suda.vim for sudo access to files

2022-12-21T09:45:34Z

I regularly need to edit system config files - take /etc/sanoid/sanoid.conf as an example… I’ll want to play with something but if I don’t start Neovim as root then I get in trouble making edits I can’t save! So suda.vim gives me :SudaWrite which let’s me write that buffer with sudo privileges even though I’m Neovim is running with my login user!

Description of my proposed vimconf 2022 talk

2022-11-12T19:39:19Z

Switching to Vim opened a whole new world to me for interacting with a computer and for getting things done. Before I adopted Vim I used GUIs for everything because I thought that’s how it had to be done… Notes in OneNote, code using a GUI editor, different notes in TiddlyWiki, slides for work in PowerPoint, slides for church using Logos, etc… Adopting Vim allowed me to disconnect a specific tool from the problem that tool is solving - because usually I just need to write text (notes, code, slides, etc.). Now, very nearly everything I do is from a text-based and git-based workflow… I put all my notes on basically anything just in my blog, which is all markdown and deployed to GH with Markata on every push (living dangerously pushing to main) - and that’s all done easily from Vim with nice syntax highlighting, fast response, integrated git-plugins, etc.. I keep project-specific task lists just in markdown files and I have Vim/tmux shortcuts to quickly add todos for any project (todo list is done with markata todoui) and I can get there fast because my Vim workflow dovetails with Tmux nicely. Also I can pull that list up right from the terminal, which I’m already in because Vim…. Vim also pushed me into the cli more - because Vim is so easily extended with cli tools and I’m already in the terminal… The builtin functionality also made things make more sense - no more right-click, find “refactor all” or “rename symbol” (for some stupid reason)… Vim find-replace is so intuitive and if I need it extended then I learned what sed was because of Vim. Moving quickly in Vim also enables me to do my job incredibly fast because I hop into several projects a day in a coaching role - if I was bound by GUIs I’d be waiting forever for startup, would lose which GUI instance was which project, etc… Being in the terminal also made Tmux a trivial choice - now I have 90 tmux sessions, all named appropriately, ready for me to jump back to and all while keeping the majority of RAM still free for Chrome. Vim as my IDE also forced me to learn way more about Python (I’m a python developer primarily), how LSP works, how to configure a development environment, etc… things I took for granted in my GUI workflows, or never knew, or worse - thought I knew but deeply misunderstood. Now that I understand them better, I can coach my peers more effectively even if they are still in a GUI-based ecosystem.

Basically, (Neo)Vim actually did change my life and I’m really thankful for it (maybe that should be the title?)

Case-insensitive search in Vim

2022-10-21T06:40:21Z

/mysearch\c will match mysearch, MYSEARCH, mYSeArCh…

Use the right lspsage, you dope!

2022-10-14T19:41:44Z

If you think glepnir/lspsaga.nvim config will work with tali5/lspsaga.nvim installed… you’re in for a rude awakening. Double check your forks folks!

See git history about one file

2022-05-19T06:43:32Z

In vim G clog % does a git clog {current file}. You get every commit that the target file is apart of (so there might be info in those commits unrelated)

Plug Snapshot!

Filepath Completion in Neovim

2022-05-17T14:03:27Z

I’ve had Plug 'hrsh7th/cmp-path' in my plugins for ever but didn’t notice until recently that I wasn’t getting any filepath completion in vim!

Fuller setup instructions below the TLDR

TL;DR

Turns out I need to not be a dope and configure nvim-cmp to actually use it…

local cmp = require'cmp'

cmp.setup({
    -- removed rest of setup - see the rest in my dotfiles
  sources = cmp.config.sources({
    { name = 'path' },  -- This needs to be here!
    })
})

My Setup

For the sake of completeness here is how I currently (May 2022) configure completion in Neovim usin nvim-cmp

Plugins #

I keep all my plugins in plugins.vim

call plug#begin(s:plug_dir)
Plug 'neovim/nvim-lspconfig'
Plug 'hrsh7th/cmp-nvim-lsp'
Plug 'hrsh7th/cmp-buffer'
Plug 'hrsh7th/cmp-path'
Plug 'hrsh7th/cmp-cmdline'
Plug 'hrsh7th/nvim-cmp'

" For ultisnips users.
<!-- " Plug 'SirVer/ultisnips' -->
<!-- " Plug 'quangnguyen30192/cmp-nvim-ultisnips' -->

call plug#end()

Vim Settings #

My vim settings are also kept in their own file, settings.vim


set completeopt=menu,menuone,noselect

nvim-cmp configuration #

I have a cmp.lua file that gets sourced in init.lua (file structure explained below) for configuring cmp.


  -- Setup nvim-cmp.
local cmp = require'cmp'

cmp.setup({
  snippet = {
    -- REQUIRED - you must specify a snippet engine
    expand = function(args)
      -- For `ultisnips` user.
      vim.fn["UltiSnips#Anon"](args.body)
    end,
  },
  window = {
      completion = cmp.config.window.bordered(),
  },
  mapping = {
    ['<Down>'] = cmp.mapping.select_next_item({ behavior = cmp.SelectBehavior.Select }),
    ['<Up>'] = cmp.mapping.select_prev_item({ behavior = cmp.SelectBehavior.Select }),
    ['<C-d>'] = cmp.mapping.scroll_docs(-4),
    ['<C-f>'] = cmp.mapping.scroll_docs(4),
    ['<C-Space>'] = cmp.mapping.complete(),
    ['<C-e>'] = cmp.mapping.close(),
    ['<Tab>'] = cmp.mapping(cmp.mapping.select_next_item(), { 'i', 's' }),
    ['<CR>'] = cmp.mapping.confirm({
      behavior = cmp.ConfirmBehavior.Replace,
      select = true,
    })
  },
  sources = cmp.config.sources({
    { name = 'nvim_lsp' },
    { name = 'ultisnips' },
    { name = 'buffer' },
    { name = 'path' },
    { name = 'tmux' },
    })
})

The sources section is what was key for this post…

Piecing it together!

My init.vim sources plugins and then settings and then finally calls init.lua. init.lua sources my cmp.lua file and BANG! auto-completion.

More sources #

hrsh7th’s wiki for nvim-cmp is here and has example configs as well as a list of sources…

Don’t forget to configure and not just install!

Vim-Spell-Check

2022-04-01T00:00:00Z

Did you know you can spell check in Vim?!

Vim Spell check

Without... #

Here is a missspelled word.

  <h3>With!</h3>
  <p>Here is a <u>missspelled</u> word.</p>

What is this magic??? #

set: spell spelllang=en_us

Custom words? #

Sometimes there’s things that are words to you but not the default spell checker…

Common example: package names!

plotly, streamlit, psutil, etc etc…

You can easily add these to your vim config by hitting zw ontop of the word!

Vim-Auto-Space

2022-03-04T00:00:00Z

I ran into an issue where I had some copy-pasta markdown tables in a docstring but the generator I used to make the table gave me tabs instead of spaces in odd places which caused black to throw a fit. Instead of manually changing all tabs to spaes, or trying some goofy :%s/<magic tab character>/<%20 maybe?>/g I learned that Vim has my back…
