Navigating and manipulating text efficiently is a hallmark of Vim, the venerable text editor. While copying and pasting might seem straightforward, Vim’s modal nature offers unique approaches that can significantly speed up your workflow. Here are five quick ways to copy-paste lines in Vim, tailored for both beginners and seasoned users:
1. The Classic Yank and Put: The Workhorse Method
yy followed by p is the bread and butter of Vim copying and pasting.
How it works:
yyyanks (copies) the current line.pputs (pastes) the copied line below the cursor.Example: Place your cursor on the line you want to copy, type
yy, then move to the desired location and pressp.Pro Tip:
nyywhere n is a number, yanks n lines.
2. Visual Mode Selection: Precision Copying
How it works: Enter visual line mode with
V, then use the arrow keys orj/kto select the lines you want to copy. Pressyto yank the selection, thenpto paste.- Example: To copy lines 3 to 5, move your cursor to line 3, press
V, then2j(down two lines),y, and finallypat the desired location.
- Example: To copy lines 3 to 5, move your cursor to line 3, press
Advantage: Offers precise control over which lines to copy.
- Pro Tip: Use
oto toggle between visual line mode and visual character mode for even more granular selection.
- Pro Tip: Use
3. The Black Hole Register: Temporary Storage
How it works: Vim has a special register called the “black hole” register, denoted by
”_. Yanking into this register effectively deletes the text. To copy a line without affecting the default register, use”_yy.Example:
”_yycopies the current line without overwriting your previous yanked text.Use Case: Useful when you want to temporarily remove a line for comparison or experimentation without losing your original copy. 4. Pasting Above:
Pfor Precision PlacementHow it works:
Ppastes the yanked text above the cursor, whileppastes it below.Example: Yank a line with
yy, then move to the desired location and pressPto paste it above the cursor.Advantage: Provides more control over the paste position, especially when inserting lines in the middle of a document.
5. Repeating the Last Yank: *.` for Efficiency
How it works: After yanking text with yy or any other yank command, pressing *.` repeats the last yank command.
Example: Yank a line with yy, then move to multiple locations and press *.` to paste the same line repeatedly.
Pro Tip: Combine this with p and P for quick duplication of lines in different positions.
Beyond the Basics: Advanced Techniques
Named Registers: Vim allows you to store text in named registers (a-z) for later use. “ayy yanks into register ‘a’. To paste from register ‘a’, use “ap.
Macros: Record a sequence of commands, including yanking and pasting, with the q command. Replay the macro with @q.
Plugins: Explore plugins like ‘vim-surround’ or ‘vim-multiple-cursors’ for even more powerful text manipulation capabilities.
