How do I evaluate a Vim expression and paste the result directly from a register?

Q: How do I evaluate a Vim expression and paste the result directly from a register?

`"=strftime('%F') p` The expression register lets you compute text on demand and insert it without leaving Normal mode workflows. `"=strftime('%F') p` evaluates a Vim expression, stores the result in the expression register, then puts it into the buffer. This is useful when you need dynamic values such as timestamps, arithmetic results, or transformed strings while staying inside an operator/motion rhythm. ## How it works - `"=` opens the expression register prompt - `strftime('%F')` is the Vim expression being evaluated (`YYYY-MM-DD`) - ` ` confirms and stores the evaluated result - `p` puts that result after the cursor ## Example Given this line with the cursor on `DATE:`: ```text Release DATE: ``` Type: ```vim "=strftime('%F') p ``` Result: ```text Release DATE: 2026-03-27 ``` ## Tips - Replace `strftime('%F')` with any Vim expression, for example `toupper('abc')` or `line('.')` - The same expression-register idea also works in Insert mode and command-line mode when you need computed text inline
