Add fish-style directory paths

[xvilo]

This will add fish-style directory paths when one has shrink_path installed.

Closes #52

Dumb question: how do you use shrink_path command in the Theme? I tried copying your theme as a custom theme (removing the IF to force shrink to execute), but I keep getting command not found shrink_path when opening my terminal.

I was a bit confused about this merge request...... since It's been long that I don't really remember.

But to answer your question directly, I've made my own ( hard-coded ) agnoster-theme that sets the path to be fish like. IE instead of ~/usr/projects/personal/super-proyect it will show you ~/u/p/p/super-proyect trimming the initial part.

The code that does that is the following:

  local trim_path=$(print -P ' %~ ' | sed -E -e "s#([^a-z]*[a-z])[^/]*/#\1/#g")
  prompt_segment blue black $trim_path

You can use my forked version here: https://github.com/aemonge/agnoster-zsh-theme

Or if @gdlm91 is able (cause I can't) to merge it to utilize the shrink_path would be Awesome !

[xvilo]

can we still merge this maybe?

[aemonge]

It would be my pleasure;) Any thoughts on this @agnoster ?

Does this PR supersede #52? If so, you should put "Closes #52" in the PR summary, so the other PR will be auto-closed if this one gets merged.

@apjanke done

[apjanke]

Thanks!

@aemonge / @agnoster any update?

[aemonge]

Not from my part. But this I can spend some time during January to work on enabling such feature with a configuration variable :)

[apjanke]

If y'all are interested, I added this to my AgnosterJ fork.

I've made a push to enable the trim path by export AGNOSTER_THEME_TRIM=1; in your ~/.zshr file.

@apjanke what does your pull-request do? Did you implement this by a use of a plugin ?

My thingy is a fork of Agnoster, not a Zsh plugin. In my version, no plugin is needed; it just makes use of zsh's native prompt support.
