Vim-Plug Quick Setup

I want you to try this .vimrc setup.

I have had my own .vimrc for years. I recently came across fisa-vim-config and ended up dropping my extensive .vimrc, adopting the one above and adding a few tweaks to make it friendly to me. I was actually looking for more ALE-fixers when I found this gem.

It is simple, self installing and very powerful due to the vim Plugins that are installed and loaded.

Here are the steps I want you to try… trust me here.

• mv ~/.vimrc MyOld.vimrc # or whatever your favorite backup scheme is I actually name mine with a date eg 20190315.vimrc
• mv ~/.vim MyOld.vim
• download fisa-vim-config and replace your old ~/.vimrc
• run vim on any file you want

Much credit to the author of fisa-vim-config: Juan Pedro Fisanotti!

There is more to do here but if you do those steps you will see lots of new Vim Plugins get loaded automagically.

You can actually remove the ~/.vim (it has root owned .git subdirectories so you will have to force remove the directory).
Run vim again and your ~/.vim directoy will automagically get built out again.

Now tweak your shinny new ~/.vimrc file. First I want vim to remember where I left off in a file and put the cursor there when I return to that file. Add this to the end of ~/.vimrc.

" ======= remember cursor position and viminfo settings  ========
" Tell vim to remember certain things when we exit using set viminfo=
"  '10  :  marks will be remembered for up to 10 previously edited files
"  \"100 :  will save up to 100 lines for each register
"  :20  :  up to 20 lines of command-line history will be remembered
"  %    :  saves and restores the buffer list
"  n... :  where to save the viminfo files
set viminfo='10,\"100,:20,%,n~/.vim/dirs/viminfo
" now function that restores the cursor position and its autocmd so that it gets triggered:
function! ResCur()
if line("'\"") <= line("$")
  normal! g`"
  return 1
  endif
endfunction
augroup resCur
  autocmd!
  autocmd BufWinEnter * call ResCur()
augroup END
" ======= EOB remember settings ================

Note: the file viminfo line is supplanting the viminfo line already in fisa-vim-config vimrc.

You good folks probably know that I am a huge fan of vim ale so lets add that plugin… this so easy! #end() You have to add this between the start [call plug#begin('~/.vim/plugged')] and the end [call plug#end()] of the Vim plugins section.

" ALE for vim
Plug 'https://github.com/w0rp/ale.git'

I didn’t care for the color schemes and some other annoying or problematic Plugs so…

• commented out all the references to it using .vimrc comment character which is the double quote.
• commented out the set nu to stop the line numbering.
• commented out the Plug … syntastic … line as it caused conflicts on large code files
• commented out some of the backup and swp file settings.

Then I added a few of my own tweaks:

" numbers on or off
nnoremap <Leader>nn :set nonumber<CR>
nnoremap <Leader>sn :set number<CR>
" toggle neocomplcache pop up boxes
nnoremap <Leader>nt :NeoComplCacheToggle<CR>
" ALEToggle
nnoremap <Leader>at :ALEToggle<CR>

Oh, and one more significant change. For python editing I added this ftplugin file:

mkdir ~/.vim/ftplugin

Then vim ~/.vim/ftplugin/python.vim and add:

let b:ale_linters = ['flake8']
let b:ale_fixers = [
\   'remove_trailing_lines',
\   'isort',
\   'ale#fixers#generic_python#BreakUpLongLines',
\   'yapf',
\]
" be careful with this - it can get wonky and you may have to :q! to avoid writing out errors
nnoremap <buffer> <silent> <LocalLeader>= :ALEFix<CR>

That last line allows me to run the vim <leader>= (ie = ) and automagically lots of fixes occur to my python code.

Within vim you can run :ALEInfo and get LOTS of useful information and suggestions. I loaded all the suggestions and oneof the most useful for python is ‘yapf’. I don;t remeber exatcly how I installed it but my guess is somthing like this:

sudo -H pip3 install yapf

I might have change Airline status line a bit too, but you do what you want:

" Airline ------------------------------
" apt.sh -i powerline fonts-powerline # to get what you will need here
"let g:airline_powerline_fonts = 0
let g:airline_powerline_fonts = 1
"let g:airline_theme = 'bubblegum'
"let g:airline_theme = 'base16'
let g:airline_theme = 'papercolor'
let g:airline#extensions#whitespace#enabled = 0
" to use fancy symbols for airline, uncomment the following lines and use a
" patched font (more info on the README.rst)
if !exists('g:airline_symbols')
let g:airline_symbols = {}
endif
"let g:airline_left_sep = '⮀'
"let g:airline_left_alt_sep = '⮁'
"let g:airline_right_sep = '⮂'
"let g:airline_right_alt_sep = '⮃'
"let g:airline_symbols.branch = '⭠'
"let g:airline_symbols.readonly = '⭤'
"let g:airline_symbols.linenr = '⭡'

And make sure you still have 256 colors:

" use 256 colors when possible
if (&term =~? 'mlterm\|xterm\|xterm-256\|screen-256') || has('nvim')
    let &t_Co = 256
"    colorscheme fisa
"else
"    colorscheme delek
endif

Add this line to the Tagbar section to have navigation a little less intrusive:

let g:tagbar_autoclose = 1

Oh, at this point there is one thing you may want to do and that is make a backup copy of your ~./vim/ftplug dir.

The reason is, you can still forcefully remove .vim directory and it will get rebuilt by your .vimrc BUT it won;t rebuild your.vim/ftplugin directory.

Ummm, one other item I finaly had to change. I turned neocomlcache off by default because it just got to obnoxious: If you are the same way, do this change:

let g:neocomplcache_enable_at_startup = 0

` Take time to appreciate some of the plugins:

• Airline is giving you the status lines Try :help Airline
• TagBar is another useful tool for large code files. While editing some code try :TagBar and use it to navigate through your code.

If you want to see the power you now hold in your knapsack… :map

Here is some quick fun vim… from the command line:

vim -O ~/.vimrc ~/.vim/ftplugin/python.py ./.bashrc

Then hit ‘-’, yes, just hit ‘-’. Slick!

BTW You can update all these Plugins while in vim with :PlugUdate And you can upgrade vim-plug itself with :PlugUpgrade. You can get help for any of the ALE* commands eg. :help ALEFixSuggest

Let me know if I forgot something or should make changes.

-=* Enjoy! *=-
