## Bonus: use `viv` with just standalone snippet (37LOC)
## Bonus: use `viv` with just standalone snippet (30LOC)
`--standalone` will auto-generate a mini-function version of `viv`
to accomplish the same basic task as using a local copy of `viv`.
After generating this standalone shim you can freely use this script
across Unix machines which have Python > 3.8.
across Unix machines which have Python > 3.8 and pip.
See [examples/black](https://github.com/daylinmorgan/viv/blob/dev/examples/black)
