The "/ register stores the last search, and the ": register stores the last command. I use `":p` to paste commands into buffers all the time

"% stores the filename but I prefer to do `let @+=expand("%:p")` to copy that to clipboard

1. [[ and ]] in the `:terminal` jumps between invocations of your shell
2. :verb :map <mapping> tells you where in your config a mapping was set. :verb :set <option> tells you where an option was set
3. Don't provide a pattern to :s style cmds (:s//foo) and the most recently used pattern is applied

`[[` is insanely cool but sadly I don't think works with powershell

Ran into a hard wall trying to improve a plugin, because plugin panels can only have buttons and no other interactives

I think "is it fun for you to tinker with this config" is a big differentiator on this. Like I love tinkering with neovim but hate tinkering with OSes

Almost 1500 people have purchased copies of *Logic for Programmers*! Has anybody had any experiences trying to apply the ideas in practice? Want to know if the book is doing its job!

IE, I'm willing to invest the time and effort into configuring Neovim and reap the benefits from that. But I'm unwilling to embrace the complexity of linux distros. My 1% is different from Julia's 1%, and ours is different from your 1%.

(Maybe for some people the ratio is different, not 99%/1%)

I always thought the choice was about mindsets: 99% of people were best with simple, usable, software, 1% were best with highly tweakable, customizable software.

But I assumed @b0rk.jvns.ca was in the 1%, but she also is switching to Helix!

More likely it's 99% of contexts, not 99% of people.

Compare installing plugins for Neovim and VScode. Setting up a plugin in Neovim is painful, though it'll be better in the next release. Adding a plugin to VScode is easy. It's easier because VScode is so much less customizable, so can make more assumptions in the code.

Vim is incredibly, insanely customizable. You can, if you really want to, make your keybindings depend on the colorscheme and day of the week. This customizability comes at the cost of complexity. I am convinced that for 99% of developers, the tradeoff is not worth it.

I find this article by @b0rk.jvns.ca really fascinating: "Notes on switching to Helix from Vim"

I see Julia as a "tinkerer" who's really good at customizing her environments, *and also* she very much enjoys how she doesn't have to configure Helix.

Some thoughts:

you can define custom insert mode mappings, too!

map('i', ';r', '+') -- insert the clipboard
map('i', ';D', [[=strftime('%D')]]) -- insert the current date in US-format

Peter Lyons @peterlyons.com · 1d

You can use abbreviations in insert mode for pure beauty like I type qv<space> (mnemonic quote variable) in insert mode and get "${}" with cursor between the braces.

Hillelogram @hillelwayne.com · 1d

While you should ALMOST ALWAYS use `noremap`, regular recursive `map` is great for integrating with plugins. Like making `\`` surround a word with backticks, by mapping to the vim-surround (or nvim-surround) keystrokes

`n.` is good but for trickier things I prefer `%s/

/replacement/cg`, which copies the word under the cursor into a search/replace

In general I don't use `.` very much, despite its power

bsky.app/profile/woma...

Candy Corn Woman 🌽 @womancorn.bsky.social · 1d

n. Is the precursor to refactoring.

Suppose you want to rename a variable: /varname will put you at the start of the next instance. ce replaces the variable with whatever you type.

n repeats the last search and . repeats the last whole edit motion, so you can repeat n. to change the next one.

No tip this time, just emphasizing this one. Discovering text objects is what made vim go from "that thing everybody keeps telling me is amazing" to "amazing"

bsky.app/profile/nick...

Nick Canzoneri @nickcanzoneri.com · 1d

Text objects! Perform an action inside/around parens/bracket/tag

ie to yank everything inside an html tag where the cursor is: yit

To delete everything in parens (including the parens): da(

Morning nerds

I have :b# mapped to `\w`. I like having TWO leader keys: I use for general stuff and `\` for telescope + saving + a few others

bsky.app/profile/oppi...

akshay oppiliappan @oppi.li · 1d

ctrl+^ to switch to the most recently used buffer! similar to :b# on command mode.

i use it all to time to switch back and forth between docs and work.

ctrl-o and ctrl-i to jump back and forth betwwen items in the jumplist.

`gf` to follow a path under the cursor; nice with langs that import paths

In insert mode you can press `ctrl-R {register}` to paste that register. In command mode `ctrl-R ctrl-W` will put in the command line the word under your cursor. There are a few other commands, too, it's quite useful!

bsky.app/profile/josh...

Josh Finnis @joshfinnis.bsky.social · 2d

"Full line completion" `i_<C-X><C-L>` is very useful to repeat lines like console.logs. All my notes are in Nvim and I find ad-hoc uses for this constantly.

I map all completions to <tab> (so `i_<tab>l`) in insert mode because I've never wanted to type a tab on purpose.

`ctrl-w _` makes the window take all the vertical space on the screen, `ctrl-w |` makes it take all horizontal. Good for temporarily focusing one window

Also TIL about `z{count}`, which sets the window to {count} high

bsky.app/profile/josh...

Josh Finnis @joshfinnis.bsky.social · 2d

Splits resize when window size changes. Useful because I often have multiple splits alongside tmux panes (logs, test runner, etc) and resize those if they need more focus:

vim.api.nvim_create_autocmd('VimResized', {
command = 'wincmd =',
})

Is the § on your keyboard?

Hillelogram @hillelwayne.com · 1d

I think without that, you populate the argument list instead? Forget the specifics.

Regardless, you can run a command on every arglist, quickfixlist, window, or buffer with `argdo/cdo/windo/bufdo". GREAT for mass interactive find/replace

bsky.app/profile/norm...

Normal Mode @normalmo.de · 2d

Vim’s -q argument allows you to prepopulate the quickfix list directly on startup.

e.g. using ripgrep via bash’s process substitution:

vim -q <(rg --vimgrep needle)

Capital marks (set with `mA`, `mB`, etc) are global between files. I have `tmp.md` always set to the T mark, and regularly use marks A and B for when I need to come back to some random file multiple times in a session.

You can also use these with macros!

bsky.app/profile/norm...

Normal Mode @normalmo.de · 2d

Vim has a built in MRU list.

Use :oldfiles to view it, and e.g. :e #<5 to open the fifth entry in the list.

One of my favorite tricks is

`:10,29co .`

To copy lines 10-29 to under the cursor. Makes it really easy to duplicate tests for modification or move stuff around (with `move` instead of `co`)

bsky.app/profile/buff...

panic! at the alamo @buffaloshuffle.bsky.social · 2d

Idk if it's much of a script but setting typewriter mode (scrolloff = 999) and j/k to gj and gk to move by row are my like two favorite settings lol

1 4

Hillelogram @hillelwayne.com · 2d

Protip: instead of `noremap j gj`, try `noremap <expr> j v:count == 0 ? 'gj' : 'j'`. That way you can still use `10j` and `10k` to jump multiple lines like you'd expect
