Show HN: Pipec – utility to compose complex shell pipelines (github.com)

I have to edit pretty long pipelines really often, and doing so right in shell prompt isn't always convenient. What you get by using this tool:

* stage outputs are cached, so costly API call or SQL query are executed just once (of course, they are restarted if command changes) * preview of any stage output * it is possible to integrate it with shell to edit existing pipeline and get updated pipeline back in command line * copy any command or any stage output to clipboard

There are rough edges too:

* there is no scrolling right now * editor is pretty limited

To overcome these limitations there are keys to call you favorite pager and editor.
