Misc improvements

[bosr]

Hi,

Here are several changes

Misc improvements

Please be indulgent 😄, I'm a Vimscript newbie!

• filename change (fzy.vim)
• some refactoring / moving around of the functions (the reason why is in the notes section below)
• no bind keys by default
• add some API functions: quite a big name for just 2 functions 😂, namely fzy#get_status_string() and fzy#get_view_string(). This is for playing nice with plugins like lightline.
• add some limited ability to filter only buffer names (using the config below): it is limited because despite my efforts, I could not switch transparently between filtering buffers and filtering files. You first have to toggle a switch using <c-t> and then re-call the plugin using <c-p>. Please note that the plugins opens for buffers first. You have to toggle and re-call the plugin to filter for files. Clearly not ideal.

Config

My init.vim config for this plugin is:

nnoremap <silent> <C-p> :FuzzyOpen<cr>
let g:fuzzy_bindkeys = 1 " activate default bindkeys
let g:fuzzy_contentsearch_engine = 'ag'

Usage

<C-P> opens the plugin in buffers view
<C-T> to toggle to buffers+files view (this also kills, as <esc> does, but this is unfortunate)
<C-P> opens the plugin in buffers+files view
<C-T> to toggle back to buffers view

Notes

0. Some other contributors did some work, but honestly, I did not take the time to present their work here. Their commits are included in this PR, of course.

1. I moved around the functions because they made more sense to me. Here is my vim window with the code now (thanks to folding). I hope it is self-explanatory

2. Here is a terminal recording

Thanks in advance for your comments and ideas. Best regards

The filename change from neovim-fuzzy to fzy is probably bad practice for a PR. This should also have been broken down into more than one PR.
