# Macro Captured Runtime Variables

## Regex.

Capture text values from chat via `Chat Event` macro component, and store them in the bot's memory.

This is achieved through the Regex (If Regex Matches) filter type on the chat event. Values can be captured from chat via regex [named groups](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Regular_expressions/Named_capturing_group) (`(?<name>...)`), and then can be used in macros via the `%var:name%` text value. (see example below)
