Master Vim Macros: Automate Repetitive Text Editing in Seconds

Why Use Vim Macros?

When editing plain‑text files you often need to repeat the same text, generate a series of numbered lines, or prepend identical content to each line. Performing these actions manually is tedious and error‑prone, but Vim macros let you automate them with a few keystrokes.

Recording a Macro

Open a new or existing file in Vim.

Press q followed by a macro name (e.g., b) to start recording. The status line will show recording @b.

Perform the editing actions you want to repeat (insert text, move cursor, etc.).

Press q again to stop recording. The macro is now stored under the chosen name.

Running a Macro

Place the cursor where you want the macro to act, then type @ followed by the macro name to execute it once. To repeat it n times, type n@macro (e.g., 4@b runs macro b four times).

Example 1 – Generate 100 Identical Lines

Goal: create 100 lines containing the same phrase.

Create a file file1.txt.

Start recording with qz (macro name z).

Enter insert mode ( i) and type the desired text, e.g., Learning Vim Macros.

Press Esc then q to stop recording.

Now 100@z will produce 100 copies of that line instantly.

Example 2 – Generate a Number Sequence (101‑110)

Goal: produce a list of consecutive numbers.

Create file2.txt and type 101. in insert mode.

Exit insert mode with Esc, then start recording a macro qy (name y).

Copy the current line with yy, paste it below with p, then increment the number using Ctrl‑a.

Stop recording with q.

Running 8@y generates the numbers 101 through 108; adjust the count to reach 110.

Example 3 – Prepend an SQL Insert Statement to Each Line

Goal: turn raw data lines into full INSERT statements.

Open file3.txt containing the raw values.

Start a macro qd (name d).

Enter insert mode ( i) and type insert into items values(, then exit insert mode.

Use w to move to the next word and yw five times to copy the five parts of the line (value, comma, type, comma, brand).

Append ); at the end of the line with a then Esc.

Move to the next line with j and stop the macro with q.

Execute 3@d to apply the macro to the remaining three lines, instantly producing correctly formatted SQL statements.

Conclusion

Vim macros are a powerful tool for any developer who frequently edits repetitive text or code. By recording a sequence of keystrokes once and replaying it as needed, you can save considerable time and avoid manual errors.
