How to Quickly Append Semicolons to Multiple Lines in Vim

When editing a short JavaScript snippet in Vim, you may need to add a trailing semicolon to every line. Manually typing a semicolon at the end of each line is tedious, so this article presents four Vim‑based methods to automate the task.

Method 1: Use the dot (.) repeat command

Press $ to move the cursor to the end of the first line, then type a;<Esc> to append a semicolon.

Press j to move to the next line and repeat the previous step with $a;<Esc> .

Repeat step 2 for each subsequent line.

The . command repeats the last change, so after the first line you can use j$. to add a semicolon to the following lines, dramatically reducing keystrokes.

Method 2: Column visual block mode

Enter block‑visual mode with <Ctrl+v> (or <Ctrl+q> in MacVim/GVim), then move down two lines with jj and to the end of the lines with $ .

Press A; to enter insert mode and append a semicolon to all selected lines.

Press <Esc> to return to normal mode, completing the insertion.

This technique leverages block selection so the inserted text is applied simultaneously to every selected line.

Method 3: Use an Ex command

Determine the line range (e.g., lines x to y) and execute: :x,ynormal A; The normal Ex command runs normal‑mode keys on each line in the range, appending a semicolon at the end. Ex commands can also be combined with pattern matching, e.g., :g/pattern/normal A; to affect only lines matching a pattern.

Method 4: Record and replay a macro

On the first line, start recording with qa , then type A;<Esc> and stop recording with q .

Move to the second line with j and replay the macro with @a .

Move to the third line with j and replay the last macro with @@ .

Macros capture a sequence of keystrokes, allowing you to apply the same edit to multiple lines with a single command.

These four approaches—dot repeat, column visual block, Ex command, and macro—provide flexible ways to add semicolons efficiently in Vim, minimizing repetitive typing and improving workflow.
