`rec` captures code evaluation and output, trying to preserve the R objects,
console output and conditions (messages, warnings and errors) emitted during
evaluation.
## Quick Start
`rec` operates in one of two ways, either recording an expression's evaluation,
or recording the top level interactive console. In both, cases, you can use
the singular interface, `rec()`. Once you've recorded evaluation, you
can also play it back!

### Record your console
Recording your console is started and stopped by running `rec()`. While
recording, you'll see a ":red_circle:" in front of your command prompt,
indicating that you're in a recording session.
```r
rec()
print(1:3)
# [1] 1 2 3
rec() # stop recording
play()
# print(1:3)
# [1] 1 2 3
```
### Record expression evaluation
Alternatively, you may want to capture evaluation in the background. This can be
A helpful alternative to `capture.output`, for situations where you want to
capture messages, but want to restructure the formatting or operate
```r
recording <- rec(print(1:3))
# [1] 1 2 3
play(recording)
# print(1:3)
# [1] 1 2 3
```
