navi widget zsh to use navi.plugin.zsh

Let me know what you think. I'm working on a few cheatsheets, and will open PRs for those as they become ready.

Cheers,
Alex

@alxbl, I've created a PR with more changes: #103
Could you check that, please?
(I don't know how to add commits to this PR, given that I don't have write access to your fork 😅)

[alxbl]

Your changes looks good to me, if you'd like, I can merge them into my PR, or you can merge your PR after this one? I'll push the changes you requested.

[denisidoro]

I'd rather you merge my changes into your PR so that master will always stay up to date

[alxbl]

I've merged all of your changes into the branch. The last thing I'd like to discuss before merging is the OMZ upgrade path:

I think it would make more sense as cd "$ZSH_CONFIG/plugins/navi" && git pull considering that sudo make update will implicitly call make install, which results in symlinks in /usr/bin and partly defeats the point of having it as a plugin. Let me know what you think.

Made the fix from the discussion in #103. Should be all set if you want to take a last look before merging.

Cheers!
