In my last post i went over my history of editors and the good, the bad and the ugly about finally switching to vim, now its time to talk more about dem configs boi. My configs are a heavily modified version from Optixal’s Neovim Init.vim, i have replaced some of the plugs and added my own bindings and auto completion plugins.

Plugin Management

for plugins i left vim-plug as it is because well its great, gets the job done and doesn’t really interfere in any way, yes i do use a lot of plugins, however most of them i consider necessary for a great IDE experience, out of the box most of these functions are missing or hidden, i have added a comment for each plugin explaining what it does.

" ================= looks and GUI stuff ================== "

superior auto completion

the original Optical configs used deoplete for completion which is kinda heavy and slow (this laptop is running an 10 APU) for this machine, i tried coc which was good and super responsive but also still heavy especially with python files (jedi) i had many other options to pick from but i choose ncm2 because its fully written in vim script and was meant for Nvim so its a native environment for it, and it works pretty good so far the pop-up comes up pretty fast and the snippets work as intended. the good thing is i didn’t really need to do a very extensive setup because well this works by default i had to modify is the mapping and other simple stuff which i could’ve used another plugin for.#### Visual changes:

just as usual it has to be material ocean themed, and vim being a popular editor its already there and no need to reinvent the wheel, kaicataldo’s themes include it and you can easily set it up, other visual changes include a modified air line and a minimal NERDTree.

let g:material_style='oceanic'
set background=dark
colorscheme vim-material
let g:airline_theme='material'
highlight Pmenu guibg=white guifg=black gui=bold
highlight Comment gui=bold
highlight Normal gui=none
highlight NonText guibg=none
autocmd ColorScheme * highlight VertSplit cterm=NONE ctermfg=Green ctermbg=NONE

nifty tricks

these are Vim built in options that are not set up by default or are set to not so good defaults, i found most of these while trying to do a specific task, i used to use mswin behavior (makes Nvim behave more like a regular text editor) but now i don’t think i need it anymore, still haven’t mastered the moved as i did with good ol’ plasma.

set lazyredraw                                          " faster scrolling

NERDTree

these configs are the best, i kanged the icons from some repo which i can’t remember, it includes minimal ui (hides the top help text and other stuff), and ignores .git and Jekyll build files by default. It also quites when you open a file so you can immediately focus on the file

let NERDTreeShowHidden=1
let NERDTreeShowLineNumbers=0
let g:NERDTreeDirArrowExpandable = ''
let g:NERDTreeDirArrowCollapsible = ''
let NERDTreeQuitOnOpen = 1
let NERDTreeMinimalUI = 1
let NERDTreeDirArrows = 1
let g:NERDTreeIgnore = [
\ '\.vim$',
\ '\~$',
\ '.git',
\ '_site',
\]

Airline

airline is a fantastic status bar that shows important information like the language, encoding and current mode you’re in. my airline configs are pretty simple as well, the only big difference compared to the defaults is the added current line and percentage of the file at the right of the bar, also spell check

" Airline
let g:airline_powerline_fonts = 0
let g:airline#themes#clean#palette = 1
call airline#parts#define_raw('linenr', '%l')
call airline#parts#define_accent('linenr', 'bold')
let g:airline_section_z = airline#section#create(['%3p%%  ',
\ g:airline_symbols.linenr .' ', 'linenr', ':%c '])
let g:airline_section_warning = ''
let g:airline#extensions#tabline#enabled = 1
let g:airline#extensions#tabline#fnamemod = ':t'        " show only file name on tabs

Other great features

• auto line indentation
• display tags via tag bar
• FZF integration
• Grammer checking via Grammerous
• Snippets via Ultisnips
• startify when no buffer is open
• open images via feh

Key Mappings

The default key maps are ok but they’re missing some essential things like block selection without going back to visual mode, fast split switching and split rotation, so i made my own bindings for all these, some are from nvim help and others are scattered from the web.
i also fixed the annoying block selection will copy the selected text to the clipboard by using the void register for delete operations, this way deleting a visual block will just delete it without adding it to the clipboard.

" use a different buffer for dd
nnoremap d "_d
vnoremap d "_d

" emulate windows copy, cut behavior
noremap <LeftRelease> "+y<LeftRelease>
noremap <C-c> "+y<CR>
noremap <C-x> "+d<CR>

" switch between splits using ctrl + {h,j,k,l}

nnoremap <C-l> <C-w>l

" select text via ctrl+shift+arrows in insert mode
inoremap <C-S-left> <esc>vb
inoremap <C-S-right> <esc>ve

Other shortcuts

• F3 for nerdtree
• f4 for tagbar
• f5 to rotate splits
• maybe more

and thats all from me, these settings do almost everything i need from an IDE and keep me focused on the actual writing/coding part, and finally you can checkout the file configuration file in my dotfiles repo.
