# My neovim workflow

![nvim-000](https://raw.githubusercontent.com/haunt98/posts-images/main/nvim-000.jxl)

All configs are in [my dotfiles](https://github.com/haunt98/dotfiles).

Search multiple words:

```vim
:/\vword1|word2|word3
```

Replace word:

```vim
:%s/word1/word2/g
```

Delete all lines contain word:

```vim
:g/word/d
```

Jump basic:

- `gg`: first line
- `G`: last line
- `0`: first character of line
- `$`: last character of line
- `w`, `b`: word forward/backward
- `e`, `ge`: end of word current/before
- `W`, `B`: WORD (word with special char) forward/backward
- `E`, `gE`: end of WORD current/before
- `f{char}`, `F{char}`: find forward/backward character

Jump advance:

- `CTRL-O`, `CTRL-I`: cursor position backward/forward
- `(`, `)`: sentence backward/forward
- `{`, `}`: paragraph backward/forward
- `H`: top of screen
- `M`: middle of screen
- `L`: bottom of screen
- `CTRL-]`, `CTRL-T`: jump to tag/jump back from tag
  - Support jump to Go definition with [fatih/vim-go](https://github.com/fatih/vim-go).

Use both `\` and `;` as leader key:

```lua
vim.keymap.set("n", ";", "<Leader>", { remap = true })
vim.keymap.set("n", "'", "<Leader>", { remap = true })
```

Misc keymap:

```lua
vim.keymap.set("n", "n", "nzz")
vim.keymap.set("n", "N", "Nzz")
vim.keymap.set("n", "q", ":q<CR>")
```

- `<Space>` prefix: prefer lsp keymap, for coding of course :D
