Vim reference

What is Vim?

This a straight copy of Vim notes I keep on my computer. The notes were created and are maintained for my own reference and are idiosyncratic to my needs.

Vim is a popular and powerful text editor written for efficient, mouseless writing, editing, and manipulation of text, e.g. prose and code.

Vim differs from most text editors in that there are different modes for writing (e.g. insert mode) and editing (e.g. normal mode)1. A normal session involves frequent switching between insert and normal modes depending on the task, e.g. write text in insert mode, switch to normal mode to delete the current sentence using the quick ‘das’ key sequence, then switch back to insert mode to continue typing.

Variants of Vim

There are graphical versions of Vim and terminal versions of Vim, and many integrated developer environments (IDEs) or analysis environments even have Vim-modes for code editing. Examples:

• Vim (vim): Traditional, terminal-based Vim. macOS comes with a system version, but it isn’t kept up to date. A current version, installed through Homebrew, is recommended.
• GVim: Graphical Vim.
• MacVim (mvim): macOS graphical Vim. Comes with an executable script mvim2 that can be used to invoke MacVim from the command line.
• NeoVim (nvim): Modern fork of Vim with improved architecture. Installed using Homebrew. See ‘Differences betwen Vim and Neovim’ for further information.

Other Vim-based editors I have used:

• VimR: NeoVim GUI for macOS. The program is still in alpha development, but it has many promising features including Markdown preview and a file browser.

Programs with Vim-mode editing:

• RStudio

Differences between Vim and NeoVim

• Location of temporary swap files (e.g. .swp files): in Vim they’re located in the same directory of the edited file; in NeoVim, they’re located in ~/.local/share/nvim/swap.

Launching Vim via the terminal

Note: Substitute your preferred Vim, e.g. gvim, vim, or nvim, for mvim in the table below. See ‘Variants of Vim’ below for a description of the variants.

Cmd Description
mvim Open a single file
mvim file1 file2 ... Open multiple files. Buffers are created for each file, but only the first file file1 is displayed in the window. To switch to another opened file, see buffers.
mvim -p file1 file2 ... Open multiple files. Each file is opened in a seperate tab. Only applicable to graphical Vim (e.g. MacVim)
mvim -d file1 file2 Open two files in vimdiff mode: both files are opened in a seperate vertical split, the differences between the files are highlighted, and the files are coupled such that scrolling in one file also scrolls in the other file (i.e. the current lines in both files are the same).

Vim Modes

Basic Modes

Vim has six basic modes.

• Normal (n): Command mode. Mode in which you can enter all the regular commands. Cursor appears as a square. You can end Insert Mode and go to Normal Mode by by pressing <esc> or <Ctrl>-[.
• Insert (i): Typing mode. The text you type is insert in the file (current buffer). If in Normal Mode, Insert Mode can be accessed by pressing a or i.
• Visual (v): Similar to Insert Mode, but you can select the text over which the commands apply using movement commands.
• Command-line mode (c): Type in and execute a single expression from the bottom of the main Vim window. Command-line mode is accessed from Normal or Visual mode by pressing :. Enter the command and then execute it by hitting <Enter>. The mode will return to Normal mode after completion of the command.
• Ex mode (e): Type in and execute multiple expressions. Like Command-line mode, except you remain remain in Ex mode after entering a command. Infrequently used mode.

Vim has six additional modes. These are variants of the basic modes.

• Operator-pending (o): Similar to Normal mode. You’ve started an Operator command, but are still waiting for a {motion} to specify the text that the operator will work on.
• Replace (r): Like Insert mode, but you overwrite rather than add text. Replace mode is accessed by entering R in Normal mode.

⇧ Back to TOC

Repeating commands

Most commands can be optionally prefaced by an integer N to repeat the command N times. For example, 2dw for delete two words.

The column N? shows if this is possible and makes sense, i.e. exhibits the expected behavior.

⇧ Back to TOC

Table Key

The following symbols have special meaning in the Cmd column for all document tables.

• N: Integer. Reserved for repeating part or whole of a command. Whole commands can be repeated (see repeating commands below) or it might show up in the middle of command as part of, for example, a movement (see reformat a line or paragraph).
• n: Integer. General use.
• x: Single character
• s: String
• C: Command
• []: Optional component

Each command (under Description) has been given a usefulness score that appears at the end of each Description entry.

• [3]: Very useful. Used every session.
• [2]: Useful. Used often, but perhaps not every session.
• [1]: Worth knowing. Used, but infrequently.

Exiting Vim

Start with the most important question first: how do I exit Vim?

These commands must be entered in normal mode. If you see a blinking, square-block cursor (“ █ ”) , you’re in normal mode. If you see a blinking line cursor (“ │ ”), you’re in insert mode. To go from insert mode to normal mode, hit the escape (Esc) key.

To quit a buffer instead of a window, see Sec. ‘Closing buffers’. See Sec. ‘Buffers’ for the difference between buffers and windows. Note that tabs count as different windows.

Cmd N? Description
:quit or :q N Quit the current window (not just the current buffer). If the current window is the only window, exit Vim. Quit fails if an opened buffer has unsaved changes or if there is an unnamed buffer (a new buffer that isn’t associated with a file). If the current window is the only open window, close the window and exit Vim. [3]
:quit! or :q! N Quit the current window (like :quit), but quit even if there are buffers with unsaved changes. [3]
:qall or :qa N Quit all windows, not just the current window and exit Vim. Exiting Vim fails if there are buffers with unsaved changes. [2]
:qall! or :qa! N Quit all windows and exit Vim. Always exit. Any unsaved changes or unnamed buffers are discarded. [3]
:wq N Write to (save) the current buffer and quit the current window. Quit fails if the current buffer is unnamed, or if there are other buffers with unsaved changes. [3]
:wq! N Write to (save) the current buffer, even if it’s marked read-only, and quit the current window. Quit fails there are unnamed buffers with unsaved changes. If there are other buffers with unsaved changes, discard them.
:wqall or :wqa N Write to (save) all named buffers, quit all windows, and exit Vim. [3]
:wqall or :wqa N Write to (save) all named buffers, quit all windows, and exit Vim. [3]

Do not change the extent of the selected text. [1] ⇧ Back to TOC Delete (cut) text General form Deletion commands follow the general Vim pattern: [command] + [movement]. For example: • dw: Delete to end of the word ([delete] + [move to end of word]) • d$: Delete to end of the line ([delete] + [move to end of line])

Using this pattern, we can improvise any number of deletion commands. For example:

• d5j: Delete the next five lines, including the current line ([delete] + [move 5 lines down])

There are special deletion commands: di for delete inside and da for delete all. They have the general form [da/di] + [boundary]. The boundary is a character that characterizes the extent of the environment of what we want to delete: ( or b for a matching pair of parentheses, [ for a matching pair of square brackets, s for a sentence, w for a word, and so forth.

• di commands delete the text inside the boundary
• da commands delete the text inside the boundary and the boundary indicators (e.g. delete the text and the brackets)

Delete to register

Deleted (or yanked) text automatically goes into the unnamed (default) register ". This is what Vim uses when you paste text using p.

See: ⇧ Back to TOC Spell checking and dictionaries Vim uses three dictionaries when checking for misspelled words: the main, immutable dictionary for the current language and region (for me, the spelllang is en_us; this can be changed if needed); a spellfile, a supplementary list of words that that Vim should treat as correctly spelled even though they aren’t recognized by the main dictionary; and a temporary spellfile for the current session. A spellfile is just a list of words. They can be directly edited, either by command (e.g. zG to add a word to the spellfile) or by manually editing the file. The default spellfile loaded by Vim for my language and encoding is ~/vim/spell/en.utf-8.add (for Vim) and ~/.config/nvim/spell/en.utf-8.add (for NeoVim). You can create new spellfiles. This is very useful when working on files or projects that have a lot of specific words or acronyms that you don’t want to add to a common dictionary. For example, in my Deorcost D&D campaign, I have a lot of character and monster names that are aren’t English words but that I don’t want to mark as incorrectly spelled. I created a new spellfile called deorcost.utf-8.add. All spellfiles must end with <file-encoding>.add, e.g. *.utf-8.add. To set the location of the spellfile (if the file doesn’t exist a new one will be created): :set spellfile=~/path/to/spellfile/mydictname.utf-8.add The third source for valid words is the internal word list. The internal word list is a temporary dictionary that only exists for the current buffers. The dictionary vanishes once Vim is exited. Words are added to the internal word list using the command zG. Vim, by default, marks words it finds misspelled with an underline. Cmd N? Description :set spell No Turn on spell checking. [3] :set nospell No Turn off spell checking [3] ]s Yes Move to the next mispelled word [3] ]S Yes Move to the next mispelled word. Only stop at bad words, not rare words (in the default English dictionary, only the word “vim” is marked as rare) or words that are valid in another region (same language but different region, e.g. American English versus UK English). [1] [s Yes Move to the previous mispelled word [3] [S Yes Move to the previous mispelled word. Only stop at bad words, not rare words or words from another region. z= No For the misspelled word under the cursor, suggest correct spellings [3] zg No Add the word under the cursor to the current spellfile as a good word [3] zw No Remove the word under the cursor from the dictionary as a good word. If the word was previously added to the spellfile, it is commented out. [2] zG No Add the word under the cursor to a the internal word list as a good word. This will prevent the word from being marked as incorrect for the buffers. As soon as Vim is exited, the internal word list is discarded.

Many files may be loaded into memory (many buffers) while just one is displayed (single window). Buffers allow us to quickly jump between different files. ⇧ Back to TOC Showing buffers Buffers are shown using the :ls command. The output shows: • Column 1: The buffer. This number indicates how the buffer should be addressed. E.g. :b 2 opens buffer 2 in the current session. • Column 2: Which buffer is active (%a), which buffers are hidden (h), the previously accessed buffer (#h) for the current window. • Column 3: If a file has been edited but not yet saved, there will be a + in this column. Otherwise it will be empty. • Column 4: The file and filepath relative to the current working directory. If the file content hasn’t been written to disk, it will be listed as "[No Name]". Cmd N? Description :ls N List all buffers Example output: :ls 1 h "vim.md" line 155 2 h + "git.md" line 1 3 h "[No Name]" line 1 3 #h "root_analysis.py" line 22 4 %a "root_analysis.sql" line 1 A buffer can only be in the background if it hasn’t been modified, but the restriction can be removed by the :set hidden command. This is set in my vimrc file so that I don’t have enter it each time. Troubleshooting: Long file paths in :ls The listed file paths in :ls are relative to the current working directory (:pwd), which is set by the first loaded file. If buffers don’t share the same working directory, hidden files with different working directories will use their full file path relative to the user home (~). This can give unfortunately long paths in the :ls command that wrap to the next line. To fix the issue for the currently active buffer, use a working directory that is common to other buffers using the :cd <newpath> command. <newpath> can be relative, e.g. cd .. works. Unfortunately this must be done per buffer. ⇧ Back to TOC Switching buffers Switching buffers is easiest using :b <fname> with tab completion. The tab completion works on file names and paths. For example, if one of my buffers corresponds to file ~/git-projects/grav/pages/04.deorcost/episode-26/item.md, I can type :b 26<tab> (the 26 is from episode-26) and it will expand to the full file path. This is easier than remembering which buffer number corresponds to which file. Buffer numbers associated with each file can’t be reassigned and may change when re-opening a session. Cmd N? Description :buffer n No Switch to buffer n [3] :b n No Alternative to :buffer n. There does not need to be a space between :b and n. Both :b 1 and :b1 are equivalent. [3] :b <fname> No Swith to buffer with filename <fname>. The filename accepts tab-completion if :set wildmenu has been enabled (a typical default in one’s .vimrc or init.vim). Auto-completion works on any part of the filename. [3] <Ctrl>-6 No Switch to the last used buffer. Easy way to switch between buffers.

Registers are accessed, for both getting and putting content, using the double quote " character. To see all registers and their contents use :reg or :registers. ⇧ Back to TOC Register list table Register Content 0 - 9 Yanked (copied) text registers. Vim automatically populates the numbered registers, 0 - 9, with yanked text. Deleted (cut) text does not populate these registers. The latest yank goes to register 0; the second to last goes to register 1; and so forth. a - z Named registers. Deleted or yanked text can be explicitly saved to any one of these named registers for later recall. They won’t be explicitly overwritten. 0 Last yanked text register. For additional information, see Registers 0 - 9 above. " Last deleted or yanked text register (on macOS systems).

See the register list table table above for how to access previously yanked text (e.g. 2, 3 copies ago) • Yank or delete to a specific register using "<regname><cmd> before a delete or yank command <cmd>, e.g. ("kY, yank current line to register k; "kD delete to end of line and save contents to register k) ⇧ Back to TOC Pasting from a register You paste from a register in a similar way to cutting or copying to a register: "<regname><pastecmd>. The paste command is either p for paste after, or P for paste before. Examples: "kP paste contents of register k before the cursor. ⇧ Back to TOC Command examples Any yank, delete, or paste command can be used after specifying the register.

The steps: 1. Set scrollbind in window 1: :set scrollbind (equiv. :set scb) 2. Move to the next window using <Ctrl>-w <Ctrl>-w 3. Set scrollbind in window 2: :set scrollbind (equiv. :set scb) 4. And so forth, depending on how many windows you’d like bound together ⇧ Back to TOC Change a window’s width and height These commands do not effect the size of the main (terminal or program) window, and thus don’t work if only a single window is open. You can only steal or add space to neighboring windows in a multi-window environment. The equalize window size command, i.e. <Ctrl>-w=, is probably the most useful command in the table below. Cmd N? Description <Ctrl>-w= No Equalize the width and height of all windows n <Ctrl>-w + No Increase the windows height by n lines n <Ctrl>-w - No Decrease the window height by n lines n <Ctrl>-w _ No Set window height at n n <Ctrl>-w | No Set window width at n ⇧ Back to TOC Tabs Create new tabs and move between them Cmd N?

Description @@ Yes Repeat the last macro ⇧ Back to TOC Sessions It’s inconvenient to re-open the same buffers and window configuration for a project every time Vim is opened. Fortunately your entire configuration, i.e. your session, can be saved using the :mksession command. That session can then be loaded within an open Vim window (using :source <sname.ses>) or at Vim launch using mvim -S <sname.ses>. Cmd N? Description :mksession N Save a Vim session to file Session.ses [2] :mks N Short form of :mksession (above) [2] :mksession {sname.ses} N Save a Vim session to disk to filename <sname.ses>.

Description :pwd No Print the current directory name [1] cd {path} No Change the current directory to {path}. This applies to all open buffers. [1] :lcd {path} No Set the current directory for the current window only. The current directory for other windows is not changed.

Description <Ctrl>-a No Increment integer under cursor [1] <Ctrl>-x No Decrement integer under cursor [1] <Ctrl>-[ No Escape [1] g <Ctrl-g> No [Visual] Count the number of words in the visual selection Syntax highlighting Assuming a normally configured ~/.vimrc with syntax enable and filetype plugin on and the correct syntax plugins installed, a displayed file should have syntax highlighting. Sometimes, often with large files, highlighting can break. A few problems and solutions are found below. ⇧ Back to TOC Problem: No syntax highlighting Check if a syntax file3 has been loaded. Run, :setlocal syntax? If the command returns with no associated file (i.e. the command returns syntax= with nothing after the equals sign) or an unexpected filetype, you can manually associate a new or different syntax file with the document. For markdown files, because I have the vim-pandoc and vim-pandoc-syntax, plugins the syntax filetype should be pandoc, i.e. :setlocal syntax=pandoc Setting syntax=markdown may also work. ⇧ Back to TOC Problem: Syntax highlighting is broken or malformed The first thing to check is that your code or text is correct. Usually syntax highlighting are broken because of a misplaced closing tag or bracket or character. If you’re convinced that there’s nothing wrong with the content of your document, there are a few commands you can run to try and fix highlighting. • Adjust the minimum number of lines Vim goes back to find the start of the environment (e.g. an opening tag or bracket) for the current syntax highlight syntax sync minlines=20 Larger values will improve accuracy, but slow down highlighting • Re-do highlighting of the document, starting from the start :syntax sync fromstart • Increase the amount of time Vim has to draw a screen of text. If this limit is hit before Vim is finished calculating the correct syntax highlighting for the current screen, syntax highlighting will fail. set redrawtime=10000 ⇧ Back to TOC Plugins Useful details and commands about installed plugins.
