How do I record a macro to swap two function arguments?

Explanation

This macro swaps two comma-separated arguments inside parentheses by cutting the second argument and placing it before the first.

How it works

1. qa — start recording
2. f, — find the comma
3. l — move past the comma
4. dt, or dt) — delete to the next delimiter
5. F( — find backward to the opening paren
6. p — paste after the paren
7. q — stop recording

Example

func(second, first)

Becoming:

func(first, second)

Tips

• This works for simple two-argument functions
• For more complex cases, use visual selection
• Text objects like i( help with nested parentheses
• The vim-exchange plugin provides more robust swapping
