# capture/start Install (or clear) the VM's echo capture buffer. Subsequent `echo`/`println` calls append to it instead of writing to stdout/stderr. Idempotent. ## Syntax

[capture/start]

## Examples

[capture/start]
echo "captured"
[capture/flush]    # → @("captured")

## Returns `nil`. Use `capture/flush` to drain the buffer, or `capture/with` for scoped capture. ## See Also `capture/flush`, `capture/clear`, `capture/with`
