# pipevcr

Record and play back pipes. Similar to what `script` does with the terminal but for pipes.

This can be used for debugging or testing where timing matters.

## Installation

```

pip3 install --user pipevcr

# or if you have pipx

pipx install pipevcr

```

## Usage

```

usage: pipevcr [-h] [-r] [-s SPEED] [-m MAX_PAUSE] FILE

pipevcr - the linux pipe recorder

positional arguments:

  FILE                  data file

options:

  -h, --help            show this help message and exit

  -r, --record          record pipe

  -s SPEED, --speed SPEED

                        playback speed, <1 to slow down, >1 to speed up

  -m MAX_PAUSE, --max-pause MAX_PAUSE

                        max pause time between outputs in seconds

```

## Record

You record a pipe with `-r`, e.g.:

```

(echo wait 1; sleep 1; echo wait 2; sleep 2; echo end) | pipevcr -r test.vcr

```

## Playback

And play it back with:

```

pipevcr test.vcr

```

## Faster

To speed it up (2=double):

```

pipevcr -s 2 test.vcr

```

## Slower

To slow it down (.5=half):

```

pipevcr -s .5 test.vcr

```

You can also set the maximum pause time separately:

```

pipevcr -m 1 test.vcr

```
