synopsis: Show package descriptions with `nix flake show`
issues: [10977]
prs: [10980]
---
`nix flake show` will now display a package's `meta.description` if it exists. If the description does not fit in the terminal it will be truncated to fit the terminal width. If the size of the terminal width is unknown the description will be capped at 80 characters.
```
